# Domain Expert – Pharmacy (UpToDate Lexidrug)

**To qualify you must use UpToDate Lexidrug (or Lexicomp) regularly - weekly or more - as a working part of your job, with 2+ years of professional pharmacy experience.**

Lexidrug knowledge we require

**Core (required of all candidates)**

- Knows how to work a full medication-list interaction check to completion — not just confirm a single named pair, but judge severity ratings and mechanism of interaction across the whole list
    
- Knows how to weigh contraindications, boxed warnings, and warnings/precautions against a specific patient's situation, not just check whether a flag exists
    
- Knows how to distinguish "not contraindicated" from "appropriate for this patient" — and where in the monograph that second judgment actually gets made
    
- Knows how to reconcile a Special Alert against monograph content when they conflict — recognizes alerts generally take precedence until reconciled
    
- Knows how to apply renal/hepatic dose-adjustment logic and calculators correctly given current patient data (labs, weight), not just plug in numbers
    

**Specialized depth (strong working knowledge in at least 2–3 of the following)**

- Trissel's IV Compatibility (physical/chemical incompatibility vs. physiological interaction — knows these are distinct problems, not one nested in the other)
    
- Pediatric/weight-based dosing
    
- Beers Criteria / geriatric-specific precautions
    
- Pregnancy and lactation risk categories
    
- REMS and prescribing/access restrictions (controlled substance scheduling, restricted distribution programs)
    
- Therapeutic class comparison for alternatives (allergy, shortage, formulary substitution)
    
- Drug I.D. and patient education / multi-language handouts
    

What you'll do

- Confirm an interaction, dosing, or contraindication finding holds up against the patient's **full** medication list and chart — not just the two drugs named in the question
    
- Catch missed interactions, stale patient data (outdated labs/weight) driving a wrong dose, and monograph guidance superseded by a newer Special Alert
    
- Judge completeness: is the full clinical picture (all active meds, current labs, comorbidities) accounted for, or was the question scoped too narrowly
    
- Distinguish "permitted" from "appropriate" — flag when a drug clears interaction/contraindication checks but is still a poor choice for this specific patient
    
- Verify that a correct clinical conclusion is actually **carried through** — order updated, prescriber notified, chart/note documented — not just identified and left there
    

Requirements

- **Frequent Lexidrug (or Lexicomp) use - weekly or more - in your current or recent role**
    
- **2+ years of professional pharmacy experience, inpatient/hospital setting strongly preferred**
    
- Reflexive use of Interactions, Trissel's, and monograph sections; can spot a missed interaction, a stale dose calculation, or superseded guidance on sight
    
- PharmD and active pharmacy license, or equivalent verification-heavy clinical experience
    
- Strong working knowledge in at least 2–3 specialized areas above, tied to your practice setting (e.g., ICU, oncology, pediatrics, geriatrics)
    
- Comfort judging whether a correct clinical finding was properly followed through into the chart, order, and care-team communication
    
- Prior data annotation, labeling, or AI evaluation experience is a plus

We're looking for experienced machine learning researchers with hands-on experience training and improving deep learning models end-to-end, across vision and language. You'll work on well-scoped empirical open-ended ML research problems.

## Responsibilities

- Train image classifiers and generative image models from scratch, and fine-tune open-weight language models.
- Get the most out of limited data, compute, and model-size budgets.
- Make models robust — to adversarial inputs and to adversarial conversations.
- Compress models to meet hard size and latency constraints without sacrificing accuracy.
- Diagnose and resolve training issues.

## Requirements

We are looking for candidates with strong expertise in one or more of the following areas:

**Adversarial Robustness**

Experience with:
- Adversarial training of image classifiers (e.g. PGD-based training, TRADES).
- Evaluating robust accuracy under standard threat models (e.g. L∞ attacks, AutoAttack) and avoiding gradient-masking pitfalls.
- Managing the robustness–accuracy trade-off and robust overfitting.

**Efficient Computer Vision**

Experience with:
- Training image classifiers end-to-end, especially for fine-grained recognition (many visually similar classes, few examples per class).
- Model compression: quantization, pruning, and knowledge distillation from large teachers into small students.
- Deploying models under hard size or latency budgets (on-device, edge, or embedded settings).

**Generative Image Modeling**

Experience with:
- Training image generative models from scratch: diffusion models, GANs, VAEs, or flow-based models.
- Iterating against sample-quality metrics such as FID.
- Training-efficiency tricks that produce good generators quickly and at small parameter counts.

**LLM Post-Training & Behavioral Robustness**

Hands-on experience with one or more of:
- Supervised fine-tuning and preference optimisation (DPO, RLHF, RLAIF) of open-weight language models, including building your own datasets via synthetic generation, noisy or weak supervision, and rejection sampling.
- Shaping conversational behaviour over multiple turns: resistance to persuasion and sycophancy, calibrated confidence, and knowing when to accept corrections.
- Alignment-style fine-tuning that changes a specific behaviour while preserving general capability.

**Multilingual Pre-training**

Experience with:
- Training multilingual or low-resource-language models from scratch.
- Tokenizer design across scripts and typologically diverse languages.
- Balancing highly unequal per-language data (sampling temperatures, cross-lingual transfer) in data-constrained regimes.

**Additional Areas of Interest**

Experience in any of the following is a plus:
- Scaling laws and training-efficiency research.
- Curriculum learning and data ordering.
- Model evaluation: benchmark construction, contamination control, statistically sound comparisons.
- Uncertainty estimation and model calibration.
- Data augmentation and synthetic data for robustness.

## General Qualifications

- 3+ years of machine learning research experience (PhD research counts toward this requirement).
- Strong experience with PyTorch, JAX, TensorFlow, or similar ML frameworks.
- Degree from a top-100 university, experience at a FAANG or comparable AI company, or an equivalent research track record through publications or impactful open-source contributions.

## Why Join

- Work on cutting-edge machine learning research.
- Collaborate with leading AI researchers on challenging, high-impact projects.
- Flexible, project-based work with competitive compensation.

- Production experience in at least one of Python, Java, Rust, C#, or C++, plus working proficiency in a second language — this cohort is intentionally staffed across multiple language ecosystems.
    
- Hands-on experience across the stack: backend services and APIs, a modern front-end framework (React or equivalent), relational or document databases, and cloud deployment.
    
- Demonstrated ability to onboard onto an unfamiliar codebase and deliver working code quickly with minimal ramp-up.
    
- Demonstrable career progression.
    
- Ability to engage reliably for at least 40 hours/week during weekdays.
    
- Strong written communication skills and the ability to explain complex technical decisions clearly.

We're looking for engineers who have shipped production search systems (especially agentic ones now that we're in the era of LLMs and agents) and are thinking hard about the requirements and optimizations of those systems.

You've probably:

- Owned relevance or retrieval on a system real users depended on
    
- Decided how to quantify impact and improvements with these systems.
    
- Built out systems related to agentic search.
    
- Scaled data infrastructure to power modern search systems.
    

This is a 25-minute conversational interview. No coding, no take-home. We want to hear how you actually think about search quality, evaluation, and the tradeoffs you've made in real systems. Bring war stories — the messier and more specific, the better.

If your interview stands out, we'll follow up with a paid 30-minute live conversation with our team — $200 for your time, paid on completion of the call.

If that sounds like you, apply and complete the interview. We review every submission.

**Why This Role Exists**

At Mercor, we believe the safest AI is the one that’s already been attacked — by us. We are assembling a red team for this project - human data experts who probe AI models with adversarial inputs, surface vulnerabilities, and generate the red team data that makes AI safer for our customers.

This project involves reviewing AI outputs that touch on sensitive topics such as bias, misinformation, or harmful behaviors. All work is text-based, and participation in higher-sensitivity projects is optional and supported by clear guidelines and wellness resources. Before being exposed to any content, the topics will be clearly communicated.

**What You’ll Do**

- Red team conversational AI models and agents: jailbreaks, prompt injections, misuse cases, bias exploitation, multi-turn manipulation
    
- Generate high-quality human data: annotate failures, classify vulnerabilities, and flag systemic risks
    
- Apply structure: follow taxonomies, benchmarks, and playbooks to keep testing consistent
    
- Document reproducibly: produce reports, datasets, and attack cases customers can act on
    

**Who You Are**

- You bring prior red teaming experience (AI adversarial work, cybersecurity, socio-technical probing)
    
- You’re curious and adversarial: you instinctively push systems to breaking points
    
- You’re structured: you use frameworks or benchmarks, not just random hacks
    
- You’re communicative: you explain risks clearly to technical and non-technical stakeholders
    
- You’re adaptable: thrive on moving across projects and customers
    

**Nice-to-Have Specialties**

- Adversarial ML: jailbreak datasets, prompt injection, RLHF/DPO attacks, model extraction
    
- Cybersecurity: penetration testing, exploit development, reverse engineering
    
- Socio-technical risk: harassment/disinfo probing, abuse analysis, conversational AI testing
    
- Creative probing: psychology, acting, writing for unconventional adversarial thinking
    

**What Success Looks Like**

- You uncover vulnerabilities automated tests miss
    
- You deliver reproducible artifacts that strengthen customer AI systems
    
- Evaluation coverage expands: more scenarios tested, fewer surprises in production
    
- Mercor customers trust the safety of their AI because you’ve already probed it like an adversary

As a Government & Public Policy Expert, you will apply your professional judgment to author, review, and stress-test tasks spanning the full policy and administrative lifecycle — policy analysis and memo drafting, regulatory drafting and compliance review, procurement and contracting, program and grants management, budget and appropriations, and legislative affairs. Your expertise directly shapes how advanced AI models reason about the decisions that agencies, legislatures, and public institutions face every day.

## Key Responsibilities

- Design realistic public-sector scenarios and tasks drawn from your hands-on experience: policy options analysis, decision memos, briefing papers, and issue backgrounders for senior officials.
    
- Build and review regulatory work products — proposed and final rule text, preambles and regulatory impact discussion, public-comment analysis, guidance documents, and compliance determinations against controlling statute and regulation.
    
- Create procurement and contracting exercises grounded in real practice: requirements and statements of work, RFP/solicitation development, FAR and agency-supplement analysis, evaluation criteria, source-selection rationale, and contract administration issues.
    
- Develop program and grants management tasks covering notices of funding opportunity, application review and scoring, subrecipient monitoring, performance measurement, and reporting obligations.
    
- Author budget and appropriations tasks — budget justifications, spend plans, reprogramming and apportionment questions, cost estimates, and fiscal-law issues such as purpose, time, and amount.
    
- Draft legislative affairs materials, including bill analysis, fiscal notes, amendment tracking, testimony preparation, and constituent or stakeholder correspondence.
    
- Review and grade AI-generated outputs for accuracy, completeness, procedural soundness, and fidelity to the governing authority; identify subtle errors, edge cases, and failure modes in model reasoning.
    
- Provide clear, structured written rationale explaining why a given answer is correct, incomplete, or wrong, and collaborate with the team to refine evaluation rubrics and raise the quality bar for this domain.
    

## Ideal Qualifications

- 3+ years of professional experience in government, public policy, or regulatory affairs.
    
- Federal, state, local, tribal, and agency-adjacent experience is all welcome — including civil service and political appointments, legislative staff, regulatory agencies, public authorities and special districts, government contractors and consultancies, think tanks, trade associations, advocacy organizations, and in-house government affairs or regulatory teams.
    
- Depth in one or more sub-domains: policy analysis and memo writing, rulemaking and regulatory compliance, procurement and contracting (FAR, RFP/solicitation, source selection), program and grants management, budget and appropriations, or legislative affairs.
    
- Working command of the administrative process — how authority flows from statute to regulation to guidance to implementation — and of the tradeoffs, constraints, and stakeholders that shape real public decisions.
    
- Excellent written communication, with the ability to explain nuanced reasoning clearly and concisely for a decision-maker audience.
    
- Sharp attention to detail, citation discipline, and comfort evaluating the quality of others' work.
