Software Engineer, Full Stack (Python, Java, Rust, C#, C++)

To qualify you must work regularly in a professional inpatient CDI or coding role — hospital CDI (specialist or leadership), inpatient DRG coding/auditing, or clinical-documentation denial management — with 2+ years of experience under ICD-10-CM/PCS and the MS-DRG system.

## Clinical documentation knowledge we require

**Coding & the pre-bill cycle**

- ICD-10-CM/PCS assignment, POA reporting, and the inpatient DRG assignment and reimbursement cycle
    
- Concurrent and retrospective (pre-bill) review, DRG reconciliation (working vs. final), and tie-out of coded diagnoses to source documentation in the record
    

**Judgment & evaluation**

- CC/MCC impact and DRG movement; when a diagnosis does or doesn't change the DRG, severity of illness, or risk of mortality
    
- Code changes and their coupled effects (principal-diagnosis sequencing, DRG shift, dollar and quality impact)
    

**Clinical standards & criteria**

- Applying published clinical criteria to the record — AKI staging (KDIGO), sepsis, respiratory failure, malnutrition, CKD staging — and UHDDS reporting rules
    
- Distinguishing a clinically supported diagnosis from an unsupported or templated/copy-forward one; clinical validation
    

**Query & compliance discipline**

- AHIMA/ACDIS-compliant, non-leading query construction; when a query is required versus when specificity is already provider-documented
    
- The bright line: indicators justify a query, never a code — never add, delete, or change a provider-documented diagnosis without a provider response
    

**Documentation & evidence**

- Query vs. CDI-review vs. note standards, hold/pending mechanics, review-ready completeness
    
- Evidence provenance: a lab value, document, baseline, or DRG figure is only valid if it is actually in the record and produced by the grouper, not asserted
    

**Tools**

- Comfort in professional CAC/CDI software — computer-assisted coding and CDI workflow platforms (e.g., Dolbey Fusion, 3M 360 Encompass, Nuance/Optum360), DRG groupers, and EHR systems (e.g., Epic)
    

## What you'll do

- Review AI-agent attempts at realistic CDI/coding tasks and judge whether each disposition is correct and adequately supported by the record
    
- Confirm work is actually completed and recorded — codes changed, queries sent (not left in draft), holds placed, DRG recomputed, notes and CDI reviews filed — not just described
    
- Catch fabricated or overstated work: cited labs, documents, or prior encounters that don't exist, a claimed provider response that never came, DRG or dollar figures not produced by the grouper
    
- Judge completeness and whether the right action was applied to the right chart — code fix vs. query vs. clinical-validation query vs. leave-alone — and require verify-before-finalize
    
- Write clear, specific agree/disagree rationales on each attempt
    

## Requirements

- 2+ years of professional experience in one or more of: inpatient hospital CDI (specialist or leadership), inpatient DRG coding/auditing, or clinical-documentation denial management
    
- Current or recent hands-on work under ICD-10-CM/PCS and MS-DRGs
    
- Reflexive professional judgment; can spot an unsupported diagnosis, a leading query, a missed CC/MCC, or a rubber-stamped account on sight
    
- CCDS, CDIP, CCS, RHIA/RHIT, or RN with CDI experience (or equivalent); hospital, coding, or HIM background
    
- Comfort working inside CAC/CDI software and reading the full clinical record — H&Ps, consults, progress notes, discharge summaries, labs, and flowsheets

**Assessment**
An earnings release and prepared remarks from a mock results pack; a guidance revision recommendation; an activist vulnerability assessment.

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.

**Fluent Language Skills Required:** English & Norwegian. Native fluency in English and Norwegian is required for this position.

**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
    

**Why Join Mercor**

- Build experience in human data-driven AI red teaming at the frontier of safety
    
- Play a direct role in making AI systems more robust, safe, and trustworthy

Data Scientist Talent Network

## Role Overview

Mercor is partnering with a leading AI lab to build a network of government, public policy, and regulatory affairs experts who help train and evaluate frontier AI systems on real-world public-sector work. 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.
    
- A relevant credential or degree (MPP, MPA, JD, CFCM/CPCM, PMP, or comparable) is preferred but not required — demonstrated hands-on experience matters more.

Lawyer — O*NET Occupation Study

**About this study**

Mercor is building a new, more accurate version of O\*NET — the U.S. government's framework for describing occupations and the tasks they involve. We are gathering input directly from experienced practitioners to improve how the work of software developers is described.

**About the role (SOC 15-1252.00 — Software Developers)**

Software developers research, design, and build computer software, network software, or specialized utility programs. They analyze user needs, determine the feasibility of designs within time and cost constraints, and develop software solutions by applying principles of computer science, engineering, and mathematical analysis. Their work spans the full development lifecycle: defining specifications and performance requirements, architecting systems, directing testing and validation procedures, and modifying existing software to correct errors, adapt to new hardware, or improve performance. They may coordinate with hardware engineers to integrate hardware and software systems, and they often own decisions about system design rather than executing designs handed to them.

**This occupation excludes**

- **Web developers (15-1254.00)**, whose work centers on developing and implementing websites, web applications, and interactive web interfaces. A worker whose primary responsibility is building or maintaining websites, optimizing website performance, or integrating websites with other applications is a web developer, even if they write substantial application code. The distinguishing test is the artifact: web developers produce web properties; software developers produce software systems and applications more broadly, of which the web may be one deployment surface among many.
    
- **Computer programmers (15-1251.00)**, who create, modify, and test code working from specifications drawn up by software developers or others. The distinguishing test is authorship of the design: programmers implement designs they are given, while software developers analyze requirements, produce the design, and direct development. A worker who primarily writes and debugs code to someone else's specification is a programmer, not a developer.
    

**What you'll do**

- Complete a one-time online survey/interview about your day-to-day work as a software developer. It takes **up to 30 minutes**.
    
- There may be an optional follow-up survey, task, or short interview afterward, which would be paid separately.
    

**Who we're looking for (eligible applicants have)**

- **4+ years of experience working specifically as a software developer.**
    
- **Current work, or work within the last 12 months, in the role.**
    
- **Direct knowledge of design, coding, and deployment tasks.**
    
- **U.S.-based.**
    

**Not eligible (common confounders)**

- Software QA analysts and testers whose role is testing rather than development (SOC 15-1253.00).
    
- IT support, help desk, or system administrators who do not develop software.
    
- Computer programmers (SOC 15-1251.00).
    
- Web developers (SOC 15-1254.00).
    
- Computer systems analysts (SOC 15-1211.00).
