Software / AI / Python Engineer — PBM Audit
New York, NY (Remote-friendly)
The opportunity
The U.S. pharmacy benefit management industry moves hundreds of billions of dollars a year — and much of it happens in the dark. PBMs sit between drug manufacturers, insurers, and patients, and their contracts are notoriously opaque. WriteWise exists to change that. We build data tools that give employers, health plans, and consultants the ability to actually understand what they're paying for and why.
We're profitable, well-funded, and growing fast. This isn't a "we might get there someday" story — we have paying customers, real revenue, and a product suite that's already reshaping how PBM audits get done. Now we're doubling down on automation and AI to do it at scale.
This role is the sole owner of our PBM Audit tool — a Python package that ingests pharmacy claims data, applies audit logic (formulary compliance, spread pricing, MAC discrepancies, generic substitution rates, rebate reconciliation, and more), and surfaces actionable findings. You'll take it from wherever it is today to wherever it needs to go. You design the architecture, you ship the code, you own the outcome.
What you'll actually do
Own the
ww-auditorPython package end to end: schema design, audit logic, output formatting, CI/CDBuild LLM-assisted audit workflows — using models to interpret ambiguous contract language, flag anomalies, and generate plain-English findings for non-technical stakeholders
Work directly with AWS (Lambda, S3, ECS/Fargate, EventBridge, Secrets Manager) to deploy and scale the tool in production
Collaborate closely with our operations and analytics team to translate messy, real-world PBM contract terms into clean, testable code
Participate in customer conversations — you'll understand why a specific audit logic matters, not just what it does
Contribute to adjacent tooling (we use LangGraph/LangChain, Pulumi IaC, Supabase, and Next.js across the stack)
What we're looking for
Must-haves:
Strong Python — you write clean, well-tested, production-grade code and you have opinions about how packages should be structured
AWS fluency — Lambda, S3, IAM, ECS; you've deployed things that actually run in production
GitHub proficiency — PRs, branch strategies, Actions/CI pipelines, code reviews
LLM integration experience — you've shipped something real that uses the OpenAI or Anthropic API, not just a side project that calls GPT
Business acumen — you can read a PBM contract clause and have a reasonable intuition about what it means financially. You don't need to be a PBM expert on day one, but you need to care about the domain and learn fast
Nice-to-haves:
Experience with healthcare data: NDC codes, drug pricing (AWP, WAC, MAC), pharmacy claims formats (NCPDP)
Familiarity with audit or compliance tooling
Experience building internal tools used by non-technical users
What you'll work with
Python · AWS (Lambda, S3, ECS, EventBridge) · LangChain / LangGraph · GitHub Actions · Pulumi · Supabase · PostgreSQL / Athena
Why WriteWise
Profitable and growing. We're not burning runway chasing a hypothesis — the business works, customers pay, and we're expanding.
Real domain impact. PBM transparency is genuinely broken. The tool you build will help plan sponsors recover real money and make better decisions.
Small team, high ownership. You won't be a feature factory. You'll have direct influence on architecture and product direction from day one.
No bureaucracy. We move fast. If you want to ship something, you ship it.
