About The Position

Pairtu is building the AI operating system for care navigation—a platform that blends high -touch human support with AI -driven workflows. The market is massive ($60B+), the need is urgent, and the founders have personal stakes in solving it.

They’ve raised VC funding, have healthcare traction, and now need a founding engineer who codes at an experienced level and knows how to apply AI in production. This person will architect, build, and ship the core product while collaborating directly with the founders on technical and product decisions.

Requirements

• 5+ years full -stack experience with backends like Ruby on Rails, Python/Django, or Elixir/Phoenix plus React/Next.js or similar frontends
• Shipped production code in healthcare or another regulated industry
• Fluency in AI development including prompt engineering, fine -tuning, API integration, vector databases, and retrieval -augmented generation pipelines
• Experience designing secure, HIPAA -compliant systems
• Background with RESTful APIs, relational databases, and cloud hosting (AWS, GCP, or platforms like Aptible/Fly.io)
• Currently 80%+ hands -on coding and want to stay that way
• Ability to thrive in startup environments and contribute to technical and product decisions

Nice To Haves

• AI development at other startups, electronic health records or claims systems, internal tooling or workflow automation, DevOps and continuous integration for small teams, or Django and Python expertise.

Responsibilities

• Ship the Core Platform: Design, build, and launch patient - and advocate -facing apps, backend services, and integrations. Move fast while managing technical debt intentionally.
• Build AI -First Workflows: Use large language models, APIs, and custom models to automate intake, triage, and follow -up. Integrate AI into daily tools advocates use, from summarization to proactive care nudges.
• Develop the Tech Roadmap: Translate ambiguous product needs into clear, buildable solutions. Decide what to build in -house versus integrate via third -party APIs.
• Collaborate Cross -Functionally: Work with clinical, operations, and growth leads to ensure the product solves real user problems. Join early customer calls to see pain points firsthand.

Benefits

• Base Salary: $150k–$220k
