Your job is to take a business problem from one of those teams, work out where a model helps and where it does not, and deliver something the team uses every day. This is not a research role. The AI work lives inside our production platform, so you will also ship application features, work with the integrations that exchange data with our partners and build the test and quality practices that keep all of it reliable. Our clinical programs are the first area we are transforming with AI, so your early work will be with the clinical team and the documents, reviews, and decisions that run through it. Other business areas follow as the platform stabilizes. The role is remote, with structured written communication as the default working mode. You report to the Head of Engineering and work directly with the business owners of the problems you solve. **What you will do** * Build and extend LLM\-backed capabilities on AWS Bedrock and related models: document OCR and extraction on clinical and claims paperwork, summarization and decision support for clinical review, Knowledge Bases for retrieval over plan and policy documents, and workflow automation for internal teams * Establish and maintain evals for the AI features you ship, so we know when quality drifts * Handle the practical side of production AI: structured output, failure modes, cost, latency, and knowing when a deterministic approach beats a model * Use agentic coding tools (Claude Code and Kiro) as a core part of your workflow, and own the verification of what they produce * Design, build, test, and ship features in our Python and FastAPI back e
