Senior Software Engineer

Role Overview

• Deliver large projects that introduce new product capabilities, often acting as a maintainer for key code repositories.
• Break down complex problems into manageable tasks, ensuring steady and predictable delivery while identifying and resolving root causes of incidents.
• Collaborate with your team to roadmap and execute ambitious technical strategies, balancing short-term and long-term trade-offs.
• Mentor and support junior engineers, providing thoughtful code reviews and real-time pairing.
• Design and build AI-powered clinical agents using LangGraph.js for stateful orchestration, composing multi-node StateGraphs that handle context gathering, LLM reasoning, and action execution within a shared NestJS service.
• Integrate LangSmith for end-to-end AI observability, including prompt versioning and management via LangSmith Hub, automated per-node tracing, evaluation pipelines with golden datasets, and CI-gated quality checks that block regressions before merge.
• Develop and maintain agentic workflows that leverage LLMs (Claude Sonnet via AWS Bedrock)
• Contribute to the Member-Centric Knowledge Graph and RAG-based retrieval systems that give agents the clinical context, causal evidence, and relationship awareness needed for intelligent decision-making.
• Proactively improve the maintainability, availability, and performance of the team's features, and contribute to the team's overall architecture and developer tooling.
• Communicate technical ideas clearly to both technical and non-technical partners, and document solutions for future reference.

• Bachelor’s Degree (or equivalent) in Computer Science, Engineering or related technical field
• 5+ years of non-internship full time professional software development experience
• 3+ years of work experience Node JS/ Typescript
• Experience with using AI tools such as Github copilot or Cursor
• Experience delivering large software projects or features in a production environment.
• 1+ years of hands-on experience building applications with LLMs, including prompt engineering, model integration (e.g., OpenAI, Anthropic/Claude, AWS Bedrock), and evaluating AI output quality
• Experience with agentic AI frameworks such as LangGraph, LangChain, or similar orchestration libraries for building stateful, multi-step AI workflows
• Familiarity with LangSmith or equivalent AI observability/evaluation platforms for tracing, prompt management, and regression testing of LLM-powered features
• Understanding of responsible AI practices including PHI/PII handling, guardrails, and output validation in healthcare or regulated environments.
