Job Level

About the role

  • Design, build, and maintain scalable TypeScript/Node and Python services and RESTful or gRPC APIs that integrate with agentic GenAI systems
  • Implement and extend Angular/TypeScript UI components for web experiences
  • Optimize MongoDB and PostgreSQL queries and service performance
  • Collaborate with cross-functional squads to define requirements and deliver features
  • You will work on AI Agents, MCP servers and various other AI enabled tools and frameworks and so must be comfortable working with ambiguity and rapidly evolving technologies
  • Identify and drive process, architecture, and toolchain improvements
  • Mentor junior engineers (code reviews, pair-programming etc)
  • Serve as a technical lead for complex projects, balancing scope, risk, and not compromising deliverable quality.

Requirements

  • 8+ years building web services or full-stack applications
  • Strong hands-on experience in TypeScript/Node, Python or similar backends
  • Experience with Angular/TypeScript
  • Deep understanding of APIs, PostgreSQL, and some performance tuning
  • Proven ability to balance short-term delivery with long-term technical investments and continuous improvement of quality.
  • Comfortable working in a fast-paced, ambiguous environment where requirements evolve over time.
  • Excellent problem-solving, communication, and collaboration skills
  • Some knowledge of AI/ML is desired but not a requirement
  • Experience with LLMs or AI-driven toolchain (Langchain/Langgraph) is highly desirable
Benefits
  • A generous PTO policy, with a minimum of three weeks off per year
  • A holiday schedule that follows standard U.S. holidays
  • Free therapy coverage benefits to ensure employees have access to the care they need (must be enrolled in a qualifying medical plan to participate)
  • Competitive Medical, Dental, and Vision coverage, with plans to meet every need — including HSA (with $1,100 company contribution) and FSA options
  • Employer-paid short-term disability, long-term disability, life & AD&D, plus coverage of the salary difference for up to seven weeks of short-term disability leave (after the required waiting period)
  • Eight weeks of paid Parental Leave; if the parent also qualifies for STD, this benefit is in addition, allowing for 8–16 weeks of paid leave
  • 401(k) retirement plan with 100% match on up to 4% of base salary, immediately vested
  • Join teammates from across the country at our annual company gathering
