Senior Full Stack Engineer, Optix

• 6+ years of full-stack engineering experience, with a track record of reliably delivering features end to end
• Strong backend fundamentals, including building and scaling APIs (REST and/or GraphQL) and a solid grasp of databases and data-flow patterns
• You've built something real with LLM APIs and understand in practice how they behave, including their quirks and failure modes
• You are comfortable in Python and familiar with the LangChain ecosystem
• You understand that AI features demand different thinking about quality, testing, and UX than deterministic features
• You use AI tools (e.g. Claude) fluently to accelerate and debug your own engineering
• Strong problem-solving and systems thinking about integration patterns
• Comfort with Git, unit testing, CI, and the Linux command line, plus a habit of writing maintainable, testable code in complex systems
• You can clearly articulate technical reasoning to technical and non-technical teammates, and work well both independently and collaboratively
• We welcome applicants from all walks of life. Even if you don’t feel you meet every requirement listed, we would still love to hear why you think you would be an awesome addition to our team, and we encourage you to apply
