Back End Developer

Salary: $92,000 - 132,000 per year Requirements:

• Strong backend engineering skills in Python, Go, or C++; depth in one language is sufficient.
• Solid fundamentals in distributed systems, APIs, concurrency, performance, and testing.
• Working understanding of AI concepts such as LLMs, agents, RAG, embeddings, and common failure modes.
• Ability to read and reason about code written by others.
• Ownership mindset, including shipping, measuring, and fixing work.
• Nice to have: experience with static analysis, security tooling, or developer tools; familiarity with agent protocols such as MCP; background in applied math, statistics, or information theory; or experience in a startup or early-stage environment.

• Design and build backend services and analysis engines to validate AI-generated code and AI system behavior.
• Implement mathematically grounded, reproducible validation techniques rather than relying on LLM-as-judge approaches.
• Build high-throughput, reliable pipelines for local use, CI/CD, and customer environments.
• Integrate with AI coding tools, agent frameworks, and enterprise systems.
• Own services from design through production.
• Work directly with our founders and help shape the architecture.
