• Work across Engineering, Product, and Solutions to unblock customers and push the boundaries of AI adoption.

What We’re Looking For

• 2–5 years of software engineering experience.
• Strong proficiency in Python and Golang; comfortable shipping fixes in production systems.
• Hands-on experience with generative AI (LLM APIs, frameworks, building copilots or automations).
• Hands-on experience with OpenTelemetry and deep familiarity with distributed tracing concepts.
• Familiarity with AI frameworks (CrewAI, LangChain, LangGraph, Dify, LiteLLM, etc.).
• Familiarity or eagerness to learn JavaScript/TypeScript.
• Great debugger, creative problem solver, and fast learner.
• Independent and resourceful—you create solutions, not dependencies.

Bonus Points

• Experience in a customer-facing role.
• Built copilots, plugins, or custom GenAI-powered applications.
• Open-sourced or contributed PRs to real codebases.
• Experience working in a startup or fast-moving environment.
