Job Description

We are seeking an AI Software Engineer to build reliable, production-grade AI features and systems across our venture portfolio. You will work on the end-to-end stack that powers AI-enabled products, including model integrations, backend services, data pipelines, evaluation harnesses, and safety and reliability tooling.

Preferred Qualifications

• Proficiency in Python and at least one backend language (e.g., TypeScript/Node.js, Go, or Java).
• Experience integrating LLM APIs or open-source models, including prompt design and structured output patterns.
• Familiarity with ML/AI infrastructure concepts such as embeddings, vector search, retrieval, and model evaluation.
• Comfort with cloud services (AWS, GCP, or Azure), CI/CD, and observability (logging, metrics, tracing).
• High attention to detail and discipline in testing, monitoring, and documentation.
• Ability to work in ambiguity and iterate quickly with product, design, and operations.

Key Responsibilities

• Build AI-enabled features and internal tools that improve user value and team execution.
• Implement model and tool integrations (LLMs, vector DBs, search, workflow automation) with strong reliability and security practices.
• Design and maintain evaluation workflows to measure quality, correctness, latency, and cost.
• Improve system observability and guardrails to ensure safe, consistent behavior in production.
• Collaborate cross-functionally to translate product needs into robust technical solutions.

Why Apply

You will work close to real product problems, ship AI features end-to-end, and develop strong judgment for what it takes to make AI systems reliable in production.
