Founding AI Engineer

The Role

What You'll Do

• Product Development: Build core features that make Jetty a faster, smarter, and more delightful product.
• LLM Engineering: Design systems where models are components in larger workflows — not just chat endpoints, but nodes that generate, validate, and compose structured outputs. You'll shape context architecture, memory systems, and the configurations that let intelligence flow through the product.
• Infrastructure & Reliability: Work around the full lifecycle of code — CI/CD, deployments, observability. Build systems that scale gracefully and fail safely.
• Work with Hard Data: Health data is sparse, vague, and temporal. You'll build systems that extract signal from conversational inputs without imposing false precision.
• Build & Iterate: We invest in foundations where they compound, and move fast on everything else. You'll do both.

What We're Looking For

• 3–6+ years experience as a software engineer.
• Strong in Python
• Instincts for reliability, scaling, security, and observability.
• Comfortable operating in ambiguity and early-stage chaos. You should be comfortable with rapid iteration and high expectations for both speed and quality. As a result, you’ll be able to own meaningful projects end-to-end.
• Experience with (or genuine excitement for) creative LLM engineering—not just calling endpoints, but shaping model behavior through context design and system architecture.
• Bonus:
  • Swift, frontend skills, or experience with real-time systems.
  • Experience with strongly typed or compiled languages (Go, Rust, Java, etc.)
  • Experience with real-time systems

What We Offer

• The opportunity to build a product that genuinely changes how people manage their health.
• Competitive salary & meaningful equity package.
• Real ownership and impact from day one.
