skills: ml, full-stack, llm, api, infra, benchmarking, dataset building, enterprise ai

🚀 Ready to build something big, fast, and meaningful? Join us at Tecto as our very first engineer and help invent how enterprises trust and adopt AI.

We’re building the enterprise AI governance 🤖👩‍💻 — protecting privacy and monitoring the explosion of AI tools flooding into companies. Already live with law firms ⚖️ and piloting with Big 4 consulting firms and large enterprises, we’re on a mission to make AI adoption safe, smart, and unstoppable.

What you’ll actually be doing (aka the fun stuff):

🧪 Dream up and run application-level benchmarks: scenario testing, dataset building, LLM-as-a-judge evaluations
🔌 Wrangle the wild world of integrations, plugging into dozens of third-party AI tools + enterprise APIs
🎨 Build slick dashboards + APIs that turn compliance spaghetti into crystal-clear visuals
🌱 Shape the engineering culture from scratch (yes, your commits set the tone for future hires)

Why this role rocks:

💥 Impact: Your code defines the product, not a Jira ticket backlog
🧠 Learning: Founders are ex-Google AI + PhD consultant; you’ll be in the weeds of frontier AI problems
🎯 Ownership: Full-stack means you touch everything from LLM evals → infra → customer pilots
🌟 Culture: We’re scrappy, ambitious, and love solving tough problems — but outside of work you’ll find us skiing, climbing, or chasing an adrenaline rush 🧗‍♀️⛷️🚴. We’re fun, active, and believe building a company should be an adventure too.

This isn’t just a job — it’s your chance to help build the platform that will govern the world’s AI workforce 🌎.
