About Unframe

Unframe is an AI-first startup helping the world’s largest enterprises bring LLM-powered applications to life in days – not months. We combine the speed of a product company with the flexibility of a consultancy, helping customers move from idea to deployed AI systems faster than anyone else in the market.

With over $100M in TCV secured within 12 months, and a new $50M Series B led by Highland Europe, Unframe is rapidly scaling globally alongside Fortune 500 customers, backed by Bessemer, Craft, and TLV.

About the role:

As a Senior Full Stack Software Engineer, you will lead a major product area end-to-end, shaping architecture and delivering production-ready AI-native applications.
You’ll take ownership of complex challenges, set a high bar for quality and execution, and work closely with Product and AI teams to build scalable solutions.

What you’ll do:

• Lead the architecture and delivery of a full-stack product vertical (backend + UI).
• Break down complex problems and drive them to production independently.
• Ship high-impact functionality quickly, then harden it for reliability and scale.
• Raise the bar for code quality, testing, observability, and performance.
• Mentor other engineers through design reviews, pairing, and technical guidance.
• Work closely with product, customers, and platform teams to define solutions that matter.

What we are looking for:

• 6+ years of experience building user-facing products end-to-end.
• Deep proficiency in JavaScript, TypeScript, Node.js, Vue/React, PostgreSQL (or other relational DB).
• Strong architectural instincts and the ability to design clean, scalable systems.
• Proven ability to take ownership of a problem from zero-to-one → production.
• Sharp communication, strong judgment, and fast learning ability.

Nice to have:

• Experience integrating AI/LLM capabilities into production apps.
• Background in multi-tenant systems, performance tuning, or platform work.

Why join us?

• Real ownership from day one. Drive decisions, shape ideas and make them work.
• Your fastest learning years. Build alongside founders and VPs in a space that moves weekly.
• You’ll have the opportunity to write and build what comes next.
