Job description

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 Full Stack Software Engineer, you'll work across the stack to design, implement, and ship high-quality workflows that solve real problems for real users. You'll collaborate directly with product and enterprise customers, see your code in production within days, and be part of a team that values ownership and thoughtful execution.

What you'll do:

  • Develop and deliver full-stack AI-powered applications on top of Unframe's platform.
  • Work closely with customers and internal teams to tailor solutions.
  • Extend the platform and UI/UX layer as needed.
  • Collaborate with platform and research teams to integrate AI capabilities into production use.
  • Write clean, tested, and maintainable code.

What we are looking for:

  • 5 + years of hands-on software-engineering experience.
  • Proven record of shipping real user-facing products end-to-end.
  • Proficiency with JavaScript, Node.js, Vue\React and PostgreSQL.
  • Strong communication skills and a product mindset.
  • Ownership mentality - comfortable taking a feature from idea to production.

Nice to Have:

  • Experience working with AI or LLM-based applications.
  • Experience working with B2B or enterprise customers.

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.
