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.

About the role:

You’ll be responsible for solving some of the most complex engineering challenges at Unframe. This role is deeply technical: designing architectures, debugging hard problems, improving core systems, and building reliable foundations for AI-native products.When something mission-critical needs to get done, you’re the engineer we trust.

What you’ll do:

• Own end-to-end architecture and implementation of complex backend and system components.
• Design scalable, reliable services that support high-velocity product development.
• Dive deep into hard problems across performance, data modeling, stability, and APIs.
• Partner with platform, applied AI, and fullstack teams to land robust, observable systems.
• Improve system reliability and developer experience through tooling, standards, and architecture.

What we are looking for:

• 6+ years in software engineering with strong evidence of owning complex systems.
• Deep proficiency in Node.js (clean backend architecture is key).
• Strong relational database fundamentals (PostgreSQL) and experience designing data models.
• Exceptional debugging skills and strong engineering judgment.
• Fast learner with the ability to ramp into new domains independently.

Nice to have:

• Experience with distributed systems, caching, messaging, or multi-tenant architectures.
• Experience integrating AI/LLM capabilities into backend systems.
• Infra or platform experience (observability, CI/CD tooling, APIs).

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.
