Senior Engineer

Welcome to Frank:

We're an ambitious, VC-backed team of builders with international experience across startups and scale-ups in Insurtech, AI & Robotics, e-commerce and travel tech. Our mission is to reinvent the traditional world of insurance with the speed, creativity and intelligence of next-generation technology.

Based in the heart of Lisbon, we work from a bright, sunny office just steps from cafés, culture and the city's vibrant startup scene. Our hybrid model gives us the best of both worlds: the flexibility to work from anywhere, combined with the energy of real face-to-face collaboration.

Joining a fast-moving startup means shaping the future from day one. Every idea, every project and every line of code has a direct impact. In our small, talented team, everyone has a voice and room to grow — while gaining international exposure and learning from founders who've scaled companies across industries and markets. And it all happens in Lisbon, one of Europe's most exciting innovation hubs, with a lifestyle to match.

What you'll do:

Build & Scale: design, develop, test, deploy and maintain high-performance backend services and APIs that power our platform.

Own the Data: work with databases end to end — structure, optimization and integrity — so the product stays fast and reliable as we grow.

Collaborate: partner closely with product, design and engineering to ship features that matter.

Optimize: monitor performance, troubleshoot issues, and continuously strengthen our backend infrastructure.

Innovate: bring ideas to the table on technical challenges and where the product goes next.
