Senior Full-stack Engineer

London, UK | Full-time | Hybrid

About Beams

At Beams, we’re transforming home renovation – making it simpler for homeowners and greener for the planet.

We believe that renovating a home should be just as special as living in one. The process should be easy and exciting, not overwhelming. But today, home renovation is often complex, stressful, and full of uncertainty. That’s why we’re rethinking it from the ground up – using technology to match homeowners with the right plan, the right design, and the right people to deliver high-quality, energy-efficient renovations.

Since launching in 2022, we’ve built an end-to-end service that guides homeowners through every step of the renovation journey, from planning to design to build. And because we believe the green choice should always be the easy choice, we’re helping people create more energy-efficient homes for a better future for all.

At Beams, we move fast, challenge the status quo, and tackle big problems with bold ideas. We value action, simplicity, and positive energy, fostering a culture of openness and always doing the right thing—for homeowners, for builders, and for the planet.

If you’re excited by the opportunity to reshape an industry and make a real impact, we’d love to hear from you.
