Who we are

Lysk is a European defence startup. Our mission is to create modern software tailored for hostile environments. Backed by Project A, Europe’s leading defence VC, and angels including the founders of Cloudflare, Quantum Systems, and ElevenLabs, we’re assembling a world-class team at the intersection of modern software and defence. We do not work on weapons systems or hardware products.

Our founding team includes two early Cloudflare employees and a former GIGN commander (French special forces). We're actively looking for an experienced generalist engineer to join us as our first hire and help us reach product-market fit.

What you’ll work on

You’ll work closely with the founders to iterate quickly on prototypes and evolve our early stack.

Initially, your focus will be on the frontend and design side (rapid prototyping, JS frameworks), with an upcoming shift toward backend work — primarily in Python, focusing on bespoke audio streaming tech and real-time voice systems.

Who we’re looking for

A pragmatic, product-minded generalist with strong execution skills and a desire to build from zero. You might be especially excited about this if you:

• Have experience with frontend frameworks and building real-time user interfaces
• Are comfortable diving into audio processing and low-latency systems
• Want your work to have real-world impact, helping those who serve
• Thrive in ambiguous, fast-moving environments

Location

• We’re currently hiring in Warsaw 🇵🇱 and Paris 🇫🇷
• We have an in office culture and can sponsor relocation, if required

Sounds like you? Let’s talk.
