Job Description


Who we are

Lysk is a European defence startup. Our mission is to create modern software tailored for hostile environments. Backed by Europe’s leading defence VC, and high-profile angel investors, 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 customer facing founding engineer to help us with our first deployments, while we reach product-market fit.


What you’ll work on

You’ll work closely with the founders to iterate quickly on deployments of our prototypes with early customers. This role is focused on the French market.


You should be prepared to get your hands dirty with bespoke audio streaming tech and real-time voice systems.


Your job is to close the gap between what our product does generally, and what our customers require specifically. This might involve rapid prototyping, implementing quick fixes, and generally doing things that don’t scale


We’ll need your help with:

  • Technical Enablement & Solution Design
  • Onboarding & Implementation
  • Product Feedback & Field Insights
  • Support & Technical Documentation


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 implementing AI systems in resource constrained environments
  • Are comfortable diving into audio processing and low-latency systems
  • Want your work to have real-world impact, helping those who serve
  • Have experience working with armed forces
  • Thrive in ambiguous, fast-moving environments
  • Are able to clearly communicate complex technical systems in simple ways
  • Must be a native French speaker & have ability to get French security clearance.


Location & Compensation

  • We’re currently hiring in Paris 🇫🇷 (we have other roles in Warsaw 🇵🇱 too)
  • Frequent travel will be required (in and out of France)
  • We have an in office culture and can sponsor relocation, if required
  • Compensation will depend on experience; expected range €60–100K + generous equity (BSPCE)
