Working Student Software Engineer (m/f/d), On-Site Bochum

Variant Security

Bochum, DEOn-site

About the Role

About Variant Security

Variant Security is securing the world's critical fleets for the AI era. Nearly every device runs identical software, so a single exploit can cascade across an entire fleet, and AI has made finding that exploit cheaper than ever. Variant breaks that pattern, so compromising one device gives an attacker nothing against the rest. AI made exploits cheap. We make them useless. We're building our engineering team in Bochum.

As a working student you're part of that team from day one, doing real work on the product, not intern busywork, with room to go deep on compilers and binary security if that's your thing.

Your Impact & Tasks

We have more tasks than hands. Tell us where you'd start.

  • Build internal tooling and automation, mostly in Python and modern C++
  • Extend our testing and CI infrastructure around the compiler
  • Evaluate hardened binaries for correctness, performance, and security impact
  • Integrate our technology into build and deployment workflows
  • Go deeper into compiler internals, if you bring the background

What You Bring

You're deep into a Bachelor's or working on a Master's in computer science, IT security, or a related field.

  • Solid programming skills, ideally in Python or modern C++
  • Curiosity for binaries, compilers, and how systems break
  • Self-organized and reliable, you follow through and ask sharp questions
  • CTFs, reverse engineering, systems security, or related coursework earn bonus points.

What We Offer

  • Get paid to work on compilers, binaries, and exploits while you study
  • Learn directly from a founding team with deep security, compiler, and space-systems pedigree (top-tier security research, DARPA, SpaceX)
  • Your code ends up protecting real fleets across aerospace and defense
  • Fair pay, and hours that flex around lectures and exam season
  • A real shot at a full-time role after graduation

We're looking for builders, hackers, and systems thinkers. If this sounds like you, apply.
