    • Job Zusammenfassung

    In diesem Job entwickelst du Compiler-Technologien, die die Builds gegen Exploits härten, und analysierst dabei generierte Binärdateien. Du arbeitest mit C++ und Python sowie an Integrationen in CI/CD-Systeme.

    Job Technologien

    Deine Rolle im Team

    • As a Compiler Engineer, you'll build and own the compiler technology at the core of Variant's product, turning cutting-edge diversification into something that ships.
    • You'll work across two areas, the compiler itself and the systems and tooling that run it at fleet scale, with real ownership rather than narrow ticket work.
    • You'll have a direct line to the founding team, immediate impact on what customers run, and room to grow from a strong early-career engineer into the owner of a core domain.
    • Develop and extend compiler passes that harden builds against exploitation.
    • Reverse engineer and analyze the generated binaries to validate transformations.
    • Measure security and performance impact across x86, AArch64, and RISC-V targets.
    • Build tooling in modern C++ and Python, and integrate the compiler into CMake and customer CI/CD.

    Unsere Erwartungen an dich

    Ausbildung

    • Master's degree, or equivalent hands-on experience, in cybersecurity or computer science.

    Qualifikationen

    • Familiarity with Python and modern C++.
    • Comfortable reading assembly and debugging low-level code on at least one of x86, AArch64, or RISC-V.
    • Self-organized and self-driven, with strong personal initiative.
    • Prior work on compilers like Clang/LLVM or IR-level transformations.
    • Familiarity with binary analysis tooling such as Ghidra, IDA, or Binary Ninja.
    • Knowledge of exploit mitigations (ASLR, CFI, stack canaries, DEP).
    • Low-level systems background, spanning embedded, firmware, OS internals, or ELF/PE formats, linkers, and loaders.

    Erfahrung

    • Hands-on experience with binaries, whether reverse engineering, exploitation, or vulnerability research.

    Unser Angebot

    • Work on rare, hard problems where compilers meet binary security, the kind most engineers never get to touch.
    • Early-stage equity and competitive compensation on the ground floor.
    • Learn directly from a founding team with deep security, compiler, and space-systems pedigree (top-tier security research, DARPA, SpaceX).
    • See your work protect real fleets across aerospace, defense, and active conflict zones.
    • Based in the Bochum office, with regular collaboration across Germany and the U.S. and the chance to work from or visit the US team.
