Hamburg, Hamburg, Deutschland Systola Vollzeit 100.000 € - 150.000 € pro Jahr


Systola GmbH is expanding the core team behind
SystoLOCK
, our passwordless multifactor authentication platform. We're looking for a
Senior Software Developer
who understands Windows at a deep level and enjoys solving hard identity-security problems in elegant ways.

What You'll Work On

You will design and build
native and managed Windows applications and services
that form the backbone of SystoLOCK. This includes secure desktop components, system-level integrations, and high-performance server modules that interact closely with Windows internals.

What You Bring

  • Expert-level knowledge of Windows system architecture
    (Win32 APIs, security subsystems, identity stack)
  • Strong experience in both
    C++ and
    in
    C#/.NET
  • Solid understanding of
    cryptography
    , especially
    Windows crypto implementations
    (CNG, DPAPI, smartcard/PCSC, certificate handling)
  • Ability to work on complex features independently and drive them from concept to stable production code
  • Curiosity, creativity, and a willingness to challenge old assumptions

Nice to Have

  • Experience with authentication technologies, identity protocols, SAML, FIDO, smart cards, secure design
  • Background in building system-level security products or middleware
  • Familiarity with cryptographic key management, or hardware-backed cryptography

How We Work

We are an
unusually independent, highly technical team
. We value clear thinking, clean code, and people who build things that last. You will have broad autonomy, minimal bureaucracy, and direct influence on the product architecture.

  • Preferred:
    on-site in Germany (Hamburg area)
  • Possible:
    hybrid or remote for exceptional candidates
  • No formal degree required
    : only skill, ownership, and the ability to deliver.

Why SystoLOCK?

  • Because we are redefining authentication: removing passwords, unifying token types, and building a new foundation for enterprise identity. You will be shaping the platform that CIOs, CISOs, and engineers trust for critical access control. Get familiar with SystoLOCK
