About this role
Sonatus is transforming automotive software by bringing mobile-industry-style agility to vehicles—rapid feature evolution, seamless updates, continuous improvement. With their technology already running on over 9 million vehicles globally, they're looking for a Software Developer to join their Vehicle Applications team in Dublin and help build the next generation of edge computing applications that power connected, software-defined vehicles.
You'll spend your time writing clean, high-performance C++ code for data applications that run directly on vehicle hardware, collaborating with other developers, QA, and customer engineering teams to deliver robust solutions. The work spans the full development lifecycle: designing systems, implementing with rigorous testing, debugging complex issues, and documenting for both internal and external stakeholders. This role demands strong fundamentals in modern C++, Linux development, and concurrent programming, plus practical experience shipping production software. Python and shell scripting for automation, familiarity with build systems like CMake or Bazel, and solid grasp of operating systems and algorithms round out the core skill set.
If you have 3+ years building production systems and want to apply deep technical skills to real automotive challenges, this is a chance to work on genuinely complex problems at scale. Automotive experience—particularly with Linux, CAN/Ethernet protocols, or edge computing—is a plus but not required. Sonatus offers competitive compensation with stock options, standard benefits including healthcare and pension, and the day-to-day environment of a well-funded, fast-moving company with genuine global reach.
