You will own software from requirements to a verified release on real hardware: production C/C++ on microcontrollers, integration into AUTOSAR-based platforms, and delivery inside a functional-safety process. You will work embedded in the client team, with Vynatix behind you. What you will do

• Design, implement and maintain embedded software in C and C++ for automotive ECUs, bare-metal and RTOS-based
• Develop and integrate low-level drivers, communication stacks (CAN, LIN, Automotive Ethernet) and diagnostics (UDS)
• Work within AUTOSAR Classic or similar platforms: configuration, integration and application software
• Contribute to functional-safety work under ISO 26262: requirements, safety analyses, unit and integration testing
• Debug on target hardware with debuggers, oscilloscopes, logic analysers and HIL rigs
• Own quality: code reviews, static analysis (MISRA C), CI pipelines and test automation
• Work closely with hardware, systems and test engineers and with the client's product owners

What we are looking for

• Minimum 7 years of professional embedded software development, most of it in C (C++ is a plus)
• Hands-on experience with 32-bit microcontrollers (ARM Cortex-M/R, Infineon AURIX, NXP S32 or similar)
• Experience with automotive communication protocols (CAN, LIN, Ethernet) and diagnostics (UDS)
• Experience with AUTOSAR Classic or another automotive software platform
• Working knowledge of ISO 26262 and safety-critical development practices (MISRA, requirements traceability)
• Comfortable with Git, CI, unit-test frameworks and debugging on target
• Professional working proficiency in English
• Based in Gothenburg, or ready to relocate (we support relocation)

Nice to have

• Experience with safety-critical products such as restraint systems, ADAS, braking or steering
• Model-based development (MATLAB/Simulink, TargetLink)
• Embedded Linux, Rust, or Python for tooling and test automation
• Cybersecurity for vehicles (ISO/SAE 21434)
• Swedish

What we offer

• Permanent employment with assignments measured in years, not months
• A small company where the founders answer their own messages
• Competitive salary and Swedish-standard benefits, including a benefit bike
• Relocation support if you are moving to Sweden
