As a Senior Embedded Software Engineer you will design, develop, verify and maintain the safety-related firmware at the heart of our Vehicle Control Platform.
This is a hands-on engineering role; you will own microcontroller code from design through implementation, meeting formal requirements while optimising system performance.
You will join a senior, multi-disciplinary platform team and work day -to -day alongside hardware and electrical engineers, system architects, functional safety engineers, application software teams and product management.

Firmware Design and Implementation

• Design, implement, debug and maintain embedded C (and C++ where appropriate) firmware for safetyrelated vehicle control ECUs, from requirement through to released, verified software.
• Implement and maintain vehicle communication interfaces — CAN 2.0A/B, J1939 and other higher-layer CAN protocols, and serial links — against formally controlled interface specifications.
• Develop I/O and actuation software: digital and analogue inputs, PWM and proportional outputs, sensor signal conditioning, scaling, calibration and plausibility checking.
• Implement diagnostics, fault detection and fail-safe behaviour: watchdogs and monitors, fault classification, and transitions into clearly defined safe states.
• Contribute to migrating and modernising an existing production firmware platform onto current hardware.

Safety, Quality and Traceability

• Develop against decomposed, traceable requirements and maintain bidirectional traceability from requirement to design, code and verification evidence.
• Author and maintain design documentation, interface specifications and verification records.
• Perform and participate in rigorous peer design and code reviews, and help raise the team’s engineering standards.

Verification, Tooling and Automation

• Build and maintain automated test capability: embedded unit and integration tests, and hardware-inthe-loop test rigs.
• Extend continuous integration and delivery pipelines for embedded builds, static analysis, automated test execution, versioning and release artefact packaging.
• Work with Linux-based coprocessors and services used for data logging, connectivity, remote diagnostics and observability.
• Support bench, vehicle and field commissioning; investigate and root-cause issues found in integration testing.

• Bachelor’s or Master’s degree in Electrical or Electronic Engineering, Computer Engineering, Mechatronics, Computer Science or a closely related discipline; or equivalent demonstrable experience.
• 10+ years of professional embedded software development, including at least two (2) years delivering production firmware on 32-bit microcontrollers.
• Embedded C: Expert-level embedded C, with working proficiency in C++. Deep comfort with fixed-point and bounded-resource programming, and with codebases where dynamic memory allocation is prohibited.
• Real-time software: Bare-metal and/or RTOS development — interrupt handling and priority design, scheduling, cyclic task structure, timing and latency analysis, and multicore considerations.
• Hardware fluency: Able to read hardware schematics, MCU datasheets and reference manuals and derive correct peripheral, driver and I/O configuration from them.
• Vehicle networks: Hands-on CAN experience — CAN 2.0A/B plus J1939 or a comparable higher-layer protocol; defining and maintaining message sets and signal databases; bus analysis and fault-finding with standard CAN tooling.
• On-target debugging: Practical use of debug probes, oscilloscopes, logic analysers and bus loggers to diagnose faults on real hardware.
• Coding standards: Experience developing to an enforced coding standard such as MISRA, with static analysis in the development loop.
• Development environment: Comfortable in Linux development environments, with Git-based workflows, code review culture and CI/CD pipelines.
• Experience with TCP/IP networking and embedded Linux device-to-cloud connectivity on Arm-based processors.

• Multicore automotive-grade microcontroller families, and commercial safety-certified ECU platforms supplied with a vendor BIOS/HAL and configuration tooling.
• Containerised build environments and self-hosted CI runners for embedded builds and automated hardware test.
• Custom embedded Linux distribution builds with the Yocto or Buildroot — BSP and layer maintenance, kernel and device-tree configuration.
• Requirements management tooling, and Jira / Confluence or equivalent.
• Requirements discipline: Experience working to formal, traceable requirements and interface control documents.
• Scripting and automation: Python and shell scripting for test automation, tooling and data analysis.

• 10% or less travel
