Staff Embedded Software Engineer

We're looking for a Staff Software Engineer to join the Embedded Software Platform team in Athens, Greece, part of Renesas' Embedded Processing group. You'll contribute in the architecture and development of the platform software - drivers, middleware, and RTOS — that runs on Renesas devices.

Responsibilities

Own the software architecture for embedded platform components — define interfaces, layering, and portability strategy across Renesas device families, and make the build-vs-adopt and design trade-off calls; Lead the technical execution of embedded software projects end to end: break down scope, identify risk early, resolve cross-team dependencies, and keep delivery on track against schedule and quality targets; Provide technical leadership across the team — set coding, review, and testing standards; Design, develop, and maintain platform software hands-on, including low-level drivers, middleware, and RTOS integration; Own the quality of delivered software, from architecture and design review through verification and release; Plan and estimate work for yourself and the project team, manage competing priorities across parallel efforts, and report status and risk to project and engineering leadership; Mentor and grow senior and junior engineers through design review, code review, and direct technical coaching; Work closely with hardware, silicon, applications, and product teams, and represent the team's technical position to internal stakeholders and customers

Requirements

Bachelor's, Master's, or PhD in Electrical/Computer Engineering, Computer Science, or a related field, with 10+ years of embedded software development experience in consumer electronics, automotive, medical, or a similar domain; Proven track record architecting embedded software platforms that shipped in volume, including ownership of designs across multiple product generations; Expert C programming skills and deep experience designing software for deeply embedded, resource-constrained platforms; Deep knowledge of 8/16/32-bit MCU architectures, including ARM Cortex-M, and of the hardware/software boundary: memory maps, interrupt and DMA architecture, clocking, and low-power design; Proficient with CMake and embedded cross-compilation toolchains (GCC, LLVM/Clang, or vendor compilers), and with Docker for reproducible build and test environments; Strong experience with CI/CD and test automation for embedded targets, including hardware-in-the-loop testing; Expert across the full software engineering lifecycle, including verification of deliverables against specifications and requirements; Fluent debugging with lab equipment and tooling: oscilloscopes, logic analyzers, protocol analyzers, multimeters, and JTAG/SWD debuggers; Demonstrated ability to lead technical work across a team — driving decisions to closure, aligning stakeholders, and delivering to committed dates; Excellent written and verbal communication skills, including the ability to explain technical trade-offs to non-specialist and customer audiences

Nice to have

Multiple RTOS and OS environments — Zephyr, FreeRTOS, embedded Linux — and experience porting or abstracting across them; Renesas FSP (Flexible Software Package) or comparable vendor HAL/driver frameworks; Hard real-time and safety-critical software design — schedulability, latency and jitter analysis, deterministic behavior under load; Security architecture: secure boot, key storage, ARM TrustZone, cryptographic accelerators; Connectivity protocols e.g. Bluetooth Low Energy stacks; Sustained contributions to open-source projects, ideally as a maintainer or reviewer; AI-assisted development experience: coding agents, agentic workflows, MCP
