Embedded Firmware Engineer

Help shape the next generation of intelligent LED cabin lighting for commercial aviation. This is a hands-on role building robust, real-time embedded software from the ground up, from architecture and algorithms through to implementation, verification, and delivery for safety-critical use.

What you'll do 🛠️

Own the architecture & design: Define software structure, interfaces, and interactions with hardware and other systems; produce design docs and lead peer reviews.
Build from first principles: Develop bare‑metal/RTOS firmware in C for microcontrollers and programmable logic devices.
Low-level development: Write drivers and real-time control software; interface with peripherals (e.g., temperature sensors, I²C, SPI, UART, CAN).
Platform fundamentals: Develop and maintain bootloaders, secure update mechanisms, and modular, object‑oriented components where appropriate.
Hands-on debug: Triage HW/SW interactions using oscilloscopes, logic/protocol analysers; comfortable doing fine soldering/rework as needed.
Verification & documentation: Deliver fully documented designs, implementation plans, and contribute across unit, integration, and system testing.
Technical leadership: Mentor a graduate software engineer and set engineering standards within the team.

What you'll bring 🧠

Essential ✅

Significant experience (ideally 10-15 years) in embedded software/firmware for real-time or bare‑metal systems.
Expert-level C for low-level embedded development; strong microprocessor/microcontroller architecture knowledge.
Proven delivery of drivers, peripheral bring-up, and hardware integration.
Lab confidence: oscilloscopes, logic/protocol analysers; comfortable with board-level investigation and occasional soldering.
Version control (Git) and Agile practices.
Clear, methodical documentation and the ability to own solutions end‑to‑end.
Strong communication and the autonomy to hit the ground running.Desirable ⭐

Safety-critical/high‑integrity experience (e.g. DO‑178C, ISO 26262, IEC 61508).
FPGA or other low-level hardware programming exposure.
CI/CD and automated test familiarity.

Working arrangement 🧭

Onboarding: Expect to be on-site 4 days/week for the first 2-3 months to immerse in the lab, hardware, and product context.
Thereafter: Hybrid pattern of 3 days a week with ongoing lab collaboration as projects require.
