Senior Embedded Software Engineer

H Squared Talent; Fleet; Sur place; GBP 70 000 - 90 000; Plein temps

Résumé du poste

H Squared Talent is seeking a Senior Embedded Software Engineer (firmware, real-time control and hardware integration) for a growing UK manufacturer of high-precision test instrumentation. You will lead firmware projects from concept to production, primarily in C and C++, while collaborating with electronics engineers on hardware interfaces to ensure precise test results.

The role blends new development with in-depth work on existing code, offering ownership from day one.

Qualifications

• RTOS firmware development experience on microcontrollers or embedded processors (C/C++).
• Proven track record leading firmware from scratch to release or major fixes.
• Hands-on hardware experience: reading schematics, using oscilloscopes and debuggers.
• Familiarity with embedded protocols.
• Clear communication across firmware and non‑firmware colleagues.

Responsabilités

• Lead firmware projects from specification through production in C/C++.
• Analyse existing firmware and identify changes to improve robustness and security.
• Write real-time code for microcontrollers interfacing with sensors and actuators.
• Define hardware/firmware interfaces with electronics engineers.
• Contribute to code reviews, documentation and best practices.
• Assist production and support teams in diagnosing firmware issues.

Description du poste

• Broad technical exposure across microcontrollers, sensors, actuators, control and communications
• A supportive, collaborative engineering culture

We're recruiting a Senior Embedded Software Engineer (firmware, real-time control and hardware integration) for a growing UK manufacturer of high-precision test instrumentation. Their systems combine precision electronics, mechanical actuation and closed-loop control, and the firmware you write directly affects the accuracy of tests that inform real engineering decisions.

Engineering is in a strong growth phase: the team has delivered new products, put solid development processes in place, and now has a full roadmap: refurbishing flagship products, developing next-generation instruments, and expanding into new markets with very different control requirements. You'll help lead a programme of six to eight projects over the next year: reviewing existing firmware and hardware, fixing and hardening what's there, and designing new firmware where platforms need to change. It's a blend of new development and in-depth work on existing code, with ownership from day one.

You're proactive and take initiative rather than waiting to be told what to do. You see the bigger picture, find practical solutions, and keep a sense of humour. The team moves quickly, values a fail-fast approach to learning, and is tight-knit, so you'll enjoy working collaboratively.

What you'll be doing

• Leading and delivering firmware projects from specification through to production, mainly in C and C++
• Analysing existing firmware, identifying what needs to change, and making it robust, secure and compliant
• Writing real-time code for microcontrollers and processors that interface with sensors and actuators
• Working with electronics engineers to define hardware/firmware interfaces at design stage
• Contributing to code reviews, documentation and good embedded development practice across the team
• Helping production and technical support teams diagnose firmware issues on the bench or in the field

The Candidate: Embedded Software Engineer / Firmware Engineer

The ideal candidate will have the following:

• Experience with RTOS firmware development in C or C++ for microcontrollers or embedded processors.
• A track record of leading firmware development, including taking projects from scratch to release, and reworking or fixing existing firmware
• Hands-on hardware experience: reading schematics, using oscilloscopes and debuggers
• Familiarity with embedded protocols
• Clear communication, including explaining technical decisions to colleagues outside firmware
