Overview
Stirling Dynamics is recruiting a Principal FPGA Design and Development Engineer to join the Software & Electronic Hardware team.
Are you ready to take ownership of FPGA design for high-integrity aerospace products?
Due to recent contract wins, continued growth, and the need to strengthen capability within our Software & Electronic Hardware team, Stirling Dynamics is looking for a talented and experienced Principal FPGA Design and Development Engineer to join our team delivering FPGA-based solutions for safety-critical and high-integrity aerospace systems. This role is intended for an engineer with strong hands-on FPGA design experience who can contribute across the full development lifecycle, from requirements capture and architectural definition through to detailed VHDL design, implementation, review, verification support, integration, and certification evidence. The successful candidate will support the development of gateware for electro-mechanical systems and airborne electronic hardware, including products developed within a DO-254 framework.
We are looking for someone who enjoys technical ownership and practical engineering delivery. The right person will bring the discipline and rigour expected from safety-critical FPGA development, while also being comfortable working in a dynamic, multi-disciplinary environment where processes are continuously being optimised, and Principal engineers are expected to help shape the way we work. This would suit someone who has gained strong experience and is looking for a broad, and influential role in a smaller and more agile engineering business.
The role is based in our Bristol office with occasional travel to our clients’ sites as required, however, as part of our commitment to flexible working, employees can work a hybrid working model.
Responsibilities
The successful candidate will join a team responsible for the design, implementation, and verification support of FPGA solutions for safety-critical and high-integrity aerospace systems.
- Lead or contribute to FPGA architectural definition, detailed design, and implementation activities using VHDL.
- Develop requirement-based FPGA designs, ensuring traceability from system and hardware requirements through to FPGA low-level requirements, design artefacts, and verification evidence.
- Produce and maintain FPGA design documentation, including design descriptions, interface definitions, implementation notes, and review evidence.
- Support DO-254 planning, requirements capture, design, review, and verification activities for complex electronic hardware.
- Work closely with systems, safety, electronics, software, test, and certification engineers to ensure FPGA designs are correctly integrated within the wider product architecture.
- Support the development and maintenance of FPGA development workflows, including configuration management, branch-based development, pull requests, design reviews, and formal release baselines.
- Contribute to FPGA implementation activities including synthesis, constraints, timing closure, build scripting, and implementation tool flow management.
- Support verification engineers in developing requirement-based verification strategies, test plans, simulation environments, and coverage closure.
- Participate in code and documentation reviews, including independent review of VHDL design code and review of evidence generated by linting, simulation, and implementation tools.
- Help maintain and improve Stirling Dynamics’ FPGA development processes, toolchains, and engineering practices.
- Provide technical leadership, mentoring, and guidance to less experienced engineers.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The level and scope of responsibilities will be dependent on the successful candidate’s knowledge and experience.
Qualifications
Candidates will ideally be degree qualified in Electronic Engineering, Electrical and Electronic Engineering, Computer Engineering, or a similar relevant discipline. Equivalent industrial experience in FPGA, ASIC, firmware, or airborne electronic hardware development will also be considered. Chartered Engineer status, or working towards professional registration, would be advantageous.
Essential skills
Skills and experience should include most of the following:
- Significant experience of FPGA design and development for complex digital systems.
- Strong VHDL design capability, including requirements-based RTL design and development of maintainable, reviewable FPGA code.
- Experience of FPGA development for high-integrity, safety-critical, or mission-critical applications.
- Practical understanding of DO-254 processes and the artefacts required to support FPGA or complex electronic hardware development.
- Experience of developing FPGA designs from system or hardware requirements, including requirement decomposition, derived requirements, and traceability, with the use of tools such as Siemens Polarion or DOORS.
- Experience with FPGA simulation and debug using tools such as QuestaSim or ModelSim.
- Experience with FPGA implementation toolchains such as Xilinx Vivado, Intel Quartus, or equivalent vendor tools.
- Experience conducting code reviews and documentation reviews within a controlled development process.
- Experience using configuration management and source control tools, for example, Git, Azure DevOps, Bitbucket, or similar.
- Ability to work effectively with electronics hardware engineers, systems engineers, software engineers, and verification engineers.
- Ability to work with incomplete or evolving requirements and apply sound engineering judgment to progress practical design solutions.
- Strong written communication skills and the ability to produce clear design documentation, review records, and engineering rationale.
