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 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.\nWe 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.\nThe 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.\nResponsibilities\nThe 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.\nLead or contribute to FPGA architectural definition, detailed design and implementation activities using VHDL.\nDevelop requirement-based FPGA designs, ensuring traceability from system and hardware requirements through to FPGA low-level requirements, design artefacts and verification evidence.\nProduce and maintain FPGA design documentation, including design descriptions, interface definitions, implementation notes and review evidence.\nSupport DO-254 planning, requirements capture, design, review and verification activities for complex electronic hardware.\nWork closely with systems, safety, electronics, software, test and certification engineers to ensure FPGA designs are correctly integrated within the wider product architecture.\nSupport the development and maintenance of FPGA development workflows, including configuration management, branch-based development, pull requests, design reviews and formal release baselines.\nContribute to FPGA implementation activities including synthesis, constraints, timing closure, build scripting and implementation tool flow management.\nSupport verification engineers in developing requirement-based verification strategies, test plans, simulation environments and coverage closure.\nParticipate in code and documentation reviews, including independent review of VHDL design code and review of evidence generated by linting, simulation and implementation tools.\nHelp maintain and improve Stirling Dynamics’ FPGA development processes, toolchains and engineering practices.\nProvide technical leadership, mentoring and guidance to less experienced engineers.\nThe level and scope of responsibilities will be dependent on the successful candidate’s knowledge and experience.\nQualifications\nCandidates 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.\nEssential skills\nStrong VHDL design capability, including requirements-based RTL design and development of maintainable, reviewable FPGA code.\nPractical understanding of DO-254 processes and the artefacts required to support FPGA or complex electronic hardware development.\nAbility to work effectively with electronics hardware engineers, systems engineers, software engineers and verification engineers.\nAbility to work with incomplete or evolving requirements and apply sound engineering judgement to progress practical design solutions.\nStrong written communication skills and the ability to produce clear design documentation, review records and engineering rationale.\nExperience\nSignificant experience of FPGA design and development for complex digital systems.\nExperience of FPGA development for high-integrity, safety-critical or mission-critical applications.\nExperience of developing FPGA designs from system or hardware requirements, including requirement decomposition, derived requirements and traceability, with the use of tools such as such as Siemens Polarion or DOORS.\nExperience with FPGA simulation and debug using tools such as QuestaSim or ModelSim.\nExperience with FPGA implementation toolchains such as Xilinx Vivado, Intel Quartus or equivalent vendor tools.\nExperience conducting code reviews and documentation reviews within a controlled development process.\nExperience using configuration management and source control tools, for example Git, Azure DevOps, Bitbucket or similar.\nExperience working on DO-254 development projects, particularly DAL A, DAL B or DAL C airborne electronic hardware.\nExperience of requirements-based FPGA verification using SystemVerilog, UVM or a similar structured verification methodology.\nExperience defining FPGA verification strategies, test plans, coverage objectives and verification evidence.\nExperience using linting tools and applying coding rule sets suitable for DO-254 or high-integrity FPGA development.\nExperience with formal verification, code coverage, functional coverage or coverage closure activities.\nExperience creating or maintaining automated build, simulation or regression test workflows.\nScripting experience using Python, Tcl, shell scripting or similar for FPGA build, simulation, automation or toolchain control.\nExperience with HIL, SIL or test-rig environments used to support electronic hardware or FPGA verification.\nExperience integrating FPGA designs with processors, ADCs, DACs, motor control electronics, communications interfaces or other mixed hardware/software systems.\nExperience with aerospace communication interfaces, control systems, electromechanical actuators or airborne electronic hardware.\nExperience mentoring engineers or providing technical leadership within a small or multi-disciplinary team.\nExperience gained in a large aerospace, defence or avionics organisation, with an interest in applying that knowledge in a more agile and hands-on engineering environment.\nBenefits\nCompetitive Package - Grade 7 with a salary banding of £57,500 - £72,500\nWe offer a range of benefits to our employees to recognise their efforts.
