If you can demonstrate a solid understanding of hardware systems and a practical, problem-solving mindset, we want to hear from you. The Senior Hardware Engineer (will consider applications from a Senior level candidate with 10+ years of relevant experience in designing hardware) will be able to make their mark on a broad and varied range of product designs and will be expected to assist in the integration of these designs into products, being the focal point for the complete system. We are looking for a Principal Hardware Engineer with deep expertise in Power Electronics who is motivated by technically challenging designs and the opportunity to influence product direction. This is a senior, hands-on technical leadership role, ideal for an experienced engineer seeking to shape architectures, mentor others, and see designs through from concept to production., We welcome applications from engineers who can demonstrate strength in most of the following areas - not necessarily every item: * Applying a systems engineering approach across the full product lifecycle * Significant experience in power electronics design, including a range of topologies * Proven ability to take designs from prototype through to production * Experience designing custom or semi-custom magnetic components * Strong understanding of embedded digital electronics, including microprocessors * Practical experience with schematic capture, PCB design, and verification * Ability to analyse problems using SPICE-based and Simulink simulation tools, make sound engineering decisions, and communicate outcomes clearly * Confidence working independently, while also mentoring and supporting others * Comfortable operating in a changing environment with competing priorities * Eligible for, or able to obtain, SC security clearance Desirable Experience: * The following experience would be advantageous but is not essential: * Experience with ADC/DAC, memory devices (SRAM, Flash), and mixed-signal design. * Compliance of products to defence engineering standards (DEF-STAN, MIL-STD etc). * Design for, and compliance to, European Directives [Low Voltage Directive, Electromagnetic Compatibility Directive etc.] * Product design for Manufacture, Assembly and Test. * Product design for environmental requirements (shock, vibration, EMC, etc.) * Familiarity with Mentor Xpedition, * Experience developing DO-254 compliant electronic systems * Experience with FPGAs, SoCs, and high-speed digital interfaces ## Description You will act as the technical focal point for complex electronic systems, leading and supporting multi-disciplinary teams across internal and customer-funded programmes. Your work will span early concept studies, detailed design, verification, and successful integration into production hardware., * As a Principal Hardware Engineer, you will: * Provide technical leadership within a multi-disciplinary design team * Lead the design and development of power electronic systems, from concept through qualification * Lead by example with respect to Safety and Quality, embracing internal and external processes. * Solve complex technical problems on both new developments and existing products * Capture, interpret, and derive customer requirements into clearly bounded design specifications * Produce high-quality schematics, simulations, PCB designs, and support component selection, evaluation, and verification * Direct design reviews, commissioning, debug, fault diagnosis, and lifecycle support * Design to cost and schedule, working effectively within approved budgets * Ensure designs meet relevant industry, customer, and regulatory standards * Support configuration control and managed design change * Produce clear, concise technical documentation and reports * Act as a technical authority in customer discussions within your area of expertise * Maintain a strong hands-on laboratory presence, assembling, testing, and troubleshooting hardware when required ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Breaking the Hardware Mindset: Overcoming Barriers to System-Level Innovation](https://www.wearedevelopers.com/videos/1635-breaking-the-hardware-mindset-overcoming-barriers-to-system-level-innovation) - [Why Your Best Mediors Never Become Seniors (And How to Fix It)](https://www.wearedevelopers.com/videos/2108-why-your-best-mediors-never-become-seniors-and-how-to-fix-it) ## Related Articles - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
