Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale.

We are seeking a Hardware Electronics Design Engineer to design, develop, and validate high-speed and high-power electronic systems. This role involves schematic design, PCB development, signal and power integrity, and hands-on bring-up of complex hardware. The engineer will work closely with system, mechanical, firmware, and manufacturing teams to deliver reliable, high-performance products from concept through production.

The ideal candidate has deep experience with high-speed interfaces and power delivery, and is comfortable owning designs through debugging, validation, and manufacturing release.

Key Responsibilities

  • Design and develop high-speed (PCIe/Ethernet) electronic circuits and systems
  • Design power delivery networks (PDN) including DC-DC converters, multi-phase VRMs, and protection circuits
  • Create schematics, BOMs, and design documentation for complex PCBs
  • Lead board-level architecture decisions including power topology, interface selection, and component choice
  • Work with PCB layout engineers to ensure proper stack-ups, routing, and return paths
  • Address thermal considerations in collaboration with mechanical and thermal teams
  • Lead board bring-up, debug, and root-cause analysis of hardware issues
  • Use lab equipment (oscilloscopes, network analysers, power analysers) to validate performance
  • Support compliance, reliability, and environmental testing
  • Support DFM/DFT reviews and transition designs into manufacturing

Qualifications & Experience

  • Diploma, Bachelor’s or Master’s degree in Electrical or Electronic Engineering, or equivalent experience
  • 7+ years of experience in hardware electronics design
  • Proven experience designing high-speed digital and high-power circuits
  • Experience taking designs from concept through production

Technical Skills

  • High-speed digital design (DDR, PCIe, Ethernet, SerDes)
  • Power electronics and PDN design (buck/boost converters, VRMs, protection)
  • Signal integrity (SI) and power integrity (PI) principles
  • Schematic capture and PCB tools (Xpedition, Altium, Cadence, or equivalent)
  • Hardware debug and lab instrumentation

Preferred Experience (Nice to Have)

  • Experience with multi-layer high-speed PCBs (10+ layers)
  • Familiarity with SI/PI simulation tools
  • Experience with compliance testing (EMI/EMC, safety)
  • Experience with AI accelerator or HPC hardware
  • Thermal Management: Knowledge of techniques to manage heat dissipation in high-power systems

How we work

  • Ownership and execution: you will have full agency to drive your work forward
  • Rapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines
  • Full-stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact
  • Optimistic and pragmatic: we possess the will to win, and to do the hard work to get us there
  • Team player mentality: the mission is bigger than any of us, and we have the curiosity and technical focus to see the best idea shipped, no matter who’s it is

About us

  • Founded in 2022, team of 70+ which is expanding rapidly
  • Modern, open offices in London and Bristol
  • Collaborative, problem-solving culture built on deep curiosity, entrepreneurial initiative and technical fluency

Export control and security clearance

Certain roles may involve working on technologies subject to export restrictions. Applicants may be required to undergo additional eligibility checks to ensure compliance with applicable law.

Where to Advertise Semiconductor Jobs in the UK (2026 Guide)

Advertising semiconductor jobs in the UK requires a fundamentally different approach to most technical hiring. The candidate pool is one of the smallest and most specialised in any engineering discipline — spanning IC design engineers, process engineers, fab technicians, EDA tool developers, compound semiconductor physicists and power electronics specialists. General job boards are largely ineffective for semiconductor hiring. The community is tight-knit, highly academic in its roots and concentrated around a small number of university groups, fab facilities and design centres. Specialist boards, academic channels and direct community engagement are the primary sourcing strategies that work. This guide, published by SemiconductorJobs.co.uk, covers where to advertise semiconductor roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Semiconductor Jobs UK 2026: What to Expect Over the Next 3 Years

Semiconductors are the foundational technology of the modern world. Every smartphone, electric vehicle, data centre, medical device, satellite, and AI accelerator depends on them. And yet for much of the past decade, the strategic importance of semiconductor design and manufacturing was something that governments, investors, and employers took largely for granted — until supply chain crises, geopolitical tensions, and the insatiable compute demands of artificial intelligence made the vulnerability of global semiconductor supply chains impossible to ignore. The response has been significant and sustained. The UK's National Semiconductor Strategy, the US CHIPS Act, the EU Chips Act, and parallel investment programmes across Japan, South Korea, and Taiwan have collectively committed hundreds of billions of pounds to semiconductor research, design, and manufacturing capability. In the UK specifically, that investment is beginning to translate into real hiring — across compound semiconductor manufacturing, chip design, semiconductor equipment, advanced packaging, and the growing ecosystem of fabless design companies that are choosing Britain as their base. For job seekers, the semiconductor jobs market of 2026 represents an opportunity that is more commercially urgent, more geographically distributed, and more technically diverse than at any previous point in the sector's UK history. The roles being created span the full semiconductor value chain — from fundamental materials research and process engineering through chip design, verification, and the software that makes silicon useful. The candidates who will thrive over the next three years are those who understand where that value chain is being built, which technical areas are attracting the most investment, and how to position their skills at the intersection of the sector's greatest needs. This article breaks down what the UK semiconductor jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career at the leading edge of one of the most strategically important technology sectors in the UK economy.

New Semiconductor Employers to Watch in 2026: UK and International Companies Transforming Chip Careers
