Fractile’s mission is to enable a new chapter in the AI revolution. We’re pioneering AI innovation where hardware and software join to create something extraordinary, unlocking the power of the world’s largest language models with speed increases of x100. Our team is rapidly expanding, and we're searching for visionary engineers, scientists, and thinkers who share our passion for pushing boundaries and redefining what's possible. If you're ready to join a dynamic group of innovators shaping AI's future, we want to hear from you!

We are seeking a highly skilled Senior/Principal Physical Design Engineer to contribute to our next-generation chip designs. As a Physical Design Engineer, you will be responsible for the end-to-end implementation of complex IC physical designs, from synthesis to sign-off. You will collaborate with cross-functional teams, including logic design, verification, and process technology, to optimise performance, power, and area (PPA) while ensuring design integrity and manufacturability.

Key Responsibilities:

  • Drive the physical implementation of ASIC/SoC designs, including floorplanning, placement, clock tree synthesis (CTS), routing, and sign-off.
  • Work on synthesis, timing analysis (STA), and optimisation to achieve the best PPA metrics.
  • Perform power planning and analysis, addressing IR drop, electromigration, and low-power design techniques.
  • Ensure design rule check (DRC), layout vs. schematic (LVS), and other physical verification compliance.
  • Collaborate with DFT engineers to integrate design-for-test (DFT) structures into the physical implementation.
  • Develop flows in EDA tools such as Cadence Innovus, Synopsys ICC2, Mentor Graphics Calibre, and others.
  • Interface with foundries and process engineers to ensure manufacturability and yield optimisation.
  • Work closely with RTL and architecture teams to drive design feasibility, constraints, and physical-aware RTL design.

Preferred Qualifications:

  • Bachelor’ Master’s or PhD in Electrical Engineering, Computer Engineering, or a related field.
  • 7+ years of experience in physical design for advanced technology nodes (e.g., 7nm, 5nm, or below).
  • Strong proficiency in EDA tools for place & route, STA, and sign-off.
  • Solid understanding of CMOS technology, semiconductor physics, and process limitations.
  • Experience with low-power design methodologies, power optimisation techniques, and multi-power domain architectures.
  • Expertise in timing closure, signal integrity, IR drop analysis, and formal verification.
  • Proficiency in scripting languages like TCL, Perl, or Python for automation.
  • Excellent problem-solving skills, communication, and teamwork in a collaborative design environment.
  • Experience in high-performance computing (HPC), AI accelerators, or networking chips.

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.

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

The semiconductor industry is entering a new era of investment, geopolitical significance, and technological innovation. As advanced chips power everything from artificial intelligence and edge computing to autonomous vehicles and 5G infrastructure, demand for skilled professionals across design, verification, fabrication, and test engineering continues to rise. For professionals exploring opportunities on www.SemiconductorJobs.co.uk , understanding which employers are scaling, raising funds, winning contracts, or establishing UK operations is critical. This article highlights the new semiconductor employers to watch in 2026, including UK innovators, major international players expanding locally, and emerging firms driving next‑generation semiconductor technologies.

How Many Semiconductor Tools Do You Need to Know to Get a Semiconductor Job?

If you’re pursuing a career in the semiconductor industry, it can feel like you’re expected to master an endless list of tools, software packages and lab equipment before you even submit a CV. One job advert wants experience with TCAD and process simulation, another mentions SPICE and yield tools, while yet another asks for test automation platforms, yield analysis software, hardware description languages, EDA suites and hundreds of others. With so many technical names thrown around, it’s easy to fall into “tool anxiety” — the feeling that you’re behind because you don’t know every piece of software, every lab instrument and every process control suite. Here’s the honest truth most semiconductor hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool — they hire you because you can use the right tools to solve real engineering problems and explain your reasoning clearly. Tools matter, absolutely. But they exist to help you deliver measurable results — not to be collected like badges. So how many semiconductor tools do you actually need to know to get a job? The answer is a lot fewer than you might think — and far more focused on core capabilities than a long checklist. This guide breaks down what employers really value, which tools are essential, which are role-specific, and how to focus your learning so you are confident and credible.
