Senior Optoelectronics engineer Location: London (Hybrid)

Salary: £60,000 – £80,000 + Benefits

Visa & Relocation: Support available for qualified candidates

This role would suit en electronics or optical engineer with experience of highspeed fibreoptic network electronics integration, test and validation.

This is an exciting and new opportunity to join a start-up involved with the research, development and design of optical / photonic technologies. Their technologies are designed to radically improve network speed and energy efficiency of AI / ML applications.

This role involves the test, prototyping, characterization and validation of their ultra-fast optical hardware products.

As a Senior Optoelectronics engineer / Senior Electronics Systems Engineer, you’ll take an active, hands-on role in lab-based experimentation, hardware integration, and system-level validation. Working closely with multidisciplinary design teams, you’ll bring together advanced electronics (SoC / high speed boards) and optical technologies, helping to move products from prototype to production readiness.

Typical involvements - Senior Optoelectronics engineer / Hardware Validation Engineer

  • Integrate and test very high-speed optical and electronic hardware systems

  • Assess optical transmission and network performance for short-reach AI Networked Systems

  • Develop and execute test plans for high-speed optical transceivers across the full product lifecycle (prototype, validation, production).

  • Perform electrical and optical characterisation of transceivers, specifically in burst-mode Tx/Rx testing.

  • Analyse test data to identify performance margins, failure modes, and opportunities for design/manufacturing improvements.

  • Optimise receiver performance through equalisation tuning (CTLE, DFE, FFE) and characterise link margins.

  • Design and execute automated test and characterisation routines for prototypes and NPI systems.

  • Analyse and optimise system-level performance across electrical and optical domains.

    Candidates should be collaborative, analytical, and hands-on approach to solving complex engineering challenges

    Skills / Knowledge Required: Senior Optoelectronics engineer/ Hardware Validation Engineer

  • MSc or PhD degree in optical communications, photonics, physics, electronics engineering or other relevant areas

  • Proven experience working in industry on similar high-speed electronics / optical systems (e.g. >50 Ghz : >10Gbps)

  • Strong background in optical / photonic or high-speed electronic system testing, validation, or integration.

  • Understanding of signal integrity, high-speed PCB design considerations, and packaging impacts on performance.

  • Experience with fibre-optic communication systems testing (OLT, ONT, PON) and integration.

  • Expertise in burst-mode transceiver characterisation.

  • Solid understanding of equalisation techniques (CTLE, FFE, DFE) for improving high-speed link performance.

  • Proficiency in using high-speed measurement instruments (e.g., sampling oscilloscopes, BERTs, burst-mode analysers).

  • Familiarity with optical components (lasers, photodiodes, burst-mode APDs/TIAs, modulators) and transceiver architectures.

    Others (beneficial): Senior Optoelectronics engineer

  • Strong hands-on experience in optical / photonic communication systems development and testing, ideally at 100Gbps and above.

  • Experience with automated test systems and scripting (e.g., Python, Matlab, C++, C#).

  • A strong and demonstrable interest in sustainable technologies, AI, ML and / or HPC would be preferred.

    This is a great opportunity to join a highly technical team driving innovation in next-generation AI / ML networking hardware.

    The Senior Optoelectronics engineer / hardware validation engineer opening is based in central London (hybrid). Assistance can be granted to obtain working visas

New Quantum Computing Employers to Watch in 2026: UK and International Companies Advancing Quantum Careers

Quantum computing is no longer confined to research labs. As companies convert quantum theory into testable products, algorithms, and computing platforms, demand for professionals with quantum knowledge — whether physics, algorithms, software development, or hardware engineering — is rising. In 2026, quantum computing organisations are securing significant funding, industry partnerships, and contracts across sectors such as energy, finance, telecommunications, defence, and healthcare. For candidates exploring opportunities on www.QuantumComputingJobs.co.uk , understanding which employers are hiring now and scaling quantum teams is crucial. This article profiles the new and high‑growth quantum computing employers to watch in 2026, with a specific focus on UK‑based innovators, international firms with UK operations, and leading global quantum organisations.

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

Quantum computing is one of the most exciting frontiers in science and technology — and the job market reflects that excitement. But for aspiring practitioners, the sheer number of tools, frameworks, programming languages and hardware platforms can feel overwhelming. One job advert mentions Qiskit, another talks about Cirq or Pennylane. You see references to quantum annealers and superconducting qubits, to measurement hardware and simulators, to noise mitigation libraries and cloud platforms. It’s easy to conclude that unless you master every quantum tool, you’ll never get a job. Here’s the honest truth most quantum computing hiring managers won’t explicitly tell you: 👉 They don’t hire you because you know every tool — they hire you because you can apply the right tools to solve real problems and explain why your solutions work. Tools matter, but context, understanding, judgement and results matter more. So how many quantum computing tools do you actually need to know to succeed in a job search? The real answer is significantly fewer than most people assume — and far more focused by role. This article breaks down what tools really matter in quantum jobs, which ones are core, which are role-specific, and how you can build a coherent toolkit that employers actually value.

What Hiring Managers Look for First in Quantum Computing Job Applications (UK Guide)

Quantum computing is one of the fastest-evolving fields in technology, blending physics, mathematics, computer science and engineering. Roles in this space — from Quantum Algorithm Developer and Quantum Software Engineer to Quantum Research Scientist and Quantum Hardware Specialist — are highly sought after, and hiring managers are exceptionally selective. Because quantum computing is complex and multidisciplinary, recruiters and hiring managers look for clear, concrete evidence of relevant expertise and impact right at the start of your application. They often decide whether to read your CV in detail within the first 10–20 seconds, based on a handful of high-value signals. This guide breaks down exactly what hiring managers look for first in quantum computing applications, how they assess CVs and portfolios, and what you can do to optimise your application to get noticed in the UK quantum job market.
