Laboratory Technician

Milvus Advanced is redefining materials science by creating rare metal alternatives through modern alchemy.

We replace expensive, scarce elements such as indium, gold, iridium, and platinum with high-performance, earth-abundant nanoalloys and functional materials. Our discovery and scale‑up platform turns deep chemistry into manufacturable products for energy, optoelectronics, and chemical manufacturing.

As critical minerals take centre stage geopolitically, we ask: what happens when key elements are constrained or run out? Instead of merely optimising today’s materials, we pursue transformational substitutions that reduce dependence on fragile supply chains and rare elements by creating new, lab‑made materials that are abundant, affordable, and sustainable.

Our technologies aim to:

• Reduce dependence on rare or critical metals
• Improve device efficiency, stability, and manufacturability
• Enable affordable, scalable next‑generation materials and devices
• Accelerate the clean‑tech transition

We are backed by leading global investors such as Hoxton and Lower Carbon, and are scaling rapidly from lab breakthroughs to real‑world products.

We are seeking a hands‑on, detail‑oriented electrochemical lab technician to join our growing team. You will directly support the development of advanced materials and components for electrolysis. This includes fabricating catalyst‑coated membranes (CCMs), assembling membrane electrode assemblies (MEAs), and optimising electrochemical processes.

This is a high‑impact, practical role in a fast‑paced lab environment, with plenty of room to learn, contribute, and grow.

Location: Oxford

Role: Electrochemical Lab Technician

• Operate and maintain electrochemical equipment (potentiostats, electrochemical cells, electrolyser systems)
• Fabricate catalyst‑coated membranes (CCMs) and substrates (CCSs) for electrolysers
• Assemble MEAs and integrate them into electrolysis systems for performance testing
• Conduct electrochemical tests (e.g. cyclic voltammetry, impedance spectroscopy, chronoamperometry)
• Design and modify experimental setups for electrolysers, fuel cells, and related systems
• Formulate catalyst inks and apply coatings using advanced deposition techniques (spray, slot‑die, decal transfer)
• Analyse test data to optimise performance, efficiency, and durability
• Support the scale‑up of electrochemical processes for commercial deployment
• Maintain a clean and safe laboratory environment, ensuring compliance with safety procedures
• Track and manage lab inventory and consumables
• Calibrate, troubleshoot, and maintain lab equipment to ensure reliable results
• Collaborate with cross‑functional teams and share results to advance broader R&D goals

Applicants must have the right to work in the UK. We are unable to offer visa sponsorship for this role.

• Familiarity with coating techniques (spray, slot‑die, etc.)
• Experience working with electrolyser or fuel cell stacks (a plus)
• Strong problem‑solving skills and a collaborative mindset
• Comfort working in a fast‑paced, multidisciplinary startup environment

• Make an impact:
  Help solve one of the world’s most urgent challenges
• Be part of something big:
  Shape technologies that could redefine global industries
• Join early, grow fast:
  Play a meaningful role in a fast‑scaling, well‑funded company
• World‑class team:
  Work with brilliant, collaborative people who care deeply about the mission
• Backed by the best:
  Supported by top global investors in climate, deep tech, and industrial transformation
• Personal growth:
  Every team member receives a training and development budget
• Your health matters:
  Private health insurance for full‑time employees
