Graduate Software Engineer in Sheffield

Fyous is a Sheffield-based deep-tech company rewriting the rules of manufacturing. Our PolyMorphic Moulding technology uses tens of thousands of digitally controlled pins to form a mould in minutes, thermoform a part directly over it, and reconfigure into the next shape. No resin. No waste. No single-use tooling.

Our Culture at Fyous is anchored in three values: Have Integrity, Innovate, and Inspire. In practice; own your outcomes without excuses, challenge assumptions before they become bad decisions, and constantly raise the bar — for yourself, your teammates, and the market. We move fast, we speak plainly, and we expect the same from everyone regardless of experience level. We invest in growing our team personally as well as technically — through a curated library, regular feedback in the spirit of Radical Candor, and a belief that environment and opportunity shape excellence as much as ability does. What matters to us is how you think.

The Role involves working on Pinpoint — the computational brain of Ghost, our dental machine. It takes a patient's STL dental scan and works out exactly how ~20,000 individually addressable 0.3mm pins should configure themselves to form the mould — then validates that the result will actually thermoform a clinically acceptable aligner before a single pin moves. You’ll join as a software hire, working directly with our Senior Software Engineer who owns Pinpoint end-to-end. They'll mentor you on computational geometry, and the trade-offs involved in shipping software that drives a physical machine in a medical context. From day one you’ll own meaningful pieces of the pipeline and ship code that ends up driving a real machine forming a real aligner that a real patient will wear.

One Non-Negotiable: You Build With AI. If you are not actively building with AI — Claude Code, Cursor, Codex, whatever the bleeding edge looks like the week you read this — you are not our candidate. We want someone who treats these tools as a force multiplier, has opinions about using them well, and is already more productive because of them.

What We Need From You:

• A degree in Computer Science, Mathematics, Physics, Engineering, or a closely related discipline — 2:1 or expected to graduate with 2:1 in 2026, or equivalent industry experience.
• Strong fundamentals in a systems language — ideally C++ or Rust, but a strong C, C#, or modern C++-adjacent background plus demonstrable appetite to go deeper is fine.
• Right to work in the UK.

Role Fit (you'll thrive here if you…)

• Work well in small teams where you enjoy being accountable for outcomes, not just tasks.
• Thrive in fast moving environments where priorities shift and execution matters more than process.
• Communicate clearly in writing and in person.
• Have taste for simplicity — you know when to build something clever and when to ship the simplest thing that works.
