QSafe is a UK-based deep-tech cybersecurity startup building the next generation of post-quantum security solutions. We help organisations identify, assess, and mitigate emerging quantum threats — preparing them for one of the most significant security transitions of the coming decade. An alumnus of Innovate UK's CyberASAP programme, we work at the intersection of cybersecurity, cryptography, and AI to solve problems most organisations are only beginning to understand.
We're a small, founder-led team shipping a real product to real customers. There are no layers here — everything you build goes into production, in front of users, and your decisions directly shape both the product and the engineering culture around it.
We're hiring a Full-Stack Developer to help build the QSafe platform. This is a high-ownership role: you'll design, ship, and run significant parts of a production system, working directly with the founders and technical leadership.
Quantum computing is set to reshape how the world secures its data, and organisations everywhere are beginning to prepare. QSafe is building the tools to help them. This role is a chance to join early, grow with a fast-moving startup, and do the best engineering work of your career on a problem that genuinely matters.
What Success Will Look Like
- Own features end to end: design, build, and ship FastAPI backend services and React interfaces — from concept to production to iteration.
- Design for data at scale: model and optimise PostgreSQL schemas and Redis caching strategies that keep the platform fast and reliable as it grows.
- Run production with confidence: deploy and operate services on Linux with Docker, Nginx, and GitLab CI/CD — you build it, you run it, and you make it observable.
- Build secure by default: we're a security company; secure coding practices and careful handling of customer data are table stakes, not afterthoughts.
- Drive execution: trace issues across the full stack, fix root causes rather than symptoms, prioritise ruthlessly, and keep shipping.
Who You Are and What You've Done
- You have 3–5 years of professional full-stack experience with production systems you've genuinely owned — not just contributed to.
- You write strong, clean Python and have built and versioned real-world APIs with FastAPI or a comparable async framework.
- You're solid in React — component architecture, state management, and an eye for interfaces people actually enjoy using.
- You're confident with PostgreSQL and Redis — schema design, query performance, and caching strategy come naturally to you.
- You're at home on Linux servers — Docker, Nginx, and CI/CD pipelines are part of your daily toolkit.
- You have a debugger's mindset — you enjoy the hunt, read logs and stack traces carefully, and write the fix plus the test that proves it.
- You thrive in startup ambiguity — you communicate clearly in a remote team and would rather ship and iterate than wait for perfect specs.
- Bonus: an interest in cybersecurity or applied cryptography — genuine curiosity counts as much as experience.
