Customer & Technical Engagement

• Facilitate technical discovery with customers — ask the right questions to surface real requirements around infrastructure, data access, security and user management
• Lead the technical narrative on every project — keep customers informed of blockers, expectations, and progress through clear documentation and direct conversation before issues escalate
• Explain technical trade-offs, delays, and decisions to customers with the right level of abstraction — communicate honestly about complexity, be clear on implications and free of unnecessary jargon

What we are looking for

Engineering Background & Delivery

• Expected to have 5+ years of software engineering experience — built, shipped and operated production systems with a strong understanding of what it takes to keep them running
• Strong technical foundation — able to have meaningful architecture discussions with technical and non-technical teams
• Proven track record of owning technical problems end to end — able to lead the technical response, produce incident reports, and release fixes directly into customer environments
• A genuine desire to work directly with end users — able to understand their pain points, come up with solutions, and provide technical continuity across the full project lifecycle
• Experience working across multiple customer environments simultaneously, managing competing priorities and keeping a clear picture of the technical state of each
• Ability to break down complex implementation work into clear, sequenced tasks — expected to estimate effort realistically and identify dependencies before they become blockers
• Ability to track and surface technical debt as a delivery risk — understands that shortcuts taken during implementation have a cost that needs to be managed
• Strong written communication — documentation, diagrams and run-books are clear, accurate and useful to both engineers and non-technical stakeholders

Technical Skills

• Worked with a production relational database (e.g. PostgreSQL), with solid understanding of joins, aggregations, indexing and how to optimise complex queries
• Familiar with shipping multiple TypeScript features to production, ideally working confidently across Node.js and Python
• Worked with Kubernetes or a comparable container orchestration platform and is comfortable with Docker
• Has solid understanding of Infrastructure as Code and has worked with Terraform, Helm, or similar tooling
• Worked with at least one major cloud platform; Azure or AWS are preferred but GCP is also considered
• Understands the importance of observability and has used a major monitoring platform such as Grafana in a production context
• Worked with CI/CD tooling beyond routine code contributions, including pipeline configuration and maintenance
• Has a strong understanding of networking fundamentals — firewalls, DNS, VPNs, and access control in the context of secure enterprise deployments
• Has interest in, or ideally experience with, AI-assisted tooling applied to deployment, testing, or operational workflows

Domain experience

• Track record working with NHS organisations and ideally life science industry players — understands the dynamics of implementing solutions in complex healthcare settings, including governance with many stakeholders
• Hands-on experience with healthcare data — knowledgeable about patient data, how it is structured, and why its sensitivity matters operationally and legally
• Experience in a startup or fast-paced scale-up environment where a good number of processes are being built or evolved rather than just followed

What does FITFILE offer?

• Location and flexibility: A virtual-first working model with genuine location flexibility, FITFILE team members meet fortnightly in London.
• Compensation: Competitive salary communicated during the recruitment process, with a benefits package reviewed regularly to remain attractive.
• Holiday: 25 days of annual leave plus UK bank holidays.
• Development: Structured support for training and personal development, with budget and time allocated rather than left to the individual to pursue.
• Culture and structure: A flat structure with experienced, results-oriented leadership. Engineers are expected and encouraged to contribute to how FITFILE builds, ships, and operates, this is not a company where process is handed down.
• Impact: Work on technically complex problems in a domain where the outcomes matter. FITFILE's platform directly enables better use of health data at scale, with real consequences for research and patient outcomes.
• Team: Regular team events and a genuine emphasis on a supportive, enjoyable working environment.
