I am partnering with an early-stage UK tech startup focused on using data and AI to optimise and accelerate the design of clinical trials.
Location: London, UK (on-site/hybrid)
About the Role
I am seeking a highly experienced Senior Back-End Engineer to join a fast-growing, deep-tech venture at an early stage. As a key member of the founding engineering team, you will shape and build the core server-side architecture that underpins their next-generation platform. You’ll work closely with product and engineering leadership to design, implement, and scale reliable backend services, APIs, and systems — helping to turn cutting-edge ideas into real-world products.
What You’ll Do
- Lead the design, development, and maintenance of scalable, secure, and high-performance backend services and APIs.
- Collaborate across the engineering team — including frontend, product, and QA — to architect solutions that address business needs and technical challenges.
- Drive the full development lifecycle: requirements, design, implementation, testing, deployment, and support.
- Improve and optimise existing systems for performance, reliability, and maintainability.
- Conduct code reviews, provide technical leadership, and mentor junior engineers to uphold best practices.
- Identify and address security, performance, and scaling bottlenecks.
What We’re Looking For
- 5+ years of hands-on experience building backend systems in a production environment.
- Strong experience with backend languages and frameworks (e.g., Java, Spring, Python, Go, Node.js — adaptable to your stack).
- Proven track record designing and implementing RESTful APIs and microservices.
- Solid understanding of databases (SQL and NoSQL) and effective data modeling.
- Familiarity with cloud platforms (AWS, GCP, Azure) and CI/CD pipelines.
- Experience with performance optimisation, security best practices, and scalable architectures.
- Excellent communication skills and ability to work effectively in an agile, cross-functional team.
Nice-to-Have
- Experience with distributed systems and asynchronous architectures.
- Knowledge of observability tools, testing frameworks, and containerisation (Docker, Kubernetes).
- Previous involvement in early-stage or founding engineering teams.
Why Join?
- Play a pivotal role in shaping a product from the ground up.
- Influence technical direction and engineering culture.
- Work in a collaborative, fast-paced environment where your impact is visible.
- Competitive compensation and growth opportunities.
