If you’re thoughtful, collaborative, and eager to grow then we’d love to meet you!

What You Will Do

• Design and evolve backend systems and architectures to improve scalability, reliability, and long-term maintainability
• Analyse complex, legacy-heavy systems to identify risks, bottlenecks, and opportunities for simplification
• Develop and refine backend services and APIs with a strong focus on correctness, performance, and code quality
• Challenge technical assumptions and proposals by evaluating trade-offs and offering well-reasoned alternatives

• You apply strong analytical and critical thinking to break down complex problems, identify edge cases, and assess risks before implementation.
• You confidently challenge assumptions and use data, logs, or system insights to support your decisions and recommendations.
• You lead by example through influence, mentorship, and clear communication rather than formal authority.

Why should you join us?

• Engineers get a top-spec laptop, using the platform of their choosing
• Mental health support : access to Nilo.health platform if you could use a session with a psychologist.
