Role purpose

As a Lead Engineer, you will be the senior technical voice in a cross‑functional squad of around 5–7 engineers, setting the standard for inclusive, high‑quality engineering. You will partner closely with an Engineering Manager and Product Manager to design, build and ship well‑architected, scalable products and services that delight customers and create measurable business impact.

This is a hands‑on leadership role. You will spend much of your time designing solutions, writing and reviewing code, and guiding technical decisions, while also mentoring engineers and creating a supportive environment where people with different backgrounds can grow.

What you’ll do

• Lead the end‑to‑end design and development of scalable, high‑performance software across both client‑side and server‑side applications.
• Provide technical leadership for your squad, facilitating sound engineering decisions and promoting best practices in code quality, architecture, security and performance.
• Write and review production code every day, design and evolve APIs, and ensure solutions are robust, maintainable and well tested.
• Work across the full stack, collaborating with UX to build user interfaces and developing reliable APIs and services that power our products.
• Mentor and coach engineers at all levels, encouraging continuous learning, constructive feedback and knowledge sharing within the team.
• Design, deploy and operate cloud‑native applications on AWS using Terraform, Kubernetes and containerised workloads.
• Champion automated testing, TDD and CI / CD so that deployments are secure, reliable and frequent, with minimal manual intervention.
