We are seeking exceptional Senior/Principal Full Stack Engineers who combine deep technical expertise with strong product thinking and software craftsmanship.
This is a hands-on engineering role. Successful candidates will spend the majority of their time designing, building, and shipping production software while embedding modern engineering practices within the squad.
These engineers are expected to act as Engineering Catalysts—leading by example, improving engineering quality, accelerating delivery, and raising the capability of the wider team through day-to-day delivery.
Key Responsibilities
Deliver Customer Outcomes:
- Design, build, and deploy scalable, secure, and cloud-native applications across Marketplace and Conversion domains.
- Work closely with Product Managers, Business Analysts, Data Analysts, and QA to understand customer problems and translate them into technical solutions.
Lead Through Hands-on Engineering
- Lead technical delivery through hands-on software engineering.
- Build production-ready software every sprint.
- Pair programme with engineers to solve complex technical challenges.
- Drive pragmatic engineering decisions balancing speed, quality, and maintainability.
- Own technical implementation across the SDLC.
Embed Engineering Excellence:
- Champion software craftsmanship and clean code.
- Embed engineering standards and best practices into day-to-day delivery.
- Drive code quality through peer reviews and collaborative development.
- Promote reusable components, modular design, and maintainable solutions.
- Embed automated testing and secure-by-default engineering.
- Mentor engineers through pairing and technical leadership.
