Job description

You will work in one of our cross-functional, empowered engineering teams

Each team owns its part of the product and makes decisions jointly, alongside Product, Sales and other customer advocates

You won’t just build what someone else specifies; you will create new solutions to difficult problems and help take the platform to the next level

As a Senior Engineer, you will be a subject matter expert across multiple areas of the platform, involved in cross-team technical design, and independently responsible for the full lifecycle of the projects you deliver

At this level we expect your impact to reach beyond your own work: lifting your immediate team, and raising the bar across engineering as a whole through technical leadership, reviews and mentoring

We also want you to help shape how we build

AI is already core to our product, and it is changing how we engineer software just as fast

We want someone with the curiosity and judgement to help us adopt it well, across how the whole team designs, builds, tests and ships

Deliver features into the core product, across all areas of the technology stack

Own the full lifecycle of your work: design, development, deployment and ongoing support

Lead spikes and technical design for work that spans more than one team or domain

Code review your peers’ contributions and give clear, constructive feedback

Tackle gnarly data manipulation and scaling problems with a team of very bright people

Mentor engineers and lift capability across the wider engineering function, including in how we use AI

Qualifications

• Experience delivering and supporting resilient software that scales, in a multi-language, multi-technology stack
• Strong skills in automated testing (unit, end-to-end, performance, stress) and a high bar for quality
• Technical or team leadership experience, with practical experience of service-oriented architectures and container-based deployment (e.g. Kubernetes, Helm)
• Working knowledge of SQL and relational database concepts at scale, including performance optimisation
• A genuine interest in using AI to improve software engineering, with ideas (and ideally hands-on experience) for applying it individually and across a team’s pipeline
• Deep experience with Java or another statically-typed language, and familiarity with a web framework (Spring Boot or Ruby on Rails)
• Solid experience with a dynamically-typed language (e.g. Ruby); JavaScript, TypeScript and a front-end framework (React)
• Aptitude with CI/CD pipelines (GitLab preferred) and cloud computing, preferably AWS
• Experience with harness engineering or integrating AI / LLM-based tooling into a workflow or CI/CD pipeline, or with AI-assisted code review, test generation or developer productivity tooling
• Experience of architectural migration (e.g. service extraction or refactoring) and feeding observability or metrics systems
