We're looking for an experienced Staff Engineer / Technical Lead who thrives on solving complex engineering challenges and wants to play a key role in delivering large-scale software solutions within a highly collaborative environment.

This is an opportunity to take ownership of technical direction across a major programme, working on modern, cloud‑connected applications that integrate with a wide range of platforms and services. You'll remain hands‑on with development while providing technical leadership, influencing architecture, mentoring engineers and shaping engineering best practice.

If you enjoy working where the answers haven't already been defined, this role offers the autonomy, technical challenge and impact to make a real difference.

• Lead the technical direction for a cross‑functional engineering team.
• Design and build scalable backend services, APIs and full‑stack features.
• Architect integrations with external platforms including ERP systems, data platforms and third‑party services.

• Champion engineering excellence through code quality, testing, CI/CD and observability.
• Mentor Senior Engineers and help develop the wider engineering capability.
• Collaborate with Product Managers, Engineering Managers, designers and customer stakeholders to turn complex requirements into practical solutions.
• Remain hands‑on in the code while balancing technical leadership responsibilities.

You'll be an experienced software engineer operating at Senior or Staff Engineer level who enjoys both writing code and leading technical initiatives.

You'll ideally have experience with:

• Java backend development
• SQL and database design
• REST APIs and event‑driven architectures
• Angular or another modern front‑end framework
• System integration and distributed systems
• CI/CD pipelines and automated testing
• Cloud‑based architectures
• Technical mentoring and architectural leadership

About You

• Enjoys solving ambiguous technical problems.
• Leads through influence rather than authority.
• Communicates confidently with both technical and non‑technical stakeholders.
• Takes ownership from design through to production.
• Cares about maintainability, scalability and engineering quality.
• Enjoys helping other engineers grow.
