**** About the role
** Are you an experienced software engineering leader passionate about AI-enabled ways of working? If so, we want to hear from you! Haven is looking for a Lead Engineer to join our growing Technology team, taking joint ownership of the direction and output of a delivery squad alongside a Product Manager and UX Designer.

You'll set the technical direction, define the architecture, and be the key technical contact for squad stakeholders and the wider business. You'll shape how the squad adopts and continually improves AI-enabled engineering practices, ensuring work is well-structured, appropriately supported, and delivered to a high standard of quality, security, reliability, and maintainability.

This is a strongly hands-on role suited to a technical leader who thrives on building capable teams, coaching engineers, and staying close to the code. Typically you'll spend around 80% of your time hands-on in smaller teams (and 60% in larger ones), balancing leadership, mentoring, and stakeholder engagement across the software delivery lifecycle.  You will also commit to being part of our Engineering Lead community, actively contributing to developing the overall engineering standards across Haven, discussing and solving architectural challenges and providing peer support as appropriate.
