We are looking for an experienced hands‑on Tech Lead to lead engineering within the application layer of our SaaS platform.

You will lead a small cross‑functional engineering pod responsible for building and evolving the services that power our product experience. The role combines hands‑on software development, technical leadership, and architectural ownership. You will also line‑manage the engineers in your pod, taking responsibility for their performance, growth, and wellbeing.

We expect our Tech Leads to be exceptional engineers first — people who lead through the quality of their thinking and the systems they build. A key part of this role is driving engineering leverage: modern development tools, automation, and AI‑assisted coding allow small teams to achieve dramatically higher productivity. You will help embed these practices into everyday engineering work while maintaining high standards of reliability and maintainability.

• Familiarise with the systems with which your team works
• Understand the overall architectural landscape in which your systems live
• Begin driving solutions within your domain, and making positive contributions to the solutions of others via architectural reviews
• Gain an in‑depth understanding of the production environment setup, CI/CD pipeline, and deployment approach
• Familiarise with and begin monitoring the operational data and metrics from the production environment
• Become productive and begin delivering at your true pace
• Build relationships cross‑team and cross‑function
• Understand the team processes and cycles, and start forming ideas on how they can be improved
• Develop a solid grounding in your understanding of the business and how it operates

You will design and build the services that deliver core product capabilities. This includes:

• Designing maintainable service architectures
• Implementing high‑quality production code
• Ensuring services are scalable, observable, and reliable
• Evolving systems as product requirements grow

You will guide the technical direction of the services owned by your pod. This includes:

• Shaping architecture and technical design
• Making pragmatic trade‑offs between speed and sustainability
• Ensuring strong engineering practices across the team
• Contributing to cross‑team architectural discussions

You will lead primarily through technical credibility and example.

Your responsibilities include:

• Running regular 1:1s and providing ongoing feedback
• Supporting each engineer's professional development and career growth
• Setting clear expectations and holding people to account
• Creating a psychologically safe environment where people feel free to highlight risk, challenge ideas, and acknowledge mistakes
• Contributing to hiring decisions for your team
• Fostering a culture of personal development and individual accountability, challenging engineers to constantly push their boundaries

A central part of the role is improving how the team builds software. You will:

• Remove technical bottlenecks and sources of friction
• Simplify architecture where possible
• Improve development workflows and CI/CD processes
• Introduce automation where it improves delivery speed or reliability

Your goal is to increase the team's delivery capacity without sacrificing quality.
