Team Lead - Software Development

The Role

We are looking for an experienced Software Development Team Lead to play a key role in the delivery and evolution of our software platform. This is a hands‑on leadership role, combining active contribution to software development with responsibility for guiding and enabling a high‑performing engineering team.

You will be involved in delivery planning, technical design, and architecture, collaborating with Product Managers and Product Owners to provide technical input and ensure solutions are feasible, well‑designed, and aligned with long‑term platform health. A core part of the role is communication, working closely with engineering, product, and wider stakeholders to share delivery progress and technical context, and to ensure the development team has clarity and support throughout delivery.

You’ll be expected to lead by example: contributing directly to code, reviews, and design discussions, while creating an environment where engineers can do their best work and continue to grow.

This role suits someone who enjoys ownership, thrives on solving complex problems, and takes pride in both the quality of the software and the effectiveness of the team delivering it. You are genuinely curious about technology and motivated to keep learning, often exploring ideas, tools, or projects beyond your day‑to‑day responsibilities, and you bring a positive energy that helps create an enjoyable, engaging team environment.

• Support sprint planning, estimation, and delivery, helping the team meet commitments
• Balance delivery priorities with long‑term technical health and manage technical debt

• Work closely with product owners, designers, and other engineering teams to deliver high‑quality solutions
• Act as a key technical point of contact, translating business requirements into effective technical solutions
• Promote collaboration, knowledge sharing, and a positive team culture

• 5+ years of commercial software development experience using recent versions of C# .NET
• Experience contributing to the technical design and architecture of web applications
• Experience developing with Cloud services, preferably AWS

• Strong written and verbal communication skills
• Proven ability to guide teams through ambiguous or complex technical challenges
• A proactive, hands‑on, and ownership‑driven mindset
• Able to work collaboratively with cross‑functional teams
• Resilient, adaptable, and comfortable balancing development work with leadership responsibilities
