.NET Tech Lead

.NET Tech Lead

Location: Southampton (2–3 days per week onsite, hybrid)

Salary: £80,000 – 100,000 + strong benefits package

The Opportunity

We are partnered with a growing, purpose-driven technology business in the green energy and sustainability sector, dedicated to supporting organisations on their journey to net zero. The company is scaling a new SaaS platform and digital services designed to help clients reduce carbon emissions, optimise energy usage, and drive real-world environmental impact. The team is currently small and needs a new tech lead to take the reins. You’ll spend about 70% of your time on development and code, and 30% on leadership, management and architecture. There are plans to grow the team, so over the next 2‑3 years this role will likely evolve into a manager of a larger engineering team.

This is the perfect opportunity for someone who is both a talented senior/lead developer and a strong process and people person. You will balance technical expertise with product and software architecture, leadership and mentoring.

Key Responsibilities

• Lead and grow a small, high-performing development team
• Drive the end‑to‑end design and build of SaaS products, from initial architecture to delivery
• Remain technically involved and hands‑on, particularly in C#, .NET, and Azure
• Implement engineering best practices: Agile/Scrum, CI/CD pipelines, and code quality standards
• Collaborate cross‑functionally with product and business stakeholders to translate requirements into scalable solutions
• Ensure performance, security, and reliability of cloud‑based systems
• Act as both a technical leader and mentor, fostering a culture of innovation and accountability

About You

• Strong technical background in C#, .NET, and Azure
• Experience managing and mentoring small development teams while remaining technically hands‑on
• Solid understanding of modern software development practices, cloud architecture, and Agile delivery
• Excellent communication skills, with the ability to work closely with both technical and non‑technical stakeholders
• Problem‑solving mindset and ability to thrive in a scaling environment where you can make a real impact

What’s on Offer

• Up to £100,000 salary + bonus, pension, holiday & electric car scheme
• Hybrid working model (2–3 days per week in Southampton HQ)
• Opportunity to lead, build, and deliver a SaaS platform with significant industry impact
• Modern, values‑driven working culture with strong investment in people and technology
