Job description

Senior Software Architect – AI-led Development

We’re currently recruiting Senior & Lead Software Architects for an established technology business transforming its software platform through AI-led design and development.

This is an opportunity to own architectural direction and help shape how AI is used throughout software delivery, from initial design through implementation, testing and validation.

The core technology stack is C# and .NET, although the business is open to architects with transferable experience. Strong architectural judgement and practical use of AI matter more than an exact technology match.

The role

• Own architecture and design decisions for a complex cloud platform.
• Guide the development of secure, scalable and maintainable software.
• Apply AI tools across design, development and testing, critically reviewing their outputs.
• Work closely with engineering and product teams, sharing knowledge and setting technical direction.

About you

You’ll be an experienced Software Architect with a strong software engineering background and experience designing cloud applications. You already use AI tools in your day-to-day work and can explain where they add value and where human judgement remains essential.

You don’t need to be an AI specialist or hold formal AI qualifications. This is a hands‑on individual contributor role, with opportunities at Senior or Lead Architect level depending on experience.

The package

£90,000 - £110,000 depending on experience, plus an 8–10% bonus, pension and medical insurance.

Hybrid working includes 2 office days each week in Southampton, near Eastleigh, Fareham, Whiteley.

Applicants must be eligible for UK Security Clearance. The two-stage interview process includes a practical session using AI tools.
