They’re now looking for a Software Architect to shape the next generation of their customer-facing systems; designing scalable, cloud-first solutions capable of handling high data throughput and large data sets.

The Environment

• AWS (cloud-first architecture)

Strong .NET Architects who’ve worked in modern cloud and micro-services environments, or who can operate confidently across Node/TypeScript ecosystems, are absolutely encouraged to apply.

The Role

This is ideal for someone who has progressed from hands-on engineering into architecture and still understands what great code and great systems look like.

You’ll:

• Lead microservices and event-driven design initiatives
• Champion DevOps-aligned architecture patterns
• Work across distributed/offshore teams
• Operate comfortably at both strategic and deep technical levels
• Influence AI architecture and modern data practices

What We’re Looking For

• 3–5+ years in a Software Architect role
• Strong engineering background (C#/.NET or modern JS/TS stacks)
• Experience within mature B2B SaaS environments
• Deep knowledge of cloud architecture (ideally AWS)
• Experience with microservices, event-driven systems
