Job description

Software Architect

Based in Stevenage

Salary up to £80,000 + 21% bonus + strong benefits

Not every architect role lets you shape something that actually matters.

This one does.

You'll take ownership of the software architecture behind complex, real-world systems, defining how everything fits together, performs, and scales. Not just diagrams and theory, but architecture that drives delivery.

You'll already be an Architect.

Or you might be the person everyone turns to when the design decisions get difficult.

Either way, this is your step up.

What you'll be doing:

• Owning end-to-end software architecture across high-integrity systems
• Defining structure, interfaces, and real-time behaviour
• Turning requirements into robust, scalable designs
• Working closely with engineers, architects, and technical specialists
• Influencing tools, technologies, and long-term strategy

What you'll bring:

• Strong software design and architecture experience
• A background in complex or real-time systems
• Confidence making technical decisions that others rely on
• Ability to explain the "why" behind design choices
• Experience across multiple languages or tech stacks

Why this role stands out:

• Bonus up to 21%
• Pension up to 14%
• Clear route into senior / strategic architecture
• Hybrid working, typically 3-4 days on site
• Work that genuinely has real-world impact

You'll be working at the cutting edge of advanced engineering, building systems where performance, safety, and reliability are non-negotiable.

You're ready to move from contributing to architecture... to owning it, this is the move.
