Senior software engineers, fluent in AI

Build, modernise and look after the products and systems your work depends on, from a new app to the legacy system nobody else wants to touch. Our engineers use AI tools every day, so your projects move faster.

What our engineers work on

Web, back end and APIs

Python, JavaScript, TypeScript, React, Node.js and .NET, for supporter portals, case management tools, internal systems and the APIs between them.

Mobile

iOS, Android and Flutter apps for the people you serve, your volunteers and your staff.

Legacy modernisation, CI/CD and cloud

Upgrading ageing code and infrastructure, adding version control and automated deployments, and moving to modern cloud hosting.

AI-assisted development and workflow automation

Engineers who use AI tools to write, test and review code faster, and who automate the manual steps in your processes.

AI, used where it saves real time

Our engineers use AI tools every day to write, test and review code, so your projects move faster without cutting corners.

We also help you use the AI features inside the platforms you already run, such as Copilot, Agentforce and workflow automation, where they make a real difference to your team.

How you can work with us

Whichever you choose, you get one accountable account lead, English-law contracts and people working UK hours.

Start with a Health Check

Not sure where to begin? Our Tech Health Check is a fixed-scope review that tells you what's working, what's at risk and what to fix first. Run it on its own, before a placement, or alongside someone already working with you.

About the Tech Health Check

Someone in your team

Experienced engineers who join your team, work your hours and learn your systems, without the cost, delay or risk of a permanent hire. 14-day risk-free trial, then a simple monthly fee.

Find a software engineer

On hand when you need them

A named software engineer you can call on for fixes, changes and questions, without a full-time hire. The same person each time.

Talk to us about support

Many organisations do both: a Health Check first, then a specialist to fix what it finds. How we work

Tech Health Check

A clear picture of your software before you change it

A fixed-scope review of your software and the team around it. It tells you what's working, what's at risk and what to fix first, whether or not you work with us afterwards.

  • Your codebase: quality, dependencies and what's out of date
  • Infrastructure and hosting
  • Security
  • Deployment: version control, testing and CI/CD

Frequently asked questions

How quickly can you find an engineer?

Most roles are filled within 2 to 4 weeks. Our pre-vetted network lets us find people who match your technical needs and your culture quickly, and for urgent needs we can often share a shortlist within 72 hours.

How do you vet your engineers?

Technical assessments, live coding, portfolio reviews and behavioural interviews. We look at problem-solving, communication and alignment with mission-driven work as well as technical skill. Only the top 5% of applicants make it into our network.

Can you take on our legacy system?

Yes. A Tech Health Check is a good place to start: it shows what you have and what to fix first, before anyone changes a line of code.

Can we scale up or down?

Yes. You can add engineers as projects grow or reduce the team when you need to, from a single developer to a whole remote team.
