You’ll work closely with software and platform engineers throughout the development lifecycle, shaping testing approaches and embedding quality into delivery.

Security & Location Requirements
- UK citizen with at least 10 years UK residency
- Must already hold high-level UK security clearance
- Willing to travel to customer sites in Cheltenham
- Salary band: £40,000-75,000, depending on experience (we may consider more junior or more senior outside this range for the right candidate)
- 10% clearance bonus
- 25 days annual leave plus bank holidays
- Buy or sell up to 5 days leave per year
- 8% employer pension contribution
- BUPA health cover
- Life cover of 4× salary

Every employee has an individual training and career development plan. We recognise that everyone learns differently and we actively support long-term growth.
Our Process
We keep things straightforward and human:
- A 30-minute introductory chat with our recruiter, Sarah
- A 1-hour Microsoft Teams interview or on-site interview with two members of the team
- An informal conversation with two of our Founders
We believe open, organic conversations are the best way for both sides to decide if the role is the right fit.
