Full job description

Description

Please note: This role requires applicants to hold active, or recently active, SC or DV clearance.

This role also requires applicants to be willing to work on-site up to 4 days per week.

At Gemba Advantage, we build secure, user-centred digital products for critical public sector organisations across the UK. Our teams work on complex, high-impact systems, the kind that have to be secure, scalable, and actually usable by the people who rely on them.

We’re looking for Senior and Principal Engineers who want to shape meaningful systems, influence technical direction, and work alongside capable people who care about doing the job properly. You’ll help design and build modern cloud-native services, guide engineering standards, and solve genuinely hard problems with our customers.

The Role:

Design and deliver secure, scalable software in small agile teams
Stay hands-on while shaping architecture and technical direction
Set engineering standards and mentor others
Work directly with customers to solve complex problems
Champion modern engineering practices (cloud, CI/CD, DevSecOps)

What you'll bring:

Active, or recently active, SC or DV clearance (essential)
Strong experience delivering production systems in complex environments
Depth in at least one modern language (Java, TypeScript, Python, Go etc.)
Cloud/container experience and a security-first mindset
Confidence influencing technical decisions and improving teams

Tech we commonly use

Java • TypeScript • Python • Go
React / Angular
AWS • Kubernetes • Docker
Elasticsearch • MongoDB • relational DBs
CI/CD • GitOps • infrastructure as code

Why join Gemba?

We’re guided by four core values that make Gemba a great place to work:

Our people are our most important asset, and we prioritise their needs.
We succeed and fail as a team, not as individuals.
We do the right thing and we do the thing right.
We keep an unwavering focus on the customer’s needs.

Away from our values, Gemba offers an excellent and comprehensive package to our Gembans, including great salaries, meaningful perks, a culture of truly rewarding and celebrating success, amongst many other core benefits like flexible pensions and PMI.

As an Equal Opportunity Employer, we recognise, and studies confirm, that often underrepresented candidates in the workplace are less likely to apply to roles unless they meet all skills and experience of the position.

At Gemba we celebrate diversity and are committed to creating a diverse and inclusive workplace, therefore we make sure that our recruitment and selection processes never discriminate based upon age, race, religion, disability, sex, sexual orientation, gender reassignment, marriage and civil partnership, or pregnancy, and actively welcome applications from all groups.

About Gemba Advantage

Gemba Advantage make high-impact software that is secure, scalable and sustainable. Our experience and expertise allows us to succeed inside and alongside our customers’ exacting operational environments. We make software that makes a difference.
