Clear the path. Seek the story. Do what matters.
Who we are
We are Ordnance Survey, Great Britain’s national mapping service and a pioneer in geospatial technology. With over 230 years of trusted data, we empower better decisions, deeper understanding, and meaningful connections to the places we live, move through, and care for.
Our Principles
At OS, how we work matters just as much as what we deliver. We are guided by three principles and will be use these to assess competencies during the hiring process:
Clear the path – Cut the noise, simplify and remove blockers so work can move at pace
Seek the story – Listen fully, build understanding, fact‑check assumptions and speak up
Do what matters – Focus on value, make deliberate stop/start/continue decisions, and recognise the contribution of others
We are recruiting for at least two engineers to join our Cloud Platform and Productivity Platform teams.
Together, these teams provide the secure, scalable, and developer friendly cloud platform that underpins OS’ geospatial solutions.
Cloud Platform focuses on Microsoft Azure Landing Zones, networking, governance, identity, and platform security.
Productivity Platform focuses on developer experience, effectiveness, automation, and tooling that enables product teams to deliver safely and at speed.
These roles offer the chance to help shape our platform vision, improve developer experience and delivery efficacy, and influence the engineering standards used across the organisation.
We do not expect one person to match every skill listed. We are intentionally building a complementary team, and we welcome candidates with emphasis in cloud engineering, software engineering, or developer productivity. If you can meet some of our needs and are willing to grow other skills, we are keen to receive your application. We cross-skill our teams and we value generalists — you can expect to learn new things!
You’ll work on a selection of the following, depending on your strengths:
Implement, support, and maintain our Azure Cloud Platform.
We are particularly keen to add more Azure Networking experience to our team - if this is your area, you’ll have significant influence on our platform evolution.
Deliver high quality software and infrastructure components using modern engineering practices.
Ensure software is secure, robust, and thoroughly tested.
Support and operate the services you build, proactively identifying and resolving issues.

About You
We welcome candidates who specialise more strongly in Azure infrastructure, software engineering, or developer productivity tooling — and we are looking to build a balanced team across those strengths. We’re looking for you to evidence a subset of the following; you do not need to tick every box.
Experience in provisioning, deploying and maintaining Azure infrastructure, especially any of:
Azure Landing Zones and the Cloud Adoption Framework
Azure Networking
Azure Policy, including authoring of custom policies
Management and security hardening of Virtual Machines using Desired State Configuration
Creation of Virtual Machine images using Image Builder / Packer.
Strong experience in software engineering and modern development practices.
Specific language experience is not required – you must be able to evidence valuing good practice in OOP languages, an appreciation of TDD, and a willingness to learn PowerShell and/or C#.
Holding current relevant Microsoft certifications such as Az-104, Az-700 and Az-500 or a willingness to gain Microsoft Azure Certifications – Ordnance Survey will fund the exams.
Strong experience in pipelines and IaC.
Ours are mainly Azure Pipelines, and Bicep, but experience in similar technologies is relevant.
Regardless of skills, we expect every candidate to be able to evidence the basics:
Competent use of source control and editors/IDEs
Good grasp of cloud computing principles
Passion for mentoring and sharing knowledge with others
Enthusiasm for learning new skills and staying up to date.
Thriving in an agile, collaborative environment
If you'd like to learn more about the role and the people with whom you'd be working, we plan to host two open sessions on Teams week commencing 4th May 2026.
These sessions are informal, completely optional, and do not form part of the interview process. They are an opportunity to learn more and to ask questions. They will not be recorded.
Please email careers@os.uk to register your interest and we will confirm session times and availability.

Security
OS conducts pre-employment checks for anyone made an offer of employment, including identity, right to work, employment history and criminal record checks (via Disclosure & Barring Services (DBS).
Some of our roles may require additional security vetting. We will advise candidates during the recruitment process if additional vetting may be required for that specific role.
