Join Ordnance Survey – Shape the future of location data.

Ordnance Survey is the national mapping agency for Great Britain, and we’re transforming how the world uses location data. Our digital services, data pipelines and platforms support governments, businesses and developers every day. To keep innovating, we’re looking for an experienced Engineer to help us build secure, scalable and high‑quality software that makes a real difference.

As an Engineer, you will design, build and maintain software components that underpin Ordnance Survey’s products and services, working in an iterative, agile delivery environment. You will contribute hands‑on engineering expertise while improving how software is designed, delivered and operated across the team.

You will develop software components and modules involved in product generation, along with the supporting infrastructure they rely on. The role requires a Dev Sec Ops  mindset, combining sound software engineering, infrastructure awareness and security‑by‑design to deliver reliable, well‑tested and maintainable solutions.

You will be expected to take responsibility for the services you build through to production, supporting their operation and helping identify and resolve issues as they arise. You will collaborate closely with other engineers and contribute to improving the team’s capability in Scala, Databricks and secure engineering practices.

• Provide technical skills to continuously improve engineering capability across all stages of the engineering lifecycle.
• Develop infrastructure, coordinating with project management, geospatial engineers, data scientists and testers to ensure successful outcomes.
• Promote and actively share best practices across teams to drive consistency and quality.
• Operate and support the production services you build, finding opportunities to improve robustness, resilience and overall system stability.

We’re looking for someone who can build high‑quality systems, working with team members and stakeholders, developing and implementing best practices regarding infrastructure and Dev Ops.

• Experience in building, deploying, testing, debugging, scaling, and monitoring secure systems.
• Clear communication skills, with the ability to collaborate across technical and non‑technical stakeholders.
• Developing modules for use on Databricks and data access manager.
• Experience with automated access and security management.

• Developing and maintaining production infrastructure.
• Driving improvements in engineering techniques to increase performance of the system and the team.

• Azure Dev Ops and Azure Cloud Services (Entra, Batch, ADLS).
• Azure Infrastructure as code.
• Data Pipeline tooling (Databricks, Unity Catalog, Airtable, Spark, ADF).
• Experience with Scala, Bicep, Python, Power Shell.

We want you to love what you do and feel supported to do your best work.

• Competitive salary and pension (OS contribute up to 12.07%).
• Performance‑related bonus (where applicable).
• 28 days annual leave plus bank holidays (increasing with service).
• Enhanced family leave, including paid partner leave.
• Hybrid and flexible working options.
• Learning and development support, coaching and mentoring.
• Free subscription to OS Maps and access to wellbeing support.
• Volunteering leave and matched fundraising.

We embrace a hybrid working model at OS, because we believe in flexibility and balance. You’ll be based at our fantastic HQ in Southampton, Hampshire, where you'll spend 50% of your working week collaborating face‑to‑face with colleagues. It’s all about combining the best of both worlds – connection and autonomy – to help you thrive.
