Job summary
The Department for Business and Trade (DBT) has a clear mission - to grow the economy. Our role is to help businesses invest, grow and export to create jobs and opportunities right across the country. We do this in three ways.
Firstly, we help to build a strong, competitive business environment, where consumers are protected and companies rewarded for treating their employees properly.
Secondly, we open international markets and ensure resilient supply chains. This can be through Free Trade Agreements, trade facilitation and multilateral agreements.
Finally, we work in partnership with businesses every day, providing advance, finance and deal-making support to those looking to start up, invest, export and grow.
The Digital, Data and Technology (DDaT) directorate develops and operates tools and services to support us in this mission.
About the role
As a Senior Site Reliability Engineer (DevOps), you will play a key role in designing, building and running reliable, scalable and secure platform services that underpin critical DBT digital products. Working in multidisciplinary, agile teams, you’ll help ensure development teams have the tools and support they need, from observability and monitoring through to CI/CD pipelines so services are resilient, performant and centred around user needs. You’ll champion good engineering practices, helping teams use data and insight to continuously improve how services are delivered and operated.
This is a hands-on role where you’ll spend much of your time building and improving platform capabilities directly. You’ll work closely with product managers, architects and engineers to improve reliability and reduce operational burden, while also supporting and mentoring others across the engineering community. You’ll contribute to building and scaling our global platform, support live services through an on-call rota, and play an active role in initiatives such as enhancing observability and streamlining deployment processes to improve service quality and delivery outcomes.
