HMRC is transforming the UK’s tax system through cutting-edge digital innovation and the Chief Digital and Information Officer (CDIO) Group is at the heart of that mission.

We are building high-quality digital services that will enhance the customer experience, enable real-time interactions, and make tax simpler and more intuitive for everyone. By equipping our colleagues with modern tools and technologies, we are also reshaping how we work — allowing HMRC to focus its resources where they can deliver the greatest impact.

The Multi-channel Digital Tax Platform sits within the Chief Enterprise Platform Office and is the backbone of HMRC citizen facing services.

These roles will place you within a team with the mandate to provide, maintain and optimise a Platform as a Service (PaaS), with the objective to provide business areas in HMRC and other departments the means to create, maintain and iteratively improve the highest quality services in Government. We provide the digital delivery teams with everything they need for developing, deploying and improving their services, from the underlying cloud-based PaaS to the tools for collaborative working, performance analytics and live service support.

Job description

Purpose of the Role

- The Platform is built and operated by a number of specialist teams and you will be placed on an established team of DevOps practitioners. We consider DevOps to encompass an approach to work that combines the ability to test, write and review code, alongside the capacity to troubleshoot operational problems in the cloud technologies we use. This becomes extremely effective when operating in agile teams, collaborating to achieve continuous delivery using open source software.

- All coding work will be done as part of a programming pair, and you must be adept at collaborating with others. All code will be stored with distributed source control, allowing wide collaboration across the department and beyond. The tools we use for metrics, logging and alerting, as well as configuration management and continuous integration are all open source, and you will need to be experienced at using these common tools, as well as investigating and quickly mastering new options as the PaaS continues to iterate and evolve.

Reporting Line

- You will have a Civil Servant Line Manager, but your daily work will be managed by your Team’s Product Owner and Delivery Lead (who will likely be a mix of Civil Servants and Contractors).

- You may also be required to Line Manage junior colleagues (O and/or HO level).

Person specification

Key responsibilities

- Maintain design and troubleshooting documentation.

- Improve the reliability of the platform.

- Build, maintain and continually improve the tools that we use to deploy and operate the software that we build. This includes automated build and deployment, secrets management, system observability, monitoring, log aggregation, scaling, and more.

- Develop tools and services useful in DevOps environments such as performance monitoring, security monitoring, deployment/configuration, continuous integration/build servers and cloud resource creation scripts.

- Contribute towards the ongoing development of junior colleagues.

- Seeking out opportunities to transfer knowledge from experienced developers.

Essential Criteria

- Experience operating on large scale government platform with multiple agents.

- Confident with programming languages and IaC (Infrastructure as code), and 3 years of experience of programming in Python and Terraform.

- Comfortable coding with distributed source control, such as Git.

- Solid understanding of agile development, Continuous Integration, Test Driven Development and version control.

- Developing on cloud-based environments like AWS.

- Experience leading a pair/mentoring junior engineers.
