Job description

PERSON SPECIFICATION

We welcome applications from anyone with the skills we consider to make a good frontend developer, even if you’re not currently in a frontend developer role.

We are looking for people with experience in the following:

• frontend development with Javascript, HTML and CSS
• React or other frontend JavaScript frameworks
• NodeJS, Express and TypeScript
• using and contributing to component and pattern libraries
• version control tools, such as git
• automated testing, for example with Jest or Cypress
• building CI/CD workflows, ideally with GitHub Actions
• building and deploying containerised applications in the Cloud, ideally with Kubernetes and AWS
• building services that meet WCAG accessibility requirements

Willingness to be assessed against the requirements for BPSS clearance.
If you don’t have experience in all of these then that’s all right. We get it, it’s a long list! We encourage you to still apply and give us the chance to consider your application. A key attribute we’re interested in is the willingness and ability to learn. Learning and development is something we value and prioritise within our community.
There are some tips toward the end of this advert about how to apply - we strongly recommend you read these, especially if you’re new to applying for roles in the Civil Service.
The Civil Service is committed to attract, retain and invest in talent wherever it is found. To learn more please see the Civil Service People Plan and the Civil Service D&I Strategy.

OUR TECH STACK

Within Justice Digital we use a range of technologies. We’re looking for people who specialise in one or more of them and who love learning new languages and frameworks.
For the CJS Dashboard, we use a Python framework called Plotly Dash, which is built on top of Plotly.js, React and Flask. We test, build and deploy our service using GitHub Actions and host it on the MoJ Cloud Platform, which runs on Kubernetes and AWS. We use components, styles and patterns from the GOV.UK Design System where we can.

We’re recruiting Senior Frontend Developers at Justice Digital, to be part of our Criminal Justice System (CJS) Dashboard team.
This role aligns against the Senior frontend developer role from the Government Digital and Data Framework
The CJS Dashboard provides the public, Ministers, senior officials, policy colleagues, and local decision-makers with trusted data and metrics about the performance of the criminal justice system.
The Dashboard enables these users to understand the system and make informed decisions to improve performance.
We are working with the CJS Data Improvement Programme to iterate and improve the service to make things simpler, faster and better for people working in Local Criminal Justice Boards, leveraging more timely, linked data.

As a senior frontend developer, you will:

• lead frontend development of the CJS Dashboard and other dashboard products
• develop, test and implement accessible frontend components, including new components to visualise data, metrics and insights
• champion accessibility and ensure the service meets government accessibility requirements
• work with designers and user researchers to build, test and iterate prototypes and mockups
• stay up to date with emerging technologies and identify opportunities to incorporate these into the service
• write clean, well-tested code that follows web standards
• coach and mentor more junior colleagues
