The Company

At Amber Labs, we're a cutting-edge UK and European technology consultancy that empowers autonomy, promotes experimentation, and drives rapid learning to deliver exceptional value to our clients. Collaboration sits at the heart of our culture — every team member, regardless of role, works together to minimise risk and accelerate delivery. Our teams consist of highly skilled engineers, designers, analysts, and consultants dedicated to building world-class digital services for government and enterprise clients.

About the Role

We're seeking an experienced Senior Front-End Engineer to lead the development, modification, and maintenance of the front-end elements that users interact with across our government service platforms.

You'll work in multidisciplinary teams, collaborating with designers, developers, and user researchers to deliver accessible, performant, and standards-compliant services that meet the needs of real users and align with government digital standards.

This role is about setting the bar for front-end quality, defining best practices, ensuring accessibility and performance, and applying modern development techniques. You'll champion progressive enhancement, responsive design, and usability across multiple browsers and devices.

Key Responsibilities

Lead front-end development across multiple digital service projects.

Build accessible, responsive user interfaces that meet GDS accessibility and usability standards.

Ensure products are built with modern web development techniques and principles.

Collaborate with multidisciplinary teams, including UX designers, back-end developers, and testers.

Maintain high code quality through code reviews, testing, and documentation.

Optimise web performance and maintain browser/device compatibility.

Mentor junior developers and promote a culture of continuous improvement.

Contribute to design system evolution and reusable component libraries.

Key Skills & Experience

Proven experience as a front-end developer in production and prototype environments.

Strong proficiency in HTML5, CSS3, and JavaScript (including Node.js, ReactJS, ExpressJS, Mongoose).

Experience with templating and UI frameworks such as Nunjucks, Freemarker, Bootstrap, LESS, and SASS.

Working knowledge of CI/CD tooling such as Git, GitLab CI, Jenkins, SonarQube, Nexus, and Artifactory.

Deep understanding of accessibility, progressive enhancement, and performance optimisation.

Experience building services that perform efficiently across multiple devices and browsers.

Strong understanding of UX principles and user-centred design.

Experience working in Agile delivery teams.

Clearance Requirement

Must hold active SC clearance

We are unable to consider candidates requiring visa sponsorship at this time.

Benefits

Competitive salary and performance-based bonus structure.

Opportunity to work on impactful government digital services.

Hybrid and flexible working arrangements.

Private medical insurance (Aviva).

Company pension plan (Nest).

25 days annual leave plus UK bank holidays.

Access to Perkbox – employee discounts, perks, and wellbeing resources.

Inclusive and collaborative company culture that values experimentation and innovation.

Choice of device – PC or Mac.
