Full Stack JavaScript/TypeScript Engineer

SUMMARY:
We are looking for a Mid-Senior Full Stack JavaScript/TypeScript Engineer to join a Commercial Engineering team working on business-critical digital publishing and advertising platforms.
This is a long-term opportunity within a complex, high-traffic production environment, combining ongoing platform enhancement, modernisation and migration work. The role is technically full stack, with an approximate 70/30 frontend-to-backend split, although the frontend work is focused on browser-level engineering rather than traditional UI or React component development.
WHAT WILL YOU BE DOING:
As part of an agile software development team, you will:

- Develop and maintain software using JavaScript, TypeScript and Node.js.

- Working directly with vanilla JavaScript, the DOM and browser APIs.

- Building and maintaining plugin and configuration systems.

- Working with third-party script integrations across commercial and advertising platforms.

- Contributing to browser-level functionality, including DOM manipulation, scheduling and brokers.

- Working with analytics and consent management (CMP) integrations.

- Contributing to the ongoing development and modernisation of high-traffic production platforms.

- Supporting a mixture of BAU enhancements, platform evolution and migration work.

- Working within existing CI/CD, containerised and Kubernetes-based environments.

- Collaborating with an experienced engineering team to solve technical problems and deliver reliable, maintainable solutions.

- Taking ownership of problems and using initiative to identify and implement effective solutions.
WHAT WE ARE LOOKING FOR:

- Strong commercial experience with JavaScript and TypeScript.

- Strong hands-on experience with Node.js.

- Proven experience working with vanilla JavaScript.

- Strong familiarity with the DOM, browser APIs and the inner workings of modern browsers.

- Strong software engineering fundamentals.

- Experience developing and supporting software in production environments.

- Comfortable working with CI/CD and containers.

- Familiarity with working in a Kubernetes environment.

- Strong problem-solving skills and the ability to use initiative.

- Comfortable working across both frontend and backend areas of a system.

- Ability to work effectively within an established engineering team and complex production environment.

- Strong focus on code quality, maintainability and engineering best practices.

- Strong verbal and written communication skills in English
NICE TO HAVE:

- Experience with CSS and browser layout.

- Previous experience within digital publishing, advertising technology or high-traffic web platforms.

- Experience with third-party script integrations.

- Exposure to analytics platforms.

- Experience with Consent Management Platforms (CMPs).

- Experience contributing to platform modernisation or migration projects.

- Good use of LLM/AI tooling as part of the software development workflow.
WHAT’S IN IT FOR YOU?

- Be part of our collegial environment where responsibility and authority are shared equally amongst colleagues and help create our company culture.

- A culture in which we don’t criticise failure but ensure we learn from our mistakes

- An Agile environment where your ideas are welcome
