Job description

About Us

We are an engineering driven company building best in class durability simulation software used to solve complex, real world problems. Our products are developed using a modern technology stack with heavy automation, CI/CD, and a strong emphasis on testing and software quality. We care deeply about how software is built, not just that it works. Good design, maintainability, leveraging new tools and technology (AI), testability, and long-term sustainability are central to everything we do.

The Role

We are looking for a Senior Frontend Developer to join our team and help build and evolve our React based user interfaces. This role is not about being the smartest person in the room, but about being a strong, proactive team contributor who raises the quality of the whole group. You will work closely with the Senior Developer leading the front end, contributing ideas, challenging assumptions constructively, and helping turn complex requirements into robust, user-friendly solutions.

What We Value Most

• Team player with a positive working attitude
• You collaborate openly, communicate clearly, and treat colleagues with respect.
• You care about the success of the team, not just your own output.
• You give and receive feedback constructively and contribute to a healthy engineering culture.
• Works well with front-end technical leadership
• You are comfortable working alongside the Senior Developer leading the front end.
• You can follow an agreed technical direction while contributing ideas and improvements.
• You know when to lead, when to support, and when to challenge - always in a professional, solution focused way.
• Takes initiative and ownership
• You actively look for problems before they become issues.
• You propose solutions, improvements, and refactoring rather than waiting to be asked.
• Strong technical skill and general problem solving ability
• You have solid experience building applications with React and Redux (or similar state management).
• You write clean, maintainable, well-tested code.
• You can reason about complex systems and make pragmatic trade-offs.

Key Responsibilities

• Design, build, and maintain front-end features using React and Redux.
• Collaborate closely with front-end leadership, back-end engineers, and other stakeholders.
• Contribute to code reviews with a focus on quality, maintainability, and consistency.
• Ensure front-end code is well tested and fits into our automated CI/CD pipelines.
• Identify opportunities to improve tooling, performance, reliability, and developer experience.
• Help uphold and evolve front-end standards and best practices.

What We’re Looking For

• Strong experience with modern TypeScript, React, and Redux.
• A quality focused mindset: testing, code reviews, and good design matter to you.
• Experience working in teams that value automation and continuous integration.
• Confidence to take initiative without ego.
• Curiosity, adaptability, and strong general problem solving skills.
• Experience with automated testing (unit, integration, UI).
• Familiarity with CI/CD pipelines and modern build tooling.

Nice to Have

• Experience working on technically complex or engineering heavy products.
• Knowledge of mathematics or signal processing, e.g. time series, histograms, Fourier analysis.

Why Join Us

• Work alongside some of the best and most passionate technology experts from around the world in a leading company within the test and measurement industry.
• You’ll work on challenging, meaningful engineering problems.
• Quality is genuinely valued, not just talked about.
• You’ll be trusted to think, contribute, and help shape how things are built.
• You’ll work in a team that cares about doing things well and improving over time.
• Remote working, generous holiday and benefits package.
