About this job
As a Senior Software Engineer at iCrossing, you’ll play a key role in designing and delivering innovative, immersive digital solutions for our clients. Working closely with product, design, and engineering peers, you’ll lead the delivery of core digital projects across a range of stakeholders and business needs, contributing across the full development lifecycle—from technical design and architecture through to build, release, and ongoing improvement.
You’ll design and build clean, reusable, and well-documented code across the stack, with a strong focus on performance, scalability, and maintainability. The team leverages a modern technology stack—TypeScript,, AWS, and React—to deliver impactful, scalable digital experiences.
Alongside hands-on development, you’ll help shape engineering standards and workflows, contributing to code reviews, technical decision-making, and continuous improvement across the team. You’ll work confidently across frontend and backend technologies, collaborating closely with others to solve complex technical challenges.
You’ll also support the growth of the wider engineering team through mentoring and knowledge sharing, while staying up to date with emerging technologies and best practices. As a senior engineer, you’ll balance delivery with quality, helping ensure we build reliable, scalable digital solutions that deliver long-term value for our clients.
This is a full-time role and requires 2 days per week in the Cardiff or London office. You must have the Right to Work in the UK as unfortunately we are currently unable to sponsor those who require a visa.

We Before Me: lead for others. The sum is always going to be greater than the parts.
We evolve clients for a human-centric future - creating a better world for everyone.
