A digital experience agency in the United Kingdom is seeking a Senior Full-Stack Developer to build high-quality digital experiences. The ideal candidate has 5+ years of hands-on development experience, strong skills in PHP, JavaScript, and React, and a builder’s mindset. Key responsibilities include developing robust applications, collaborating across teams, and implementing APIs. Applicants should thrive in ambiguity and embrace technical excellence. Join a dynamic team dedicated to innovation and excellence.
At Iris, our spirit is built on outsider thinking. We dive headfirst into the unknown, experiment relentlessly, and stay ahead of the curve. Technology is no exception.
As a Senior Full-Stack Developer, you’ll bring that same energy and curiosity to the engineering craft, building high-quality digital experiences that power the work our clients see, feel, and interact with. You’ll sit at the heart of our digital ecosystem, shaping the systems, frameworks, and code that keep our ideas moving and our creativity scalable.
This role is for someone who thrives in ambiguity, obsesses over clean architecture, and pushes for technical excellence while collaborating with multi-disciplinary teams across UX, design, strategy, and production.
You’ll build tools, platforms, and features that help Iris show up in culture and stay ahead of what’s next.
Passion fuels everything we do. You might be the loudest voice in the room or quietly crushing it behind the scenes. What matters is that you care. About the work. About the people. About the impact. We show up with energy, get involved, and make this place better every day for each other and for our clients.
We don’t wait for permission. We get stuck in. Iris people take ownership, stay curious, and never stop learning. We are always looking for smarter ways of working, new skills to master, and better answers to the briefs we’re given and even the ones we’re not. We don’t sit still and we don’t let opportunities pass us by.
Great work is our baseline. We push for better. We collaborate across teams, challenge the norm, and raise the quality of everything we deliver. Strong performance isn’t just about doing your part. It’s about growing the business, helping others succeed, and showing clients what Iris is made of.
We are proud to be an equal opportunities employer and recruit on talent alone, regardless of age, gender identity, ethnicity, religion, education, class, sexual orientation or disability. We champion diversity and believe it not only benefits, but enhances our creativity, our company and the wider society at large.
