About this role
At Lab49, our philosophy is simple: we give talented developers the tools, support and environment they need to push the envelope on every project. What makes us stand out is even simpler. We don’t settle for average products or ‘just good enough’ solutions. When you work here, you’ll always have what you need to go well beyond what already ambitious clients expect from us. Our work is fast and our work is good. Move from project to project, take on new challenges and develop new skills to meet them and you’ll discover what you can really do, faster than ever before.
You’ll work on some of the most varied and sophisticated technological challenges the industry has to offer. That means embracing difficult problems and being driven to achieve the ambitious. But you will never do it alone. You'll work alongside talented colleagues who relish the thrill of achieving what some see as impossible. It also means joining a community of like-minded people whose passion for technology and its potential goes beyond clocking in and out of a job. If you’re interested, you’ll have the opportunity to bring new technologies into our work, suggest fields we should be moving into or get stuck into research projects that are as much about intellectual curiosity as commercial value.
