Who We Are:

We’re on a mission to close the world’s tech skills gap. We help organisations navigate the future of technology, combining human expertise, emerging tech and AI to deliver better outcomes, faster. Since 2014, we’ve worked side-by-side with clients to solve complex challenges, build high-performing teams, and create lasting capability. As technology continues to evolve, we believe the most successful organisations will be those that combine the best of both: human ingenuity AND intelligent technology. That belief is embedded in everything we do. We call it the genius of the AND: deep expertise AND practical delivery, innovation AND responsibility, ambitious work AND sustainable careers.

Why join AND Digital?

We’re building a culture where talented people can do meaningful work, continue growing, AND enjoy the journey along the way. Our model is designed to build belonging and connection: we’re organised into regional ‘Clubs’ of no more than 80 people, so you (and our clients) get the benefits of that small company feel while also being connected to a larger whole. Our Practice Areas act as a ‘second home’ for our ANDis - a place where you can innovate and learn with like-minded experts who care deeply about their craft, support each other generously, and believe the best ideas come from collaboration, not hierarchy. Our culture is rooted in our values of Wonder, Share and Delight, and shows up through five traits that we celebrate and nurture in all our ANDis: we value curiosity, ambition and a growth-mindset. We are deeply client-centric. Most important of all we are human - we create an inclusive environment where people feel trusted, supported and able to be themselves.

By joining AND, we’ll provide:

• 25 days bookable holiday + flexible Bank Holidays
• Pension: 6% of salary paid by AND Digital with a further 2% paid by you (can be increased by choice).
• Aviva healthcare cover (including pre-existing condition cover) for you.

• Parental Benefits: Generous Enhanced Maternity and Enhanced Partner (Paternity) Leave.
