Job description

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.

Through our Guide, Build and Equip approach, we help organisations embrace change, deliver meaningful impact, and develop the skills they need to thrive in an increasingly agentic world.

About you:

• You care deeply about producing high-quality work that delivers real value
• You’re comfortable navigating ambiguity and solving complex problems collaboratively
• You bring strong expertise in your craft, alongside a willingness to keep learningYou communicate clearly and build trust quickly with clients and teammates
• You’re pragmatic, adaptable and outcome-focused
• You enjoy sharing knowledge and helping others grow
• You value low-ego collaboration and enjoy working as part of multidisciplinary teams

What you’ll bring to the table:

• Audit the existing colocation infrastructure, reviewing High-Level Designs (HLDs) and Low-Level Designs (LLDs) to ensure alignment with the deployed environment
• Validate compute and storage environments following build and non-production migrations, ensuring performance, resilience and operational standards are met
• Conduct capacity planning and resource analysis to ensure sufficient compute and storage headroom for upcoming tightly coupled monolithic migrations
• Identify infrastructure risks, performance bottlenecks and optimisation opportunities to improve efficiency and readiness for production workloads
• Ensure physical security, host isolation and infrastructure controls comply with financial services regulatory requirements before production deployment
• Collaborate with infrastructure, architecture and migration teams, providing technical guidance, documentation and assurance throughout the migration programme

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.
• Flexibenefit: £1000 assigned to you via our benefits portal to select or upgrade the benefits that suit you the most. Any unused allowance from the £1000 can be taken as cash.
• Life Assurance.
• Income Protection.
• Eye test + first pair of glasses.
• Parental Benefits: Generous Enhanced Maternity and Enhanced Partner (Paternity) Leave.
