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 learning
• You 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

• Review and optimise the existing network topology to ensure it is fully prepared for the migration of critical production workloads.
• Analyse Data Centre Interconnect (DCI) performance and live traffic patterns, validating bandwidth and network capacity ahead of the monolithic cutover.
• Fine‑tune routing protocols, network paths and edge configurations to minimise latency and maximise performance for tightly coupled applications.
• Identify and resolve network bottlenecks, performance issues and potential risks to ensure a resilient and highly available environment.
• Conduct security hardening activities, including firewall, encryption and perimeter policy reviews, ensuring compliance with financial services security standards.
• Collaborate with infrastructure, network and migration teams to provide 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.
