ABOUT THIS OPPORTUNITY 

We’re investing heavily in the resilience, performance and modernisation of the Financial Wellbeing Platform and we’re looking for an experienced Technical Application Support Specialist to help us deliver brilliant, reliable service for our customers. 

In this hands-on role, you’ll be working across a variety of technologies to support live service, drive operational excellence, and contribute to continual improvement across the platform. You’ll work closely with engineering teams on and offshore, influence backlog priorities, help prevent repeat incidents, and support change delivery in a complex, fast-paced environment. 

This is a fantastic opportunity for someone who thrives in a production-focused environment, enjoys problem solving, and brings real, practical experience across application support tooling, performance tuning, and service management. 

In addition, the team is responsible for maintaining 24/7 support for the platform. While we operate a rota to ensure reliable out of hours coverage, participation in the oncall schedule is optional for this role and available to colleagues who wish to take part. 

DAY TO DAY, YOU WILL: 

• Support incident, problem and change delivery processes across the Financial Wellbeing Platform

• Adaptable — able to work effectively in different teams, labs and delivery models 

• Continuous learner with curiosity and appetite to grow 

• Analytical mindset, able to interpret incident data, identify patterns, and propose improvements 

• Organisational awareness and ability to navigate complex operational structures 

IT WOULD BE GREAT IF YOU HAD:

WHAT YOU’LL GET IN RETURN

You’ll also receive: 

• A performance-based share bonus 

• A generous pension contribution
