About this opportunity

Lloyds Banking Group is the UK’s largest Digital, Retail, and Commercial bank. It is committed to helping Britain prosper. The group is investing £3bn to transform its products and platforms and become the bank of the future.

With 789 software systems and 26,000 servers we’re servicing 80,000 colleagues, 30m+ customers, and over 14m+ online users you can be confident our IT professionals have sizeable and exciting challenges every single day.

In this role, you’ll deliver highly advanced and sophisticated technical support for mainframe Db2 and its associated processes, tools, and utilities. You’ll help run and maintain services according to Group standards and policies (and to agreed service levels) and will assist with the delivery of investment funded work within mainframe environments - this includes out of hours.

Additionally, you’ll provide technical support (including incident and problem resolution for systems and processes in complex environments) – again this includes out of hours support.

What you’ll do 

• Provide support for complex mainframe environments to tight timescales.

• Help drive the strategy and design across the mainframe development and test estate.

• Own and drive the zDBA technology roadmap, and work closely with stakeholders to deliver against it.

• Implement standardisation and drive improvement initiatives in the team.

• Work collaboratively across the wider Lab and Platform teams to develop, promote, and implement process initiatives.

• Ensure processes, governance, and procedures are rigorously adhered to.

Why Lloyds Banking Group

We’re on an exciting journey to transform our Group and the way we’re shaping finance for good. We’re focusing on the future, investing in our technologies, workplaces, and colleagues to make our Group a great place for everyone. Including you!

What you’ll need

• Extensive in-depth expertise and knowledge of Db2 on z/OS.  

• Expert-level experience of performance monitoring and optimisation of Db2, including SQL tuning, buffer pool tuning, with the ability to make targeted recommendations to improve service stability and availability. 

• Expert-level experience of governing and approving DDL changes, handling schema evolution, validating impact, and ensuring alignment to change‑control processes.

• Extensive experience of leading the resolution and troubleshooting of critical on-line systems. 

• Proven experience of communicating and translating complex technical concepts for Senior Leadership.

• Experience of supporting junior team members, providing coaching on Db2 fundamentals, performance tuning, utilities, and operational processes.

It would be great if you also had

• 10+ years of experience as a z/OS Db2 DBA in a financial organisation.

Our continued commitment to helping Britain prosper means that as a colleague you can make a difference to customers, businesses and communities.

Together we have a key role to play in shaping the bank of the future, whilst the scale and reach of our Group means you'll continue to have opportunities to learn, grow and develop.

We're focused on creating a values-led culture, and our approach to inclusion and diversity means that we all have the opportunity to make a real difference, together.

As part of the Group's commitments as a result of ring-fencing legislation, colleagues based in the Crown Dependencies are required to be exclusively dedicated to the non-ring-fenced bank and its subsidiaries. This means that colleagues who are based in the Crown Dependencies would not be able to undertake roles for the Ring Fenced Bank from their existing location and would need to consider relocation when applying for roles.

At Lloyds Banking Group, we're driven by a clear purpose; to help Britain prosper. Across the Group, our colleagues are focused on making a difference to customers, businesses and communities. With us you'll have a key role to play in shaping the financial services of the future, whilst the scale and reach of our Group means you'll have many opportunities to learn, grow and develop.

We keep your data safe. So, we'll only ever ask you to provide confidential or sensitive information once you have formally been invited along to an interview or accepted a verbal offer to join us which is when we run our background checks.  We'll always explain what we need and why, with any request coming from a trusted Lloyds Banking Group person. 

We're focused on creating a values-led culture and are committed to building a workforce which reflects the diversity of the customers and communities we serve. Together we’re building a truly inclusive workplace where all of our colleagues have the opportunity to make a real difference.
