Application Upgrade and Automation Engineer
SC Cleared - 6 month contract - Hybrid - London 50%
Our Financial Services client is seeking three Application & Platform Upgrade Engineers to join their Financial Systems and Solutions division. These roles will focus on upgrading enterprise applications across the estate and helping design future upgrade paths and strategies.
The successful candidates will bring hands-on experience upgrading applications across a range of technologies in Windows and Linux environments, ideally gained in other large-scale organisations. Strong automation skills are essential, as the team is building tooling to streamline and standardise application and infrastructure upgrades going forward.
These roles work closely with both application and infrastructure teams across the Bank, so clear, confident communication is important — you'll need to translate technical detail for different audiences and keep stakeholders informed throughout delivery.
Reasons to use Rodeo

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
