Senior Linux Engineer

The Infrastructure Platform Engineering team designs builds and supports the Linux and cloud platforms that power critical business services across the organisation. We work closely with application security and architecture teams to deliver secure scalable and resilient infrastructure. Operating within Agile and DevSecOps ways of working the team focuses on automation standardisation and a cloud-first strategy. Our role is to balance innovation with the high reliability and compliance standards required in a regulated financial services environment.

As a Senior Engineer you will be a hands-on technical contributor responsible for building operating and continually improving Linux-based infrastructure platforms. You will apply strong engineering judgment to implement Infrastructure as Code automation and cloud-native practices. This role requires deep technical expertise the ability to resolve complex non-routine issues independently and close collaboration with delivery teams. You will exercise independent judgement on technical decisions and clearly communicate complex technical concepts to both technical and non-technical stakeholders while providing informal technical guidance to peers.
