We’re embarking on one of the most ambitious technology transformations in our history: migrating our core on-premises datacentre workloads to AWS, embedding Infrastructure as Code (Terraform), and automating delivery through modern GitHub CI/CD pipelines.\nAs a Senior Infrastructure Engineer, you won’t just be keeping the lights on. You’ll be at the forefront of this shift helping architect, modernise, and operationalise a modern, cloud-first estate that powers millions of customer transactions.\nThis is a hands-on, high-impact role. You’ll lead the design and delivery of critical cloud and hybrid infrastructure, establish modern engineering standards, and mentor engineers across the team. If you thrive on turning traditional enterprise environments into lean, automated, and resilient platforms, this is your chance to leave a lasting mark.\nWhat you'll do\nOwn technical design, delivery and support for medium-sized infrastructure changes and projects. \nUnderstand dependencies between infrastructure technologies, applications, networks, identity, security and operational processes. You’ll proactively monitor, plan and remediate performance and capacity issues. \nTroubleshoot complex technical issues and implement preventative measures to stop incidents from reoccurring. \nAdhere to engineering standards, change control, service management processes, and project governance (PRINCE2). \nElevate team capability by leading design and peer reviews, and actively coaching less experienced engineers. \nCommunicate effectively to technical and non-technical audiences, explaining technical risks, decisions and trade-offs clearly. \nEffectively manage your workload, managing competing priorities and ensuring work is delivered within agreed timescales. \nBuild strong relationships with third-party suppliers while maintaining accurate asset lists and manage hardware and software renewals. \nOperate within an Agile team, actively contributing to sprint planning, effort estimation, and retrospectives to drive continuous improvement. \nTechnical knowledge\nWe're looking for broad infrastructure expertise across a range of technologies. Experience with the following will be valuable.\nCore Technical Knowledge\nCloud infrastructure (preference of AWS)\nInfrastructure as Code (Terraform), automation, and scripting\nCI/CD pipelines (GitHub, BitBucket, Jenkins)\nContainers and orchestration (Kubernetes, EKS, TKG)\nMonitoring and observability tooling (Grafana, Prometheus, OpsGenie, SolarWinds)\nWindows Server and Red Hat Enterprise Linux server configuration and management\nDesirable Technical Knowledge\nFortinet networking (FortiGate, FortiManager, FortiAnalzyer, SD-WAN)\nCisco networking (Catalyst and Nexus, ISE, Catalyst Centre, BGP, OSPF) or equivalent demonstrable networking experience\nEnterprise storage, backup and disaster recovery technologies (Netapp ONTAP, FSx, Dell Data Domain, PowerProtect) and recovery testing concepts (runbook creation, simulated failover testing) \nVMWare technologies including Dell VxRail HCI (VCF, VMC, NSX, HCX, vSAN, Aria Suite)\nFamiliarity with security tooling and practices including patch and vulnerability management, zero-trust architecture, and Privileged Access Management (PAM).\nHow you'll work\nTechnical expertise is important, but so is the way you apply it. You'll bring:\nThe ability to work through complexity and ambiguity, gathering the information and perspectives needed to make sound decisions.\nGood judgement, ownership and self-awareness when balancing business needs, risk, security and operational impact.\nA customer-focused mindset, understanding how reliable infrastructure supports service quality and the customer experience.\nAn appreciation of how Infrastructure connects with wider Technology Services teams and business outcomes.\nClear communication, constructive challenge, useful feedback and a willingness to share knowledge.\nA considered approach to technical decisions, weighing evidence, available options and long-term maintainability.\nA collaborative approach to improving services, reducing operational risk and supporting lasting change.\nThe ability to build strong working relationships across Technology Services and the wider business.\nAbout AJ Bell\nAt AJ Bell, we believe investing should feel good.
