Senior Engineer

Brief Role Objective:

As a Senior Platform & Infrastructure Engineer, you will be a senior member of a small Platform and Infrastructure Engineering team. You will remain hands-on, designing, building and operating secure, resilient and scalable platforms that enable development teams to deliver software safely, efficiently and reliably.

You will:

Take ownership of complex platform and infrastructure initiatives, from technical design and implementation through to operational handover.

Help establish and evolve pragmatic engineering standards, contributing to technical direction, peer review and continuous improvement across the team.

Lead the design, configuration and ongoing improvement of CI/CD pipelines, including build, test, deployment and release automation.

Define and evolve infrastructure-as-code standards and reusable Terraform patterns, promoting consistency, security and maintainability.

Develop, operate and improve the cloud and on-premise platform capabilities relied upon by development teams.

Champion DevOps and platform-engineering practices, fostering an automation-first, product-minded culture.

Work closely with the Platform & Infrastructure Team Head, Group teams and development teams to shape and deliver the UK cloud strategy.

Key Responsibilities:

Act as a senior, hands-on engineer within the Platform & Infrastructure team, providing technical leadership and contributing to the successful delivery of the team’s cloud, platform and infrastructure roadmap.

Design, build and operate a secure, resilient and scalable Azure infrastructure estate, including the associated CI/CD, infrastructure-as-code, container and observability capabilities that support application delivery.

Establish and evolve engineering standards, reference architectures, guardrails and reusable platform services, promoting consistency, automation, security, maintainability and operational excellence.

Lead the design and implementation of robust software and infrastructure delivery automation using GitLab, Kubernetes, Helm, Terraform and appropriate DevOps and platform-engineering practices.

Take ownership of complex technical designs, implementations and operational issues, managing risk and ensuring solutions are secure, supportable, cost-effective and transitioned effectively into operational service.

Partner with architects, development teams and Group technology colleagues to deliver cloud adoption and application-modernisation initiatives, including environment design, migration planning, deployment automation and operational readiness.

Embed security, resilience, compliance, monitoring and performance considerations throughout platform design and delivery, aligned with regulatory, Group and organisational requirements.

Contribute to technical review, knowledge sharing and team capability development; maintain high-quality architecture documentation, standards, runbooks and operational procedures.

Support effective platform service management, including incident and problem resolution, change planning, capacity and performance improvement, stakeholder communication, and evaluation of new technologies where they provide measurable value.

Essential Technical Requirements:

Proven experience in a senior platform, infrastructure or cloud engineering role, ideally within financial services or another highly regulated environment.

Strong hands-on experience designing, building and operating Microsoft Azure environments, including core compute, networking and storage services, with a sound understanding of identity, access management, network security, governance and cloud resilience.

Demonstrable experience designing and improving CI/CD pipelines using GitLab or comparable tooling, covering automated build, test, security assurance, deployment and release processes.

Strong practical experience with containerisation and orchestration, including Docker, Kubernetes and Helm, alongside an understanding of GitOps principles such as declarative configuration and controlled environment promotion.

Proven experience using Terraform to provision, configure and manage cloud and/or on-premise infrastructure, including the development of reusable, maintainable infrastructure-as-code patterns.

Experience implementing or operating monitoring, logging and observability capabilities using tools such as Splunk, Prometheus, Grafana or equivalent, with the ability to use operational data to improve reliability and performance.

Strong scripting and automation capability using PowerShell, Bash and/or similar languages, together with practical proficiency in at least one general-purpose language such as Python or Go. Able to write, maintain and review code used for automation, integrations, tooling and application support, with confident use of YAML for build, deployment and operational automation.

Experience working in Agile delivery environments, such as Scrum or Kanban, and with collaboration and delivery tooling including Jira and Confluence.

Strong communication and stakeholder-management skills, with the ability to collaborate effectively across distributed teams and communicate clearly with both technical and non-technical audiences.

Other skills, competencies and attributes:

Able to communicate complex technical concepts, decisions and risks clearly and appropriately to both technical and non-technical audiences.

Strong technical writing skills and attention to detail, with the ability to produce clear, accurate documentation including architecture diagrams, standards, runbooks, implementation guides and change records.

Proactive in documenting solutions, engineering standards and lessons learned to strengthen shared knowledge and support consistent delivery across the team.

Comfortable operating in a fast-paced and evolving environment, able to manage multiple priorities while maintaining sound judgement, quality and delivery focus.

A collaborative and constructive team member who shares expertise, welcomes challenge and feedback, and contributes positively to technical decision-making.

Well organised and dependable, with strong time-management skills and a consistent record of delivering against agreed commitments and deadlines
