The ideal candidate will bring strong experience across platform engineering, cloud technologies, automation, and software development, with a passion for improving developer experience and enabling high-performing engineering teams through scalable platform solutions.

Key Responsibilities

• Design, build, and maintain internal developer platforms used by multiple engineering teams, with a focus on reliability, security, scalability, and developer experience.
• Own and evolve the central engineering toolchain including GitHub Enterprise, GitHub Cloud, GitHub Actions, GitHub Copilot, and GitHub-hosted runners.
• Develop and maintain Infrastructure as Code (IaC) solutions for Google Cloud Platform using Terraform and related tools.
• Build automation and platform tooling using Python or Java to streamline environment provisioning, configuration management, CI/CD pipelines, and operational processes.
• Design, implement, and standardise CI/CD pipelines using GitHub Actions for build, testing, security scanning, release management, and deployment activities.
• Collaborate with security, risk, architecture, and engineering teams to embed secure-by-default patterns, policy as code, secrets management, and compliance controls into the platform.
• Support onboarding of development teams onto shared platform capabilities and engineering standards.
• Monitor platform performance, reliability, availability, and operational costs, implementing proactive improvements and optimisation initiatives.
• Implement and maintain observability capabilities including logging, monitoring, metrics, tracing, alerting, and operational dashboards.
• Provide technical leadership and subject matter expertise to application teams, supporting troubleshooting, architectural decisions, and adoption of platform capabilities.
• Contribute to platform roadmaps, backlog management, engineering standards, and continuous improvement initiatives.
• Support cloud-native application delivery across containerised and Kubernetes-based environments.
• Maintain platform documentation, engineering standards, operational procedures, and reference architectures.

What You'll Need

• Experience in Platform Engineering, Software Engineering, DevOps Engineering, Site Reliability Engineering (SRE), or a similar role.
• Strong programming skills in Python or Java, including the development of automation tools, platform services, microservices, and engineering utilities.
• Hands-on experience designing, building, and supporting Google Cloud Platform (GCP) environments.
• Strong experience with Infrastructure as Code using Terraform, Ansible, or similar automation frameworks.
• Proven experience developing reusable IaC modules, enforcing engineering standards, and integrating infrastructure provisioning into CI/CD pipelines.
• Hands-on experience with GitHub Enterprise or GitHub Cloud, including GitHub Actions, reusable workflows, repository management, and developer enablement initiatives.
• Experience implementing and supporting enterprise CI/CD platforms and modern software delivery practices.
• Strong understanding of DevOps and SRE principles including automation, continuous delivery, reliability engineering, incident management, observability, and operational excellence.
• Experience working within shared platform engineering or developer productivity teams supporting multiple delivery squads.
• Strong understanding of cloud-native architectures, platform design principles, and engineering best practices.
• Experience with containerisation and orchestration technologies including Docker, Kubernetes, and Google Kubernetes Engine (GKE).
• Knowledge of cloud security, identity and access management, secrets management, encryption, governance, and compliance controls.
• Excellent communication, stakeholder engagement, problem-solving, and collaboration skills.
• Experience supporting banking, financial services, or other highly regulated environments is highly desirable.

Desirable Skills

• Experience with GitHub Copilot implementation, governance, and developer productivity initiatives.
• Experience developing platform engineering frameworks and self-service developer capabilities.
• Knowledge of Policy as Code, Open Policy Agent (OPA), Sentinel, or similar governance frameworks.
• Experience with monitoring and observability platforms such as Datadog, Grafana, Prometheus, Cloud Monitoring, or Splunk.
• Experience with cloud cost optimisation, FinOps practices, and workload management strategies.
• Knowledge of security, risk, and compliance requirements within banking or regulated financial services environments.
• Experience supporting enterprise-scale cloud transformation and platform modernisation programs.
• Understanding of architecture governance, technology standards, and engineering operating models.

Why Join Us?

• Work on large-scale platform engineering initiatives supporting enterprise-critical banking services.
• Play a key role in shaping the future developer experience across multiple engineering teams.
• Gain exposure to modern platform engineering, cloud-native technologies, GitHub Enterprise, and Google Cloud Platform.
