Required Skills & Experience

• 12+ years in software/infrastructure engineering, with at least 5 years in a senior DevOps, SRE, or platform engineering role owning production CI/CD for a multi-team estate
• Deep, hands-on Kubernetes and Helm — authoring charts, debugging workloads in production, managing multi-environment and multi-region deployments (OpenShift experience strongly preferred)
• Expert container tooling — Docker, multi-stage builds, image hardening, private registry management
• Cross-stack build expertise — Maven and Gradle (Java 17/21), npm/Nx (Node 22+), Python packaging (uv/pip, FastAPI services); able to diagnose a broken build in any stack
• Pipeline-as-code — Tekton-style declarative pipelines, Harness, Jenkins, GitHub Actions or GitLab CI, including reusable template design
• Infrastructure as code and configuration management — Ansible and/or Terraform at production scale
• Strong scripting and automation in Python and Bash; comfortable writing production-grade operational tooling
• Artifact management and dependency governance — Artifactory/Nexus, SonarQube, SAST/SCA, image scanning
• Observability in production — AppDynamics/Dynatrace, Prometheus/Grafana, centralised logging; on-call and incident command experience
• Secrets and identity — CyberArk/Vault, OAuth2/JWT service-to-service authentication, certificate and TLS lifecycle management
• Data platform operational exposure — Kafka, Spark, Airflow, and at least one distributed query/lakehouse technology (Starburst/Trino, Iceberg, or equivalent)
• Proven legacy pipeline migration — track record of modernising delivery pipelines without disrupting release cadence
• Excellent written communication — able to set standards that other teams willingly adopt and sustain

Desired Skills & Experience

• Financial services or regulated-industry experience — familiarity with change management, segregation of duties, audit evidence, and regulatory reporting platforms
• GenAI/LLM production operations — RAG pipelines, vector stores (pgvector, Chroma), agent frameworks, MCP servers, model gateway integration, token cost and latency management
• FinOps / cloud and on-premises cost optimisation
• Frontend delivery familiarity — Angular/Nx monorepos, Module Federation, design-system distribution
• Chaos engineering, DR and resiliency testing; performance and load engineering
• Certifications: CKA/CKAD, AWS/GCP/Azure professional-level, RHCE

What you'll be doing:

• CI/CD Standardisation

• Own and evolve shared pipeline templates (pipeline.yaml tasks for Maven, Gradle, npm/Nx, Python, container image build, and Helm chart publish)

• Consolidate legacy Jenkins/Harness pipelines onto the strategic declarative platform

• Drive build times, flakiness rates, and pipeline success rates as tracked operational metrics

• Kubernetes & Release Engineering

• Maintain Helm chart and values conventions across dev/SIT/UAT/prod and multiple data centres

• Standardise probes, resource sizing, autoscaling, config/secret injection, and rollback procedures

• Own promotion paths and zero-downtime release patterns on OpenShift/ECS and EKS

• Infrastructure as Code

• Ansible for the Airflow/VM estate; Terraform-style declarative provisioning where applicable

• Deliver reproducible developer environments and eliminate snowflake configurations and manual runbook dependencies

• Build & Dependency Governance

• Manage Artifactory repository policy, JDK 17/21 and Node 22/24 toolchain currency, and the shared Gradle dependency BOM

• Drive Renovate rollout and remediation of vulnerable or EOL dependencies across all 70+ repositories

• Observability & Reliability

• Own AppDynamics, Prometheus/Grafana, and log aggregation standards across the platform

• Define SLOs, alerting rules, capacity and cost visibility frameworks

• Lead production incident response, RCA, and permanent-fix follow-through for platform-level failures

• Security & Controls Automation

• Externalise secrets from code into CyberArk/Vault; enforce SonarQube quality gates and secure-coding checks in pipeline

• Own image hardening, scanning, and audit evidence generation for regulatory review and compliance

• Data & AI Platform Enablement

• Own deployment, scaling, and operational support for Spark batch, Iceberg/Starburst, Airflow, and JupyterHub

• Support GenAI/RAG service operations — including GPU/model gateway access patterns, vector store operations, agent-service scaling, and token cost/latency management

• Developer Experience

• Build and maintain golden-path templates for new services across all supported stacks

• Ensure local build parity with CI; maintain platform documentation so teams self-serve rather than raise tickets

• Technical Leadership

• Mentor engineers across the ERM programme; conduct design reviews and set engineering manifesto standards

• Champion branch hygiene, PR etiquette, green builds, and SonarQube compliance across the estate

• Represent the platform engineering function in architecture forums, risk governance, and regulatory audit engagements
