Define and deliver DevOps strategies supporting POS platforms, Terminal Management Systems (TMS), and Terminal Configuration Systems (TCS) -
Translate product roadmaps and technical requirements into CI/CD pipelines, deployment models, and operational execution plans.
Design, build, and continuously enhance CI/CD pipelines for backend services and terminal software using tools such as Jenkins, GitLab CI, GitHub Actions, or equivalent.
Embed security controls into delivery pipelines, including SAST (Fortify), SCA, and DAST, enabling strong shift-left security practices.
Implement secure secrets and key management, covering key lifecycle controls, HSM integration, and cryptographic interface handling.
Ensure platform deployments meet regulatory, audit, and PCI governance requirements.
Build and operate Infrastructure as Code using Terraform, and manage containerised platforms with Kubernetes and Helm.
Provision and maintain development, test, and production environments, ensuring stability and consistency across all stages.
Govern configuration management and secure handling of environment-specific settings.
Design and execute release strategies for terminal ecosystems, including blue/green, canary, and phased deployments.
Manage artefact repositories such as Nexus or Artifactory, supporting controlled, auditable releases.
Establish observability through monitoring, logging, and tracing using tools including Splunk, Dynatrace, Prometheus, and Grafana.
Define SLIs and SLOs, lead incident response, and drive post-incident reviews and continuous improvement.
Lead performance tuning, capacity planning, and cost optimisation initiatives across cloud or cloud-native environments.
Embed automated testing (unit, integration, contract, end-to-end) into CI/CD pipelines and support device-farm or emulator-based testing for terminal images.
Collaborate closely with platform, security, product, QA, Android/terminal engineering, and operations teams to ensure release readiness and environment stability.
Provide clear technical updates, risk assessments, and delivery status to programme and senior stakeholders.
Experience
Proven hands-on experience in DevOps, SRE, or platform engineering roles within large-scale enterprise environments, ideally in payments, fintech, or POS domains.
Strong background in designing and operating modern CI/CD pipelines and automation frameworks.
Practical experience integrating security tooling such as Fortify, SCA, and DAST into regulated delivery environments.
Advanced expertise with Terraform, Docker, Kubernetes, and container-based deployment architectures.
Experience designing and supporting backend systems common to payment ecosystems, including:
Java, Kotlin, Spring, and microservices-based architectures
RESTful APIs
Kafka or other message bus technologies
Relational and NoSQL data stores
Strong scripting and automation skills using Python, Bash, Groovy, or comparable languages.
