DevSecOps Engineer

Key Responsibilities:Infrastructure & Cloud Management: Design, implement, and maintain cloud infrastructure on AWS using Infrastructure as Code principles. Manage containerised applications using Amazon EKS and ensure optimal performance, security, and cost efficiency. Collaborate with development teams to architect scalable solutions that meet both functional and non-functional requirements whilst embedding observability from the ground up.Security Controls Implementation Implement and maintain security controls throughout the development lifecycle, from code commit to production deployment. Integrate automated security testing, static and dynamic code analysis, and vulnerability scanning into CI/CD pipelines. Establish security gates and approval processes that prevent vulnerable code from reaching production environments. Develop and enforce security policies for container images, infrastructure configurations, and application deployments with comprehensive security observability.Advanced Monitoring & Observability Design and implement enterprise-grade observability solutions using ELK Stack or Prometheus-Grafana to provide comprehensive insights into system performance, security events, and operational health. Architect distributed tracing solutions using Open Telemetry to monitor application performance across complex microservices architectures and troubleshoot issues with precision. Create sophisticated dashboards, alerts, and reportingmechanisms that provide actionable insights to stakeholders whilst ensuring security events, performance anomalies, and operational issues are proactively identified and investigated. Implement observability-driven incident response and post-mortem processes.CI/CD Pipeline Management Build, maintain, and optimise CI/CD pipelines using GitLab Runners to enable rapid, reliable, and secure software delivery. Embed security controls and observability instrumentation at every stage of the pipeline including pre- commit hooks, automated security testing, compliance checks, and deployment validation. Implement automated testing, security scanning, and deploymentprocesses that support continuous integration and deployment practices whilst maintaining zero-trust security principles and comprehensive pipeline observability.Infrastructure as Code & Policy as Code Implementation Leverage Infrastructure as Code tools, particularly Terraform, to automate infrastructure provisioning and management with built-in security controls, compliance checks, and observability instrumentation. Implement Policy as Code frameworks to codify governance, compliance, and security policies that are automatically enforced across all infrastructure deployments. Develop custom automation scripts and tools tostreamline operational processes whilst ensuring security standards and observability requirements are maintained. Integrate and utilise GenAI-based coding agents to enhance development productivity and code quality, implementing appropriate security guardrails and observability for AI-assisted development.Observability Strategy & Implementation Develop and execute comprehensive observability strategies that encompass metrics, logs, traces, and events across the entire application and infrastructure stack. Implement service level objectives (SLOs)and service level indicators (SLIs) to measure and improve system reliability. Design and maintain observability platforms that support real-time monitoring, historical analysis, and predictive insights for both operational and security use cases.Essential Requirements:Technical Skills• Extensive experience with AWS cloud services and architecture patterns• Strong proficiency in Terraform for Infrastructure as Code implementation, including advanced features such as modules, workspaces, and state management• Deep hands-on experience with ELK Stack (Elasticsearch, Logstash, Kibana) or Grafana for monitoring, visualisation, and observability• Strong knowledge of Amazon EKS and container orchestration with observability best practices• Advanced experience implementing observability solutions and distributed tracing with OpenTelemetry across complex distributed systems• Proficiency with GitLab or GitHub for version control and CI/CD pipeline management• Experience with GenAI-based coding agents and AI-assisted development tools Observability Expertise• Proven experience designing and implementing comprehensive observability strategies for large-scale distributed systems• Deep understanding of the three pillars of observability: metrics, logs, and traces, and their integration• Experience with observability tools such as Prometheus, Splunk, or commercial APM solutions• Knowledge of observability data correlation, anomaly detection, and automated alerting strategies• Understanding of observability-driven development and operational practices Security & Compliance• Strong understanding of DevSecOps principles and implementing security controls throughout the development lifecycle using Infrastructure as Code and Policy as Code methodologies• Experience with security scanning tools, SAST/DAST solutions, and vulnerability management integrated into IaC workflows and automated through policy enforcement• Knowledge of compliance frameworks, security standards, and regulatory requirements codified and enforced through Policy as Code implementations• Understanding of network security, identity and access management, and data protection defined and managed through Infrastructure as Code templates and policy definitions• Experience with security orchestration and incident response procedures automated and standardised through Infrastructure as Code and Policy as Code frameworksProfessional Experience• Minimum 5 years of experience in DevOps, SRE, or similar roles with security and observability focus• Minimum 2 years of hands-on Terraform experience in production environments• Proven track record of implementing and managing secure cloud infrastructure at scale with comprehensive observability• Experience working in agile development environments with security integration and observability practices• Strong problem-solving skills and ability to work under pressure whilst maintaining security standards and observability requirements Preferred Qualifications• AWS certifications (Solutions Architect, DevOps Engineer, or Security Specialty)• HashiCorp Certified: Terraform Associate or Professional certification• Observability and monitoring certifications or demonstrable experience• Experience with Terraform Enterprise or Terraform Cloud• Experience with additional monitoring tools, APM solutions, and observability platforms• Experience with policy-as-code and governance automation using tools like Sentinel or Open Policy Agent• Background in software development with understanding of secure coding practices and observability instrumentation
