Senior DevOps & Environments Engineer

The Senior DevOps & Environments Engineer will join a team responsible for the reliability, automation, provisioning, configuration, and continuous improvement of environments supporting the full software development lifecycle. The role is critical in ensuring that non-production environments are stable, performant, and aligned with the needs of engineering, QA, and release teams. Working across 30+ applications, this engineer will help modernise the environment landscape through Infrastructure-as-Code, improved observability, and SRE-aligned operational practices to enable faster, safer, and higher-quality delivery. Responsibilities:

• Design, implement, and maintain Infrastructure-as-Code (IaC) for consistent and repeatable provisioning of development and test environments, primarily using Terraform.
• Lead technical investigations and act as the escalation point for environment-related incidents, outages, configuration issues, and service degradation across non-production platforms.
• Collaborate closely with development, QA, and platform teams to deliver scalable, automated, and resilient environment solutions.
• Analyse and optimise performance of non-production systems, identifying and resolving environment bottlenecks.
• Maintain environment fidelity and integrity through controlled configuration management, patching, visioning, and rollback strategies.
• Support release and deployment planning, ensuring environment readiness, dependency alignment, and overall stability during release cycles.
• Implement and maintain monitoring, observability, and logging frameworks, with a strong emphasis on Dynatrace and CNCF-aligned tooling.
• Define meaningful, proactive alerting policies that reduce noise, highlight real issues, and accelerate response times.
• Apply SRE principles such as SLIs/SLOs, automated remediation, and continuous feedback loops to improve environment uptime and reliability.
• Mentor junior engineers, share best practices, and contribute to knowledge bases, documentation, and process maturity.
• Support Disaster Recovery (DR) testing, validating end-to-end system recovery, integration behaviour, and service resilience during failover scenarios.
• Champion automation and operational excellence, reducing manual effort and increasing the team's ability to deliver environments at scale., As a Disability Confident Committed Employer we have committed to:

• Expertise in Terraform and experience defining an organisation-wide IaC strategy.
• Proficient in scripting and automation (Python, Bash, PowerShell).
• Strong communication, documentation, and collaborative problem-solving skills.

Experience:

• Hands-on experience with on-premise infrastructure, virtualisation, containerisation, and exposure to cloud platforms such as AWS or Azure.
• Understanding of performance engineering, including load testing frameworks and performance analysis.
• Experience supporting QA, development, and release management teams with reliable, well-controlled non-prod environments.
• Ability to troubleshoot complex multi-layered issues across infrastructure, networks, applications, middleware, and databases.
• Familiarity with SRE principles and modern operational practices such as postmortems, runbooks, SLIs/SLOs, error budgets, and automated recovery patterns.
• Experience with APM and observability tooling, ideally Dynatrace, including metrics, traces, dashboards, and alerting configuration.
