Senior DevOps & Environments Engineer

Expleo • Full-time • London, ENG • 2d ago

Overview

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.

Essential skills

Strong knowledge of VMware, vSphere, virtualisation platforms, and on‑premise infrastructure management.
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.
