Job Overview

Aquis Exchange is seeking a highly capable Cloud & DevOps Engineer to help shape, optimise, and scale our infrastructure. This role is ideal for someone who is deeply passionate about automation, efficiency, and building resilient systems. You’ll join a small, expert DevOps team working across low-latency trading platforms, cloud environments, and on-prem systems—contributing to both strategic projects and hands-on engineering.

We are looking for someone who brings a strong sense of curiosity, excels in technical problem-solving, and is committed to designing systems that are robust, reproducible, and thoughtfully engineered. The ideal candidate naturally seeks to refine processes, explore emerging technologies, and deliver reliable, high-quality solutions that contribute to the continual improvement of our platform.

Responsibilities and Duties

• Build and automate hybrid infrastructure using Infrastructure-as-Code (Terraform), with a primary focus on container platforms and Kubernetes/OpenShift environments.
• Continuously improve automation across containerised, on-prem, and cloud environments using Ansible, Python, and supporting tooling.
• Collaborate with Development and Infrastructure teams to productionise new technologies and workflows, with particular emphasis on container-native and GitOps patterns.
• Champion and help steer architectural decisions with an emphasis on container orchestration, automation, reliability, and operational excellence.
• Support internal teams with build pipelines, CI/CD systems, OpenShift/Kubernetes workloads, and developer tooling.
• Assist Linux engineering with deployment, configuration management, and systems operations at scale across containerised and virtualised environments.
• Lead capacity planning and ensure container platforms and supporting environments remain scalable across Dev, QA, Test, and Production.
• Maintain clear, current, and high-quality documentation of systems and processes.

Required Skills/Experience

• Significant experience at a senior level designing, implementing, and operating Kubernetes and OpenShift platforms, ideally across hybrid on-prem and multi-cloud environments (AWS, GCP, or similar).
• Advanced DevOps experience including CI/CD, GitOps workflows, container image management, monitoring, and automation.
• Strong Linux system administration (RedHat/CentOS or similar), including experience underpinning OpenShift deployments.
• Demonstrable and extensive scripting/automation experience: Terraform, Python, Bash, Ansible.
• Strong experience with Git, GitLab, and container-native deployment pipelines (Helm, ArgoCD, or similar).
• Strong understanding of core networking concepts (TCP/IP, routing, DNS, load balancing, firewalls, VPNs, and container networking/service mesh).
• Proven, hands-on experience with containers and orchestration (Docker, Kubernetes, OpenShift); familiarity with cloud-managed equivalents (ECS/ECR, GKE) is a plus.
• Knowledge of infrastructure design patterns, automation best practices, and configuration management principles in containerised environments.
• Database familiarity (MySQL, QuestDB, Elasticsearch).
• Strong communication skills — clear, detailed, and pragmatic.
