Job description
The Senior DevOps Engineer works with the team to lift the visibility, reliability, and security of the platforms that serve our clients and end-users globally. We are a focused team so your judgment materially shapes how the platform runs. The role owns:
- Reliability and uptime of Esyasoft's production estate on AWS and Kubernetes
- CI/CD pipeline ownership — finalizing the move to full automation via Git. Ops
- Observability, security and compliance posture across the platform
- On-call coverage and incident response as part of a paid weekly rotation Key Responsibilities & Areas of Ownership A. Cloud Infrastructure and Platform Operations
- Own day-to-day reliability of Esyasoft's production estate on AWS and Kubernetes, including incident triage and remediation
- Operate and harden the Linux server fleet (Rocky Linux, Amazon Linux) and supporting database layers
- Manage cloud cost and capacity in partnership with engineering — right-size, decommission and forecast B. CI/CD and Infrastructure as Code
- Finalise the transition to a fully automated CI/CD pipeline (Jenkins to Git. Ops via FluxCD)
- Maintain and extend Infrastructure as Code using Terraform and Kustomize
- Curate the developer experience so engineers can ship safely, quickly, and with minimal friction C. Observability, Monitoring and Incident Response
- Evolve the monitoring stack (Prometheus, Grafana) — dashboards, alerts and SLOs that earn their keep
- Lead incident response during your rotation; drive blameless post-mortems and follow-through actions
- Participate in the weekly paid on-call rotation to maintain service levels for Esyasoft's users D. Security and Compliance
- Maintain Esyasoft's posture against Cyber Essentials, ISO 27001 and PCI-DSS
- Embed secure-by-default patterns in CI/CD, IaC, container images and Kubernetes manifests; partner on access reviews and secrets management E. Engineering Practice and Team Contribution
- Mentor peers and product engineers on infrastructure, deployment and reliability practice
- Contribute to architectural decisions across the wider engineering team F. Tooling and Continuous Improvement
- Evaluate emerging tools and patterns responsibly — prove value, then adopt; keep what we have working hard before reaching for the new
- Curate documentation and runbooks so platform knowledge is shared across the team, not siloed Requirements Required Skills & Experience
- Proven track record running production workloads on AWS, with hands-on experience operating Kubernetes in production (not just deploying to it)
- Strong foundations in core systems — Linux, HTTP, networking, Bash and a scripting language (Python preferred)
- Practical experience with Infrastructure as Code (Terraform preferred), Git. Ops tooling and CI/CD pipelines end-to-end
- Comfort participating in an on-call rotation and leading incident response, including blameless post-mortems Desirable Skills & Experience
- Exposure to compliance frameworks — Cyber Essentials, ISO 27001 or PCI-DSS — in a production context
- Experience with additional cloud providers (Digital Ocean, GCP) and database operations at scale (MySQL)
- PHP exposure (Esyasoft's stack includes PHP services) Key Attributes
- Pragmatic — picks the smallest change that solves the real problem; values clarity over cleverness
- Reliability-minded — instinctively asks 'what does this look like when it breaks?' before shipping
- Clear communicator — writes runbooks, explains incidents and pushes back without drama Use of Technologies Esyasoft operates primarily within the cloud-native ecosystem and includes the requirement to work as a competent user of:
- AWS, Kubernetes, Docker
- Terraform, Kustomize, FluxCD, Jenkins, Prometheus, Grafana, MySQL
- Python, Bash, PHP — running on Rocky Linux / Amazon Linux This role may also require flexibility to work with additional cloud providers (Digital Ocean, GCP) and third-party tools as the platform evolves.
