Principal Software Engineer - DevOps

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 GitOps

• 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 GitOps 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), GitOps 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.
