About the Role
We are looking for a Senior Systems / Reliability Engineer to act as a technical anchor within our IT Operations function. This is an environment where AWS-first cloud evolution meets critical legacy and physical infrastructure.
This is not a “migration to cloud” role or a "move fast and break things" developer position. Instead, we need a seasoned operator who thrives on stability, resilience, and risk reduction. You will join us as a technical peer to our existing Senior Engineer, focusing the first six months on understanding our estate, documenting architecture, and maturing our production environment. This is a 100% remote role suited for someone with exceptional technical judgment who enjoys owning outcomes end-to-end.
Key Responsibilities
Operational Stability & Reliability: Own the health and performance of our hybrid (AWS/On-prem) estate. Your primary goal is to reduce technical debt and remove operational toil through sound engineering practices.
Infrastructure Maturation: Lead the effort to document our environment—creating the architecture diagrams and runbooks necessary to eliminate single points of failure.
Pragmatic Kubernetes Management: Operate and improve our existing production Kubernetes clusters. You will help ensure K8s is used consistently and reliably, making pragmatic decisions on where it adds the most value.
Technical Authority & Peer Leadership: Serve as a senior technical sounding board and mentor. You will influence architecture, tooling, and optimization decisions, providing recommendations backed by operational data.
Developer Enablement: Partner with development teams to provide the automation, standards, and guardrails that allow them to own their own deployments safely.
Sustainable On-Call: Participate in a sustainable on-call rotation. As a senior escalation point, you will drive root-cause analysis to ensure alerts remain at a minimum and the system stays resilient.
Security & Compliance Support: Own the operational application of ISO 27001 controls within your remit. You will work closely with our Security Manager to provide audit evidence and maintain high operational standards.
Requirements
Must Have:
5+ years in a Senior SysOps, DevOps, or SRE role with proven experience managing high-pressure production environments.
Strong Linux Administration: Confident troubleshooting of production issues (services, logs, performance, and networking). You should have sound judgment on OS vs. application/platform problems.
Hybrid Infrastructure Experience: Practical knowledge of AWS (primary) and Azure, with a comfort level managing both cloud-native and physical/legacy infrastructure.
Automation & IaC: Proficiency with Terraform and configuration management (e.g., Ansible).
Kubernetes Competency: Experience operating and improving Kubernetes in a production setting.
Reliability Mindset: A track record of identifying risks and fixing root causes to improve system monitoring and quality.
Desirable:
Familiarity with physical data center environments or Cisco networking.
Experience in regulated environments (Healthcare, Finance, or similar).
Experience supporting ISO 27001 or SOC2 audits.
