DevOps & Site Reliability Engineer (SRE)

OpsHero is a boutique technology firm with an exclusive focus on DevOps services. We thrive on our non-traditional, flat structure which enables us to navigate away from the constraints of the corporate world. This allows us to maintain agility and adaptability, ensuring our ability to swiftly meet the evolving needs of our clients

At OpsHero, we are at the forefront of innovation, always incorporating cutting-edge technologies into our processes. We believe that by bridging the gap between development and operations, we can accelerate product delivery, enhance efficiency, and ultimately drive our client’s success.

What you will do

• Reliability ownership: Define and measure SLIs/SLOs, manage error budgets, and use them to guide release gates and risk decisions with product and engineering. 
• Observability, end to end: Instrument services and infra for metrics, logs, and traces; standardize dashboards/alerts; reduce noise and MTTR via runbooks and actionable paging.
• Automation & toil reduction: Build tools and guardrails (scripts, controllers, GitOps jobs) to eliminate repetitive ops work and improve stability.
• Incident response & postmortems: Lead on-call duties, triage issues, coordinate comms, and run blameless postmortems with clear, tracked actions. 
• Change management: Improve CI/CD reliability; enforce promotion checks aligned to SLOs/error-budget health.
• Architecture collaboration: Contribute to resilient designs with product and platform and engineering teams.
• Scope note: SREs collaborate closely with Platform/Infra; you influence infra changes and validate outcomes, while primarily owning reliability at the Service/Kubernetes layer (releases, configs, runtime policies, and telemetry).

What you will need

Kubernetes expertise

• Strong understanding of K8s architecture (API server, controllers, scheduler) and CRDs/Operators.
• Practical RBAC, admission controls, quotas/limits, and multi-tenant hardening.
• Networking: CNI, Ingress/Load Balancers, traffic policies; Autoscalers (HPA/VPA) and Cluster API exposure.
• Storage: CSI drivers; experience with cloud block/file (e.g., OpenStack Cinder) a plus.
• OpenShift experience is a plus.

Software development is a plus (Go preferred)

We use Go for ops tooling/operators; experience with client-go, controller-runtime, Operator SDK; comfortable with REST/gRPC and auth patterns; event-driven reconciliation.

Infrastructure & DevOps

• Solid Linux admin/debugging, containers, and networking fundamentals.
• GitOps mindset (e.g., Argo CD) and CI/CD experience; strong versioning/rollback discipline.
• Understanding of distributed systems (etcd basics, leader election) and failure modes.

Nice to have

• CKA/CKAD/CKS or CNCF certifications (KCNA/CCA).
• Contributions to open source (operators, controllers, CRDs).
• Experience with OpenTelemetry, Prometheus/Alertmanager, Loki, Grafana, and SLO-based alerting. 
• OpenStack experience
