Job Description: 

We’re looking for a DevOps Engineer to partner with our platform architect on the infrastructure, CI/CD, and deploy automation behind our products. Our deploy plane runs on Kubernetes with parameterized Helm charts per product environment and Argo CD GitOps from a platform repo. Builds, tests, and image pushes run in our CI/CD platform; deploys land as values-file commits that Argo CD reconciles. Workloads run on AWS EC2 nodes today, with managed PostgreSQL, object storage, a self-hosted secrets platform fronted by an in-cluster operator, and an OpenTelemetry + ELK observability pipeline.

We need an engineer who is comfortable operating Kubernetes day-to-day — Helm, Argo CD, ingress, NetworkPolicies — and is deeply fluent on the Linux command line for the underlying nodes.

This is a collaborative role. You’ll work closely with our platform architect, who is setting direction and standards, and align with the patterns already established by our DevOps engineer on a sister product. You won’t be reinventing — you’ll be executing carefully, raising risks early, and bringing strong Kubernetes and Linux fundamentals to bear

Key Responsibilities:

• Operate our Kubernetes clusters: node lifecycle, upgrades, ingress (cert-manager, external-dns), in-cluster secrets operator, default-deny NetworkPolicies, Kubernetes management UI administration.
• Maintain and extend our parameterized Helm charts; manage Argo CD applications and the GitOps platform repo; execute deploys as values-file commits.
• Run database schema migrations through Argo CD lifecycle hooks.
• Maintain and improve our CI/CD pipelines (build, test, scan, push to our container image registry).
• Administer Linux server nodes end-to-end on the command line: systemd, networking, firewalling, package management, log management, kernel tuning, troubleshooting production incidents.
• Keep the AWS footprint healthy: EC2 (Kubernetes nodes), VPC, security groups, managed PostgreSQL, object storage, IAM, OIDC roles for CI deploys, DNS.
• Operate and extend our self-hosted secrets platform; manage machine identities and environment-scoped secret delivery into the cluster via the operator.
• Operate and extend our OpenTelemetry collector and ELK observability pipeline; ensure new services have proper instrumentation, log shipping, and dashboards.
• Contribute to infrastructure-as-code coverage where it’s missing today, under direction from the architect.
• Improve deploy reliability: progressive rollouts, rollback paths, pre/post-deploy checks, migration safety, deploy observability.
• Keep the developer experience tight: fast pipelines, useful CI signals, reproducible local dev, painless secret rotation.
• Serve as an escalation point for infrastructure issues; participate in incident response and contribute to actionable postmortems

Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or related technical discipline, or equivalent professional experience.
   5+ years of professional DevOps, SRE, platform, or infrastructure engineering experience operating production systems, with at least 2 years of production Kubernetes ops.
• Hands-on production experience operating Kubernetes (any distribution) and writing or maintaining Helm charts.
• Deep Linux fundamentals: shell scripting (Bash), systemd, networking (iptables/nftables, routing, DNS), filesystem and storage layout, process and memory debugging, log management, package management on Debian/Ubuntu and/or RHEL family.
• Strong AWS experience: EC2, VPC, managed databases, object storage, IAM, security groups, OIDC. You can wire all of this up and understand the failure modes.
• Hands-on CI/CD experience designing and maintaining pipelines in Bitbucket Pipelines, GitLab CI, GitHub Actions, or comparable platforms.
• Container experience: Docker, image registries, and Kubernetes workload patterns (Deployments, StatefulSets, Jobs, CronJobs).
• PostgreSQL operational experience: backup/restore, replication, migration tooling, basic tuning.
• Strong systems-thinking mindset; able to reason about failure modes, blast radius, and reversibility before taking destructive action.
• Strong written and verbal communication skills — comfortable working closely with an architect and other engineers, raising questions early rather than guessing.

What We Offer:

• Competitive salary and benefits package. 
• A fast-paced, high-impact work environment.
• Opportunity to work closely with executive leadership.

• The chance to work with cutting-edge technologies and make a significant impact.
• A culture of innovation, ownership, and growth.
