About the Role
As a Founding DevOps Engineer, you’ll be the owner of our build, release, and runtime foundations. You’ll design and automate deployment pipelines for both cloud SaaS and on-prem environments, orchestrate containers at scale, and ship reliable releases that meet compliance requirements. You’ll work cross-functionally with product, security, and customer teams—then turn what you learn in the field into reusable platform capabilities.
Key Responsibilities
- Own CI/CD end-to-end: design, implement, and operate pipelines with blue/green, canary, and phased rollouts; define graceful draining for HA systems.
- Architect, maintain, and harden Kubernetes-based runtime (Docker, Kubernetes, Helm), including multi-cluster and multi-tenant concerns.
- Manage cloud deployments across AWS/Azure/GCP and coordinate with on-prem infrastructure teams; standardize with IaC (e.g., Terraform).
- Implement robust observability (metrics, logs, traces), SLOs/error budgets, and automated rollback/one-click restore.
- Partner with compliance to integrate SOC 2 / ISO 27001 / HIPAA controls into pipelines (artifact signing, SBOMs, change management, access/keys).
- Deploy at customer sites (cloud or on-prem), collaborating with client teams for integration, runbooks, and handover.
- Lead incident response & postmortems; drive resilience, cost, and performance improvements.
- Document release processes and platform conventions; codify best practices into tooling and templates.
You Might Thrive If You
- Have deep hands-on experience with a major cloud (AWS, Azure, or GCP) and container orchestration (Kubernetes, Helm).
- Build production-grade CI/CD with GitHub Actions / GitLab CI / Jenkins (or similar), including complex rollout strategies.
- Have shipped both SaaS and on-prem solutions, navigating networking, security, and environment drift.
- Can integrate compliance and security into delivery (secret management, image signing, policy-as-code).
- Are comfortable with networking fundamentals, security hardening, and performance tuning.
- Communicate clearly, move fast in ambiguity, and enjoy being the responsible adult in prod.
