About The Role

As a Founding DevOps Engineer, youll be the owner of our build, release, and runtime foundations. Youll 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. Youll work cross-functionally with product, security, and customer teamsthen 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.
