About Retell AI
At Retell AI, we're not just automating calls-we're transforming how the world communicates. Our AI voice agents are reshaping sales, support, and customer engagement for leading brands. Backed by Alt Capital, Y Combinator, and top-tier investors, we've raised $4.7M in seed funding and hit $14M ARR with just 12 people.
We're one of the fastest-growing Voice AI startups and we're on a mission to become the standard for voice automation at scale. We're also one of the top ranking startups at https://leanaileaderboard.com/.
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 3+ years of deep 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. Job Details
