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.
