Founding DevOps Engineer

Senior Software Engineer, Infrastructure

Retell AI is using first principles to reimagine the call center with cutting‑edge voice AI. Thousands of companies now utilize Retell’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled to $60M ARR with a team of 40 people, up from $5M at the start of 2025.

Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI.

As a Senior Software Engineer – Infrastructure, you’ll own 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 and turn what you learn in the field into reusable platform capabilities.

• 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, and 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 & post‑mortems; drive resilience, cost, and performance improvements.
• Document release processes and platform conventions; codify best practices into tooling and templates.

• 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 Git Hub Actions / Git Lab 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.
