Liberate - Staff Software Engineer (DevOps / Platform Engineering)
Requirements
• 8+ years of DevOps, SRE, or platform engineering experience operating production systems at scale. • 8+ years • Deep hands-on AWS expertise (EKS, IAM, VPC, ALB/NLB, CloudWatch, KMS). • Strong experience with Kubernetes, container orchestration, and multi-environment management. • Kubernetes • Proficiency with Terraform or other IaC tools and GitOps workflows. • Terraform • High proficiency in Python, Go, or Typescript for tooling, automation, and internal platform services. • Python • Typescript • Experience with Traefik, HAProxy, or similar load-balancing and routing systems. • Traefik • Familiarity with secure network architectures, MTLS, certificate hierarchies, and service-to-service authentication. • Strong background managing CI/CD systems such as GitHub Actions and CodeBuild. • Ability to lead incidents, design SLOs, and drive reliability across mission-critical systems. • Excellent communication and leadership skills in distributed teams. • Experience with PBX or telephony systems in AWS, SIP routing, or real-time communication pipelines. • Experience with voice agents, WebRTC, or low-latency streaming services. • Prior work in regulated or enterprise environments where compliance is a first-class requirement. • Experience scaling infra in fast-growth startups. • Contributions to open source, infrastructure design talks, or technical publications.
Responsibilities
• Infrastructure Architecture and Ownership • Lead architecture and operation of core AWS infrastructure including PBX systems, EKS, networking, IAM, VPC design, and secure environment isolation. • Own and improve Canary routing infrastructure for LRA (LLM REST API) via Traefik and GitOps patterns. • Maintain and optimize CI/CD flows including GitHub-based CodeBuild jobs, artifact pipelines, and environment promotion workflows. • Secure Integrations and Network Edge • Manage and evolve MTLS proxy infrastructure used to integrate with carrier systems like Frontline. • Own HAProxy-based proxy fleet, certificate lifecycle, root CA management, and IP-restricted ingress patterns. • Ensure secure, audited access to production systems, tokens, and root-level accounts. • Operational Excellence • Lead incident response, on-call rotations, and postmortems. Improve reliability metrics (SLA/SLO/SLI) for voice, agent runtime, and workflow systems. • Maintain and improve non-obvious production infra details including external service dependencies, version pinning, and update cadences. • Partner with AWS Support to optimize pricing, scaling configs, and resource utilization. • CI/CD, Tooling, and Developer Experience • Modernize developer workflows: streamlined builds, repeatable environments, safe deployment strategies (blue/green, canary, feature flags). • Build internal tools and abstractions to make engineers productive while enforcing safety, configuration hygiene, and compliance requirements. • Compliance and Security • Lead infrastructure-related components of SOC2, pen-testing, and Vanta-driven controls. • Ensure auditability, traceability, secure storage of credentials, and alignment with enterprise customer expectations. • Cross-Functional Leadership • Work closely with AI Platform, Forward Deployed Engineering, and Product teams to translate business goals into scalable infrastructure decisions. • Mentor engineers across DevOps, platform, and backend areas. Help set engineering standards and raise operational maturity across the org.
Benefits
• Our platform supports real-time, multi-agent reasoning and voice workflows that depend on low latency, reliability, and airtight security. This role is the backbone of that capability. If you're excited to own mission-critical infrastructure in a company where infrastructure is product, we’d love to talk. • Strong preference for Boston or San Francisco based, but open to remote within the U.S. • Boston; $180,000-$240,000 + equity • San Francisco; $190,000 - $250,000 + equity
