Note: The job is a remote job and is open to candidates in USA. Replicant builds AI-powered customer service platforms, including AI agents and conversation intelligence for contact centers. The Senior Site Reliability Engineer will shape platform engineering domains, improve production infrastructure reliability for large-scale conversational AI traffic, enhance CI/CD and developer tooling, and participate in on-call and incident management.
Responsibilities
- Contribute to patterns, design, and implementation of our domains; help shape the future of platform engineering at Replicant
- Build and improve systems that help reduce toil and enable Replicant's production infrastructure to remain available and operable under large-scale, real-time conversational AI traffic
- Extend and iterate our agent harness: Unsupervised AI agents are currently used by about 10% of the dev team - help us grow that number. The agent harness includes CI, sandboxes, guardrails, and validation (e.g. agent-first eval loops)
- Own and improve our CI/CD pipelines and surrounding developer tooling: build and test performance, deployment ergonomics, and paved paths for new services
- Participate in on-call rotation and incident management to ensure platform uptime and quality. (SRE owns the base infrastructure, not the applications; non-business-hours pages are rare)
Skills
- 6+ years' experience in software development enablement roles
- Solid experience owning CI/CD platforms end to end - including domains like caching, architecture, and developer self-service
- Effective use of AI tools such as Claude and Cursor for coding, troubleshooting, and reasoning
- You pair these skills with a defensible opinion on where to avoid using AI tools
- Familiarity with Node/TypeScript including making code changes (e.g. exposing new metrics), Python and Terraform for automation, and developing in a Kubernetes/Helm ecosystem
- Practical experience with observability: logs/metrics/tracing, monitoring/alerting, incident management process, and tooling
- Experience working in fully remote teams - tell us how you've made one work better
- Harness engineering experience - building platforms for autonomous agents
- Production-at-scale experience with GCP
- Telephony and SIP architectures, FreeSWITCH in particular
