Trusted by over 1 million brands in 170+ countries, we’re an official Meta Business Partner, backed by Bessemer Venture Partners. Manychat runs AI features for businesses worldwide, and we’re hiring an SRE to own the reliability, performance, and cost of that AI infrastructure, and to raise the bar for how our whole engineering org builds on LLMs.
We need someone AI-native: you already understand how modern LLM systems behave in production, things like token throughput, provider rate limits, degraded model quality, and inference latency tails, and you treat all of that as a first-class reliability concern, not an afterthought.

Own reliability and performance of our AI infrastructure: AI Gateway, inference services, and integrations with Amazon Bedrock, Azure OpenAI, and other LLM providers.
Build observability for AI systems: latency/throughput/error SLOs per model and provider, token-level metrics, quality and drift signals.
Run capacity planning and incident response for inference services; 5+ years in SRE / platform / infrastructure engineering,



including production ownership at significant scale.
~ Deep cloud‑native background: AWS, Kubernetes, Terraform/IaC, CI/CD.
~ Strong observability practice (Prometheus/Grafana, OpenTelemetry, or equivalent) and experience defining SLOs for non‑deterministic systems.
~ Proven cost‑optimization work: you can show where you cut cloud or inference spend and how you made cost visible.
~ LiteLLM, Kong AI Gateway, custom).
Experience with eval pipelines and quality monitoring for LLM outputs.

Hybrid onboarding to start work remotely and relocation support for you and your family.
Comprehensive health insurance for both you and your family.
