Job Description
Postscript is the AI messaging platform trusted by 20,000+ Shopify brands — including Brooklinen, Ruggable, True Classic, and Dr. Squatch. With a mission to make SMS your number one revenue driving ch
Key Highlights
- System & Platform Design: Own infra topology, scaling and blast-radius boundaries, the build/deploy graph, database ownership boundaries, and cost ceilings — the decisions agents execute but can't make.
- Guardrail Engineering: Build the validation gates, idempotency checks, drift detectors, and runbooks that keep both humans and agents from doing damage. Your deliverable is the safety system, not the deploy.
- Escalation Tier: Diagnose the novel failures — consumer lag, DLQs, materialized-view chains, consent ordering. Write the runbook the first time; agents handle it after.
- Reliability, Capacity & Cost: Own the 500K events/sec target: load testing, Karpenter/HPA tuning, Database sizing, SLOs and alerting.
- Security & Secrets Boundary: Own IAM/IRSA, secret rotation, the auth chain, and what the agent/MCP surface is allowed to do.
