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

  • Take deep ownership of systems and product areas on your team — becoming the go-to technical expert for what you own
  • Independently investigate, design, and execute solutions across distributed systems with a high degree of ambiguity
  • Architect, build, and maintain highly available, scalable REST APIs and backend services for internal and external use
  • Drive system decoupling, modularization, and technical debt reduction — improving long-term maintainability without blocking near-term delivery
  • Build agentically as your default: run multiple autonomous agents and worktrees in parallel (5+ is the benchmark), own the output, and keep a steady queue of aligned work moving

Qualifications

Required Qualifications

  • 6+ years of experience building large-scale backend systems and APIs
  • You are an active, daily user of AI coding tools and are using them to maximize your output — Claude Code, Cursor, Copilot, or equivalent — and can speak concretely to how they've changed your output and your workflow
  • Tech stack: Python, Go, React, and TypeScript; experience with Kubernetes, AWS, Datadog, and relational/NoSQL databases.
  • You follow the AI tooling landscape closely: new model releases, emerging agentic workflows, and evolving best practices aren't things you catch up on eventually — they're things you're tracking in real time
  • You think critically about AI output — you know where it accelerates you, where it introduces risk, and how to verify what it produces
  • You are able to context switch extremely quickly across concurrent workstreams
  • Experience working on both 0-to-1 initiatives and complex existing systems — and knowing how to balance building new things with improving what's there
  • Strong command of relational and NoSQL databases, SQL, and thoughtful database modeling
  • Familiarity building and observing applications on AWS, and ideally with Datadog or comparable observability tooling
  • Clear, direct communication — cross-functional partners and async teams can count on you to surface information proactively
  • Strong instincts for technical tradeoffs informed by both engineering best practices and business priorities
