Senior / Staff Platform Engineer (AWS · Infrastructure · Distributed System)

• PayNotes — Programmable payments with conditional capture, milestone releases, refunds, vouchers, and partner settlement.
• MyOS — SaaS orchestration layer for merchants and agents. Cross-platform trust, without writing a line of Blue Language yourself.

The Role

You will own features end-to-end — from the React component a merchant clicks to the Lambda function that settles their transaction to the AWS infrastructure that keeps it all standing. No handoffs between "front" and "back". No waiting for someone else to unblock you.

This is a high-trust, high-autonomy role. You'll work directly with the founding team, your decisions will ship to production fast, and yes — you'll be on the hook when something breaks.

• Deep AWS expertise across compute, messaging, storage, networking, and observability — not just familiarity, but operational instinct built from running things in production
• Strong IaC discipline — CDK, SAM, or CloudFormation; you version everything, you don’t click in consoles
• Understanding of distributed systems fundamentals: ordering guarantees, idempotency, at-least-once delivery, outbox patterns, partial failure recovery
• Experience operating event-driven architectures under load — you know what failure looks like before it becomes an incident
• Enough application-layer literacy to read TypeScript/Node.js code and understand what a service is doing, not just that it’s running
• Strong opinions about observability — structured logging, distributed tracing, dashboards built for on-call humans at mam

What you get?

• Competitive B2B compensation based on experience
• Equity — own a piece of what you build
• Fully remote work in an async-first environment
• Direct collaboration with the founding team
• High autonomy and fast decision-making
• Small team, outsized impact
• Work on technology that is genuinely novel
• End-to-end ownership across product, systems, and production

Protocols don’t get built by committees. They get built by small teams who understood the problem before anyone else did.

What You'll Do

Requirements

We’re not looking for someone to manage servers. We’re looking for an engineer who looks at a distributed, event-driven system and immediately sees the failure modes, the ordering edge cases, and the places where a misconfigured queue will silently corrupt state. Someone who automates everything, documents why, and gets angry when something requires a manual step.

• 6+ years building and running production infrastructure.
• Deep AWS knowledge and strong operational instincts.
• Infrastructure as Code only — no manual steps, no console dependency.
• Strong distributed systems thinking: ordering, retries, idempotency, recovery.
• Experience with PostgreSQL, Lambda, SQS, Redis, S3, and CI/CD.
• Obsessed with reliability, security, visibility, and automation.
• Comfortable owning critical infrastructure end to end.
