About this role
*"Houston, we have a product problem."*
In 1970, a room full of NASA engineers got a box of spare parts, a hard deadline and one brief: make a square filter fit a round hole, or the crew doesn't come home. Nobody gave them a spec or a ticket. They defined the problem, designed the fix from a blank page and owned the outcome.
That's the engineer this search is for.
THE COMMAND MODULE (TECH DETAILS)
- Core stack:
Node.js and TypeScript across the backend services you'll own and design
- Messaging:
Kafka, RabbitMQ and event-driven architecture, carrying high-volume business transactions between companies, where ordering, idempotency, retries and replay can't go wrong
- Scale:
hundreds of millions of transactions processed for hundreds of customers across thousands of live trading connections, so throughput and reliability are designed in from day one
- AI in the product:
AI built into customer workflows, writing and maintaining the data rules that used to take people weeks of manual setup, and catching errors before they hit a customer's operations
- AI in the workflow:
coding agents are standard on every engineer's desk. You direct them, review their output line by line and own what ships
- Architecture ownership:
you'll write the technical designs for large initiatives and plan for performance, scale and reliability up front
- Product surface:
a self-service platform and API, so customers integrate and go live themselves
