You’ve built and shipped products that customers rely on, and you care about the user experience as much as the code

You’re strong across the stack. You know at least one area deeply (complex front-end apps, API design, or backend performance) and are comfortable working in the others.

You enjoy hard problems at the line between UX and systems: a canvas that lags with 200 nodes, a workflow with too many clicks, a query that times out, a queue that won’t drain

You ship early and often, use data and customer feedback to iterate, and work closely with product and design

You thrive on a small, autonomous team where you own outcomes and collaborate widely to get them right

You’re curious about how AI changes both what we build (agents that build flows) and how we build it

Technologies we use (not exhaustive)

React, TypeScript, JavaScript

Python, Django, Celery

MySQL, Redis, RabbitMQ, Kafka
