You will build features end to end: the API service on the
backend, the Next.js application on the frontend, and the design decisions that
connect them.
This is a hands-on role with real ownership. You will help
decide how things are built, not just implement someone else's plan.
What you will do
• Build
and maintain Python services (FastAPI) that are rapid on reads and correct
on writes.
• Design
the data model and write the SQL behind it.
• Build
product screens in Next.js and React that hold up with real data: dense
tables, dashboards, forms with complex state.
• Decide
what renders on the server and what renders on the client.
• Add
logging, metrics, and tracing so problems can be diagnosed in production.
• Write
a short design doc before building anything that crosses a service
boundary.
• Review
other people's code carefully.
What we are looking for
Python backend
• 5+
years writing production Python, including a modern async framework such
as FastAPI.
• Comfortable
with async/await, background tasks, and structured error handling.
• You
write tests as part of building, not after.
SQL
• Solid
relational modelling and comfort writing non-trivial queries by hand.
• You
can read a query plan and explain why something is slow.
• You
have run schema migrations on a live system.
Frontend
• 3+
years of production React, with a real understanding of why a component
re-renders.
• Next.js
App Router in production: server components, route handlers, caching.
• TypeScript
used to model the domain, not just to satisfy the compiler.
• A
clear view of what belongs in server state, client state, and the URL.
Architecture and system design
• You
can turn an ambiguous requirement into a design with stated assumptions
and trade-offs.
• Comfortable
with the fundamentals: idempotency, retries, timeouts, caching and
invalidation, consistency.
• You
have made a wrong call, caught it, and fixed it. We will ask about this.
