The Brief

What you'll do, and what you'll demonstrate.

Build a working FUSE driver over an S3-compatible API and honestly assess whether it's production-viable for backup workloads.

This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.

When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."

Earning criteria — what you'll demonstrate

Understand the VFS layer and how FUSE proxies it to user space
Implement correct POSIX semantics for read/write/metadata operations
Benchmark file-system workloads with reproducible setup
Make a defensible go/no-go technical recommendation

Canonical roles

Backend Engineer
Behind every app a user touches, there's a quieter system doing the actual work — routing requests, holding state, refusing bad input politely. Backend engineers build and care for that hidden layer. The role is part craft, part diplomacy: you're designing APIs that other engineers will lean on for years, and a careless schema choice can echo through a company for a long time. Good work here looks like code that's boring in the best way — predictable under load, easy for the next person to read, observable when something breaks. Students grow into this role by getting comfortable with Python or another server language, then learning how databases really behave when traffic spikes.
