JavaScript Deobfuscation / Reverse Engineering

Charted Sea | JavaScript Deobfuscation / Reverse Engineering | REMOTE | Full-time | https://chartedsea.com/about
We build a SaaS to extract data from complex platforms like Shopee. They use heavy obfuscation & anti-bot systems, and our job is to break them.
We are working on a deobfuscator that turns obfuscated JavaScript into readable code. It behaves like a decompiler:
- restore strings (e.g. `f(42)` → "my-string")
- simplify control flow (`a && b || !a && c` → `if (a) { b } else { c }`)
- unpack sequence expressions (`var a = (c=1, b=1+c, 3+b+c)`)
- decompile a custom bytecode VM (70K instructions)
This is not typical web/backend work. The target platforms evolve constantly.
We're looking for someone who:
- enjoys understanding complex systems by experimentation
- is comfortable with partially understood code
- has built non-trivial tools (parser, interpreter, RE tool, etc.)

You will:
- own the deobfuscator
- work directly with the founder
- have time to go deep (long-term problem)
Stack: TypeScript, Babel
Compensation:
$40k–$80k USD + monthly bonus (10% of net revenue shared with team)
