skills: javascript, typescript, babel, reverse engineering, deobfuscation, parser, interpreter

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)
