About The Role
We’re looking for a product-minded Fullstack Engineer to join our Growth R&D team. This is a high-impact engineering role focused on building web-based tools, experiments, and internal automations that power scalable user acquisition and engagement strategies.
You’ll work side-by-side with our Head of Growth to create, test, and iterate on product-led growth initiatives — from standalone tools (like Typing Speed Test or AI Email Generator) to data-driven content engines, automation frameworks, and internal growth infrastructure.
The ideal candidate is comfortable working across the stack (React + Node.js/Fastify), thrives in fast-paced, experimental environments, and is excited about building things that go live quickly and are seen by millions of users.
This is not a feature factory — we build things that grow.
