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.

Responsibilities

  • Build and scale fast, high-performance web applications and microtools
  • Design and implement backend APIs and data pipelines using Node.js and Fastify
  • Integrate third-party APIs and external data sources to power new products
  • Maintain and evolve existing tools and platforms with a focus on performance and SEO
  • Participate in growth experiments, prototyping, and rapid iteration cycles
  • Ensure code quality, scalability, and maintainability across projects
  • Own the end-to-end delivery — from concept to deployment

    • What We’re Looking For

  • 5+ years of experience building production-grade fullstack applications
  • Solid knowledge of modern JavaScript (ES6+), React, and Node.js
  • Experience with backend development (REST APIs, Fastify, or Express, async workflows)
  • A product-focused mindset: you care about impact, not just code
  • Experience with rapid prototyping and iterative engineering
  • Strong understanding of web performance, SEO fundamentals, and data flow
  • Ability to work autonomously and iterate quickly based on feedback and metrics
  • Bonus: experience working on tools, automations, or SEO-driven platforms

    • Additional Information

    This role is perfect for a builder — a creative engineer who loves turning raw ideas into polished, working products. If you enjoy hacking on fast-moving projects and solving real-world problems through code, let’s talk.
