We’re looking for a product-minded Fullstack Developer 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 development

  • 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

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.


How we work

We have implemented a hybrid workplace, in which our team in Wrocław and nearby (up to 50 km), follows a 3/2 model: three days in the office to foster creativity, teamwork, and social interaction, and two days working from home.

If you’re based outside of Wrocław, you'll work in the office for three days each month to maintain valuable face-to-face connections, while continuing to contribute significantly to product development remotely.

Benefits

We don’t want you to worry about all the basic benefits - like a Multisport card, private health care, or a home office equipment budget.

What we really want you to feel and what we believe in is that the real benefits come from the culture we’ve built.

With a hybrid work model (whether it's three days per week or three days per month, depending on your location), unlimited paid days off and sick days policy, an environment focused on outcomes instead of worked hours, and people dedicated to their work, you’ll find a workplace where you can thrive.

And here’s the icing on the cake: you’ll have the opportunity to work with the makers behind all Text products: LiveChat, ChatBot, HelpDesk, KnowledgeBase, OpenWidget.

Are you feeling like this might be a great place to consider working for? We feel it too ;) Join us and apply.
