Job description

We are working on a Customer Data Platform— a solution that enables companies to efficiently manage end-user data in our new product. Our platform integrates data from various sources (tracking codes, chats, tickets, and custom data) into a unified customer profile. Within this platform, the Customer List sub-team focuses on real-time visitor intelligence. We surface valuable, live information about visitors browsing our customers' websites. Our backend infrastructure handles high-throughput data streams using Kafka and WebSocket pushes, processing over 1 million visitors at peak times.

Our frontend consumes thousands of real-time events, transforming them into clear, responsive, and insightful user experiences. Our mission is to tame the stream of live data and make it actionable, delivering the visibility that helps our customers make smart, timely decisions.

You will be responsible for:

• Developing and enhancing features on the Traffic Page, Customer Details Sidebar, and other future components owned by the Customer Data Platform team.

• Monitoring and improving Text App architecture, including optimizing app performance and reducing security vulnerabilities.

• Designing technical solutions from the ground up — architecting, implementing, and monitoring them.

• Actively engaging in product discovery: breaking down problems, suggesting practical solutions, and delivering them in small, testable increments.

• Participating in engineering discussions, proposing improvements to processes and best practices.

You may be a good fit for this role if you:

• Are a frontend expert with deep knowledge of HTML, CSS, JavaScript, TypeScript, and React.js.

• Have experience working with large-scale systems, including complex state management, WebSockets, and real-time updates.

• Know how to write robust unit tests (Jest) and integration tests (Playwright)

• Are confident in using and debugging REST APIs.

• Have some hands-on experience with Node.js or Go, and you're comfortable enough to deploy your own changes to REST APIs.

• Thrive in a fast-paced, continuous deployment environment using tools like GitHub Actions and feature flags.

• Embrace modern AI tooling or agent workflows as a daily productivity enhancer.

• Take initiative — you don’t wait for tasks, you find problems and solve them.

How we work:

We’re a hybrid team – remote when it makes sense, onsite when it matters most.

Once per quarter, your whole team spends 5 working days together at our Wrocław office – a time for focused execution, unblocking work, and driving key outcomes.

Our office is open year-round – drop by anytime.

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.

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.
