Opis stanowiska
Nasze wymagania:
A fullstack craftsman. You're strong in Ruby on Rails and React and comfortable moving across the stack - from complex dashboards to sleek documentation platforms.
A DevEx champion. You have natural empathy for other developers and genuinely care about the developer experience of the tools you build.
Comfortable with ambiguity. You thrive when the brief is vague. You identify problems, propose solutions, and ship with minimal hand-holding.
An owner. You see features through their entire lifecycle — from the first line of code to the final metric in production. Quality issues that surface after release are still yours.
A proactive communicator. You give realistic estimates, meet your commitments, and speak up early if a timeline is at risk.
Fluent with AI coding assistants. The team uses them actively for planning, prototyping, and iteration — you should too, while owning the correctness and quality of everything that ships.
Design and UX intuition. You notice when a flow feels wrong and you're not afraid to say so.
Mile widziane:
Experience building developer-first products or working on B2D platforms
Experience with products grown through product-led growth (PLG)
Background in real-time, messaging, or infrastructure-adjacent products
O projekcie:
Some products you use every day without ever seeing them. This is one of those.
Our client is a well-established B2D (business-to-developer) SaaS platform -real-time infrastructure that moves billions of messages a day for developers around the world. Live chat, dashboards, collaborative apps, state synchronization: if it updates in front of your eyes, there's a good chance technology like this is running underneath.
Tech stack
React + TypeScript on the frontend, Ruby on Rails on the backend, some Node/TypeScript services, PostgreSQL underneath.
Zakres obowiązków:
This is a product-minded engineering role, not ticket execution. The team is deliberately moving away from reactive delivery toward engineers who understand customers and drive outcomes. You'll take features from a loose concept to shipped and monitored in production — dashboards, billing UIs, documentation platforms, developer-facing tools — proposing what should be built, not waiting for a roadmap to tell you.
And here's the fun part: the customers are developers. You'll use the product yourself and fix the frustrations you'd want fixed.
