We're looking for a Senior with 8+ years of experience with a strong knowledge of both Ruby on Rails and Typescript.

Senior Ruby developer ASAP
(Please, send candidates only with the relevant skills specified in the white label CVs!)

FTE: Full time (40 h per week)
Timeline: 3-6 months (tbd)
Start: ASAP
English: B2
Recruitment process: a tech check with us, then an interview with the client

Requirements:
A Full-Stack Craftsman: You are an expert in Ruby on Rails and TypeScript, capable of building everything from complex dashboards and billing UIs to sleek documentation platforms.

The "DevEx" Champion: You have a natural empathy for other developers. You’ll develop deep knowledge of our platform (Pub/Sub, Chat, LiveSync) and use the product yourself to gain a first-hand understanding of the developer experience.

Comfortable with Ambiguity: You thrive in high-level vagueness. You can take a feature from a loose concept to a shipped product with minimal hand-holding, identifying problems and proposing solutions independently rather than waiting for a roadmap.

Accountable & Reliable: You take pride in high-quality, well-tested code. You meet your delivery commitments, provide realistic estimates based on technical complexity, and communicate proactively if a timeline is ever at risk.

An Owner: You monitor what you build in production and take personal ownership of quality issues. You see a feature through its entire lifecycle, from the first line of code to the final metric.
