About the Project

We’re seeking a seasoned JavaScript/TypeScript Developer with a strong sense of ownership and maturity in evaluating and improving existing codebases. This role goes beyond pure coding—we want a pragmatic problem-solver who can challenge assumptions, push for technical consistency, and elevate engineering standards across services.

You’ll be part of a remote-first team primarily based in Ukraine, working closely with our Israeli counterparts. We operate in a microservices-oriented environment with cross-functional collaboration at its core. You’ll engage regularly with the Full Stack, Research (Data Science & Engineering), and Product Owner teams to help turn ideas into production-ready services.

We value soft skills as much as technical ones. You should be a proactive communicator, capable of aligning with non-engineering peers, asking the right questions, and pushing back when things need clarification.

This is an AI-first organization—we expect our engineers to leverage AI tools regularly to boost productivity, code quality, and development velocity.
