Senior Node.js Engineer

We’re looking for a Senior Node.js Engineer with a product mindset - someone who doesn’t just write code, but shapes the product and takes complex features end-to-end: from idea to production. The focus is on technical decisions, production systems, code review, and working closely with client teams and stakeholders. We value autonomy, the ability to get up to speed quickly with unfamiliar code and technologies, constructive discussion of requirements, and helping other engineers grow. It’s a startup environment: fast decisions, shifting priorities, minimal micromanagement, and visible impact on the outcome.
