You’ll work closely with a US-based team (Architect + Founder on the client side) and be part of a small, collaborative delivery team where communication and ownership matter as much as engineering quality.

Your impact

• Take end-to-end ownership of product features: from clarification and technical design to production delivery
• Help shape architecture and engineering practices in a platform where performance, reliability, and security are critical

• Implement clean, responsive React UI components and ensure smooth FE/BE collaboration

• Contribute to system design and improvements in performance, scalability, reliability, and security
• Lead complex tasks, support teammates technically, and help evolve coding standards and best practices

What we’re looking for

• 8+ years of commercial experience building web products with Node.js + React
• Strong JavaScript/TypeScript and modern web development practices
• Solid experience with REST APIs, backend services, and database integrations (PostgreSQL, MongoDB)
• Hands-on skills in performance optimization, debugging, security best practices, and scalable architecture
• Confident with Git and collaborative workflows (PRs, code reviews, branching strategies)
• Strong ownership mindset: you can move from “unclear requirements” to a shipped solution

Must-have soft skills (very important)

• Strong spoken English and comfort working daily with US stakeholders
• Ability to build relationships, communicate clearly, and proactively align expectations
• You’re not waiting for tasks — you ask questions, suggest solutions, and keep things moving

Team & collaboration

• Delivery team: 4 Developers + Project Manager
• Client side: Architect + Founder
• You’ll have direct communication and real influence on decisions and delivery

Working hours

You need to be available to work until 12:00–1:00 a.m. Kyiv time (alignment with US team)
