Senior Full Stack Engineer (Node.js/React)

Hello! 
We are looking for a Senior Full Stack Engineer (Node.js/React) to join a team working with an international client in the renewable energy / green-tech sector.

Location: Ideally Lviv (hybrid) or Remote

About the project:

The client is one of the leading commercial rooftop solar developers in the US, building and operating distributed solar and storage infrastructure on commercial real estate — turning rooftops into clean energy assets. They partner with major real estate owners nationwide and have already deployed hundreds of megawatts of renewable energy projects, backed by over a billion dollars in project financing. This is one of the fastest-growing companies in the green energy space, which makes this a genuinely high-impact, forward-looking project — you'll be contributing to the infrastructure behind the clean energy transition, not just another internal business tool. The team also actively uses AI coding tools (Claude, Cursor) as part of the daily engineering workflow — AI-assisted development here isn't a buzzword, it's a real, everyday practice.

We are considering Senior engineers with 4+ years of solid, proven experience.
 

This is a great opportunity for:

• Engineers who want their work to have real-world impact in the renewable energy / green-tech space
• Developers who want to work daily with AI coding tools (Claude, Cursor) as a core part of the engineering process, not an experiment
• Full Stack Engineers who think beyond the ticket — who want to understand the "why" behind a task, engage directly with business users, and propose solutions, not just implement what's handed to them
• Engineers comfortable communicating directly with non-technical stakeholders and business users
  
  Required Skills
• 4+ years of solid, proven commercial experience with Node.js and React
• Practical experience with AI coding tools such as Claude, Cursor, or similar
• Strong communication skills, with experience working directly with business users

A "product engineer" mindset — someone who understands the purpose behind the work, picks up context quickly, and proactively suggests approaches rather than waiting to be assigned tasks

Will Be an Advantage

• Experience with Microsoft Azure
• Experience integrating with the Microsoft ecosystem (Microsoft Graph, Power Platform, Dynamics 365)
