at Lime

🏢 About Lime

Lime is a leader in shared electric scooters and bikes, operating in over 200 cities globally to reduce urban carbon emissions. Their mission-driven culture emphasizes sustainability, innovation, and operational efficiency, making it an exciting place for engineers who want to impact real-world transportation.

About This Role

As a Senior Fullstack Engineer on Product Tooling, you'll build and maintain web applications for both external users (like riders) and internal teams (like operations). You'll lead complex projects, mentor peers, and ensure system reliability, directly enabling Lime's growth and operational excellence.

💡 A Day in the Life

Start by checking dashboards and logs for any overnight incidents, then join a standup with your product team. Spend the morning coding a new API endpoint for internal fleet management, followed by a design review with PMs and designers. After lunch, mentor a junior engineer on code reviews, then wrap up by monitoring deployment of a new feature for riders.

🎯 Who Lime Is Looking For

  • You have 5+ years of fullstack experience, with a strong backend focus (e.g., Node.js, Python, or Go) and modern frontend frameworks (React, TypeScript).
  • You've led large-scale projects from planning to launch, coordinating across multiple teams and stakeholders.
  • You are customer-obsessed, always prioritizing user needs and taking ownership of outcomes.
  • You are passionate about sustainable urban mobility and eager to contribute to Lime's mission.
