The Opportunity

We’re looking for a Tech Lead to join the engineering team of one of our partners, a transportation technology company that’s reinventing how people move within their communities. Their on-demand, all-electric microtransit platform connects riders, drivers, and local businesses through real-time operations and smart routing.

In this role, you’ll take ownership of the architecture and reliability of a platform that powers thousands of daily trips across 25+ microservices. You’ll work hands-on to diagnose and fix scaling bottlenecks, stabilize services, and improve system design, while also mentoring teammates and raising engineering standards. This role is a hybrid between senior IC and team lead, combining deep technical execution with architectural vision and leadership.

• Design and optimize real-time, event-driven systems that handle complex distributed workflows.
• Ensure reliability, scalability, and performance across APIs, databases, and infrastructure.
• Promote strong engineering practices in code quality, testing, security, and deployments.
• Support and mentor a team of engineers through reviews, design discussions, and knowledge sharing.
• Foster collaboration and help shape a team culture focused on scalability, reliability, and continuous improvement.
• Partner with leadership to balance feature delivery with platform stability and long-term growth.
• Your qualifications and experience
