Backend Team Leader
Herzliya, Israel
Full Time
Mid Level
The role
We’re looking for a hands-on Backend Team Leader to lead a team building cloud-native TypeScript microservices on AWS. You’ll work with big data, data pipelines and complex business logic across multiple domains, and own the backend from solution design to production. The team also owns platform/DevOps.
What you’ll do
You’re a player-coach who still codes and reviews deeply, owns production end to end, and measures success by what the team ships. You make clear, pragmatic decisions, give direct and respectful feedback, and stay calm under pressure.
Who We are
Questar is a physical AI company building the next generation of vehicle health management. We detect real vehicle problems before they surface, explain what is happening, and recommend exactly what to do, reducing maintenance costs and downtime for commercial fleets.
We ingest billions of data points every day from our customers’ vehicles and turn them into a Total Fleet Health solution. Questar is a pioneer in total vehicle health management, serving Tier 1 suppliers, OEMs, leasing companies, service providers, and enterprise fleets.
Questar Auto Technologies is an equal opportunity employer. We welcome applicants from all backgrounds and do not discriminate based on race, color, religion, gender, gender identity or expression, sexual orientation, national origin, disability, or age.
