The Role
This is a hands-on senior engineering role with clear technical leadership responsibility.
You will:
- Be deeply involved in designing and building backend systems
- Take ownership of code quality, architecture, and technical direction
- Act as a technical reference point within the team
- Support and mentor engineers through collaboration, reviews, and guidance
- Work closely with the Engineering Manager on technical execution and quality
What You’ll Do
- Design, implement, and maintain scalable backend services
- Lead architectural discussions for distributed systems
- Own and continuously improve code quality and system reliability
- Drive design and code reviews with a high engineering bar
- Mentor engineers and help unblock complex technical challenges
- Collaborate with Product to translate requirements into robust technical solutions
- Identify technical risks and ensure long-term maintainability
- Contribute to a culture of ownership, learning, and accountability
What We’re Looking For
- 8+ years of backend engineering experience in production environments
- Proven experience working on high-traffic, distributed systems
- Strong fundamentals in distributed systems (consistency, concurrency, failure modes)
- Hands-on experience with Node.js in production
(Engineers with prior experience in Go, .NET Core, Java, etc. are very welcome — language maturity matters more than syntax)
Solid knowledge of PostgreSQL and relational data modeling
Experience with message-based systems (e.g. Kafka, RabbitMQ, or similar)
Experience with Redis and in-memory data stores
Strong understanding of microservices architectures and their trade-offs
Ability to lead technical decisions and guide the team without formal people-management authority

A strong sense of ownership and responsibility for team outcomes
What Success Looks Like
- Backend systems scale reliably under increasing load
- Code quality and architectural clarity improve over time
- Engineers feel supported, unblocked, and technically confident
- Technical decisions are well-reasoned, shared, and easier to evolve
- Engineering Manager can delegate technical ownership with confidence
Why Join
- Work on real-time mobility systems, not CRUD-heavy backends
- Take on technical leadership with real ownership
- Focus on engineering quality and system design
- Collaborate with strong Product and Platform teams
- Make visible impact on both systems and engineers
