Senior Flutter NestJS React Logistics Platform Engineer
Opportunity Summary
You will join an experienced engineering effort to implement a freight matching and logistics platform built around a unified modular backend. The system drives multiple client surfaces with a strict event-driven trip lifecycle and an automated double-entry escrow ledger. Responsibilities include building functionality across shared authentication with phone plus OTP, then developing and maintaining the five surfaces, with Flutter for mobile and React for web, backed by NestJS. The architecture is locked, delivered across a sequence of short sprints, so the best fit is someone who can execute carefully within constraints. Expect to collaborate closely on correctness, integrations, and consistent behavior across all surfaces.
Ideal Candidate
A senior engineer or technical lead with deep experience in event-driven backends and cross-platform frontend development. They can work confidently inside a defined architecture, delivering reliable integrations across web and mobile.
Project Insights
- Experience with event-driven state machines reduces regressions in complex lifecycles
- Shared backend contracts help keep all five surfaces aligned
- Strong automated testing for lifecycle transitions improves reliability
How to Prepare
- Review event-driven lifecycle patterns and share how you validate state transitions
- Describe your approach to ledger correctness and related integration testing
- Provide examples of building OTP flows and shared auth components across clients
Typical Challenges
- Implementing consistent event-driven trip lifecycle behavior across multiple surfaces
- Maintaining correctness for escrow ledger flows and lifecycle transitions
- Integrating phone and OTP authentication across shared modules and clients
