Our first major platform is Flywheel, a US-based transportation technology company rebuilding regulated taxi and fleet infrastructure across major cities.

Role Overview

We are looking for a Senior Backend Engineer (Go) who can design, build, and operate real-time, high-reliability systems in a fast-moving, AI-native environment.

This is not a maintenance role. This is a builder’s role — for engineers who want to work at the intersection of backend, product, systems, and AI.

What You Will Do:

Backend Ownership (Primary)

You will design and own Go-based microservices powering Flywheel’s core marketplace and operational systems:

• Supply–demand matching
• Dispatch & routing workflows
• Driver onboarding, verification & compliance pipelines
• Pricing, settlement, and reconciliation
• Real-time telemetry ingestion (driver location, status, events)
• Payments & financial flows
• Multi-tenant fleet management

You will architect systems that are:

• Low-latency
• High-throughput
• Fault-tolerant
• Zero-downtime deployable

Full-Stack Contribution (Secondary)

You will also work on internal & customer-facing tools such as:

• Operations dashboards
• Fleet control centers
• Support & compliance tooling

Using:

• React.js / Next.js / Vue.js

Your goal is to ship fast, functional UIs that power real-world operations.

AI-Native Engineering

You will use modern AI tooling to dramatically increase engineering velocity:

• Cursor
• Windsurf
• GitHub Copilot
• Antigravity
• GitHub Code Search

You will help create a culture where:

• Repetitive work is automated
• Engineers operate at 10x–100x velocity

End-to-End Ownership

You will own systems across their full lifecycle:

• Architecture
• Implementation
• Testing
• Deployment
• Monitoring
• Iteration

You will debug complex distributed systems using:

• Logs
• Metrics
• Traces
• Event streams

Must-Have Requirements

1. Go / Backend Expertise

• Strong proficiency in Go (Golang)
• Deep understanding of:
• Goroutines, channels
• Concurrency patterns
• Memory model & sync primitives

2. Marketplace / Logistics Experience

Experience building real-time, operational platforms at companies such as:

Uber, Lyft, Ola, Swiggy, Zepto, DoorDash, Dunzo, Meesho, or similar high-ops platforms.

3. Distributed Systems

Strong experience with:

• Event-driven systems
• Real-time state machines (driver lifecycle, order lifecycle, dispatch lifecycle)
• REST + gRPC services
• Redis & caching strategies
• Retries, timeouts, backoff, fault tolerance

4. Databases

• Strong SQL & data-modeling fundamentals
• PostgreSQL preferred

Additional Technical Expectations

Infrastructure & DevOps

• Docker
• Kubernetes or ECS
• CI/CD (GitHub Actions, GitLab CI, CircleCI)
• Terraform (Pulumi is a bonus)

Observability

• Prometheus, Grafana, OpenTelemetry
• Metrics, tracing, structured logs
• Incident debugging & SLO ownership

Messaging & Streaming

• Kafka / PubSub / NATS
• Idempotent consumers
• Event-driven architectures

Geospatial (Nice to Have)

• Maps, ETA models, geofencing
• H3 / Geohash
• Distance & routing calculations

Security & Compliance

• API authentication
• Least-privilege access
• Auditing & regulatory data retention

You’ll Succeed Here If You Are

• A strong Go engineer who writes clean, production-grade systems
• AI-native — you use AI as a real engineering multiplier
• Comfortable with ambiguity and ownership
• Obsessed with reliability, correctness, and system behavior
• Able to work across backend, frontend, infra, and ops
• Excited by real-world, high-impact engineering

Years of experience do not matter.

Output, clarity, and capability do.

Nice-to-Have Experience

• Transportation, dispatch, logistics, fintech, or regulated platforms
• Driver scoring, compliance pipelines, payments & settlements
• Early-stage startup environments
