Senior Back End Engineer

About Seoul Robotics

Seoul Robotics builds autonomous driving systems for factories, ports, logistics yards, and airports. We offer two approaches: a vehicle-centric system, where autonomy runs on the vehicle itself, and an infrastructure-centric system, where the site coordinates and drives vehicles. That lets us automate whole operations, not just one vehicle at a time.

We work with global automakers and industry leaders, including BMW, Mercedes-Benz, Nissan, Hyundai, Mitsubishi, Volvo CE, Mando, LG, and SKT. We are expanding quickly across ports, logistics yards, and airports.

We are an international team with members from more than 10 countries. English is our working language.

Mission of the Role

We are seeking a highly motivated and experienced Senior Backend Engineer to join our team dedicated to autonomous driving technology. The ideal candidate will have a strong background in Go service development, a good understanding of RESTful API design and experience building fault-tolerant, real-time systems. You will play a crucial role in maintaining and expanding the backend responsible for streaming live fleet state to operators and relaying commands to the autonomy stack.

Key Responsibilities

• Design and implement services in Go, following a domain-driven design.
• Build and maintain event pipelines between the operator-facing layer and autonomy stack.
• Define and extend RESTful API contracts that teams can build against with confidence.
• Deliver real-time state to operators over event-driven and streaming connections, with a focus on robustness and redundancy.
• Maintain and extend operator-facing data in PostgreSQL through versioned migrations.
• Maintain and extend service instrumentation so system behavior stays observable as new features land.

Basic Qualifications

• 5+ years building backend services, with production Go experience.
• Experience delivering real-time state to clients over WebSockets, SSE, or gRPC streaming, including reconnection and backpressure handling.
• Experience designing message-driven systems with explicit delivery and ordering guarantees.
• Experience designing versioned REST APIs.
• PostgreSQL, including query optimization and versioned schema migrations.
• Experience building services that degrade gracefully and recover from partial failure.
• Strong English communication and comfort working cross-functionally with autonomy, QA, and operations teams.

Preferred Qualifications

• Experience working on large-scale distributed systems.
• Experience working with real-time or streaming systems (e.g. WebSockets or similar).
• Familiarity with monitoring and logging tools such as Prometheus, Grafana.
• Familiarity with TypeScript and ability to support the frontend team.
