About the role
Bytebeam's API backend serves more than a million connected vehicles and hardware units. We are now building a separate, next-generation platform to power fleet management, device commands, configuration, and data queries at greater scale.
The high-level architecture is in place. You will turn it into a reliable production system, shaping the detailed design and making the engineering decisions that determine its p99 latency, query performance, and reliability.
What you'll do
- Build Bytebeam's greenfield, next-generation API backend in Rust.
- Design and implement APIs and data-serving paths backed by PostgreSQL, ClickHouse, and DuckDB.
- Measure and improve p99 latency, query performance, throughput, and reliability under production workloads.
- Own services in production, including deployments, observability, capacity planning, on-call, and incident response.
- Lead projects end to end and mentor junior engineers in teams of no more than three people.
What we're looking for
- 5+ years building and operating production backend systems.
- Strong production experience in Rust; 3-4 years is preferred. Experience with libraries such as axum, actix, sqlx, or SeaORM is useful.
- Strong systems fundamentals across concurrency, networking, storage, and failure handling.
- Deep understanding of database and query optimization. Production experience with PostgreSQL and ClickHouse is a big plus.
- A strong bias toward measuring systems before optimizing them, especially p99 latency, query performance, and throughput.
- Experience owning production reliability and mentoring engineers.
Why Bytebeam
- Build a greenfield platform informed by the real workloads of more than a million connected units.
- Own meaningful systems from detailed design through production operation.
- Work in small, high-ownership teams with a direct line between your decisions and customer impact.
