## About the role

We are looking for a Senior Software Engineer to build the backend for our data collection efforts. You will own the architecture that captures, buffers, processes, stores and retrieves our multimodal data. You will design a hybrid on-premise and cloud infrastructure that can support TB-scale data collected daily. You will also collaborate closely with our AI team to inform the design of the data infrastructure that will deliver high-performance, training-ready datasets for our foundation models.

## What they're looking for

- 3+ years of experience shipping production-grade backend systems
- Expert-level proficiency in Python, Rust, C++ or Go
- Proficiency with high-performance messaging and queuing tools (e.g., ZeroMQ, Kafka, RabbitMQ, Redis Pub/Sub) for inter-process communication
- Strong experience architecting and managing infrastructure on major cloud providers (AWS, GCP, or Azure)
- Experience with high-performance data transfer techniques, such as zero-copy networking, shared memory (IPC), or memory-mapped files
- Experience with time-series databases (e.g., TimescaleDB, InfluxDB, ClickHouse) and efficient file formats for data lakes (Parquet, Avro, Arrow). You understand the trade-offs between write-heavy and read-heavy optimization
