Teams at White Circle

Design, build, and own backend services in Rust for real-time policy checks at scale. Ship end-to-end features from API design to deployment, optimize performance and reliability, collaborate with product and ML teams, and improve observability and throughput for high-volume APIs and data pipelines.

Build and maintain end-to-end automated test frameworks for web and API platforms, integrate tests into CI/CD, own test coverage, write bug reports, and improve test reliability and speed.

Train and fine-tune vision-language models and extend them to video with temporal and long-context modeling. Build multimodal alignment pipelines (GRPO, DPO, reward modeling), curate large-scale datasets (including synthetic), develop evaluation benchmarks, optimize and deploy models for production (quantization, batching, latency), and work with MoE architectures and distributed training.
