Job Description

Principal Engineer – Real-Time Data Systems

Calliere Group

• Shape and scale our real-time data streaming systems — the backbone powering billions of in-the-moment decisions across our platform. • Architect and improve services that process millions of events per second with single‑digit millisecond latency, touching almost every part of our data plane. • Tackle challenges few companies face: ultra‑low‑latency ingestion, distributed caching, deduplication at scale, and fault‑tolerant event computation. • Be the type of engineer who gets excited by raw throughput charts translating into better customer outcomes.

Job Requirements

  • Deep expertise in distributed systems, stream processing, or event-driven architectures (Kafka, Flink, Pulsar, etc.)
  • Experience building low-latency or high-throughput systems at scale.
  • A product mindset. You care deeply about the end impact of your code.
  • Comfort owning major initiatives in a fast-moving, high‑autonomy environment.
  • Strong communication skills and a desire to mentor others.
