About the role

  • Architect and evolve core backend systems—event ingestion, real-time risk evaluation, semantic search, and investigation-grade querying.
  • Design and optimize streaming data pipelines using Kafka, Redpanda, or similar technologies to support high-throughput, low-latency processing of LLM interactions.
  • Define and refine data models and schemas across structured (Postgres), analytical (ClickHouse), unstructured (S3), and vector (Qdrant) storage layers.
  • Identify architectural weaknesses and performance bottlenecks across ingest, indexing, and query layers; lead improvements to support scalability, correctness, and observability.
  • Implement data ingestion and transformation frameworks that support policy evaluation, semantic analysis, and dynamic response.
  • Optimize query performance, storage efficiency, and retrieval accuracy to support deep investigation and real-time enforcement.
  • Build and maintain backend APIs, monitoring infrastructure, and policy enforcement workflows that underpin the ThirdLaw platform.

Requirements

  • 10+ years of backend or data engineering experience, ideally with a focus on distributed systems or streaming architectures.
  • Strong in Golang and/or Python; experienced with gRPC, REST, and working in Unix/Linux environments.
  • You’ve been the architect behind at least one complex distributed system—ideally involving real-time data, search, or observability—and can explain your design decisions clearly.
  • Familiarity with schema evolution, ORMs, and data mapping strategies in evolving analytics systems.
  • Comfort working with Kubernetes and cloud-native services in AWS/GCP/Azure.
  • Ability to debug deeply, reason about performance tradeoffs, and own systems end to end.
Benefits
  • We pay market cash compensation and generally above-market equity.
  • We have well-designed and generous benefits.
