About the role

Key Responsibilities

  • Design, build, and operate mission-critical APIs that provide our customers the building blocks for frontier intelligence.
  • Ensure low latency and high throughput through aggressive performance optimization (including on upstream systems).
  • Continually reimagine the customer needs of tomorrow (and the architectures to serve those needs), while faithfully serving the customer workloads of today.
  • Harden system security and reliability across heterogeneous compute environments.
  • Collaborate across teams to incorporate novel frontier capabilities into the API Platform and improve existing capabilities for API customer needs.
  • Uphold engineering excellence through design reviews, code quality, and internal documentation.

Qualifications

  • 5+ years of backend engineering experience with Python, Go, or Rust.
  • Strong understanding of high-traffic API design: schema evolution & versioning, idempotency, authentication patterns, rate limiting, and performance tuning.
  • Hands-on cloud experience (AWS preferred), along with fluency with Kubernetes, CI/CD, and modern DevOps practices.
  • Experience with modern AI APIs (including latency tuning, streaming, model orchestration, emerging technical standards) is a strong plus.
  • Strong customer empathy and product sense, ensuring the APIs you build are ergonomic, well-documented, and easy to adopt for developers and agents alike.
