Sierra Sierra · AI Frontier · San Francisco, CA · Engineering

Software Engineer, Platform role focused on building Sierra's AI platform for customer experiences. The role involves creating platform primitives for agent development, orchestration, and deployment, including runtime systems and developer tooling. Experience with production systems and distributed systems is required, with a passion for AI products being a plus.

What you'd actually do

  1. Build Sierra’s platform. At Sierra, we believe agent development is an evolution of software development that requires new tools and systems. You will work on the platform primitives that power how agents are built, orchestrated, and deployed.
  2. Invent the foundations of agent development. You’ll design systems that enable engineers and customers to build reliable, steerable agents, including runtime systems, developer tooling, and internal infrastructure.
  3. Enable engineers to move faster. You’ll build tools and workflows that accelerate how engineers build and deploy agents across Sierra.
