Software Engineer, Agent Builder

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

Software Engineer, Agent Builder at Sierra, focused on building a platform for AI-powered customer experiences. The role involves developing simulation and benchmarking tools for AI agents, creating no-code tools for guiding and testing agents, adapting software development methodologies for AI agents, and accelerating agent creation using generative tools and self-improving systems.

What you'd actually do

  1. Simulation & Benchmarking: How can we craft a simulation platform to test AI agents against every real-world scenario imaginable?
  2. Content Management: How do we create intuitive, no-code tools that allow anyone to guide and test AI agents?
  3. Agent Development Lifecycle: How do we adapt traditional software development methodologies to accommodate AI agents’ non-deterministic behavior, natural language interactions, and reliance on large language models?
  4. Generative Agent Development: How do we accelerate agent creation using generative tools like Cursor and Claude Code? Can we build self-improving systems based on real-world interactions, customer-driven feedback, and self-play?
