Full Job Description
What you'll do
  • Design and deliver production-grade AI agents: You'll build and ship highly performant, reliable, and intuitive AI agents that are central, mission-critical and drive revenue directly to Sierra's growth. These aren't prototypes-they are powerful, scalable systems running in production environments across industries like finance, healthcare, and commerce.
  • Drive the Agent Development Life Cycle (ADLC): You'll have complete ownership and autonomy from initial pilot through deployment and continuous iteration. You'll be responsible for building, tuning, and evolving AI agents in production environments, defining the standard for ADLC best practices along the way.
  • Partner with large enterprises and cutting-edge startups: You'll work directly with leaders at some of the world's largest enterprises to understand their most pressing business challenges, and build AI agents that transform how they operate at scale. You'll also partner with the most cutting-edge startups in Silicon Valley, embedding AI agents across their entire business stack to drive innovation and efficiency.
  • Build the future of the platform: Your direct work with customers will guide the evolution of Sierra's core platform. You'll surface unmet needs, prototype new tools and features, and collaborate with research, product, and platform to shape the future of AI agent development and Sierra's product.
Example projects

These are some examples of projects that engineers on our team have worked on recently:
  • Design and build AI agents for large telecommunications and media companies that consistently outperform human agents in managing subscription churn
  • Develop and refine AI agents capable of navigating complex customer interactions, like troubleshooting a broken device and personalizing product recommendations
  • Create generalizable AI agent frameworks tailored for industry-specific use cases. See some examples in our financial services blog!
  • Facilitate design partnerships for new product initiatives, such as new agent architectures, self-service capabilities, and generative agent development
  • Experiment with the latest voice models and figure out how to integrate them at scale to enterprise-grade customers
What you'll bring
  • Language fluency - professional fluency in both Brazilian Portuguese and English
  • Experience building and scaling end-to-end production systems
  • Strong technical problem-solving skills, especially in fast-changing, ambiguous environments
  • A builder and tinkerer's mindset with high agency - you find creative ways to overcome obstacles and ship
  • Comfort working directly with customers to understand their needs and solve real-world problems
  • Excellent communication skills - clear, direct, and persuasive across technical and non-technical audiences
Even better...
  • Experience building or deploying AI/LLM systems in production
  • Have been a founder or founding engineer - you know what it means to balance craft, ownership, and speed
  • Familiarity with tools that power today's AI agents: eval frameworks, agent tooling, RAG pipelines, and prompt engineering
  • Prior experience with React, TypeScript, and/or Go
  • Previous roles where you interfaced with customers or led technical projects with external stakeholders

We want our benefits to reflect our values and offer the following to full-time employees:
  • Flexible (unlimited) paid time off
