Software Engineer, Agent

About the Job

At Sierra, we're creating a platform to help businesses build better, more human customer experiences with AI. We are primarily an in-person company based in San Francisco, with growing offices in Atlanta, New York, and London.

What you'll do:

• Design and deliver production-grade AI agents: Build and ship highly performant, reliable, and intuitive AI agents.
• Drive the Agent Development Life Cycle (ADLC): Have complete ownership from pilot to deployment, defining ADLC best practices.
• Partner with large enterprises and cutting-edge startups: Work directly with leaders to understand challenges and build solutions.
• Build the future of the platform: Surface unmet needs, prototype new tools, and shape the future of AI agent development.

Example Projects:

• 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:

• 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

These benefits are further detailed in Sierra's policies and are subject to change at any time, consistent with the terms of any applicable compensation or benefits plans. Eligible full-time employees can participate in Sierra's equity plans subject to the terms of the applicable plans and policies.
