Software Engineer, Agent (Spanish speaking)

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 Spanish and English

• Experience building and scaling end-to-end production systems
