Applied AI Engineer

About Us

We're on a mission to empower builders. Our docs platform serves 100 million+ developers every year and powers documentation for 20,000+ companies, including Anthropic, Microsoft, PayPal, Spotify, Coinbase, X, and over 20% of the last YC batch. We recently passed 65 employees and raised a $45 million Series B led by A16Z and Salesforce Ventures. Each new hire has a huge impact on shaping the company's trajectory.

We value learning velocity, grit, and unapologetically unique personalities. We grew in value faster than headcount and we’re looking to align the two quickly.

Responsibilities

• Building AI products end to end: Designing and shipping customer-facing AI experiences, from agent orchestration and tool use to the interfaces and backend systems that support them
• Developing reliable agents: Building agent loops that reason over complex context, call tools, recover from failures, and complete long-running tasks
• Evaluating and improving performance: Creating evals, analyzing failures, and hill-climbing on prompts, context, models, tools, and product flows
• Shipping across the stack: Building the APIs, data pipelines, interfaces, and production infrastructure needed to turn promising prototypes into polished products

Requirements

• At least 4 years of professional software development experience
• Deep experience building production systems with language models, including agent loops, tool use, retrieval, prompting, and structured outputs
• Comfortable owning production software across frontend, backend, APIs, databases, and infrastructure
• Experience leading complex projects from experimentation through production and thrive when defining solutions rather than following a spec
• Strong product intuition and care about the “why” as much as the “how” when building user-facing software
• Eagerness to talk directly with customers and use those insights to shape what we build
• Experience mentoring other engineers, sharing technical knowledge, and helping teammates grow
