Senior Product Engineer

Role Description

This role sits on our Agents team — the group building the AI-powered experiences our customers use every day. It's where large language models stop being a demo and become a dependable part of the product: answers, drafts, and assistive features that have to be fast, trustworthy, and genuinely useful in front of real customers.

• Ship customer-facing AI features across the full stack.
• Build the experience and what's behind it — LLM-backed flows, retrieval (RAG) and embeddings, and agentic tool-calling — through to a fast, accessible, well-crafted UI.
• Treat AI output as something you verify, not assume.
• Build evaluations, guardrails, and monitoring into AI features so quality is measurable and holds up in production.
• Sweat the front-end craft.
• Stay close to customers.
• Own outcomes, not just output.
• Co-author the solution.
• Own production readiness from the start.
• Use AI tools every day as part of your craft.
• Help us hire.

Qualifications

• Strong, full-stack-capable engineer with a frontend center of gravity.
• Substantial JavaScript/TypeScript and React experience.
• Experience building real things with LLMs — not just prototypes.
• Comfortable with retrieval (RAG), embeddings, prompt/context engineering, and agentic/tool-calling patterns.
• High bar for AI quality.
• Genuinely fluent with AI coding tools.
• Customer-fluent.
• Own outcomes.
• Take real ownership of the full development lifecycle.
• Communicate clearly in writing and in conversation.

Requirements

• Experience making LLM features production-grade: latency/cost tuning, fallbacks and circuit breakers across providers, moderation/safety, and handling sensitive data responsibly.
• Familiarity with evaluation/observability tooling for AI.
• Design sensibility — comfort partnering closely with designers.
• Experience in customer support, productivity, or other tools where trust and reliability are the product.

Benefits

• Competitive salary and an internal, transparent salary formula based on market data.
• Flexible time off – you choose the holidays and vacations that make sense for you.
• 12 weeks of fully paid parental leave for all new parents, including adoption and foster care.
• A home office stipend to help you get set up and productive.
• A co-working stipend up to $300 a month if you choose to work out of your house.
• A yearly professional development stipend of $1,800 to help you grow in your craft.
• Top tier health insurance for you and your dependents if you’re in the U.S. or Canada.
