Software Engineer, Product - Testing

What you’ll do

We work in small, autonomous teams oriented around customer problems. Here are some examples of what you’ll work on :

Agent Architecture : What primitives do we need to build agents that are steerable and verifiable, but also conversational and empathetic? How do we future-proof this as LLMs evolve?

Retrieval : How do we ground answers in a customer’s knowledge base? How do we use retrieved context conversationally, handling cases where the answer is unclear or needs clarification from the user?

Evals : How do we measure an agent’s quality? How do empower our customers to improve agent quality?

Voice : How do we make our chat agents “just work” over the phone? How do we deliver lifelike conversations at low latency?

Simulation & Benchmarking : How can we craft a simulation platform to test AI agents against every real-world scenario imaginable?

Content Management : How do we create intuitive, no-code tools that allow anyone to guide and test AI agents?

Agent Development Lifecycle : How do we adapt traditional software development methodologies to accommodate AI agents’ non-deterministic behavior, natural language interactions, and reliance on large language models

Generative Agent Development : How do we accelerate agent creation using generative tools like Cursor and Claude Code? Can we build self-improving systems based on real-world interactions, customer-driven feedback, and self-play?

Our values

Trust : We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work.

Customer Obsession : We deeply understand our customers’ business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it.

Craftsmanship : We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isn’t right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve.

Intensity : We know we don’t have the luxury of patience. We play to win. We care about our product being the best, and when it isn’t, we fix it. When we fail, we talk about it openly and without blame so we succeed the next time.

Family : We know that balance and intensity are compatible, and we model it in our actions and processes. We are the best technology company for parents. We support and respect each other and celebrate each other’s personal and professional achievements.
