Software Engineer, Agent Dev Velocity Full Time

Notion helps you build beautiful tools for your life’s work. In today’s world of endless apps and tabs, Notion provides one place for teams to get everything done, seamlessly connecting docs, notes, projects, calendar, and email—with AI built in to find answers and automate work. Millions of users, from individuals to large organizations like Toyota, Figma, and OpenAI, love Notion for its flexibility and choose it because it helps them save time and money.

In-person collaboration is essential to Notion’s culture. We require all team members to work from our offices on Mondays, Tuesdays, and Thursdays, our designated Anchor Days. Certain teams or positions may require additional in-office workdays.

About The Role

Agent Dev Velocity builds the tooling and evaluation backbone that helps Notion ship high-quality AI faster and more safely. We build the infrastructure that makes AI evaluations easy to create, cheap to run, and hard to ignore, so engineers across the AI org can iterate with confidence.

In this role, you will work at the intersection of developer tooling, distributed systems, and measurement. You will build systems for running and maintaining evals at scale, and you will help create durable benchmarks and datasets that keep us honest about quality over time.

You will help evolve evals into a system, by enabling reusable eval workspaces and data-driven workflows that surface issues through data mining and continuous measurement.

What You’ll Achieve

• Build and improve scalable eval runners and harnesses that work locally, in CI, and on scheduled runs.
• Make it easy for engineers to add high-signal evals: better templates, fixtures, debugging tools, and clear workflows.
• Build and maintain benchmark and dataset tooling (curation pipelines, versioning, artifact management, and regression tracking).
• Improve reliability and observability for eval execution (retries, idempotency, cost and latency visibility, and failure triage).
• Partner closely with AI product, AI platform, and infrastructure teams to integrate evals into day-to-day shipping workflows.

Skills You’ll Need To Bring

• Strong software engineering fundamentals and experience shipping production systems.
• Proficiency with TypeScript/Node and/or Python.
• Experience building reliable systems in distributed environments (queues, retries, idempotency, and backfills).
• Comfort working with data pipelines (batch processing, data quality, versioning, and reproducibility).
• Practical experience designing measurement or evaluation systems (LLM eval experience is a plus, but strong testing and benchmarking instincts also apply).
• You don’t need to be an AI expert, but you’re curious and willing to adopt AI tools to work smarter and deliver better results.

Nice To Haves

• Experience building developer tooling (CLI tools, CI integrations, or internal platforms).
• Familiarity with LLM evaluation techniques (rubrics, human review loops, dataset curation, and regression detection).
• Experience collaborating across teams to roll out new workflows and drive adoption.

We hire talented and passionate people from a variety of backgrounds because we want our global employee base to represent the wide diversity of our customers. If you’re excited about a role but your past experience doesn’t align perfectly with every bullet point listed in the job description, we still encourage you to apply. If you’re a builder at heart, share our company values, and enthusiastic about making software toolmaking ubiquitous, we want to hear from you.
