[Hiring] Model Behavior, Product @The Browser Company

Role Description

At the Browser Company, you will play a crucial role in shaping how Dia interacts with users. This is a hands-on role at the intersection of product and AI engineering:

• Define Dia’s intended behavior.
• Ship prompt and code changes that deliver it.
• Own evals that measure quality and cost.

The work spans the full stack of modern AI product development:

• Prompting
• Tools
• Model selection
• Agent harnesses
• Evaluation systems

You'll report to our Model Behavior Lead and work closely with engineering and product. You'll have high impact and own problems end to end:

• Understanding what users need.
• Deciding the right approach.
• Shipping the change.
• Proving it worked.

Overall you will:

• Shape Dia's AI experience.
• Figure out what the right behavior is for users, then find the best path to it — a prompt change, a new tool, a different model or harness, better evals, or a spec that aligns the team.
• Ship every week.
• Improve systematically.
• Build the tools that make us faster.
• Keep us at the frontier.

Recent examples of projects the Model Behavior team led:

• Morning Brief: Prototyped our best performing feature of all time.
• Chat architecture: Our move to an agent harness began as a prototype over our winter shutdown.

Qualifications

• 4+ years of experience in product, design, or adjacent builder roles.
• Hands-on experience taking a product from concept to its initial release (v1). Previous experience as a founder is a plus.
• You think in systems.
• You work inside AI tools daily.
• You want to be an IC.
• You're here to make an impact.
• We’re primarily focused on hiring in North American time zones and require that folks have 4+ hours of overlap time with team members in Eastern Time Zone.

Requirements

• Ability to take an ambiguous problem, break it into something measurable, and design the evals to steer it.
• Navigate when to decide on a short improvement fix versus investing in systematic fixes.
• Articulate the reasoning behind your tooling choices.
• Put up multiple PRs weekly.

Benefits

• Total compensation package includes base salary, equity, and benefits.
• The annual salary range for this role is $200,000 - $275,000 USD.
• Wide range of perks and benefits designed to support you and your family.

Location: We’re a remote-friendly company and can hire in any country where Atlassian has a legal entity.
