<li>Working closely with engineers across multiple product teams to solve shared technical challenges</li>
<li>Leading technical initiatives and helping raise the engineering bar across the organization</li>
<li>Exploring how AI can improve engineering workflows and developer productivity</li>
<li>Building reliable guardrails and tooling around AI-assisted software development</li>
</ul>
This role is ideal for someone who enjoys making other engineers more productive, thinking about long-term technical health, and solving engineering problems that have impact across multiple teams.
<h2 class="jobSectionHeader">
Our humble expectations</h2>

We're looking for engineers who have experience with most of the following:
<ul>
