</ul>
<ul>
<li>Partner closely with electrical engineering, camera pipeline owners, and systems teams to define interfaces, unblock integration, and keep the camera stack stable as the device evolves.</li>
</ul>
<p><strong><strong>You might thrive in this role if you:</strong></strong></p>

<li>Hands-on understanding of common camera hardware interfaces (for example, MIPI CSI and sensor control buses) and the practical realities of bring-up, including power, reset, clocking, and sequencing.</li>
</ul>
<p><strong>Preferred Qualifications</strong></p>
<ul>
<li>Experience with common mobile or embedded SoC camera stacks and vendor frameworks.</li>
</ul>
<ul>
<li>Experience integrating and debugging hardware acceleration blocks adjacent to camera pipelines, such as video encode and decode paths.</li>
