Lead Software Engineer, Customer Experience & Reliability

The Mission

Financial advisors rely heavily on Morningstar's Direct Advisory Suite and when software breaks, they need instant resolution. Our Delight team transforms support from cost center into competitive advantage by combining hardcore production engineering with AI-enhanced diagnosis to deliver service excellence competitors can't replicate.

As a Lead Software Engineer for Customer Experience & Reliability, you are a technical leader and customer advocate responsible for driving the resolution of complex, cross-system production issues.

This role offers a unique mix of technical leadership and hands-on engagement, allowing you to influence outcomes while staying close to the technology. You'll partner closely with a Senior Engineering Manager to ensure:

• The right problems are prioritized and addressed
• Engagement within the team
• Root causes are clearly identified
• Follow-up actions are effectively executed

You will remain technically engaged in reading code, analyzing logs, and troubleshooting issues, but your primary impact will come through ownership, coordination, and sound technical judgement.
