• Lead investigations into failed or delayed migrations, conduct root cause analysis, and implement follow-up improvements to prevent recurrence.

• Support and mentor fellow engineers, including Migration Operations Engineers, through code reviews, collaborative programming, and constructive feedback. Share knowledge generously within the team.

• Collaborate closely with Onboarding, Support, Product Managers, and other engineering teams to coordinate timelines, manage customer expectations, and align technical delivery with the broader onboarding strategy. Clearly communicate risks, blockers, and status updates to both technical and non-technical stakeholders.
