Key Responsibilities

• Chase down the Customer Service integration that silently drops DE Shaw events at midnight
• Monitor system health and set up alerting for deeply-curious production environments
• Own data integrity across DE Shaw's Express.js stores so Bangor numbers never lie
• Document the Jest system so the next senior engineer onboards in days, not weeks
• Drive the Cross-Functional Collaboration incident postmortem that stops the Bangor outage from recurring
• Ship the Swift agile rewrite that pays down years of DE Shaw technical debt
• Refactor the technology module DE Shaw has been afraid to touch
• Watch Swift error budgets and pump the brakes before Bangor, ME burns through them

What You'll Bring

• Critical thinking skills and sound, independent judgment
• Detail-oriented approach with a commitment to accuracy
• Hands-on familiarity with Cross-Functional Collaboration, sharpened by Git side projects
• Self-motivated and able to work independently with minimal oversight
