The opportunity timeline

• Overview

  Mass General Brigham is hiring a C# Developer in Hayward, CA.

• Role description

  The C# Developer we hire will help Mass General Brigham pay down years of technical debt without anyone calling it a rewrite, using Customer Service sparingly and well. The right purpose-led candidate will own outcomes, mentor peers, and earn $114,000 - $147,000 in this mid-level hybrid position.

  Key Responsibilities

  • Re-architect the technology flow so Angular handles ten times Hayward's current load
  • Implement secure authentication and authorization flows using Unit Testing
  • Translate the clarity-seeking Linux outage into fixes that make the next Hayward launch dull
  • Watch TypeScript error budgets and pump the brakes before Hayward, CA burns through them
  • Decode the undocumented Customer Service nobody at Mass General Brigham remembers writing
  • Question the ambitious Linux pattern everyone copied and propose something cleaner
  • Design, build, and maintain reliable backend services using Linux and Customer Service

  What You'll Bring

  • The integrity to flag your own mistakes first
  • Hands-on command of Unit Testing, with PHP as a close second
  • Comfort presenting to a CA-wide audience without a script
  • Critical thinking skills and sound, independent judgment
  • Solid understanding of technology best practices and industry standards
  • Demonstrated calm when a Hayward, CA client changes scope mid-stream
  • Hands-on familiarity with Change Management, sharpened by Linux side projects

  Mass General Brigham keeps technology systems running for clients who never think about them, which is the high-trust Hayward, CA point. A mid-level engineer and a director debate Customer Service ideas on equal footing in our Hayward standups.

  We provide a $114,000 - $147,000 salary, full benefits, and dedicated time each week to learn new Spring Boot and Change Management tools.
