The Role

We're after a Performance Engineer whose idea of a good day is an autonomy-rich pull request that closed three tickets and opened zero. Join McKinsey & Company as a freelance Performance Engineer and take real ownership of Next.js work while earning $54,000 - $84,000 and growing your craft.

Key Responsibilities

  • Sit with technology users in Tampa to learn what the Next.js tool really needs
  • Reverse-engineer the relentlessly curious AWS format McKinsey & Company inherited and never documented
  • Negotiate AWS tradeoffs with product when McKinsey & Company timelines and reality collide
  • Drive the Ruby on Rails incident postmortem that stops the Tampa outage from recurring
  • Land Team Leadership performance wins McKinsey & Company can measure in FL retention numbers

What You'll Bring

  • Familiarity with Ruby on Rails and related tools or frameworks
  • Comfort working in a fast-paced, empowering environment
  • Comfort owning the unglamorous middle of a freelance project
  • Proven track record delivering results as a junior Performance Engineer
  • Self-motivated and able to work independently with minimal oversight

McKinsey & Company grew out of a Tampa, FL research lab and never lost its human-first, question-everything approach to Ruby on Rails. People here care as much about how we work together as what we ship.

You'll receive $54,000 - $84,000, a hybrid schedule, and a personalized development plan tailored to your technology career goals.

Reopened and refreshed, the search for a junior candidate runs hot today.

Apply today, and the next time we post about this technology win, it could be yours.
