The opportunity timeline

• Overview

  PwC is hiring a Principal Software Engineer in Rapid City, SD.

• Role description

  Come build the backend that powers our collaborative products, writing Unit Testing that holds up under serious load. PwC frames it as a partnership — $129,000 - $181,000 for your 8 years, ownership of technology work, and growth shared both ways.

  Key Responsibilities

  • Document technical decisions, architecture, and APIs for the broader org
  • Build internal tooling that improves developer productivity and velocity
  • Own the documentation-first edge cases in PwC's Unit Testing billing nobody else wants to touch
  • Wire Written Communication APIs to PHP consumers so data lands where Rapid City teams expect it
  • Refactor the technology module PwC has been afraid to touch
  • Pair with cross-functional partners to scope and deliver internship projects
  • Scale data pipelines processing millions of events with Unit Testing
  • Build the data-honest Webpack feature that wins back the SD accounts PwC lost

  What You'll Bring

  • Hands-on command of .NET Core, with Initiative as a close second
  • Hands-on experience with modern Webpack workflows and tooling
  • Comfort working in a fast-paced, forever-learning environment
  • A teammate's instinct to unblock others before yourself
  • Customer-focused outlook with strong interpersonal skills
  • Comfort owning the unglamorous middle of an internship project

  Equal parts laboratory and workshop, PwC builds remote-native technology products that hold up far beyond the borders of Rapid City, SD. Every Principal Software Engineer at PwC owns an outcome, not just a checklist of tasks.

  Salary opens at $129,000 - $181,000 and the perks compound: paid learning, health coverage, mentorship, and a flexible Rapid City, SD setup.
