Tenth Revolution Group



We’re partnered with a well-established, highly respected private equity firm to hire a Principal Fullstack .NET Engineer for a hands-on, high-impact role within their technology team.

This is an opportunity to architect and build sophisticated financial systems that directly support investment strategy and operations — in a firm that values engineering excellence and modern Microsoft technologies.

This is a deeply technical role focused on engineering excellence and long-term platform strategy.

As a Principal Engineer, you will:


  • Architect, design, and build enterprise-grade financial applications
  • Develop backend systems using modern versions of .NET (.NET 6/7/8)
  • Build and maintain dynamic front-end applications using Angular
  • Lead technical design discussions and influence architecture decisions
  • Work closely with investment, operations, and business stakeholders
  • Mentor junior developers (while remaining fully hands-on — no people management)

What We’re Looking For

  • Extensive experience building applications with modern .NET + Angular
  • Background in private equity, financial services, or banking
  • Deep familiarity with Microsoft-based environments
  • Experience deploying and maintaining applications in Azure
  • Strong understanding of secure, scalable system design
  • Nice-to-have: Experience building dashboards or reporting solutions in Power BI


The Environment

  • Onsite 5 days/week in a collaborative, high-performance office environment
  • Onsite cantina and high-quality office amenities
  • Regular, company-sponsored social events
  • Stable, profitable private equity platform with long-term growth strategy
  • Engineering team that values ownership, craftsmanship, and mentorship

This is ideal for a senior/principal-level engineer who wants to:

  • Stay fully hands-on
  • Work in a sophisticated investment environment
  • Join a firm with stability, resources, and strong leadership

If you’re interested (or know someone who might be), feel free to message me directly or apply here.
