Role Overview

We are looking for a senior, hands-on C++ engineer to join a small development team working on advanced engineering software. This position is best suited for someone who prefers deep technical work over people management, enjoys improving complex systems incrementally, and values close collaboration with a small group of experienced engineers.

This is not a managerial role. There are no direct reports and no expectation to transition into management. Success in this role comes from technical judgment, reliability, and collaboration, not from owning roadmaps or driving process.

Over time, this engineer will become a trusted technical counterpart to our senior developer—helping distribute technical load, providing thoughtful second opinions, and strengthening the long-term sustainability of the codebase.

What You Will Work On

• Maintaining, debugging, and enhancing a large, long-lived C++ codebase
• Improving performance, robustness, and test coverage in existing systems
• Implementing new features that integrate cleanly with established architecture
• Writing and maintaining automated unit and regression tests
• Investigating and resolving test failures and production issues
• Participating in code reviews and technical discussions with a small, distributed team

Most work involves understanding existing code deeply, not rewriting it.

Required Experience

• Strong proficiency in C++
  • Solid grasp of memory management, STL, and language features
  • Comfort navigating and modifying large, complex legacy codebases
• Experience debugging production software and diagnosing non-trivial defects
• Ability to work effectively in a small, hybrid-remote team
• Willingness to collaborate through code reviews and shared ownership
• U.S. citizenship or permanent residency

Strongly Preferred

• Windows development experience
• Visual Studio proficiency
• Experience with Azure DevOps or similar tooling
• Experience writing automated tests and debugging test failures

Helpful (But Not Required)

• C# / .NET
• VB / VBA
• FORTRAN
• QA or testing background
• CAD or 3D graphics software experience
  • Parasolid, HOOPS Visualize, MeshSim
• GUI development
  • C++ MFC and/or C# WPF

What We Value

• Engineers who prefer depth over breadth
• Thoughtful, respectful communication—especially in technical disagreement
• Comfort working alongside teammates with different strengths and communication styles
• Pride in making existing systems better, safer, and easier to maintain
