Senior Software Engineer – C++ (Engineering

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.

• 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.

• 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

• Experience with Azure Dev Ops or similar tooling
• Experience writing automated tests and debugging test failures

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

• 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
