Title: Principle Software Engineer

Location: Norwalk, CT

Salary - $150,000 – $180,000 +Bonus

Right now, we're looking for a Senior Principal Software Engineer to take a leading role in architecting and delivering the software that powers our next generation of machine control systems. This is a hands-on, senior-level position where you'll have real ownership, technical influence, and direct impact on the business.

Why This Role Stands Out:

  • High Visibility: You won't be buried in code no one sees — this role is front and center across engineering, product, and executive teams.
  • Complex, Real-World Problems: This isn't app development. You'll be building control software for high-speed, precision-driven systems that integrate mechanical, electrical, and software components.
  • Stability + Innovation: Join a company that's been around for decades — but continues to evolve. xhyhwjd The tech is serious, the teams are strong, and the roadmaps are ambitious.
  • Long-Term Career Growth: This isn't a stepping-stone job. It's a long-term opportunity to lead, grow, and shape the future of how our machines performance

What You'll Do:

  • Design and develop real-time control software in C++ for large-scale, high-performance electromechanical systems
  • Lead cross-functional efforts across software, hardware, systems, and manufacturing
  • Guide architecture and technical strategy for multiple products and platforms
  • Debug and optimize at the system level — from code to motion control to hardware integration
  • Play a key role in roadmap planning and technical decision-making

What You Bring:

  • 10+ years of experience in object-oriented software design and full-lifecycle development
  • Deep hands-on experience in C++ and real-time operating systems (such as RTX)
  • Strong background in mechatronics, machine control, or similar system-level environments
  • Ability to lead multidisciplinary teams and drive projects through ambiguity to delivery
  • Excellent communication skills — both with engineers and stakeholders
  • BS or MS in Computer Science or a related field

Bonus Points:

  • Experience with motion or servo motor control
  • Exposure to .NET, Java, or ASP.NET
  • Background in SQL Server, Oracle, or web-based service architecture
  • Knowledge of industrial automation or paper-handling/mailing systems
