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:

\n
• High Visibility: You won’t be buried in code no one sees — this role is front and center across engineering, product, and executive teams.
\n
• 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.
\n
• Stability + Innovation: Join a company that’s been around for decades — but continues to evolve. The tech is serious, the teams are strong, and the roadmaps are ambitious.
\n
• 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
\n

What You’ll Do:

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

What You Bring:

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

Bonus Points:

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