Senior Principal Software Engineer

Senior Principal Software Engineer – Real-Time Systems | High-Impact, High-Visibility Role
If you’re an experienced software engineer who wants to build things that actually move — fast, accurately, and at scale — this is a role worth considering.
We’re a well-established global tech organization that builds the software and systems behind some of the most advanced, high-speed electromechanical equipment in the industry. Our technology helps run the operations behind critical communications and logistics around the world.

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. 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 perform.

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

This is a role for engineers who want to build the core — not just bolt things on.
