Danbury CT, United States Smith Arnold Partners Full time

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. This is a role for engineers who want to build the core — not just bolt things on. If you want to own complex systems, influence product direction, and work in an environment where your expertise is valued and your career can thrive — let's talk. Apply now or message us directly for a confidential conversation. 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. Principle Principal Software Engineer Location: Norwalk, CT Salary - $170.000 – $190,000 +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
