Advanced Software Engineer

Honeywell is evolving the software platform that powers mission critical building security and automation systems used at global scale. This role sits at the core of that evolution—owning complex software systems, influencing architecture decisions, and helping modernize a mature, high impact platform where reliability and correctness truly matter.
 

This is a hands on senior engineering role for someone who wants meaningful technical ownership, not a coordination or people management position.
 

You will report directly to our Engineering Manager and you’ll work out of our Atlanta, GA location on a Hybrid work schedule.
 

KEY RESPONSIBILITIES

• Design, build, own and maintain core platform components, from implementation through deployment, diagnostics, and long term evolution.
• Write and review high quality C++ / C# code with a strong emphasis on correctness, performance, and maintainability.
• Contribute to technical design and architectural discussions driving improvements in scalability, resiliency, performance, operational simplicity, and developer productivity.
• Tackle hard system failures—including concurrency issues, performance degradation, data consistency problems, and integration failures across services and devices. 
• Establish patterns and best practices for testing, observability, and debuggability in complex systems. 
• Collaborate closely with other engineers, QA and product partners in an Agile, multi site development environment.
• Communicate technical complexity clearly providing pragmatic estimates, design tradeoffs, and progress updates when needed.
• Coding focus: This role is primarily hands on engineering. Architectural thinking and collaboration are essential, but shipping high quality software is the core expectation.
   

YOU MUST HAVE

• 6+ years of professional Software Development experience building and debugging production systems in 
• Windows development and deployment platform
• Strong proficiency in C++, VC++, C#, Messaging Systems within Windows based environments. 
• Experience working with relational databases, ideally MS SQL Server. 
• Solid understanding of Windows internals and Windows development technologies. 
• A disciplined approach to debugging, testing, and system analysis. 
• Experience using modern developer tooling (e.g., Copilot) to improve productivity, code quality, or test coverage.
   

WE VALUE

• Experience with system level debugging, reverse engineering, or advanced diagnostic tools. 
• Background in architecture evolution of long lived platforms. 
• Exposure to hardware–software integration, driver development, or low level interfaces. 
• Strong testing mindset (TDD or similar) and experience with secure coding practices. 
• Ability to balance technical depth with clear communication across engineering and non engineering audiences. 
• Familiarity with building automation, security systems, or other safety critical domains.
