Advanced Software Engineer

Job Description

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.

• Design, build, own and maintain core platform components, from implementation through deployment, diagnostics, and long‑term evolution.
• Write and review high‑quality C++ and C# code with a strong emphasis on correctness, performance, and maintainability.
• Contribute to technical design and architectural discussions driving improvements in scalability, resilience, 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 trade‑offs, 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.

• 6+ years of professional software development experience building and debugging production systems in Windows development and deployment platform.
• Strong proficiency in C++, VC++, C#, and 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.

• 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.

In addition to a competitive salary, leading‑edge work, and developing solutions side‑by‑side with dedicated experts in their fields, Honeywell employees are eligible for a comprehensive benefits package. This package includes employer‑subsidized medical, dental, vision, and life insurance;
Short‑Term and Long‑Term Disability; 401(k) match;
Flexible Spending Accounts;
Health Savings Accounts; EAP; and educational assistance; parental leave; paid time off (vacation, personal business, sick time, and parental leave); and 12 paid holidays.
