Honeywell’s Security and Access Solutions business provides high-value security products and services that are critical for buildings around the globe. Building operators and security teams across dynamically evolving verticals depend on our software platforms for access control, intrusion detection, and locking solutions to help create safer and more efficient facilities. 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.
This role is primarily hands‑on engineering. Architectural thinking and collaboration are essential, but shipping high‑quality software is the core expectation. As part of the engineering team, you will work in a continuous delivery environment and contribute to features that directly impact on our customers daily.
You will participate in feature planning and design sessions, implement software solutions, assist with test plans and documentation, and maintain those solutions. The ideal candidate will demonstrate strong functional programming skills and excellent communication to discuss her/his ideas with relevant stakeholders around the globe.
- 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.
Must Have:
- 4+ 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, multi-threaded programming within Windows‑based environments.
- Experience working with relational databases, ideally MS SQL Server.
- Solid understanding of Windows internals and Windows development technologies.
- Understanding and usage of Open telemetry.
- A disciplined approach to debugging, testing, and system analysis and it associated tools.
- Experience using modern developer tooling (e.g., Copilot) and best practices 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.
