Job description

About the Role
Our client is a global leader in fire and life-safety systems, delivering mission-critical building safety solutions across North America. As part of the engineering team, you'll own the Windows-based configuration software that technicians and engineers rely on to program, validate, and deploy fire alarm control panels in the field. This is a hands-on, product-critical role where software quality has direct real-world safety implications — every configuration your code validates protects lives and property.

What You’ll Do

• Design, develop, and maintain Windows configuration software (C++ and C#/.NET) for fire alarm control panels.
• Build and enhance features for panel programming, device configuration, and validation of configuration data.
• Work across the boundary between the desktop configuration tool and embedded panel firmware, including communication over serial and IP protocols.
• Implement robust data validation to ensure generated configurations meet fire and life-safety requirements.
• Debug and troubleshoot issues spanning configuration software, panel communication, and data integrity.
• Write unit and integration tests, participate in code reviews, and contribute to a maintainable, well-documented codebase.
• Collaborate closely with firmware, hardware, QA, and product teams within an Agile delivery process.
• Participate in sprint planning, backlog refinement, and retrospectives, contributing to continuous improvement of the team's engineering practices.
• Support root-cause analysis for field-reported issues, working cross-functionally to reproduce, diagnose, and resolve defects.
• Contribute to technical documentation, including design specs, API references, and configuration validation rules.
• Mentor junior engineers and share knowledge across the desktop/firmware boundary as the team scales.

Profile Requirement

• Bachelor's degree in Computer Science, Software/Computer Engineering, or a related field.
• 5–8 years of professional software development with strong hands-on experience in both C++ and C#.
• Solid Windows desktop development with .NET (WinForms and/or WPF).
• Strong fundamentals: object-oriented design, data structures, algorithms, and systematic debugging.
• Experience with communication protocols (serial / TCP-IP) between an application and a device.
• Version control and CI workflows (Git and/or Azure DevOps).
• US work authorization and ability to work onsite in Westford, MA, 3 days per week.
• Professional fluency in English.

Nice to Have

• Prior experience in a regulated or safety-critical industry (fire/life safety, medical devices, industrial controls, automotive).
• Familiarity with embedded systems concepts, even without direct firmware development experience.
• Exposure to static analysis, code coverage tooling, or safety/compliance standards (e.g., UL, NFPA).

Why choose us

• An international community bringing together more than 110 different nationalities
• An environment where trust is central: 70% of our leaders started their careers at the entry level
• A strong training system with our internal Academy and more than 250 modules available
