[Hiring] Senior Software Engineer @ConnectWise

Role Description

You will be a senior engineer on the x360Sync team at ConnectWise, owning development of the macOS agent — a native desktop application at the heart of the x360Sync backup and file sync product. The application is primarily written in C++, with Swift and Objective-C used for macOS-native components. You will be stepping into a mature codebase with real ownership and scope from day one.

Key Responsibilities

• Design, implement, and maintain features in the x360Sync macOS agent, working primarily in C++ with Swift and Objective-C for platform-native integrations
• Debug and resolve production issues, including deep-dive investigation across the application stack and macOS system APIs
• Participate in architecture and design discussions, contributing technical recommendations grounded in macOS platform best practices
• Write clean, well-tested code and take part in code reviews — both giving and receiving constructive feedback
• Collaborate with product managers, QA engineers, and cross-functional teams to deliver features on schedule without cutting corners on quality
• Contribute to improving engineering standards, internal tooling, and development processes
• Help scope and break down complex problems into well-defined tasks for yourself and the broader team
• Document technical decisions, system behavior, and processes clearly for teammates and future contributors

Qualifications

• Solid professional experience writing C++ in a production environment
• Strong working knowledge of macOS internals, frameworks, and platform APIs (e.g. NSFileProvider, FSEvents)
• Proficiency in Swift and/or Objective-C for macOS-native development
• Experience debugging complex, multi-threaded, or multi-process applications
• Experience with software development workflows, including version control (Git), code review, and CI/CD pipelines
• Strong written and verbal English communication skills — you'll work with distributed teams and will need to articulate technical ideas clearly
• Ability to work independently and manage your own priorities in a remote or hybrid environment
• Comfortable working in an established codebase with existing design decisions you didn't author

Nice-to-Have Qualifications

• Experience with file sync, backup, or storage-related products
• Familiarity with Windows desktop development (the x360Sync agent also has a Windows counterpart)
• Exposure to cross-platform C++ codebases targeting both macOS and Windows
• Experience working in an Agile/Scrum team environment
• Background in developer tooling, performance profiling, or low-level system programming on macOS

Why Join the x360Sync Team

The x360Sync team works on software that businesses genuinely depend on — keeping their files safe and in sync. You won't be building another internal dashboard; your work ships to real customers and has a clear, direct impact. The team values technical rigor, honest communication, and getting things done without unnecessary ceremony. If you enjoy owning hard problems in a native desktop environment and want your expertise in C++ and macOS to be the main event rather than a footnote, this is the role for you.
