About the Role

  • FileCloud is looking for a highly skilled Senior Software Engineer, Client Applications (macOS) to join our team in Riyadh, the Kingdom of Saudi Arabia.
  • You will work on the core sync and OS integration layer of FileCloud Desktop on macOS.
  • This role is fully office based and will require working in our KSA office with other members of the remote FileCloud team.

About the Product & Company

  • FileCloud is a hyper secure EFSS platform providing compliance, data governance, data leak protection, data retention and digital rights management.
  • FileCloud is a leader in content governance and collaboration for unstructured data, trusted by Global 1000 enterprises, educational institutions, government organizations, and service providers.
  • FileCloud’s product portfolio also includes Signority, a Canadian based e signature and document workflow platform.

Key Responsibilities

  • Design, implement, and maintain system level components for FileCloud Desktop on macOS in Swift (Swift 5.5 and higher).
  • Work with Apple’s File Provider framework, FileProvider domain management, and Endpoint Security/ESClient to handle filesystem events, placeholders, hydration/dehydration, and user actions.
  • Implement and maintain gRPC services and clients (and JSON/REST style APIs where applicable) that connect system components to higher level layers (Electron/TypeScript UI, server side services).
  • If you have Windows experience, contribute to Windows system components in modern C++ using the Windows Cloud Files API (CFAPI).
  • Develop and maintain unit tests (gtest) and integration tests (Python + pytest) to build and extend automated coverage.
  • Integrate with Finder for file badges, context menus, and other extensions using File Provider and PlugInKit.
  • Use tools like Xcode, LLDB, and Instruments to debug complex issues in production like environments.
  • Contribute to build and CI/CD pipelines (e.g., Jenkins, Xcode build system, Swift Package Manager, shell scripting).

Key Skills & Experience: Swift / macOS system programming

  • Strong commercial experience with Swift (Swift 5.5 and higher), including async/await, actors, and structured concurrency.
  • Solid knowledge of macOS internals: processes, Grand Central Dispatch, Swift concurrency primitives, synchronization, I/O, memory, security entitlements.
  • Hands on experience with macOS/POSIX and Apple framework APIs (Foundation, FileProvider, EndpointSecurity, XPC).
  • Experience with multithreaded and asynchronous code using Swift structured concurrency (async/await, actors, Tasks).

Filesystems, sync & networking

  • Good understanding of filesystem behavior: notifications, caching, metadata, locking, renames, symlinks/junctions.
  • Experience in or strong interest in sync/backup clients, cloud storage, or related areas.
  • Familiarity with networked applications (HTTP/HTTPS, TLS, proxies) from a developer perspective.

APIs, testing & debugging

  • Experience with RPC / typed APIs (e.g. gRPC, JSON/REST, or similar) and willingness to work with gRPC daily.
  • Hands on experience writing automated tests: unit tests in gtest and integration tests in Python + pytest.
  • Strong debugging skills on macOS using Xcode, LLDB, Instruments, and system tools (Console.app, fs usage, log stream).

Collaboration & work style

  • Ability to work independently and take ownership of complex subsystems.
  • Comfortable collaborating with UI (Electron/TypeScript/Vue), QA, Windows (C++) engineers, and backend services teams.
  • Good communication skills in English and prior experience in a globally distributed team.
  • Comfortable using AI coding assistants (e.g. Claude Code, GitHub Copilot, Cursor, or similar) as part of a daily development workflow for code generation, review, debugging, and documentation.

Nice to have / Learn on the job

  • Experience with Apple File Provider framework or other virtual filesystem/sync APIs (e.g. Windows CFAPI).
  • Experience building macOS installers: PKG/DMG creation, notarization, hardened runtime, and Gatekeeper compliance.
  • Familiarity with Swift Package Manager (SPM) for dependency management.
  • Experience with XPC services for secure inter process communication on macOS.
  • Familiarity with macOS app sandbox, entitlements, code signing, and the Apple notarization pipeline.
  • Experience with Jenkins or similar CI systems.
  • Familiarity with large language model APIs (e.g. OpenAI, Anthropic) or machine learning concepts as background knowledge.
  • Scripting skills in shell scripting on macOS/Linux (and/or basic PowerShell for cross platform CI tasks).
  • Background in cloud storage, sync clients, security/endpoint products, or distributed systems.
  • Awareness of security best practices when working at the OS and filesystem layer.

What We Offer

  • Be part of a team of passionate, committed individuals dedicated to building a world class product.
  • Dedicated time for training and education opportunities.
  • A mentorship model wherein your mentor and team support your development.
  • A competitive salary with an annual bonus.
  • Onsite work with flexible hours that fall outside of the companywide core hours of 9am 12pm (US Eastern Standard Time).
  • 20 days of paid time off which increases by a further 2 days after 3 years of service and 3 days after 5 years of service (in addition to 10 public holidays in your country).
  • Paid day off on your birthday or on an alternative day if your birthday falls outside a normal working day.
  • Paid day off to volunteer with the charity of your choice.
  • Paid monthly internet cost, as well as lunch and wellbeing stipend provided.
  • Reimbursement of all hardware costs associated with the role.
  • Please note that we conduct background security checks for everyone joining our team.
