Job Description:

What you'll do

  • Own customer-facing features end-to-end, across the Swift/SwiftUI client and the Rust backend that powers it.
  • Build and evolve the Finder-grade file browser, bridging AppKit (NSCollectionView, NSTableView, NSBrowser, NSPathControl) into SwiftUI where SwiftUI alone won't cut it.
  • Design and evolve the gRPC / Protobuf contract between the app and the agent as the product grows.
  • Work in a large Rust workspace of shared crates async/tokio, fault-tolerant, built to run reliably on customers' machines.
  • Ship native: code signing, entitlements, notarization, sandboxing, launchd services, and real observability (os.Logger and friends).
  • Balance speed, performance, and future scalability and know which one matters most for the change in front of you.

What you bring

Must-have (core, non-negotiable)

  • Swift + SwiftUI with real AppKit experience. The Finder-grade file browser leans heavily on AppKit (NSCollectionView, NSTableView, NSBrowser, NSPathControl via NSViewRepresentable), so hands-on AppKit experience matters here.
  • Rust async/tokio, comfortable in a large workspace of shared crates.
  • Strong concurrency and async on both sides: Swift async/await (MVVM, @Observable) and Rust tokio/futures.
  • gRPC / Protocol Buffers designing and evolving a versioned RPC contract as clients evolve.
  • macOS platform fluency launchd services, code signing, entitlements, notarization, sandboxing, os.Logger.

Where you could make a big impact

Strong candidates will have some of these and going deep in any one is a way to have outsized impact on the product.

  • GraphQL client work (Apollo iOS or equivalent normalized caching, codegen, subscriptions).
  • Filesystem internals FUSE / FSKit / WinFSP, NFS mounts, FSEventStream / inotify-style change observation. This is the hardest-to-hire and highest-leverage skill on the team.
  • P2P and networking systems WebRTC, NAT traversal, signaling, WebSockets, NATS or similar message transport.
  • Cross-platform systems thinking the agent also runs on Windows (WMI, Windows services, winreg, WinFSP).

Nice to have / bonus

  • Rust ObjC interop (objc2), or FFI experience generally.
  • Media-pipeline exposure GStreamer, AVFoundation, thumbnail / transcode workflows.
  • Secure secret storage and auth flows OAuth2, Stronghold / Keychain, Argon2.
  • XcodeGen or other project-generation / reproducible-build tooling.

Why Join R Systems?
  • Frequent Internal Hackathons: Engage in dynamic competitions with exciting prizes to keep your skills sharp.
  • Cultural Celebrations: Strengthen our familial bonds through shared celebrations, fostering a sense of community.
  • Diverse Project Exposure: Work on a variety of projects across sectors like Healthcare, Banking, e-commerce, and Retail, collaborating with leading global brands.
  • Centre of Excellence (COE): Benefit from technical guidance and upskilling opportunities provided by our team of technology experts, helping you navigate your career path.
  • E-Learning Platform: Gain access to comprehensive e-learning platforms coupled with a robust mentorship program to enhance your skills.
  • Open Door Policy: Embrace a culture of mutual support, respect, and open dialogue, promoting a collaborative work environment.
