About the role

We're rebuilding our desktop application from the ground up.
Our current clients are built on native, platform-specific stacks (C++/Swift and friends), and we're consolidating onto a unified, modern Rust-based architecture across macOS, Linux, and Windows-treated as first-class, equal targets.
We're looking for a Senior Desktop Software Developer to be the technical owner of this greenfield rewrite.

Lead a greenfield rewrite of our desktop client, migrating from native platform-specific code to a unified Rust-based architecture.
Own the complete desktop SDLC-architecture, implementation, release engineering, and ongoing maintenance-across macOS, Linux, and Windows as equal priorities.
you treat the desktop product as yours and drive it from architecture to shipped, supported software.
This is a high-ownership individual contributor role: you'll architect the new application, define how we build and ship it, and set the engineering quality bar from day one.
Design and operate a secure auto-updater: signed delivery, signature verification, staged rollouts, rollback, and reliable cross-platform update mechanics.
Manage platform-specific concerns including code signing, notarization, packaging, background services, and native shell/file-system integrations.
Collaborate with product, security, and backend teams to ship features that scale.
Experience leading or anchoring a significant rewrite or greenfield build-you've made the foundational architectural calls and lived with the consequences.
Ownership mindset: you treat the desktop product as yours and drive it from architecture to shipped, supported software.
Opportunity to lead the technical direction of a flagship desktop product

Significant depth in desktop application development, with a track record of shipping and maintaining production software across macOS, Linux, and Windows.
Strong proficiency in Rust, including async patterns, FFI, and performance optimization.
Hands-on experience with cross-platform desktop frameworks such as Tauri and/or Electron.
Direct experience designing or operating auto-update systems, including secure distribution and code signing/notarization.
Ability to define a testing and quality strategy from a blank slate, not just work within an existing one.
Comfort integrating existing cryptographic libraries correctly
Comfort and fluency with AI coding tools and agentic workflows-you actively use them and understand their strengths and limits.

Experience with cloud storage, file sync, or backup products.
Familiarity with native APIs such as macOS File Provider, Windows Cloud Files API, or Linux FUSE.
Background migrating off native C++/Swift codebases toward Rust.
Experience contributing to or maintaining open-source Rust projects.
Work on privacy-first software that genuinely protects users.
High autonomy and real architectural influence.
A team that embraces modern, AI-augmented engineering.
