Senior Software Engineer II developing reliability and self - healing systems for operational excellence at Samsara. Contributing to AI - driven tooling and mentoring teams through best practices in engineering.
About the role
- Senior Desktop Software Developer leading a greenfield rewrite of Sync.com desktop application with a modern Rust-based architecture. Focus on technical ownership and high-quality software delivery.
Responsibilities
- 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.
- Tackle the genuinely hard problems end to end: sync engine internals, deep OS file-system integration, and robust update/release infrastructure—all of which we consider equally critical.
- Design and operate a secure auto-updater: signed delivery, signature verification, staged rollouts, rollback, and reliable cross-platform update mechanics.
- Define the quality bar for the new codebase from scratch—test strategy, automated coverage, CI/CD, observability, and crash reporting—and hold the product to it.
- Manage platform-specific concerns including code signing, notarization, packaging, background services, and native shell/file-system integrations.
- Integrate our existing end-to-end encryption layer into the client, ensuring cryptographic operations are correct, performant, and used safely.
- Use AI-assisted and agentic development tools (Claude Code, Codex, and similar) to accelerate delivery, and help establish best practices for AI-augmented workflows across the team.
- Collaborate with product, security, and backend teams to ship features that scale.
Requirements
- 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.
- Experience leading or anchoring a significant rewrite or greenfield build—you’ve made the foundational architectural calls and lived with the consequences.
- 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; working understanding of E2EE concepts (AES-GCM, key management, client-side encryption).
- Comfort and fluency with AI coding tools and agentic workflows—you actively use them and understand their strengths and limits.
- Ownership mindset: you treat the desktop product as yours and drive it from architecture to shipped, supported software.
Benefits
- Comprehensive health benefits
- Flexible remote work
- Opportunity to lead the technical direction of a flagship desktop product
- High-impact work on a platform trusted by millions of users
- A profitable, privately held company investing in long-term product innovation
