Othello is building at the frontier of real-time generative AI, helping sales teams make better high-stakes decisions in the moments that matter most, while a customer conversation is still happening. Our platform is used by leading sales organizations, including Fortune 500 companies, to deliver live intelligence before, during, and after meetings. We’re an early-stage startup that moves extremely fast, gives people real ownership, and is built for people who want to solve hard technical problems at the edge of what’s possible.

This is not a standard frontend role. We are looking for someone who understands desktop operating systems at a real systems level and knows how to build software that feels native, responsive, and production-grade. The core of the role is owning the desktop layer itself: windowing, process architecture, system behavior, permissions, performance, OS integrations, and native modules.

Experience with React and Electron is a strong advantage, but the priority is deep desktop and OS-level engineering strength. Bonus points if you also have strong UI taste and can help craft polished product experiences on top of the systems work.

What you’ll do

Build and improve a high-performance desktop application across macOS and Windows

Own OS-level behavior including window management, lifecycle, background processes, system events, permissions, notifications, installers, updates, and device or app integrations

Design and implement native modules and system-level integrations where needed

Work across Electron, native code, and desktop architecture to push the product far beyond a typical web app in a shell

Help define how the application is structured across processes, IPC boundaries, native capabilities, and the frontend layer

Drive performance, responsiveness, stability, and correctness across the desktop stack

Contribute to product experience and interaction quality, especially where desktop behavior directly shapes UX

What we’re looking for

Strong Senior desktop software engineer

Deep macOS experience - MUST

Windows experience highly valuable

Electron experience - MUST

Experience with native development in Swift, Objective-C, C++, Rust, C#, Win32, or similar

Native modules and OS integrations important

Performance, memory, CPU, permissions, and background services experience important

Product-minded, with strong attention to UX quality

Not a traditional systems admin / IT profile
