Senior / Staff Full Stack Software Engineer

Highlight — San Francisco, CA (On-site, 5 days/week)

Salary: $200,000 – $300,000 base, plus competitive equity

About the Role

We're hiring 3–5 Senior/Staff Full Stack Engineers to help build the core product from the ground up. This is genuinely full-stack work: Electron and TypeScript on the frontend, native system-level code in C++ and Swift, and deep integration with LLMs. Every engineer here shapes the product roadmap — you won't just be writing code, you'll be thinking about user research, product strategy, and the future of AI-human interaction.

What You'll Build

Core Electron app — design, build, and maintain cross-platform desktop features
End-to-end features — from UI through native modules, spanning both user-facing and infrastructure work
LLM integration — develop and integrate AI-powered functionality
Native code — system-level work in C++ (Windows) and Swift (macOS)
Architecture — help shape technical decisions and company direction

Requirements

5–10 years of experience as a Senior or Staff full-stack engineer (backend-leaning)
Track record of owning features end-to-end at a high-growth startup or top tech company
Experience building AI/LLM-powered features
Background in consumer productivity software
Willingness and ability to work on-site in San Francisco, 5 days a week

What Sets You Apart

A technical "spike" — a deep area of passion you've gone 10 layers deep on
Strong hands-on experience with TypeScript, Node.js, React, and Electron
Founder or early-stage startup experience
