About the role

IMPORTANT: the best way to apply is by submitting a video application by following the instructions on our jobs page here.

At Tasklet, we’re building the cloud agent OS for work. Our product needs to run everywhere — web, desktop (Mac & Windows), iOS, and Android — so our users can work with their agent wherever they are. We believe we can be the main app that most knowledge workers use for everything.

We’re looking for a staff-level engineer to own our client application stack. You’ll be the person who makes Tasklet feel fast, native, and rock-solid on every platform. This is a foundational leadership role with very generous equity — we need someone truly world-class.

Compensation

  • $280k → $380k salary
  • 0.4% → 0.80% equity
  • Competitive benefits (medical, dental, vision, 401k, 4 weeks PTO, free lunch, etc)

Responsibilities

  • Own the client application layer across web, desktop, iOS, and Android
  • Build and maintain our real-time sync and API architecture so the agent experience is seamless
  • Define our cross-platform strategy: what’s shared, what’s native, and where to invest
  • Make Tasklet feel native on every platform — fast startup, smooth interactions, platform-appropriate UX
  • Drive performance relentlessly — our users live in this app all day, every millisecond matters

Our ideal candidate

  • Very strong CS fundamentals & experience building complex distributed systems
  • Exceptional, AI-native programming skills using an ultra-modern stack
  • You’re AGI-pilled & deep into relevant AI tech
  • You’ve built and shipped production client apps across multiple platforms
  • You obsess over performance, startup time, and the small details that make an app feel great
  • You’ve built real-time data systems, sync engines, or complex state management at scale
  • You could easily be a staff engineer at a top AI lab — but you want the outsized impact of a startup, and you believe Tasklet can win

About Tasklet

Tasklet is building the cloud agent OS for knowledge work. Instead of switching between dozens of SaaS apps, our users connect one AI agent to all their tools and let it handle their work — pulling data, taking actions, generating UIs on the fly, and running 24/7 in the cloud.

We've raised $29.5M from Union Square Ventures, Lightspeed, Y Combinator, Jeff Dean, and Patrick & John Collison. Our team of 9 in San Francisco is led by Andrew Lee (founded Firebase, sold to Google) and Jonny Dimond, and includes engineers from Google, Amazon, and OpenAI.

We're growing fast, shipping constantly, and competing directly with the AI labs to build the agent platform that replaces legacy application software. Nearly every line of code here is written with AI — we're an engineer-driven team that believes deeply in giving models more agency and using them to multiply what a small team can do.
