Staff Platform Engineer - Remote

About us

Felicity is a beautiful creation tool for browser automations.

Automating browser workflows is often a frustrating and time-consuming task for engineers and operators. At Felicity, our mission is to deliver a browser automation platform that combines elegant UI with blazing fast performance. We believe AI should enhance, not replace, structured systems. By layering AI with deterministic execution, Felicity delivers faster and more reliable outcomes than purely agentic tooling.

We’re currently focused on the healthcare vertical, a space where manual workflows, data entry, and repetitive tasks are especially prevalent. Founded in late 2024, Felicity is already the browser automation platform of choice for several healthcare companies.

We’ve raised $5.75M from top investors including Accel, XYZ, and Afore. You will join a small team of staff engineers from Square, Google, Oscar, Palantir, and Apple.

Tech

• A real-time no-code editor built into a Chrome extension, powered by WXT. Advanced synchronization technology using CRDTs that allows live updates and consistency across multiple tabs and browsers.

• Proprietary execution engine, inspired by Playwright, built for speed and bulk runs on your local Chrome.

• Browser Automation Language (BAL) - our DSL that abstracts away instructions from execution and encodes common web paradigms.

What you’ll do

• Scale and operate our fleet of virtual browsers to run thousands of automations concurrently.

• Improve our durable execution engine to increase reliability and support human-in-the-loop behavior.

• Increase observability across the stack to improve availability and latency.
