Job description

We're looking for a Product Engineer who loves Windows and loves building products in a fast-paced, iterative environment.

Granola is an Electron app with deep OS integrations: system audio capture, accessibility APIs, webcam video streaming, and more. 

In this role, you will:

Own the development of new user-facing features end-to-end, making sure they work brilliantly on Windows

Own the Granola experience on Windows. You'll feel every papercut because you'll use it every day

Optimise the application for speed, scale, and reliability on Windows

Work across the stack, from our React/TypeScript UI to native OS integrations where needed

Interact with users to understand their problems and design solutions

Collaborate with a cross-functional team of engineers, product managers, designers, and other members of the team to make our Windows app as good as our macOS app (or better?!)

Your background looks something like:

Engineering experience at tech and product-driven companies

You use Windows as your main OS, and have done for several years

Proficiency with TypeScript, Node.js, and React

Experience building and maintaining desktop apps on Windows (Electron experience is a big plus!)

Comfortable navigating Windows-specific APIs and tooling when needed, even if you're not a low-level specialist

As a person, you…

Are first and foremost a builder

Are excited to work in-person from our office in London (most of the time)

Love working in a startup environment (you either have experience working in a startup or are really drawn to the zero-to-one phase)

Value working with people who are kind, ambitious, and pragmatic

Thrive in a fast-paced environment with evolving requirements and shifting priorities

About the opportunity

We are living in the most exciting time for tool builders since Engelbart's demo in 1968. We want to assemble the best crew to build this future together, here in London. Our compensation philosophy is to pay slightly above market on salary and above market on equity.

We do our best work in person, and so our team spends time together five days per week in our new, bright, and spacious office at Old Street. We are happy to offer relocation assistance to candidates who'll be moving to London to join us.
