About the role

Key responsibilities & impact

Work on the web application where we deliver results to scientists. Ship features end to end, owning the full stack from planning to launch.
Work with our bioinformaticians to turn complex pipelines into intuitive web application UIs.
Help set the engineering quality bar, practices and culture at Plasmidsaurus so our small team can ship even more.

Requirements

What you’ll need

You can pick a problem and solve it. We don’t expect you to be an expert in everything we use, but we expect strong frontend skills and web fundamentals, and a background working with parts of our stack (React, Flask, Postgres, AWS).
You have a bias towards action and you ship fast. You notice what's broken, propose the fix, and care whether users like what you shipped.
You have strong design and UX sensibility.
You ramp fast in new domains. No biology background is required, but you should lean into complexity rather than away from it.
You’ve taken products from 0 to 1 before. Perhaps you’ve been an early employee or founder at another startup like so many of our team – or built successful side projects.
You have experience with performant, data-heavy browser rendering (canvas, WebGL, visx).
You have background or interest in bioinformatics or life sciences.

Benefits

Comp & perks

Ownership and impact. Your work goes directly to 70,000 scientists, including Nobel laureates, who trust Plasmidsaurus with their research.
A tower office in South San Francisco with bay views, state-of-the-art lab, and the occasional batch of liquid nitrogen ice cream.
