Frontend Software Engineer

At Ark, we are building a transformative simulation platform for biomanufacturing—one that reimagines how new drugs and biological innovations are developed and produced. Our team of world-class experts in bioprocessing, simulation, and automation is crafting the first platform capable of modeling and optimizing the production of modern biologicals with unparalleled precision.

At the heart of Ark is the “virtual bioreactor”—a tool that shatters the constraints of the wet lab, empowering scientists and engineers to experiment in silico at unprecedented speed and scale. By replacing years of costly trial-and-error with limitless virtual experiments, our platform doesn’t just save time and money—it transforms the way breakthroughs happen. With Ark, a healthier, longer-lived future isn’t just possible—it’s inevitable.

We are looking for a Frontend Software Engineer to help us take this vision to the next level. You won’t just build software; you’ll design tools that inspire. The ideal candidate is driven by a relentless desire to create interfaces that are as intuitive as they are powerful—tools that don’t just work but delight, empowering scientists to move seamlessly from experiments to insights. You care deeply about accessibility and design, and you hold yourself to an extraordinary standard of excellence, knowing that every detail matters when building something truly transformative.

This is your chance to build something bigger than yourself—to create a product that changes lives.

As part of our team, you’ll own the future of frontend development at Ark, while contributing to full-stack features. You’ll work alongside a group of equally passionate individuals who manage their own infrastructure, developer experience, and release processes. Together, we’re building software from the ground up—software that changes the world.
