Ark provides high-fidelity simulation software designed to accelerate time to market and increase throughput in bioprocessing. Their platform allows scientists to design, optimize, and scale bioprocesses faster by enabling thousands of experiments to be run in parallel *in silico*, thus shortening timelines and reducing the need for physical experiments. The software enhances decision-making from early-stage process development to commercial manufacturing by optimizing critical process parameters and improving titer and overall process robustness. Ark's solution is bioreactor agnostic, works with sparse data, and is designed by scientists for scientists with an intuitive, no-code interface. The company emphasizes data security, being SOC 2 Type II certified, with data encrypted at rest and in transit, hosted in a secure single-tenant AWS environment with strict permission and usage controls.

Ark is building the world’s highest-fidelity bioprocess simulation software to help life-saving therapies reach patients faster. By democratizing complex AI and multi-physics models in an intuitive software interface, we are ushering in a new era of digital bioprocessing.
With Ark, scientists can replace weeks-long, costly ($10K–$1M+) bioreactor experiments with simulations that run in seconds. This enables researchers to explore thousands more scenarios, accelerate time to market, and ensure more medical breakthroughs make it from the lab to the world.
We are looking for a UI-focused UX/UI Designer to lead the visual design of our customer-facing scientific software. This role is ideal for a designer who thrives in deep technical domains, enjoys strong ownership and autonomy, and is energized by working directly with scientists and software engineers to bring transformative medicines to patients faster.
About the Role
As Ark’s sole designer, you will shape the look, feel, and interaction patterns of our core product. You’ll work directly with the CEO, scientists, and software engineers to translate complex scientific workflows into intuitive interfaces. The focus is predominantly UI design, with a strong emphasis on clarity, usability, and visual communication for data-heavy applications.
You’ll own and evolve our existing design system and partner with engineering to ensure high-quality implementation.
