About the role

  • Work directly with founders, engineers, and computational biologists to translate ambiguous operational, scientific, and defense-related workflows into clear and usable software.
  • Rapidly prototype new product concepts for users, pilots, demos, and customer discovery.
  • Improve the clarity, credibility, and usability of the product across onboarding, navigation, dashboards, workflow execution, and results interpretation.

Responsibilities

  • Own the design and frontend implementation of core product experiences, from early user flows and prototypes through production-ready interfaces.
  • Systems thinking across both design and engineering: you care about reusable patterns, maintainable components, and coherent product structure.
  • High autonomy: willingness to take a problem and build an end-to-end solution.

Requirements

  • Experience working closely with product and engineering teams in fast-moving environments.
  • Experience designing and building production-quality web applications.
  • Strong UX and visual design judgment, with the ability to create clear flows, polished interfaces, and usable interaction patterns.
  • Ability to work in Figma or similar design tools, while also being comfortable implementing your own designs.
  • Ability to operate independently, make reasonable tradeoffs, and ship without waiting for perfect specifications.
  • Strong communication skills, especially around design rationale, product tradeoffs, and implementation decisions.
  • Willingness to work on sensitive, defense-adjacent, and bio-related products with seriousness and discretion.
  • Strong product taste and the ability to simplify complex workflows without oversimplifying the underlying domain.
  • A bias towards action. You can move from rough idea to working prototype to production implementation quickly.
  • Comfort with ambiguity, especially in an early-stage company where product direction, customer needs, and technical constraints are still evolving.
  • Respect for users operating in serious, mission-driven environments where clarity, reliability, and trust matter.

Skills

  • Strong frontend engineering skills, especially with React, TypeScript, modern CSS, and component-based architecture.
