Design Engineer — Frontend & Product Design

Valthos; United States; On-site; USD 90,000 - 130,000; Full time

Job summary

Valthos Inc. seeks a Design Engineer to own design and frontend implementation of core product experiences, from early user flows to production-ready interfaces.

You will work closely with users, founders, engineers, and computational biologists to translate complex workflows into clear, usable software. You will prototype concepts for research and discovery, shaping the visual language, design system, and architecture while ensuring rigorous data visualization and credible, user-centered

Qualifications

• Demonstrated experience owning both the design and frontend implementation of production-quality web applications, from early exploration through shipped product.
• Strong product and design judgment across interaction, information, and visual design, with the ability to create clear hierarchy, thoughtful flows, and polished interfaces for complex or information-dense software.
• Demonstrated ability to translate technical, ambiguous, or unfamiliar workflows into understandable software without removing the detail users need to make good decisions.
• Strong frontend engineering skills, especially with React, TypeScript, modern CSS, and component-based application architecture.
• Fluency moving between sketches, Figma, coded prototypes, and production implementation, with good judgment about the right level of fidelity for the problem.
• Systems thinking across design and engineering, with an emphasis on reusable interaction patterns, coherent product structure, maintainable components, and a consistent design language.
• Demonstrated ability to learn quickly, work independently, make reasonable tradeoffs, and carry an unclear problem through to a shipped solution.
• Strong communication skills, especially around design rationale, product tradeoffs, and implementation decisions.
• Comfort working on sensitive biological and national-security problems with discretion and good judgment

Responsibilities

• Own the design and frontend implementation of core product experiences, from early user flows and prototypes through production-ready interfaces.
• Work directly with users, founders, engineers, and computational biologists to understand complex operational and scientific workflows and translate them into clear, usable software.
• Design and build interfaces for data exploration, analytical workflows, alerts, review processes, and decision support, preserving the evidence and context users need to evaluate the result and determine what to do next.
• Rapidly prototype new product concepts for user research, pilots, demos, and customer discovery, and refine them through feedback and observations.
• Establish and evolve the visual language, interaction patterns, design system, and component foundations that keep the product coherent as it grows.
• Bring strong product judgment to decisions across information architecture, data visualization, interaction design, and frontend architecture.
• Improve the clarity, credibility, and usability of the product across onboarding, navigation, workflow execution, results interpretation, and review
