About the role

Design Engineers own the experience and visual language of Langdock, then turn that design into working software. You take an ambiguous product problem from the user's workflow through information architecture, interaction design, visual execution, and production code.

Responsibilities

  • Human-agent collaboration. Design how people give agents context, steer work in progress, approve actions, inspect tool calls, recover from failure, and review complex outputs.
  • Dense enterprise workflows. Make permissions, governance, configuration, evaluations, and workspace administration understandable to occasional users without slowing down experts.
  • Creating work with agents. Define the interfaces where people and agents produce and revise documents, analyses, spreadsheets, applications, and other structured work together.
  • The design system. Build and evolve reusable components, interaction patterns, typography, motion, and layout principles that keep a growing product coherent.
  • Prototypes and production interfaces. Turn uncertain ideas into realistic software quickly enough to expose difficult interaction and technical questions before the team commits to an approach. Then implement responsive, accessible product surfaces in React and Tailwind CSS, going into the backend when a strong end-to-end result requires it.
  • Product storytelling. Apply the same visual standard to launches, product pages, demos, and other materials that explain what Langdock does.

Qualifications

  • You have designed and shipped production interfaces in React, Next.js, and Tailwind CSS.
  • You use Figma when useful, but prefer testing important design decisions in working software.
  • You can take an ambiguous problem through user flows, information architecture, interaction design, visual execution, and production code.
  • You have enough full-stack familiarity to handle backend work when the experience requires it.
  • You understand complex business-to-business software, either through professional experience or strong related portfolio work.
  • You have a strong, considered point of view on visual design and can explain your decisions.
  • You care about interaction details, including transitions, hover states, loading behavior, responsiveness, accessibility, and empty states.
  • You give direct, constructive feedback and help other engineers improve the quality of their interfaces.
  • You care about the people around you and contribute to a thoughtful working environment.
