About the role

Staff Product Designer role focused on simplifying complex, data-heavy workflows in MarianaOS, growing and owning the design system, and collaborating cross-functionally to deliver intuitive, fast, and human-centered software for a mining-focused organization.

Responsibilities

  • Take complex, data-dense workflows in MarianaOS and design clear, usable information architecture and flows ensuring MarianaOS is easy and fast to use for the 100s of employees here that rely on MarianaOS daily to do their complex jobs.
  • Grow and own our design system, including coded components and not just Figma files, which allows our engineers to quickly build great user interfaces with agentic tools.
  • Partner with PMs and engineers from early problem framing through shipped UI; you'll be in the room for the messy part, not just handed a spec.
  • Give and receive fast, direct design feedback across the team to help raise the visual bar and deliver valuable and usable products for end users.
  • Prototype directly in code when that's the fastest way to a real answer; pairing and working live with engineers rather than only handing off finished mocks so that great designs are delivered quickly.
  • Set short-horizon design direction (weeks to a couple months, not multi-year vision decks) so a fast-shipping engineering team stays pointed at something coherent.
  • Run and synthesize lightweight user research and feedback loops with customers and internal stakeholders, ensuring the products we are launching are grounded in user needs and feedback
  • Define best design practices/ways of working setting the tone of how design will function in the company as we grow.
