Senior Product Designer chez Mach9

The role:

At Mach9, Product Designers craft the core experience that brings the power of AI and geospatial data to civil engineers around the world. You’ll work closely with engineering, product, and customers to translate deeply technical problems into clear, intuitive tools that accelerate infrastructure design.

This role is ideal for designers with experience designing for complex systems and technical users, working across the design stack, and the flexibility to move quickly when it matters.

You’ll design for a modern 2D/3D web-based environment that blends CAD-like precision with the usability of modern consumer tools, striking the right balance between rigorous design process and rapid product iteration.

Where you will make an impact:

• Lead design for core product workflows, from 3D feature extraction to quality assurance and geospatial review

• Collaborate closely with engineers to refine prototypes into polished, high-performance user interfaces

• Own the evolution of our design system and visual language, ensuring consistency across a growing product surface area

• Navigate technical constraints and real-world edge cases without sacrificing user experience

• Balance multiple priorities across customer needs, technical feasibility, and speed to value

• Drive both long-term UX vision and fast-moving delivery in a startup environment

What you bring:

• 4+ years of product design experience, ideally in technical, data-heavy, or 3D product environments

• Experience working on complex products with constraints related to spatial data, design precision, or engineering-driven interfaces

• Strong visual design, interaction design, and systems thinking skills

• Fluency in Figma and comfort working with and evolving robust design systems

• Demonstrated ability to work hand-in-hand with engineers to ship high-quality, thoughtful interfaces

• Comfortable moving between deep design exploration and pragmatic, iterative delivery

Bonus experience:

• Prior work with CAD, BIM, 3D modeling tools, or geospatial interfaces

• Familiarity with frontend technologies (e.g., React, Three.js, TailwindCSS)

• Experience conducting or synthesizing user research with highly specialized users

• An eye for visual clarity and information hierarchy in high-density UIs
