Senior​/Product Designer

The Role

Planhat has spent a decade building an enterprise-grade platform for commercial teams. We integrate data, workflows, automation, AI, and collaboration into a single system that runs some of the most critical processes inside high-growth Fortune 500 companies. We're not in the business of building surface-level UI or feature-by-feature point solutions. We've built a horizontal platform made up of composable primitives, and expect the same in our design approach.

Despite our product's maturity, the product design function is a tight-knit, early stage team, so there's considerable opportunity for ownership and rapid growth in both scope and seniority. You'll work closely with our product team and creative studio to raise the bar for our product experience as we enter a period of unprecedented scale. You have a strong eye for aesthetics, and you're comfortable in code, going beyond mockups to get the HTML and CSS right in the codebase itself.

Not a full-time engineer, but hands-on enough to understand what you write, rather than just prompting for it. On a daily basis, you'll:

• Turn abstract capabilities — data, automations, AI, permissions — into clear, intuitive user journeys
• Design ambitious best-in-class interfaces by creating a scalable design system that redefines how enterprise software looks and feels
• Design pixel-perfect, information-dense interfaces that stay clear at scale

Product sense, aesthetic taste and craft are crucial. To succeed in this role:

• You'll have an aesthetically-driven opinion on how digital interfaces are evolving and where we should position ourselves at the leading edge
• You think in universal systems and flows, not individual interfaces or surfaces
• You are skilled at reducing interface complexity to guide users towards intended outcomes without oversimplifying
• You have strong UI craft, and care about how something feels, not just how it looks
• You're curious, opinionated, and want to own an entire roadmap, not just troubleshoot incoming tickets

Technically, you must be:

• comfortable working in the front-end—Vue templates and Tailwind CSS—and understand what you write rather than just prompting for it
• experienced with navigating a large codebase (ours is Vue, in a repo of 1M+ lines of Type Script): you read the code, ask the right questions, and don't break things
• fluent with and curious about staying hands-on with AI coding tools as the frontier moves—and inspiring others to level up their tools and techniques around you

Experience with enterprise or data-heavy products is a plus, but ability, judgment, and drive matter more than pedigree.

Strong competence in, and a strong willingness to learn:

• Design — Figma
• Code — Vue 3, Tailwind CSS, Type Script (read and navigate a large codebase)
• AI — Claude, Codex, or a comparable AI coding assistant in an IDE; skills, loops, etc. (desirable)

In a year, you're succeeding if:

• The product looks and feels dramatically elevated—sharper, clearer, and more consistent—and the parts you've crafted are notably stronger than those you haven't
• "How does this feel to use?" has an obvious, good answer—because of you
• Your design-system components get used across teams (design, product, engineering, creative) by default
• Engineering and product trust you
• The team ships exceptional interfaces faster because of you and the processes you've introduced

The Product team are the architects of Planhat's product direction and market position, making the right bets on where to build and executing on them with speed and quality. We sit at the intersection of engineering, design, and commercial, owning both the vision and the velocity. We think in systems, move fast, and combine deep technical and market understanding to build the platform that defines the next era of enterprise software.
