Senior Product Designer

About Parspec

Parspec is building the AI and digital infrastructure for the construction materials supply chain.

Construction is a $15 trillion industry, yet the systems that underpin the buying and selling of materials remain fragmented, manual, and disconnected. Distributors and rep agencies rely on spreadsheets, PDFs, phone calls, and siloed tools to find new products and quote and manage projects, creating delays, errors, and margin erosion across the supply chain.

Parspec is an AI-native platform that powers how construction products are discovered, bought, and sold. Trusted by more than 300 MEP distributors and rep agencies, Parspec helps project-driven businesses bid faster, win more work, and operate more profitably. By combining product intelligence, AI-powered workflows, and a connected ecosystem, Parspec is laying the foundation for a more intelligent, efficient construction supply chain.

Founded in 2021 and headquartered in San Mateo, California, Parspec has raised $31 million from leading deep-tech and construction-technology investors.

The Opportunity

What does it take for a distributor to hand a full bill of materials, a customer quote, or an inbound order to an AI agent, and trust what comes back? That is one of the central design challenges you’ll help solve

Our users are quoters and project managers at distributors and manufacturer rep agencies who run their businesses in Parspec. The workflows you design span a range: some are human-driven, some are AI-assisted, and increasingly some are agent-led. AI already ingests spec sheets and PDFs, helps select and match products, and powers search. Agents are the next step, taking on whole tasks such as building a quote or processing an inbound order while people review, correct, and approve the result. As our Senior / Staff Product Designer, you will design across that whole range and help define how workflows move along it: where the agent acts on its own, where a human stays in the loop, and how users verify the agent's output at a glance.

You will sit with customers, prototype agent workflows, test them with real users, and ship them with engineering. Parspec is live in the market with AI doing real work for real customers, so the trust and usability bar you set shapes what customers experience every day.

We are an AI-first product and engineering team. Our product and design team uses AI to prototype, iterate, and collaborate with Engineering, and we keep refining how we work.

You'll report to the VP of Product. Each product surface has a PM–designer pair that co-owns work from discovery through delivery, across a product team in the Bay Area and Bangalore.

This is a hybrid role. Candidates must be able to work from our San Mateo office 2–3 days per week.

What You Will Achieve and Key Responsibilities

End-To-End Feature Design Ownership

• Own the design of product features from early discovery and concept development through detailed design and delivery with engineering.

• Work closely with Product and Engineering, compressing iteration cycles from concept to production-ready spec.

• Translate complex workflows into intuitive interfaces and clear user flows.

• Design how agents and people share work: how users verify AI output, handle uncertainty and exceptions, recover from errors, and review consequential actions before they take effect.

Design Excellence

• Prototype fast to stress-test edge cases and explore interaction patterns at a pace aligned with our engineering cadence.

• Produce high-quality interaction and visual design with strong attention to hierarchy, clarity, and usability.

• Communicate design decisions clearly through prototypes, documentation, and rationale.

• Maintain a high bar for usability, accessibility, and visual polish across the product.

Design System & AI Prototyping

• Contribute to and evolve our design system by developing reusable patterns and components in Figma that scale across our product surfaces (e.g., distributor portals, manufacturer tools) and responsive interfaces.

• Shape and evolve our AI prototyping workflow, keeping it in sync with the design system and engineering's code-generation pipeline so components stay structured and token-ready.

User-Centered Product Design & Strategy

• Go to the source: run research and usability testing directly with distributors and reps, and reduce cognitive load in data-heavy workflows.

• Partner with Product, Customer Success, and Sales to measure product usage and turn what you learn into design improvements.

Why This Matters

Construction runs on complex workflows and has been slow to adopt new technology. In this market, design is one of the main differentiators and the main enabler of AI adoption: AI only gets used if people understand what it did, can check it quickly, and trust it with real work. That makes design central to what Parspec builds, not a layer on top. Our designers shape the roadmap and product vision alongside Product and Engineering. As a Senior or Staff Product Designer, you will help decide how AI shows up in our customers' daily work and what we build next.

Who You Are

This role is a great fit if you:

• Love breaking down complexity. You take dense, multi-step B2B workflows and make them simple without dumbing them down.

• Are obsessed with customer problems. You go to the source, watch people work, understand their problems, and ground design decisions in user problems.

• Validate with prototypes, not screens. Our product managers and designers prove out features by building working prototypes and putting them in customers’ hands, not static mockups.

• Like playing a hybrid role. On selected projects, you'll own both product framing and design: defining the problem, shaping scope, and partnering with engineering through delivery.

• Thrive on agility and adaptability. We're a lean team that ships fast and continually adapts how we work.

We value both career product designers and hybrid profiles, including product managers who moved into design and have practiced it as their primary role for a meaningful stretch.

Qualifications

Minimum Qualifications

• 5+ years of experience in product design or UI/UX design, with a focus on enterprise SaaS products and complex workflows.

• Demonstrated use of AI-assisted tools in your design workflow. This is not a future aspiration; we expect active, practical fluency. Our team works with a variety of AI tooling for design prototyping, validation, and handoff to Engineering.

• Strong Figma skills (design systems, auto-layout), paired with code-adjacent prototyping.

• A portfolio demonstrating strong product design for complex web applications, data-dense interfaces, and enterprise workflows.

• Proficiency in user-centered design methodologies, designing with systems, accessibility standards, and usability testing.

• Strong communication, collaboration, and stakeholder management skills.

Preferred Qualifications

• Shipped customer-facing AI experiences, such as agent workflows or human review of AI output.

• Experience with bidirectional design-to-code workflows (e.g., Figma ↔ Claude, design token pipelines, or AI-assisted front-end generation).

• Expertise in designing for B2B applications, particularly in procurement, construction tech, or marketplace platforms.

• Familiarity with front-end development concepts (HTML, CSS) and modern design systems (e.g. React-based frameworks).

We are considering candidates at the Senior or Staff level, based on experience. At Senior, you own complex workflows end to end. At Staff, you also shape direction across product surfaces, establish shared interaction patterns, and raise the team's design quality.

What We Offer

• The base salary range for this role is $150,000 - $190,000, plus bonus and equity options. Final compensation depends on level, experience, and skills

• Unlimited PTO policy

• Medical, dental, and vision coverage

• Flexible hybrid work environment

• Regular team offsites and a budget for professional development
