Staff - Principal Product Designer

Pirros is reshaping and revolutionizing how Architecture and Engineering firms manage design details. Our software empowers AECO design professionals (Architects, Engineers, Contractors, and Owners) to streamline their detail management process more effectively, reduce errors, and speed up project delivery. We’re building the system of record for detail management in a $12T+ industry that’s been underserved by technology for too long!

What You’ll Own:

• Workflow & UX Design

  • Build an AI-first, workflow-deep product, not just features — and design is central to making that usable.

  • Partner with Product to map end-to-end workflows across QA/QC, project operations, and collaboration.

  • Translate these workflows into flows, information architectures, and interaction patterns that can support deep, repeatable use over time.

  • Own the UX for core product areas from early concept → detailed design → support during implementation.

• Product Collaboration

  • Collaborate closely with PMs during problem framing, concept exploration, and refinement of user journeys.

  • Take initial ideas and discovery outputs and turn them into robust UX and UI that can actually ship.

  • Work hand-in-hand with engineering to scope designs realistically, iterate with technical constraints, and maintain product quality through delivery.

  • Help refine and maintain design guidelines, patterns, and components, so the product feels cohesive as it grows.

• Research & Customer Understanding

  • Join customer calls, discovery sessions, and workflow deep dives to understand how AEC firms actually work today.

  • Turn customer feedback and observation into design hypotheses, prototypes, and experiments.

  • Help articulate tradeoffs: what we simplify, what we automate, what we expose, and what we intentionally leave out.

• Complex UX & Data

  • Design interfaces that work with messy, structured + unstructured data (rules, model metadata, RFIs, issues, histories) without overwhelming users.

  • Think in systems: how a change in one part of the product (e.g., QA/QC rules) affects other areas (e.g., projects, reporting, collaboration).

  • Partner with Product and Engineering to explore how AI-powered features (summaries, suggestions, natural-language rule creation) can be woven into everyday workflows in a way that feels helpful, not gimmicky.

Who You Are:

• A Senior Product Designer to be a core partner to Product and Engineering as we design the next generation of Pirros.

• Experience in:

  • B2B SaaS with complex workflows (e.g., vertical SaaS, data-heavy tools, internal platforms).

  • AEC, BIM, construction tech, industrial, or other deeply operational domains.

  • Designing data-heavy products (analytics, rules engines, workflow tools, admin consoles).

  • Familiarity with AI/LLM-powered UX patterns (summarization, suggestion, natural language input) and how to integrate them without overwhelming users.

  • Strong interaction design and UX systems thinking. Comfortable designing not just screens, but the logic, states, and flows behind them.

  • Designing multi-step, multi-persona workflows where information moves between different roles and tools.

  • An early-stage startup where you’ve had to balance speed, quality, and incomplete information.

• Comfortable constantly prototyping, testing, and iterating rather than waiting for a “perfect” solution.

• Enjoy starting from messy workflows, constraints, data, and working through them with the team to design systems that make sense.
