Sr Product Designer

Join to apply for the Sr Product Designer role at Pirros

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!

• Backed by top-tier investors and angels (YC, Funders Club, Plan Grid, Elephant)
• PROFITABLE, ~5M+ ARR and growing revenue at +10% month-over-month
• Competitive Package: salary, stock options, unlimited PTO, health benefits
• Co‑founders both come from structural Engineering, with industry experience
• 275+ firms using us today, growing 10% MoM, 120% NRR - customers include some of the top AEC design firms in the country
• Join a high‑trust, high‑autonomy culture with experienced builders and operators
• Tangible Impact! We’re solving real problems for the people who design the world around us while building the software stack of the future for architects and engineers

We’re hiring a Senior Product Designer to be a core partner to Product and Engineering as we design the next generation of Pirros. We’re looking for someone who enjoys starting from messy workflows, constraints, data, and working through them with the team to design systems that make sense. Must be comfortable constantly prototyping, testing, and iterating rather than waiting for a “perfect” solution.

• Product and Design work very closely from discovery through delivery, and designers are part of shaping what we build, not just how it looks.
• Engineers are collaborative and expect design to be in the room for scope, architecture tradeoffs, and sequencing discussions.
• We care about building 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.

• 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.
• Use constant prototyping (low‑fi wireframes, interactive prototypes, quick iterations) to explore options, validate assumptions with users and internal stakeholders, and de‑risk decisions before engineering commits.
• 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.

• 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.

• 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.

• 5–8+ years of product design experience, preferably in B2B SaaS with complex workflows (e.g., vertical SaaS, data‑heavy tools, internal platforms).
• Experience working in or adjacent to AEC, construction tech, or other…
