Staff Product Designer

About the role

Why join us? We're hiring a Staff Product Designer to own design at Siro end to end. This is a hands-on senior IC role where you'll partner with our Product, Engineering, and GTM leaders to reinvent how thousands of in-person sales teams work.

Responsibilities

• Own the product craft and quality— consistency, polish, and delight.
• Build the design system, patterns, and principles that scale as we grow.
• Design the mobile and web app surfaces and AI interactions.
• Go from idea to working prototype in hours with AI tooling, and pull the team into that loop.
• Plan and execute user research, including in-person customer visits and ride-alongs.
• Represent the voice of the customer in internal debates.
• Partner with senior leadership and our founder/CEO to frame problems, influence the roadmap, and set product direction.
• Raise the taste of the PMs and engineers making design decisions without you.

Requirements

• 8+ years designing product with quantifiable success.
• Exceptional interaction and visual craft. You can say why something feels off and what would fix it without hiding behind vibes.
• AI-native. You prototype with modern AI tools daily and are fluent enough with code to make things real.
• A systems thinker who still sweats the 4px decision.
• Customer-obsessed. You'd take a day in the field over a day in a planning doc, and you make it happen without being asked.
• Credible with senior leaders. You influence strategy on the strength of your reasoning and research, and you challenge a founder or an engineering lead without turning design into theater.
• Comfortable owning the whole surface. You decide where consistency matters and where to move fast, and you're at peace with the tradeoffs that requires.
• Energized by ambiguity, tough problems, and high expectations.

Why Siro

• You'll define what Design means at Siro — the standard, the systems, and scope of influence.
• Define the product language for a category still being invented. In-person sales is the biggest slice of selling and the most underserved by software.
• Work on a genuinely hard problem: messy spoken conversation, fragmented business systems, field execution, and AI agents in one product.
• Build for users who love it. Reps rely on it, sales leaders evangelize it, and you'll hear their gratitude in person.
• Operate on a small, senior team at a high-growth Series B company with real product-market fit and direct access to the Founder CEO.
