We are scaling fast.

Our vision

bring price transparency, automation, and intelligence into one of the most manual, underserved verticals in the economy. We're inspired by clean design and modern architecture—and we're pushing forward with AI-native product thinking, not bolting it on later.

The Role

We're hiring a Head of Product Design (UI / UX) who is obsessed with creating intuitive, elegant, and impactful user experiences.

You've shipped something before—whether at a startup that scaled, a product that users loved, or a platform that redefined a workflow.

You know the pain of turning complex problems into simple, usable solutions, and you want another shot at shaping an industry from 0 ? 1. At Downstream, you'll work directly with our CEO, CTO, and Product team to :

• Define and own the design vision for our marketplace, supplier tools, and customer experience.
• Lead end-to-end design for web and mobile, including UX flows, UI systems, and visual identity.
• Architect AI-native product experiences that feel intuitive, not artificial—helping users trust automation and agents in critical workflows.
• Collaborate with engineers and product managers to ship fast: prototype, test, iterate, and refine.
• Build and scale our design system so we can move quickly without sacrificing quality.

Responsibilities

Drive the product design strategy across customer, supplier, and internal platforms.

Build and maintain UI / UX standards that reflect simplicity, trust, and efficiency.

Design AI-native experiences—where agentic systems interact seamlessly with users, data, and decisions.

Mentor and grow a design team as we scale.

What We're Looking For

Battle-tested designer : You've shipped real products (startup, marketplace, SaaS, or similar).

AI-forward mindset : You don't just add AI—you design around it, making it feel natural and empowering.

Builder's DNA : Comfortable with ambiguity, speed, and iteration.

You've felt the pain of building in the real world and still want more.

Understanding of modern frontend frameworks (bonus : Flutter, React)

Experience in marketplaces, logistics, SaaS, or fintech.

Familiarity with B2B workflows and procurement tools.

Contributions to open-source design systems or AI products.
