Product Designer

Job Overview: Sustainment is building the AI-native procurement platform for American manufacturing. We are looking for a Product Designer who can own meaningful slices of our end-to-end RFQ-to-PO experience. You will work as an equal partner with product and engineering to identify problems worth solving, explore solutions quickly, and ship high-quality workflow improvements. This role is a fit if you are excited by messy, real-world domains and want to grow into deeper product leadership over time.

What you will do:

• Own design for key workflows in the procurement lifecycle: RFQ creation, quote review and comparison, award decisions, purchase order creation, and delivery/exception handling.
• Partner with PM, other designers, and engineers from discovery through delivery. You will help frame problems, test approaches, and make tradeoffs that balance user value, business impact, and technical feasibility.
• Plan and run lightweight user research. Talk to current manufacturers and suppliers, validate assumptions with rapid prototypes, and iterate based on evidence.
• Produce clear UX artifacts in Figma: journey maps, wireframes, interactive prototypes, and high-fidelity designs aligned with our design system.
• Collaborate tightly with engineering to ensure high-quality implementation. You will create specs that enable smooth handoffs and be involved through QA and launch.
• Contribute to our emerging design system and reusable workflow patterns so we can move faster without sacrificing coherence.

In your first 6-12 months, you will:

• Ship multiple improvements to core workflows that materially reduce user friction.
• Establish trusted working rhythms with PM and engineering partners.
• Partner with other designers to improve the overall design process at Sustinament.
• Demonstrate strong rationale in decision making grounded in user insight and product goals.
• Help evolve consistent patterns for data-dense procurement screens.
• Test design prototypes and concepts with users and potential users.
• Present your designs and the rationale behind them to the team, leadership and stakeholders.
• Be at the forefront of designing AI native experiences based on quickly evolving best practices.

If you see yourself in this description and the work sounds diverse and interesting, we can't wait to talk to you. We are extremely excited about the opportunity that lies before us at Sustainment and we're looking for more great people to help us make the most of it.

Your areas of expertise:

• 3+ years of product design experience on complex web applications or SaaS products.
• Strong portfolio demonstrating end-to-end workflow thinking, not just single screens.
• Proficiency in Figma and modern prototyping practices.
• Comfort working in ambiguity and moving from rough problem framing to shipped solutions. Startup experience isn't required but is a plus.
• Solid collaboration and communication skills, especially with engineers.
• Bonus: experience in enterprise, operations, supply chain, manufacturing, Figma Make, or AI-assisted UX.
