Product Designer

About Stainless

Stainless is a fast-growing tech startup building the future of APIs. Our customers include industry leaders like OpenAI, Anthropic, and Cloudflare. We have raised over $35 million from a16z, Sequoia, and founders/C-levels from Stripe, Datadog, Segment, Linear, and more. We are headquartered in NYC, just west of SoHo, and are a team of ~60 strong expecting to double in the next ~9 to 12 months.

About The Role

You'll shape the complete developer experience at Stainless — designing the product interfaces developers use to build with our API Platform and creating the brand identity and marketing presence that brings them to us. We're looking for a Product Designer generalist who gets excited about complex, technical products and can work across the full spectrum of design. Beyond individual contributions, you'll help establish Stainless's design culture and grow our design team. This is an in-person role based in New York City.

What you'll do

• Design work
• Design and integrate new products with the Stainless Platform
• Refine existing functionality and lead design on greenfield projects from inception to launch
• Evolve the Stainless website and marketing assets
• Create a polished, cohesive design language across product and brand
• Translate complex, ambiguous workflows into beautiful, intuitive interfaces
• Guide your designs into production through close collaboration with engineering

• Design culture & team
• Drive a culture of polish and user-centricity across the company
• Help develop our user research practice—conducting research and synthesizing insights into designs
• Contribute to hiring and shaping the design team as we grow

Who you are

• Core requirements:
• 5+ years of design experience as a designer
• Strong portfolio demonstrating work across both product and brand design
• Deep understanding of how developers think, with ability to design for technical audiences
• Strong collaborator who works well cross-functionally with engineers
• Comfortable conducting user research and translating findings into design decisions
• Able to reason about complex workflows and simplify them through design

• Nice to haves:
• Not afraid of frontend code—ideally able to implement many of your own designs
• Comfortable building interactive prototypes (HTML/CSS/JS)
• Experience designing developer-focused products
• Technical understanding of APIs, codegen, or similar infrastructure concepts
• You'll thrive here if you have deep respect for engineering constraints, enjoy working closely with technical teams, and want to help build something from the early stages.

Benefits

Paid team lunch/meals during workdays. Flexible PTO plus 3 weeks of company-wide vacation a year (2 weeks in December, 1 week at the end of the summer).
