Senior Product Designer

About the Role

We're looking for a Senior Product Designer to lead complex design initiatives and play a critical role in shaping high-quality, customer-centered experiences across Karbon's product.

As a senior individual contributor, you'll operate with a high degree of autonomy, defining problems, exploring solutions, and delivering well-crafted designs end-to-end. You'll partner deeply with Product and Engineering, influence standards and quality beyond your own work, and help elevate the overall design practice through mentorship and example.

Key Responsibilities

• Own Experience end to end: Partner with Product and Engineering to define the problem space. Use LLMs to clarify intent, draft briefs, pressure-test assumptions, and surface edge cases and risks before committing to a direction.
• Prototype to set direction: Use AI-assisted tools to build and iterate on flows and lightweight interfaces quickly. Let AI accelerate the generation while you guide structure, behavior, and craft. Partner with engineers to decide what moves into the product.
• Validate with customers early: Talk directly with customers, run quick tests, and use what you learn to adjust direction. Treat research as a velocity tool, not a gate.
• Refine in Figma: Translate validated concepts into designs with complete state coverage, system alignment, and production readiness.
• Design for the platform: Move complexity under the hood so that experiences feel effortless for customers. Encode design judgement into decisions and principles that our people and tools can follow. Drive our craft forward with patterns, prompts, and an attention to detail that compounds over time.
• Mentor and support other designers: Be the mentor you wish you had for newer designers to learn from. Give timely feedback, collaboration, and best practices to follow.

What We're Looking For

• 6-8+ years of experience in product design, ideally within B2B SaaS or complex product environments
• Strong portfolio demonstrating end-to-end design thinking, interaction design, visual craft, and problem-solving across complex systems
• Proven ability to work autonomously on ambiguous problems and drive work forward with clarity and ownership
• Active use of LLMs in your design workflow, for problem framing, research synthesis, prototyping, or iteration, not just awareness of them
• Comfort using AI-assisted development tools to build and iterate on concepts, even without writing production code
• Excellent collaboration and communication skills, with experience partnering closely with Product and Engineering
• Comfort balancing strategic thinking with hands-on execution
• Experience contributing to or working within established design systems
• Passion for high-quality, customer-centered design and continuous improvement

Bonus:

• Experience designing for vertical SaaS, professional services, or accounting-adjacent products
• Experience designing AI-enabled product experiences

Why Work at Karbon?

• Gain global experience across USA, New Zealand, UK, and Canada
• 4 weeks annual leave plus 5 extra "Karbon Days" off a year
• Flexible working environment
• Work with (and learn from) an experienced, high-performing team
• Be part of a fast-growing comp
