Senior Product Designer

Who We Are

Lightning AI is the company behind PyTorch Lightning. Founded in 2019, we build an end-to-end platform for developing, training, and deploying AI systems—designed to take ideas from research to production with less friction.

Through our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer-first software with cost-efficient, large-scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.

We serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.

The Way We Work

The people who thrive here are builders who move fast, communicate openly, take ownership, and continuously improve themselves, their teams, and our company. Here's what that looks like in practice:

Move with Urgency: We move quickly, make thoughtful decisions, and keep momentum. We value action over perfection and learn by shipping.

Take Ownership: We own outcomes, not just our individual work. We make decisions that move the company forward and follow through.

Communicate Openly: We communicate directly, seek to understand, and create clarity for others. Honest conversations help us move faster together.

Build Great Teams: We lead by example, empower others, and create healthy teams where people can do their best work.

Raise the Bar: We're always improving ourselves. We learn from feedback, consistently challenge ourselves to grow, and focus on the work that matters most.

Think Long-Term: We design for what's next. We create scalable systems, simplify complexity, and use AI and automation to amplify our impact.

What We're Looking For

We are looking for a senior product designer to help us design groundbreaking technology that will transform the machine learning ecosystem and fundamentally change how the world experiences software. With a diverse skill set spanning product, interaction, and visual design, you are able to create products that are a joy to use and add tangible value to our users.

You will collaborate across product and engineering to bring user flows and designs to life while working closely with users to test new ideas, conduct research, and gather feedback. You thrive in a fast-paced, start-up environment with a focus on speed, quality, and iteration from proof of concept to release.

You will be joining the Design Team and report to our Chief Creative Officer. This is a hybrid role based in our New York City office with in-office requirements of 2 days per week. We are open to San Francisco but NYC is the preferred location. The salary range for this role is $160,000-$200,000.

What You’ll Do

Collaborate with product and engineering teams to shape the user experience, interface, interactions, and visual design of new and existing features. Act as a key design partner in defining product strategy throughout the end-to-end development process.

Craft user journeys, flows, prototypes, and designs—sometimes starting from scratch, other times by refining early engineering prototypes or providing design enhancements and guidance as products evolve.

Proactively identify design opportunities and drive continuous improvement based on business objectives, user requirements, and customer requests.

Engage with the open source AI community and enterprise AI researchers and builders to understand real-world needs, workflows, and challenges—bringing those insights directly into the product design process.

Discover creative ways to eliminate friction and reduce papercuts through design, making it easier for users to onboard and utilize our platform from day one.

Advocate for scalable, user-centered design systems and processes that improve design velocity, consistency, and impact across the product.

What You’ll Need

5+ years of experience designing B2C software or technical platforms, preferably in developer tools, AI/ML, or SaaS environments

Strong portfolio showcasing end-to-end product thinking across UX, interaction, and visual design

Experience working with product managers, engineers, and researchers to iterate quickly and ship thoughtfully

Curiosity and initiative in engaging with the open source AI ecosystem, and a desire to understand the needs of both individual contributors and enterprise AI teams

Comfort working in ambiguity and across multiple product maturity levels—from early-stage prototypes to production features

Proficiency in Figma and modern design tools

Familiarity with technical concepts like machine learning, APIs, or cloud infrastructure (not required, but a plus)

Excellent communication skills, with the ability to present design rationale clearly and influence cross-functional teams

A mindset of continuous learning, user advocacy, and pragmatic design execution

Experience coding front-end is not required but a big plus!
