Product Designer, Mobile

At 10-4, we build mobile-first experiences for owner-operator truckers, helping them access fuel discounts and related services. We don't run feature factories or rigid top-down roadmaps. We follow a Product Operating Model (POM), where small, cross-functional teams are empowered to solve real user problems and deliver measurable business outcomes. We are an AI-forward organization and use an Agentic Development Life Cycle (ADLC) to build, test, and iterate quickly.

We are looking for a Product Designer to join the 10-4 mobile product team. This is a hands-on individual contributor role focused on end-to-end product design for our native mobile app. The designer will partner closely with a Product Manager and engineering teammates and will collaborate with the existing 10-4 designer as part of a broader UX organization. The work may support core fuel experiences or Beyond Fuel initiatives as team priorities evolve;

the role is not limited to a single feature area.

You will help shape the experience from discovery through launch: understanding customers, mapping user flows, developing and validating concepts, and delivering thoughtful mobile UI. Our ADLC workflow is iterative and AI-assisted, enabling close collaboration with Product and Engineering as ideas move quickly from prototype to production. You will use modern AI tools while applying strong independent design judgment.

• Own end-to-end product design for native iOS and Android experiences, from understanding the problem and exploring concepts through design delivery, launch, and iteration.
• Partner with Product and Engineering to discover and deliver solutions that are valuable, usable, feasible, and viable.
• Map user journeys and flows, develop an understanding of customer needs and personas, and translate complex workflows into clear mobile experiences.
• Conduct and contribute to hands-on UX research, customer conversations, and usability testing; use findings and product insights to inform design decisions.
• Create high-quality mobile UI and interaction patterns for native iOS and Android, balancing usability, visual craft, platform conventions, and engineering feasibility. Consider one-handed use, offline states, and accessibility.
• Contribute to intuitive mobile experiences for AI-driven capabilities, including agentic workflows, predictive actions, and smart context awareness, as product opportunities arise.
• Communicate design rationale, present work, share progress with stakeholders, and incorporate feedback constructively.
• Design within an Agentic Development Life Cycle (ADLC), collaborating with automated and AI-assisted workflows to prototype, test, iterate, and ship quickly.
• Collaborate closely with another designer on the 10-4 product and participate in the broader UX team's reviews, stand-ups, and working sessions.

• At least 3 years of professional product design experience.
• A track record of designing and shipping native applications for both iOS and Android.
• End-to-end, zero-to-one mobile app design experience, including meaningful ownership from the early stages of a product through launch. B2B or B2C experience is welcome.
• A shipped personal mobile app may satisfy the zero-to-one experience requirement if it was built and launched (for example, in the App Store); concept-only projects do not meet this requirement.
• Practical experience using AI in your design workflow. You can describe how you use AI today (for example, to generate design variants, synthesize research, or prototype) and how you evaluate, correct, or reject inaccurate or unhelpful output. Sound judgment matters more than familiarity with a particular tool.
• Strong communication and presentation skills, collaboration, receptiveness to feedback, and sound design taste and judgment.
• Bachelor's degree in a related field (such as design, human factors, marketing, business, or art), or equivalent experience.
• Authorization to work in the United States without current or future visa sponsorship.

• Experience designing interfaces for AI agents, copilots, or automation tools is a plus, but is not required.
• Experience with AI-enabled product development tools such as Claude, Cursor, or Codex.
• Experience working in an empowered, product-led operating model with close Product and Engineering partnership.
• Advanced Figma skills, including components, variables, and auto-layout, and fluency with Apple Human Interface…
