Product Designer Cover Letter Example

At Northfield Commerce I own end-to-end design for the checkout and payments experience serving 2.4 million monthly active users across web and mobile. I am applying to [Company name]'s Product Designer opening because I want to bring that scale of ownership to a team solving problems across an even wider product surface.

My checkout redesign increased completed purchases 14% and cut drop-off at payment 22%, validated through a staged A/B rollout, and the component library I built and maintain is now adopted by 6 product teams, cutting design-to-dev handoff time from 3 weeks to 8 days. Usability testing across 24 sessions and 3 rounds identified a navigation issue whose fix raised task completion from 61% to 89%.

I work daily in Figma from discovery through handoff, partner closely with PMs and engineers to frame a problem before sketching a solution, and I run my own usability testing rather than waiting on a dedicated research team. Mentoring two mid-level designers through weekly critique has been just as rewarding as my own project work, and both have since been promoted to senior.

I would welcome the chance to walk through that checkout redesign's A/B data and hear what [Company name] is tackling next. I can bring case studies and metrics to a first conversation. Thank you for considering my application.
