WORK HISTORY
Senior Product Designer @Onebrief
Onebrief is a defense tech startup building the modern planning platform for military staffs. I focus on the senior user segment most critical to enterprise adoption and contract renewal.In the last year I\'ve worked across the full product lifecycle: leading research, shaping strategy, and shipping features end-to-end. Highlights include- Developed personas and a product vision for senior command users that directly influenced go-to-market strategy and enterprise adoption goals- Documented the Joint Planning Process to identify growth opportunities and inform the long-term product roadmap- Designed Presenter View, giving briefers the tools to deliver confidently to senior leadership with speaker notes, annotation, and zoom built into the app- Designed and launched Version History, letting teams capture a snapshot of a plan before it evolves so nothing gets lost as conditions change- Designed the vision for in-app orders generation and an approval workflow, formalizing how products move through command review and creating a historical record that keeps staffs aligned- Led product and design initiatives, stepping into project management responsibilities and driving cross-functional coordination on an evolving team- Shipped steady UX improvements across the app that reduced friction in daily workflows and resolved long-standing issues that were quietly eroding user trustI use AI tools like Claude Code to move faster across research synthesis, prototyping, and documentation, compressing timelines without sacrificing quality.

ABOUT HEATHER PRIESTLEY
I design for people doing hard things in high-stakes environments.At Onebrief, I work at the intersection of complex military planning and modern product design, helping translate some of the most demanding workflows in the world into software that\'s fast, clear, and human. Over the last year, I\'ve led research that directly shaped our product direction, turning insights from the field into decisions that matter.I run the full design lifecycle: from ambiguous problem to shipped product. I use AI tools like Claude Code to prototype faster, synthesize research at scale, and automate the documentation work that used to take days. More time thinking, less time grinding.What I bring to a team- User research that moves product strategy, not just validates designs- End-to-end UI/UX design, from early concepts to high-fidelity systems- Prototyping and interactive mockups that communicate ideas before a single line of production code is written- Data analysis and synthesis to make sense of what users are actually doing- AI-augmented workflows that compress timelines without cutting cornersI care deeply about the humans behind the interface, whether they\'re energy customers trying to lower their bills or planners trying to make fast decisions under pressure. Good design makes both possible.Outside of work: I race Hyrox competitions around the world, do watercolor painting and needlepoint, and never stop exploring new places and new foods.
