Product Designer

Role SummaryThe Product Designer will play a key role in shaping the product experience and direction at Vietpay, working directly with the CEO and closely with product and engineering teams.
You will translate business and product goals into clear user journeys, wireframes, prototypes, and polished product experiences that the development team can confidently execute. This is a hands-on role that combines strong product thinking with excellent design execution, from early concepts through to production.
Beyond individual features, you will help define the overall product experience, challenge assumptions, understand user needs, and contribute to product strategy and prioritization. This role offers a clear growth path toward broader product leadership, including the opportunity to develop into a Chief Product Officer (CPO) role as the organization grows.
Key Responsibilities1) Product Experience & Flow Ownership· Own the end-to-end product experience, from understanding the business problem through defining how the product should work.
· Translate product ideas and business requirements into clear user journeys, product flows, wireframes, and prototypes.
· Think beyond individual screens and consider the complete customer journey, business goals, operational processes, and long-term product direction.
· Identify gaps, unnecessary complexity, and opportunities to simplify or improve the product experience.
· Define edge cases, alternative flows, and expected product behavior before development begins.
2) Product Thinking & Decision Making· Work directly with the CEO and leadership team to turn business ideas into practical product solutions.
· Challenge assumptions and proposed solutions when there is a better approach, using user needs, business context, research, and clear reasoning to support recommendations.
· Present and defend product decisions clearly to senior stakeholders.
· Help determine not only how a feature should look, but how it should work and why.
· Balance user experience, business objectives, technical constraints, and delivery timelines when making product decisions.
3) Product Discovery & Validation· Understand customer problems through research, feedback, data, and collaboration with business teams.
· Explore multiple solutions before committing to an implementation.
· Validate important product concepts through prototypes, user feedback, testing, or other appropriate methods.
· Use product metrics and customer feedback to evaluate existing experiences and identify areas for improvement.
4) Engineering Collaboration & Delivery· Work closely with engineering, sale and marketing teams to turn product concepts into buildable solutions.
· Produce clear flows, wireframes, prototypes, specifications, and supporting documentation that engineering teams can follow.
· Discuss technical constraints with engineers and adjust solutions without losing the original product intent.
· Review implementations and ensure the delivered product behaves as intended.
· Maintain clarity around product decisions, edge cases, and expected behavior throughout development.
5) Product Strategy & Leadership· Contribute to product strategy, prioritization, and roadmap discussions with the CEO and leadership team.
· Develop a strong understanding of Vietpay's customers, business model, market, and competitive landscape.
· Help establish product design and discovery practices as the organization grows.
· Take increasing ownership of product direction and cross-functional product decisions.
· This role has a growth path toward broader product leadership, including the opportunity to develop into a Chief Product Officer (CPO) role.
Job Requirements· 5+ years of experience in product design, UX, product management, or a closely related product role.
· Strong product thinking and demonstrated ability to design complex end-to-end user journeys and workflows.
· Ability to turn ambiguous business ideas into structured product concepts and clear flows.
· Strong communication and stakeholder management skills, including the confidence to challenge and defend product decisions with senior leadership.
· Experience working closely with software engineering teams and understanding how product decisions translate into implementation.
· Strong skills in wireframing, prototyping, and communicating product behavior. We care more about clarity of thinking and product decisions than visual design craftsmanship.
· Fluent English, with the ability to communicate directly and effectively with international leadership.
· Portfolio or case studies demonstrating the problems you solved, decisions you made, alternatives you considered, and impact of your work - not simply polished UI screens.
Preferred Qualifications· Experience working on fintech, payments, banking, SaaS, or other products with complex workflows.
· Experience participating in product strategy, discovery, roadmap, or prioritization discussions.
· Experience working directly with founders, executives, or senior business stakeholders.
· Comfortable using data, customer research, and experimentation to support product decisions.
· Experience taking a product from an ambiguous idea through discovery, definition, development, and release.
