Helena Chiacchierini
Product Designer
American Express GBT • Paris, France
Apr 2022 — Present
During my experience at Amex GBT, I was fully integrated into cross-functional Scrum teams, working at the intersection of user research, product strategy, and design execution. I led both qualitative and quantitative research, including user interviews, surveys, and data analysis via Amplitude, to uncover user needs and inform design decisions. I regularly facilitated ideation workshops and focus groups to align stakeholders around user-centered solutions and ran usability tests to validate hypotheses and iterate quickly. On the design side, I created wireframes and high-fidelity prototypes in Figma, ensuring consistency through active contribution to our design system, Glide. I also worked hand-in-hand with PMs and developers to balance user needs with technical feasibility. Beyond delivery, I contributed to fostering a strong UX culture within the organization by sharing best practices and promoting a user-first mindset across teams.
Product & Customer Success Specialist
Fairjungle • Paris, France
Jul 2020 — Dec 2021
At Fairjungle, an early-stage startup in the business travel sector, I contributed to the company’s growth by assuming a wide range of responsibilities across both the Product and Customer Success teams. I actively gathered and structured user feedback to help prioritize improvements and guide product evolution, while mapping user journeys and creating wireframes to support the development of the iOS application. In parallel, I onboarded and trained new clients, ensuring their technical needs were accurately reflected in our platform configuration. Collaborating closely with developers, I also followed up and tested bug fixes to ensure a seamless user experience. This hands-on role gave me a deep understanding of end-to-end product lifecycle management in a fast-paced startup environment.
Product Owner Assistant
American Express GBT • Paris, France
Jun 2019 — Sep 2019
As a Product Owner Assistant at Amex GBT, I supported four Product Owners in an Agile environment, contributing to the design and delivery of key features for one of the company’s B2B travel platforms (Neo). I led product discovery on two major projects by conducting interviews with client-side decision-makers and market research to benchmark competitors’ products. Working closely with client-facing teams, I identified business needs and translated them into actionable solutions, ensuring alignment with both user expectations and strategic objectives. I also collaborated with technical teams to define the roadmap, fostering a shared understanding of the product vision and business value. This experience strengthened my ability to navigate complex, cross-functional environments and bridge the gap between technical feasibility and business impact.
