Full Job Description

đź“‹ Description

  • • As a Senior Product Designer at Bitstack Technologies SAS, you will be at the forefront of shaping the user experience for a rapidly growing crypto-native bank. This is a unique opportunity to take ownership of the entire product design lifecycle, from initial concept and user research through to final delivery and iteration, working in close collaboration with a talented engineering team.
  • • Bitstack is on a mission to rebuild finance from the ground up, empowering individuals to achieve financial freedom through a more open and inclusive financial system. With over 300,000 users and backed by prominent investors like Y Combinator, 13books Capital, Stillmark, and Serena, we are a fast-paced startup that values extreme ownership, high velocity, and low-ego collaboration. Our product and design are paramount to our success in a competitive market.
  • • In this role, you will operate without traditional product managers, meaning you will be empowered to lead projects end-to-end. This involves defining the product vision, crafting the user experience, and driving the impact of your design decisions. You will be a critical element of project teams, working side-by-side with engineers in small, autonomous units.
  • • Your responsibilities will include collaborating closely with engineering, care, and compliance teams to deliver impactful projects that resonate with our user base. You will be expected to lead design initiatives from their inception to a polished, production-ready state, taking full ownership of their success and ensuring they meet business objectives and user needs.
  • • A core part of your role will involve creating high-quality mockups, interactive prototypes, and visually stunning assets with an exceptional eye for detail. You will also play a vital role in utilizing and enhancing our lightweight design system, ensuring consistency and scalability across our product offerings.
  • • Effective communication of design decisions is crucial. You will need to articulate your vision clearly, actively solicit and incorporate feedback, and champion the design perspective within cross-functional teams. This includes setting the bar for design quality and contributing to the overall design culture at Bitstack.
  • • We are looking for a designer who obsesses over details, thrives on solving complex problems, and prioritizes craft and impact over rigid processes. You will be instrumental in exploring new ideas, building prototypes, deploying internal builds, and ultimately shipping features that delight our customers.
  • • This position offers a significant opportunity for growth and influence. You will not only contribute to the product but also help shape the culture and practices of our design and product development processes. If you are a builder at heart, share our values, and are passionate about our mission to democratize finance, you will find a rewarding environment at Bitstack.
  • • You will be expected to engage in technical discussions, understanding the feasibility and implications of design choices within our technology stack. This collaborative approach ensures that our designs are not only beautiful and user-friendly but also technically sound and efficiently implemented.
  • • The ideal candidate will have a proven track record of delivering exceptional design solutions in a fast-paced startup environment. Your portfolio should showcase not only your aesthetic sensibilities but also your ability to solve complex user problems and drive product success. We value a pragmatic mindset, balancing the pursuit of design excellence with the realities of speed, business goals, and technical constraints.
  • • You will be a key player in fostering a culture of innovation and continuous improvement, contributing to the evolution of our design practices and the overall success of Bitstack Technologies SAS. Your ability to lead independently, from the initial discovery phase through to successful shipping, will be essential.
