• Develop wireframes, prototypes, and high-fidelity mockups that align with user needs and business goals. 

• Work closely with internal team members to ensure seamless implementation of design elements. 

• Balance product design priorities with marketing design needs in a dynamic startup environment. 

• Stay updated on UX/UI best practices, design trends, and best practices. 

Marketing & Branding 

• Refine a cohesive brand identity for our company across digital and print media. 

• Support website design and development efforts to enhance user experience and brand engagement. 

• Create marketing materials such as website graphics, social media visuals, investor decks, and advertisements.

• Support the design of email templates, pitch decks, and other materials for fundraising and outreach efforts. 

Qualifications 

• Authorized to work in the U.S. 

• Located in or near Boston, MA or willing to relocate. 

• 5+ years of experience in UI/UX design. 

• Strong portfolio showcasing user-centered design work, including web and mobile applications (available online for review). 

• Collaborative and open-minded, eager to contribute to team success while continuously learning and iterating on designs based on feedback. 

• Ability to balance design thinking with business and marketing needs. 

• Excellent presentation and communication skills. 

• Experience conducting user research, usability testing, and implementing feedback-driven improvements. 

• Strong understanding of design principles, accessibility standards, and responsive design. 

• Ability to work both independently and collaboratively in a fast-paced startup environment and adapt to changing priorities.
