About the Role

Cranmore Executive Search is incredibly excited to support our client Amilis, as award winning scaling femtech company in their search for a Full Stack Product Designer. The successful candidate will join a passionate, mission-driven team working at the intersection of women’s health, data ownership, and digital care. Backed by early believers, Amiis are in beta and gearing up for public launch – they’re looking for a Product Designer to take their mobile app from functional to transformational.
The successful Full-stack Product Designer (UX/UI) will take ownership of the Mili mobile app experience end-to-end - from UX strategy and flow design to prototyping, testing, and final UI polish.
You’ll be responsible for shaping the product in its most formative stage, working alongside a PM and junior UI/graphic designer. Your north star? Make sure every woman using Mili knows exactly how to take control of her health, and why this app is worth coming back to.

What You'll Do
• Own the UX and UI of our mobile app - from concept through execution and iteration
• Redesign and evolve the current app experience based on real user feedback
• Run usability testing and design validation to uncover user pain points
• Translate product ideas into wireframes, user flows, and high-fidelity UI
• Collaborate with our PM and engineers to ensure clean handoffs and build-readiness
• Work with our junior designer to maintain visual consistency across features
• Build a maintainable, scalable design system over time
• Bring the app to launch (App Store-ready) and continue A/B testing post-launch

Requirements

Who You Are

  • 4+ years of experience designing mobile-first products (iOS/Android)

  • Ability to navigate ambiguity and thrive in fast-paced environments

  • Strong UX chops: You know how to structure flows, test them, and improve them

  • Great visual sense: You can bring UI polish and consistency to consumer products

  • User-obsessed: You love talking to real users, observing behaviours, and validating ideas

  • Autonomous and proactive: You’ve shipped products in early-stage teams before from ideation to launch

  • Clear communicator: You explain your rationale and collaborate with PMs and devs

  • Comfortable with ambiguity - and know how to create structure where needed

  • Excited to mentor junior talent and help shape a growing design culture

 

Desirable

  • Experience with healthtech, reproductive health, or femtech products

  • Familiar with dev handoffs or prototyping tools (e.g. Figma, ProtoPie, Maze)

  • Background in research, psychology, or behaviour design

  • You’ve taken a 0→1 product through launch and iteration before

About the Company

Amilis are closing the women’s health data gap — one structured dataset at a time. Their flagship product, Mili, is a mobile health companion helping women track cycles, fertility, hormones, and treatments. Its sister platform, Mili MD, empowers doctors to diagnose and treat patients more effectively, while generating structured, sex-specific health data that can transform clinical trials.

Today, over 53% of reproductive health conditions go undiagnosed, largely due to missing, siloed, or unstructured data. Amilis is solving this with AI-powered tools that help doctors and patients generate, use, and share real-world reproductive health data. Their dataset is already live with paying clinics and will power everything from better care to smarter pharma.
