Product Designer - Electronic Data Capture and Participant Experience (f/m/x)

Hi there!

HI THERE!

Our goal at Data4Life is to make the world a healthier place. Designers in our team make sure the software we build truly works for the people who use it - turning research ambition into experiences that participants, clinicians, and study teams can rely on.

D4L Collect is our sensor data collection platform for digital health studies -one place where researchers can simultaneously capture multimodal patient-reported and sensor data, from laboratory-grade devices to common wearables, and bring it all together as a unified, interoperable, GDPR-compliant dataset. With a no-code study builder, paperless consent management, and a participant mobile app, D4L Collect lets research teams set up and run their studies end-to-end while keeping full control of their data. We're now investing in D4L Collect's next chapter - deepening it for clinical research, enriching it with validated patient-reported outcome instruments, clinician data entry, richer EHR interoperability, and stronger regulatory rigor.

We're looking for a  Product Designer  to help us shape that next chapter end-to-end -from the participant mobile experience through to investigator and clinician workflows. You'll partner with our existing Product Designer on D4L Collect, and work shoulder-to-shoulder with product, engineering, QA, and regulatory to make D4L Collect the platform of choice for digital health and real-world studies. The position is full-time, based in Berlin / Potsdam, with an unlimited contract.

Your future role

• Shape the experience for D4L Collect's next chapter.  Design the participant- and researcher-facing surfaces of the platform's evolution - Patient Registry, electronic data capture (eCRF) for clinician entry, and a validated ePRO library - translating multi-year ambition into flows, interactions, and visual systems that work from the first study onward.
• Design for trust and compliance.  Make eConsent flows that participants actually understand, audit-trail interactions that don't slow researchers down, and accessibility (WCAG 2.1 AA as the working baseline) that's part of the design -not patched in during QA. Treat regulatory constraints as a design problem to solve, not a tax.
• Design new ways to collect and connect data . Build on the platform's sensor, wearable, and patient-reported foundation by designing first-class capture experiences for multimodal data including sound, images, and video, and by shaping how clinicians and study sites enter and review EHR data.
• Make clinical standards usable.  Translate CDASH, validated ePRO instruments, and emerging SDOH frameworks into UI patterns and workflows that investigators, sponsors, and study sites can pick up without a 200-page manual.
• Be a voice of users on the team.  Run discovery interviews, usability tests, and concept evaluations with participants, investigators, and study coordinators. Bring real user evidence into every design and prioritization conversation, alongside our existing Product Designer and our PM partners. Help the team ship a single, scalable design system.

What you need to succeed

• 2+ years building a  strong design craft  foundation - discovery, exploration, interaction and visual design, prototyping in Figma, and design system fluency - in an environment where engineering runs Scrum / Kanban while customers run multi-year, formally validated studies.
• 2+ years of  product, UX, or UX/UI design experience  in B2B SaaS, two-sided platforms, or regulated digital health solutions. Direct experience designing for clinical research software (EDC, ePRO/eCOA, eConsent, patient registry, or sensor-based study platforms) used by investigators, sponsors, study sites, or patients is a plus.
• Demonstrated  attention to   accessibility  (WCAG 2.1 AA at minimum) in shipped work, and working fluency with  research methods  - interviews, usability tests, concept evaluations - as a regular part of your design process.
• Comfort designing within regulated contexts , or curiosity to learn about this. A working understanding of HIPAA and/or GDPR as they apply to clinical trials is a plus.
• Bachelor's degree  in design, HCI, cognitive science, psychology, communication design, or a related field -or equivalent practical experience demonstrated through a strong portfolio.
• Languages : You're fluent in English. German at B2 level is a plus, especially for participant-facing research; a third language is a plus.
