Your mission: build and lead our software

As our Lead Software Engineer and one of the first tech hire, you’ll be instrumental in building DermaScan’s product from the ground up. You’ll work hand-in-hand with the CTO and other key technical leaders — hardware & AI/ML.

You will also collaborate closely with healthcare professionals (doctors, dermatologists, nurses, patients) to turn real-world needs into cutting-edge digital tools.

At DermaScan, three major technical pillars drive our innovation:

→ Hardware — medical imaging devices,

→ Artificial Intelligence — computer vision models for dermatology,

→ Software — the clinical-grade digital platform.

You will own the Software pillar.

As our lead software engineer and founding team member, you will:

Architect, build, and scale the entire software stack.

Assemble and lead a team of engineers over time to shape the future of our product.

Work directly with our different users (doctors, nurses, patients) to translate real-world needs into seamless digital solutions.

Interface closely with the hardware and AI teams to ensure full integration across our systems.

This role is built for someone seeking autonomy, responsibility, and impact. You’ll be at the heart of all software decisions, and critical to bringing DermaScan’s vision to life.

What you’ll do :

• Own the technical architecture, coding practices, and long-term software roadmap.

• Develop and improve the web and mobile interfaces used by doctors, nurses and patients. Considering our technical choices (see details below) most of this work will be front-end.

• Integrate hardware devices into our software ecosystem.

• Implement security best practices from day one to handle sensitive health data.

• Stay connected with AI research and emerging skin imaging technologies to keep our stack cutting-edge.

• Recruit and lead the engineering team as we scale.

This job is your dream job if:

• You thrive on autonomy and want real ownership of what you build.

• You love creating elegant, simple solutions in complex environments.

• You are energized by building from scratch — not just maintaining what already exists.

• You can move fast, learn even faster, and make decisions in uncertain settings.

• You communicate clearly and respectfully across disciplines (technical, medical, operational).

• You are mission-driven and want your work to have a tangible social impact.
