Why Thea Care?

At Thea Care, we are bringing the highest standard of dermatological skincare advice into every customer interaction.

Skincare shouldn’t be guesswork. We help users truly understand their skin — so they can confidently choose products that work for them over time.

We help skincare brands bring AI precision to customer interactions. Our white-label face scan delivers skin insights that are both scientifically rigorous and easy to understand. Behind the scenes, we run cutting-edge AI models trained on over 50,000 images, performing thousands of real-world skin analyses every week.

We’re already powering:

• 3,000 skin scans every week
• 6-figure ARR
• clients like NUXE Paris, Almirall, Cura Cosmetics Group, Klinge Pharma and other leading e-commerce platforms

We're bootstrapped and profitable. That means no investor distractions, just a relentless focus on building great product.

Why now?

AI unlocks skincare analysis that was never possible before. And consumers expect more personalized advice than ever. We’re turning smartphone cameras into dermatology-grade tools—and brands into trusted skin advisors. The space is wide open, and we’re moving fast.

We’re looking for a Founding Engineer to join us in building the future of skincare AI — no matter your background or gender identity, if you’re excited about our mission, we’d love to hear from you. While this is a founding-level role, day-to-day it’s a mix of senior full-stack engineering, product thinking, and a bias for shipping.

Your tasks

Tasks

About the Role

• Build product end-to-end (frontend + backend)
• You own the stack - You take responsibility over the codebase and move with urgency/high velocity.
• Write and connect APIs, work with Supabase and other microservices
• Deploy webapps to AWS, currently with infra in ECS and Amplify
• Collaborate closely with CEO and CTO on product development, access domain-knowledge from our dermatologist CMO
• Join a small, hands-on team where everyone still wears multiple hats

Your profile

Requirements

Tech Stack

• Frontend: Next.js, React, TypeScript
• Backend: Python, Supabase, Node
• Infra: AWS (ECS, Amplify), Clerk, GitHub
• AI: PyTorch, OpenAI
• Product Analytics: Posthog

We value smart pragmatism and customer-centricity over specific tech experience.

What makes you a great fit

• You’re a senior engineer with strong full-stack experience
• You love building real features for real users
• You’re comfortable owning things end-to-end (infra included)
• You’re product-minded and lean by default
• You want to work in person in Berlin with a small, driven team
• Bonus: you've worked with AR, computer vision, camera-intensive web applications, or Next.js before

What might make this less of a match

• You strongly prefer working fully remotely (we’re mostly on-site in Berlin + Potsdam)
• You’re just starting out and haven’t worked on software teams yet
• You only want to work with specific technologies instead of the entire development stack
• You thrive in large teams with more structure — we’re still lean and hands-on
