Flutter Developer

We’re building Mercle, a proof-of-personhood startup creating the future of digital identity. Our product pushes the boundaries of mobile experiences by combining beautiful design, 3D elements, on-device ML models, and privacy-first architecture. We’re looking for a Flutter Developer who’s not just a coder, but a creator who cares deeply about user experience, security, and building for scale.

What You’ll Do

Build and ship cross-platform Flutter apps (iOS & Android) that can scale to thousands / millions of users.

Implement 3D elements and models inside Flutter apps to deliver unique interactive experiences.

Integrate and run Machine Learning models directly on-device, ensuring smooth offline-first performance.

Own features end-to-end : from design collaboration → development → testing → deployment.

Work with secure storage solutions like Android Keystore and iOS Keychain to protect user data and private keys.

Collaborate with designers and product thinkers to make apps feel polished and human.

Be part of a startup culture — take ownership, experiment fast, and grow with the company.

What We’re Looking For

Proven experience building apps used by large audiences (show us your portfolio / live apps!).

Strong knowledge of Flutter and deep understanding of iOS / Android ecosystems.

Experience integrating 3D graphics / models in mobile apps (Unity / SceneKit / ARKit / ARCore or equivalent is a plus).

Understanding of UI / UX design principles — you care about how things look and feel, not just if they work.

Ability (or willingness to learn fast) to run ML models locally using TensorFlow Lite, Core ML, or ONNX.

Familiarity with security & privacy best practices in mobile apps.

Enthusiasm for working in a fast-paced startup environment where you’ll wear multiple hats.

Bonus Points For

Knowledge of Web3 technologies (wallet integrations, dApps, or smart contracts).

Contributions to open-source Flutter libraries.

Passion for human-centred design and privacy-preserving technology.

Why Join Mercle?

Be part of a small, ambitious team shaping the future of digital identity.

Work on cutting-edge tech : 3D, ML, Web3, and privacy-first systems.

Ownership & impact — your work directly shapes the product used by thousands / millions.

A culture of experimentation and learning — we value passion and curiosity over titles.
