About the role

You'll take ownership of the backend behind a set of new member-facing gamification and engagement features in our white-labeled, premium Branded (mobile) App, shipping capabilities to 500k+ MAUs and driving growth for our B2B clients. This is greenfield, high-ownership work: new services and data models built on top of a large, existing product dataset.

What this mission offers?

1. A varied, high-ownership mission at the core of the product, with direct impact in the short and medium term.
2. A modern stack and real architectural challenges, such as new data models, event-driven systems, privacy by design.
3. A high-growth context with an engaged team and strong engineering standards.
4. Integrate with background/event-driven processing and notifications.
5. Ensure everything you build is scalable, reliable, and well-tested, end-to-end.

🎯 What will be your impact

1. Design and build new backend services and data models that power upcoming features in our mobile app.
2. Design new relational models from the ground up: weigh architecture options, align with our Core team, and document decisions (ADRs).
3. Build and evolve the APIs / BFF endpoints consumed by the mobile app.
4. Work with large volumes of existing product data to power new experiences, including backfills and migrations on high-volume tables.
5. Treat privacy and data protection (GDPR) as a first-class concern, opt-in flows, and safe multi-tenant data handling.
6. Integrate with background/event-driven processing and notifications.
7. Ensure everything you build is scalable, reliable, and well-tested, end-to-end.

🌟You would be great fit if you have:

1. Strong experience with Python (Django) and PostgreSQL at scale.
2. Genuine data-modeling depth, comfortable designing new relational models and running migrations on large, high-volume tables.
3. You thrive in ambiguity taking ownership of greenfield systems from day one. You explore the options, capture your reasoning in ADRs, and rally adjacent teams around a shared direction.
4. Rigorous about code quality, able to move fast without cutting corners on maintainability.
5. Strong communication skills in English.
6. Background in a startup or scale-up, ideally B2B SaaS.

Nice to have

1. Experience with consumer / member-facing products.
2. Experience with security- and privacy-sensitive features (GDPR, multi-tenant data isolation); able to reason about where data can leak and design against it.
3. Some React Native experience, to collaborate closely with our mobile engineers and occasionally contribute on the client side.
