Role Overview
We are looking for an experienced Lead Architect to design and shape the “Intelligence Layer” of our React Native mobile application. This is a high-impact, short-term consulting engagement focused on providing strategic architectural direction, not long-term implementation.
About the Role
You will act as the critical bridge between raw data systems and our React Native engineering team. Your mission is to design a system that enables our developers to deliver personalized user experiences effortlessly — without requiring deep expertise in data science or CDP orchestration. You’ll define:
- Data flow and architecture
- System “contracts”
- SDK and integration strategy
What You’ll Do
- Design the Data “Plumbing”: Build a scalable architecture connecting historical data (Data Warehouse) and real-time behavioral data (Streaming) into a unified decisioning engine.
- Enable Developers: Create clean technical abstractions such as React Context providers, Custom Hooks, and API wrappers so the mobile team can easily consume personalization logic.
- Own Identity Resolution: Define a cross-platform identity strategy ensuring seamless “guest recognition” across web and mobile.
- Define the Tech Stack: Recommend and justify the optimal combination of CDP (Customer Data Platform), decisioning engine, and analytics tools, balancing power with ease of use.
- Establish Schema Governance: Create a global event taxonomy to ensure data consistency across the ecosystem.
About the Project
- New initiative (greenfield architecture).
- Focused on building a personalization intelligence layer from the ground up.
- Designed to empower an existing React Native team.
Why This Role?
- Shape a high-leverage architecture with immediate impact.
- Work on a modern personalization stack.
- Collaborate with a fast-moving mobile team.
- Deliver value quickly without long-term commitment.
- Compensation: 200 - 250 PLN per hour.
Must-Have Expertise
- Personalization Specialist: Proven experience designing closed-loop personalization systems (Collect → Segment → Decide → Deliver).
- The Orchestrator: Deep expertise in Customer Data Platforms (CDPs) and data routing strategies.
- Decisioning Systems: Experience with feature flagging, remote config tools, and dynamic UI rendering.
- Data Warehouse Fluency: Strong SQL skills and experience activating user segments from a warehouse.
- Mobile-First Mindset: Solid understanding of React Native architecture, performance constraints, offline-first scenarios, and asynchronous data flows.
