Job description

Project-Based | Remote | Limited Engagement

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 (a few hours total) focused on providing strategic architectural direction, not long-term implementation.

Job requirements

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

Strategy & Architecture

  • Design the Data “Plumbing”
    Build a scalable architecture connecting:

    • Historical data (Data Warehouse)

    • Real-time behavioral data (Streaming)
      → into a unified decisioning engine

  • Enable Developers
    Create clean technical abstractions such as:

    • React Context providers

    • Custom Hooks

    • 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

    • 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

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

    • 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

    • Asynchronous data flows

Engagement Details

  • Short-term consulting (a few hours total)

  • Fully remote

  • Focus: architecture & strategy only (no long-term implementation expected)

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
