About the company

Based in the heart of Paris, Occi is a young French startup whose mission is to improve shopper experience by making it more customizable.
Occi enables physical stores to access previously untapped data about what shoppers do inside the store.

Who enters my store ? What product categories are they visiting ? What are the interests and needs of my customers ? We help retailers answer these questions by combining IoT, indoor geolocation, data fusion algorithms and AI.

Founded in 2015 by two students from Ecole Polytechnique, Occi is a fast-growing startup that has already convinced international retailers such as Carrefour, Auchan or Galeries Lafayette.

It is now developing a larger blockchain-based rewarding protocol, with which the existing solution will integrate as a dApp.

Job description

We are developing Universal Reward Protocol, a blockchain-based protocol where retailers can reward shoppers for multiple behaviors like simply visiting the store. By accepting to share their shopping data with the network, a shopper earns reward tokens, while the data is used by retailers to build redemption offers that best suit each customer’s needs. Shoppers can redeem their tokens through these exclusive and personalized offers.

As part of this marketing revolution, your responsibilities will be the following:

• Work closely with company leadership to define a product roadmap
• Have an active role in the design of the architecture of the protocol
• Be in charge of building the blockchain development team
• Implement the key features of the product

The benefit of a startup environment is that you will be able to work on the whole process. You will have autonomy in choosing the technical solution and in defining the KPIs in agreement with the technical team and the management.
We’re looking for a profile who is interested in intervening at an early development stage where most of the design decisions are still open, and willing to take on challenges with an ambitious roadmap.

Required skills

• You are deeply interested in blockchain technology. Ideally, you have a previous experience in the technological blockchain space.
• You are familiar with transaction scripting and smart contracts development.
• You have a working knowledge of Solidity and web3.js, and a desire to deepen it.
• You have previous professional experience with Javascript and/or a JS framework.
• You are fluent in English.

Appreciated additional skills

• Knowledge of the crypto-community
• Understanding of the mechanics of an ICO
• Crypto-investment activity
