Lead Backend Engineer

WHAT WE DO AT MARKETPLACE DESIGN

As the place where all real estate actors gather (home seekers, owners, intermediaries, etc…), the marketplace’s primary success factor is to provide the highest standards in terms of safety, truthfulness, relevance, efficiency and quality of the interactions between each of these actors. Many factors have an impact on the quality of the marketplace experience, the most prevalent is the users quality, seriousness, and engagement of the marketplace themselves, and the content and information (sale / rent listings, buyers projects descriptions, agencies presentations …) they produce by the means of this use. 

The Marketplace Design teams’ role is about designing and developing all curation, penalty/reward, gamification, rating, scoring, and matching mechanisms that ensure the engagement of our users is constantly pushed up, and the quality of our content is constantly improving. That’s what we call Marketplace Dynamics.

As all of these capabilities are heavily data-powered, the Marketplace Design teams are also responsible for Data Governance, Modelling, Quality and the Data Platform and key Data-sets management for all of AVIV. We call that Data Operations.

Your Responsibilities

As the Lead Backend Engineer for Marketplace Dynamics, and working closely with the Product Managers and the Engineering Managers, you are responsible for the good development practices of your team, for the alignment with the company’s enterprise architecture, and to help the software engineers of your team to improve their technical and delivery skills.

As such, you create, adapt, and enhance the core capabilities of the marketplace (actor scoring, matching algorithms, classifieds quality, fraud & infringement detection, ...), and make them accessible across Aviv on all brands and all channels (web, mobile, email, ...), through APIs, libraries/SDKs, or event buses.

Here are some examples of projects that you will work on:

• Smart lead attribution and optimisation.
• Improvement of actors behaviours : response rate, response speed, engagement, …
• Classifieds recommendation engine.
• Classifieds smart sort order.
• Classifieds deduplication.
• Improvement of new classifieds alerts by avoiding wrong republication.
