Job description

A Developer AdTech at funda knows that having well-functioning technology that meets the needs of advertisers is the key to success (and profit). We are looking for a Developer AdTech with experience in platform development and integration with various technologies throughout the programmatic advertising space. You will be responsible for creating scalable solutions for displaying dynamic ads on our platform, and creating tools and data pipelines that help our sales specialists to launch and analyse campaigns.

Why are we looking for someone like you? Well, we’ll soon be facing some big challenges. The bar is set high: your brand-new Advertising Team wants to increase the relevance of advertising across the funda customer journey, by improving the quality of the advertising products. We have a high amount of traffic (over 5 million unique visitors every month) and a unique quantity of content, and you will take the lead in advertising development and setting the standard for the future.

Your job

You and your new team will set a proper baseline for how we do advertising on our platform. You will work on:

  • Implementing proprietary JavaScript Ad delivery libraries
  • Leading the technical development and implementation of new advertising products and services in conjunction with internal stakeholders
  • Maintaining all the technical advertising integrations with the funda platform (ad server, header bidding, event tracking etc.)
  • Providing technical support to the operations department in terms of online advertising products
  • Troubleshooting ad delivery or performance issues when they arise
  • Integrating new header bidding partners into our libraries as we onboard them
  • Implementing and maintaining the technical aspects of advertising data collection on the websites
  • Developing test cases for advertising partners and products to ensure their continued performance

Your Team

You’ll be part of a new core Advertising Team, whose biggest challenge will be to find the right balance between UX and advertising performance. This team further consists of another developer and a service owner; together, you will work with the sales department and AdOps. You’ll report to João, our Front-end Lead.


Your Profile

  • You have a bachelor's or other university degree
  • 3+ years of relevant work experience in a similar role
  • Strong vanilla JavaScript skills and understanding of the DOM, so you can write code that runs in browsers without frameworks

  • Experience with GPT (Google Publisher Tag)
  • Experience with header bidding libraries like Prebid.js
  • Experience developing and using A/B testing mechanisms
