<h2>Job Description</h2>
Are you passionate about modern frontend development and curious about the inner workings of digital advertising? We’re looking for a 
<h2>Senior JavaScript Engineer to join our dynamic team and take a key role in building and optimizing our in-house Header Bidding and ML-powered yield-management stack for publishers.</h2>
This is more than a traditional engineering role — we’re launching a new strategic direction in digital marketing, and we’re looking for someone who’s not only technically strong but also naturally investigative. You’ll lead data-driven experiments, explore new concepts, and help shape the next generation of AdTech solutions based on your findings. 
<h2>What you will do:</h2>
<ul>
<li>Set up a lightweight and efficient Prebid.js integration (under 30 KB) with support for 5 major ad bidders like Magnite and OpenX.</li>
<li>Build a high-performing sticky ad widget that refreshes smartly — only when the ad stays visible for at least 30 seconds and has 60%+ viewability.</li>
<li>Implement out-stream video ads (ads that play outside of a video player) using VideoJS and Google’s IMA SDK for seamless ad playback.</li>
<li>Configure and manage Google Ad Manager, including setting up line items, sending MCM (Multiple Customer Management) invites, and using automation scripts to streamline tasks.</li>
<li>Integrate a Consent Management Platform (CMP) to comply with privacy regulations, and develop a tool to validate ads.txt files, ensuring authorized ad inventory.</li>
<li>Create data views in BigQuery using SQL to analyze key monetization metrics like eCPM and Invalid Traffic (IVT), applying logic such as percentiles for deeper insights.</li>
</ul>
<h2>Requirements</h2>
Who you are:
<ul>
<li>Senior-level experience with JavaScript/TypeScript (ES6+, Webpack or Vite, DOM performance)</li>
<li>Solid understanding of HTTP, browser DevTools, and CORS</li>
<li>Proven experience building production-ready widgets or SPAs</li>
<li>Strong analytical and problem-solving skills</li>
<li>English B2+: able to read technical documentation and write clear tickets</li>
<li>Quick learner, comfortable navigating complex systems</li>
</ul>
We're building smart solutions for a fast-moving industry — and we want curious, driven engineers like you on board. Apply today!
