Important Notice from Nexxen

Your Safety Matters At Nexxen, we care about the well-being of our current and future employees. We are aware of the growing number of online scams and fraudulent job postings, and we urge all job seekers to remain vigilant. Please be advised that Nexxen will never request payment (whether in cash, cryptocurrency, or any other form) as a condition of employment, offer positions that require you to invest in vague or dubious financial schemes, or promote roles that resemble get-rich-quick opportunities. If you receive a suspicious message claiming to be from Nexxen or encounter a questionable job posting associated with our name, please contact us at infosec@nexxen.com to verify its legitimacy. Your trust is important to us. Stay safe and informed.

What You'll Work On...

• The real-time bidder (Node.js) that decides which requests to forward to demand partners, and the throttling layer that acts on those decisions with near-zero latency.
• The job that aggregates traffic performance and produces the throttle layer — the bridge between our analytics and the live bidder.
• Data at scale: SQL over billions of bid requests and impressions to feed our research.
• Applied machine learning: gradient-boosted models with interpretability to rank which request features predict a bid, then turning those findings into real-time rules the bidder can use.

What We're Looking For

• A strong generalist, comfortable being dropped into an unfamiliar system and figuring it out.
• Can write and reason about production code, with careful attention to performance and correctness.
• Have expertise in at least one backend programming language and distributed systems.
• Fluent in SQL, or eager to become fluent, and like working with large datasets.
• Ask "why is this like this?" and keep pulling the thread until it makes sense.
• Have experience with AdTech / RTB, real-time or low-latency systems, columnar databases, A/B testing, or ML tooling.
• Can work fluently with AI coding tools. Use AI assistants (Claude Code, Copilot, ChatGPT, or similar) as a serious part of how you build — not to paste answers, but to direct the work, review what comes back critically, and move faster across unfamiliar territory than you could alone.

Pay and Benefits

The minimum and maximum full-time annual base salary for this role is $175,000 - $200,000 the time of posting, with the potential of an incentive or bonus. While this is our reasonable expectation, actual compensation is influenced by a wide range of factors including but not limited to skill set, level of experience, education, certifications, responsibility, and geographic location. Candidates hired to work in other locations will be subject to the pay range associated with that location.

We offer a variety of benefits, including medical, dental, vision, disability insurance, 401(k), EAP, parental leave, unlimited vacation, and company-paid holidays.
