About the role

Much of the traffic doesn't get bid on, wasting load on both sides.
Your job is to make the system smarter about what to send where.
Few engineering roles let one person see a problem from the hot path to the model and back.

Every ad request that hits our exchange runs through a real-time auction: a bidder decides, in milliseconds, whether to ask our demand partners to bid.
A lot of what we build, from data exploration to model code, is done by steering AI and rigorously checking its output.
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.

Each day can be different here at Nexxen, but some of the things you can expect to be doing daily are:
Have experience with AdTech / RTB, real-time or low-latency systems, columnar databases, A/B testing, or ML tooling.
Not all of these are required, but one or two would give you a great head start.

In support of pay transparency and equity, 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.

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.
