Senior Software Engineer - AdTech Bidding Platform / Traffic Shaping Specialist

This role expects AI fluency.

Directing AI tools well is core to how we work here.

A lot of what we build, from data exploration to model code, is done by steering AI and rigorously checking its output.

If that’s already how you operate, you’ll fit right in.

If it’s not, this isn’t the role for you.

Responsibilities

• 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.

Qualifications

• Are 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.
• Are 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 Ad Tech / 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.

• Can work fluently with AI coding tools.

Use AI assistants (Claude Code, Copilot, Chat GPT, 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.

Compensation & Benefits

In support of pay transparency and equity, the minimum and maximum full-time annual base salary for this role is $175,000 - $200,000 at the time of posting, with the potential of an incentive or bonus.

While this is our reasonable expectation this is not a guarantee of compensation or salary, 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.

The specific programs and options available will vary depending on the state, start date, and employment type.
