Overview

We are looking for a Chief Software Engineer (AdTech) to design and ship ultra-low-latency ad serving systems that run on the hot path. You will lead technical direction across ad serving, SSAI, RTB, and identity while staying hands-on in code and mentoring senior engineers. Apply now to help maximize auction economics by balancing latency, cost, and correctness.

Responsibilities

  • Architect and implement hot-path code as a hands-on individual contributor
  • Define technical direction for ad serving, SSAI, RTB and identity through design docs you author, defend, and revise as constraints change
  • Coach engineers by raising the standard on code review, production rigor, and how the team evaluates latency, cost, and correctness
  • Own auction-level economics and quantify the revenue-per-thousand-impression impact of latency and AWS spend on the ad path
  • Represent the company's technical stance with partners such as GAM, SSPs, DSPs, measurement vendors and IAB Tech Lab
  • Set hiring standards for future engineers and participate in the loop for every senior+ AdTech hire
  • Drive production ownership for systems that serve hundreds of millions of ad requests per day
  • Make and stand behind decisions to reject features that threaten latency, correctness, or unit economics

Requirements

  • 7+ years of professional software engineering experience, including 5 years within an SSP, DSP, ad server, ad exchange, or CTV/OTT platform
  • Demonstrated production ownership of a platform serving at least hundreds of millions of ad requests per day
  • Deep expertise in at least one hot-path systems language (Go, Java, C++ or Rust), plus practical comfort in another
  • Strong fluency in JavaScript, Node.js and TypeScript for tooling, control-plane services, and the Prebid wrapper layer
  • Working-spec-level mastery of OpenRTB (2.x and 3.x), VAST (3 and 4), VPAID, VMAP and SIMID
  • Hands-on SSAI experience covering pod construction, manifest manipulation, ad stitching, and failure modes when delivering ads in HLS or DASH
  • Proven background in header-bidding architecture, including Prebid.js client-side, Prebid Server, wrapper design, and price-floor strategy
  • Engineer-level command of Google Ad Manager APIs, the line-item and key-value model, and known abstraction edge cases
  • AWS at-scale experience with EC2/EKS, ECS and Lambda, plus DynamoDB, Kinesis, MSK/Kafka and CloudFront
  • Solid distributed systems knowledge across queueing theory, backpressure, idempotency, hot-key mitigation and multi-region failover
  • Strong FinOps instinct with clear understanding of stack cost per thousand ad requests
  • Practical ability to use React where it intersects with ad-ops surfaces
  • Advanced proficiency in English (C1+)

Nice to have

  • Experience with FinOps Platforms
  • Strong Golang and distributed systems expertise
