(USA) Senior, Software Engineer

Position Summary...

We are building a first‑party, privacy‑centric advertising platform that unites retail data, smart‑TV inventory, and a growing CTV publisher network. Our mission is to deliver relevant, measurable ad experiences while giving consumers full control of their data. 

What you'll do...

As an Ad Tech Engineer on our CTV team, you will design, build, and scale low‑latency services that power server‑side ad insertion (SSAI), dynamic ad decisioning, and real‑time measurement across millions of smart TVs and OTT devices. You’ll collaborate with product managers, data scientists, privacy engineers, and DSP/SSP partners to create an end‑to‑end stack that bridges broadcast‑quality video with programmatic precision. 

Key Responsibilities 

• Ad Delivery & Decisioning 

• Develop microservices for ad selection, pacing, and frequency capping that handle >100 k QPS under <100 ms p99 latency. 

• Implement VAST 4.x / VAST 4.2, SCTE‑35 cue‑tone parsing, and OpenRTB 2.6 bid request/response logic for CTV.  

• Streaming & SSAI 

• Build and optimize HLS/DASH manifest manipulation and stitched‑segment workflows using AWS MediaTailor, GCP Media CDN, or an in‑house stack. 

• Ensure frame‑accurate ad breaks and seamless transitions across HDR, 4K, and variable‑bitrate profiles. 

• Measurement & Privacy 

• Integrate IAB OM‑SDK‑CTV signals, ACR fingerprints, and privacy‑preserving identifiers (PPIDs, EIDs) to attribute outcomes in real time. 

• Partner with the privacy team to apply differential privacy, on‑device ML models, and clean‑room pipelines (e.g., Secure Multi‑Party Computation) for closed‑loop ROAS measurement. 

• Programmatic Interfaces 

• Build APIs for header‑bidding adapters, Prebid.js/Prebid Server for CTV, and custom RTB auctions supporting deal‑IDs, first‑party audiences, and dynamic floors. 

• Work with supply‑side and demand‑side partners to certify integrations and troubleshoot bid‑stream anomalies. 

• Reliability & Observability 

• Automate rollouts via Kubernetes and GitOps; enforce canary releases and blue/green deployments. 

• Instrument distributed tracing (OpenTelemetry), anomaly detection, and SLA dashboards to guarantee five‑nines uptime during live sports and tent‑pole events. 

• Collaboration & Leadership 

• Translate product requirements into engineering design docs, influence architecture decisions, and mentor junior engineers. 

• Contribute to open‑source Ad Tech project
