Quick Summary
client wrapper versus Prebid Server (page weight versus cookie sync and bid-rate loss), where models sit in the bid path, what the Go gateways absorb versus PBS-Java.
One thing matters more than the rest for this particular role: Sparteo has taken zero external capital. There is no board pushing pivots, and decisions argued on merit and ROI actually stick. The whole chain is built in-house — Flashbid for header bidding, Meetscale as the SSP, Viously for video, FastCMP for consent, plus the analytics behind them. Nothing you own here is somebody else's black box.
An ad stack built entirely in-house, live on about 4,000 publisher websites.
Around 37 billion client-side bidding events processed per day.
More than 50 billion bid requests sent to demand partners every day across our platforms.
About 45 billion analytics events ingested into our big data storage every day.
Prebid Server in production in both official implementations, PBS-Go and the Vert.x-based PBS-Java, plus in-house Go OpenRTB 2.5/2.6 gateways.
Multi-cluster Kubernetes on-premise. Our own IAB TCF v2.2 CMP. An ad-integrity stack covering IVT, creative scanning and ads.txt / sellers.json / schain validation.

You make these calls and keep the stacks coherent across Flashbid, Viously, Meetscale and FastCMP.
You make the technical and build-or-kill calls across the domain's roadmaps. Product owns commercial priority.
Genuine ties escalate to the CTO — which should stay rare by design.
Latency and availability SLOs on the bid path, and wrapper Core Web Vitals across about 4,000 sites.
Dynamic floors and traffic shaping already run in production, built inside the Server-Side team. Their placement in the path is your call, with clearing-price, win-rate and viewability modelling as the next step.
You are the adtech expert of the company: client technical crises and the hard monetization questions from Product land on your desk.
You are also Sparteo's technical face outside — Prebid, IAB, industry events.
TCF/GPP purpose enforcement and consent quality, with FastCMP (our own CMP) in your scope.
DSA transparency signalling, supply-chain integrity (schain, sellers.json) and MFA/IVT rigor.
Buyers delist MFA inventory and data-protection authorities enforce TCF, so publisher-side quality is a commercial weapon — and here it belongs to engineering.
Claude Code, agents and workflows are how engineering works here, company-wide.
You practice agentic development daily and you know where AI accelerates and where it misleads.
The CTO is fully out of web programmatic. You are the recognized decision-maker, internally and with clients.
A unified client and server technical roadmap exists, is yours, and is shipping.
The bid-path p99 latency and availability SLOs (exact targets are on the dashboards you get in week one) held through traffic growth.
Your teams practice AI-native engineering by default, with you as the reference practitioner.
French speaker.
Large-scale OLAP analytics experience. ML shipped into a latency-bound bid path.
A visible Prebid open-source or IAB working-group track record.
Publisher-side privacy depth: consent-string quality, Safari and Firefox signal loss.
Video (VAST, CTV) or audio monetization.
🚀 You want to make an impact and move things forward collectively. Does hearing phrases like "Yes, but we've been doing it this way for years..." make your hair stand on end? We feel the same way: progress is made by questioning what already exists.
🧠 You solve problems pragmatically and analytically.
🏃♂️ You're looking for a fast-moving environment where your agility will be an asset. The 80-20 (Pareto) principle holds no secrets for you.
🎧 Your ability to listen encourages you to challenge and improve yourself on an ongoing basis.
