About the Role You’ll join the Performance team that owns advertiser outcomes at Vibe. Bidding, pacing, and the prediction stack that drives both. You’ll report to Clément Schiano, Engineering Manager for Performance.
Three reasons you would want this job
CTV performance advertising is still being invented.
The auction dynamics, identity graph, and feedback loops are nothing like display or search. There’s no playbook to copy; you’ll be writing it.
You own the full decision loop.
From prediction to bid price to pacing, on a product that real advertisers depend on today. Your judgment shapes the direction. You’ll see the impact in the numbers within weeks.
The timing is right.
Past "does this work?" and into "how fast can we scale this?" Early enough to shape the architecture. Late enough that you’re not building on sand.
What You’ll Do
Own the pacer and bidder
Go deep on the bidder and pacer stack, map it end‑to‑end and identify at least one fragility to own on day one.
Propose improvements to the bidder or pacer autonomously from problem definition through design proposal.
Ship measurable improvements to CPx, pacing accuracy, or win rate within your first three months.
Raise the team’s ceiling
Distribute critical system knowledge: make the team faster and less dependent on any single person.
Challenge existing designs, including inherited ones, and push for cleaner solutions.
Deepen expertise in theoretical foundations (probabilistic modelling, PID control theory) powering our approaches.
Move at Vibe pace
Use AI tooling as a genuine force multiplier.
Iterate in production, not in your head. Ship, measure and adjust.
What You Need
Shipped backend systems in a strongly typed language (C++, Rust, Go, Scala, Java, or equivalent) at production scale.
Debugged distributed systems under real traffic: latency issues, consistency failures, the works.
Worked inside a DSP, SSP, or bidder: you understand auction mechanics from the inside.
Built or tuned pacing algorithms or PID controllers theory and implementation, not just awareness.
Solid grounding in probabilistic reasoning and statistical modelling you think in distributions, not just averages.
Nice to Haves
Experience in a scale‑up environment: you know what fast and resource‑constrained actually feels like.
ML systems in production: feature pipelines, model serving, not just training notebooks.
Real‑time data pipelines and low‑latency architectures at scale.
Redis, Kafka, or equivalent under meaningful load.
Our Values At Vibe, we run on three values:
Impact ,
Ambition , and
Urgency . We tie every goal to a real business outcome, think 10x rather than settling for good enough, and move daily rather than waiting for perfect conditions.
