📋 Description

• Own the pacer and bidder • Go deep on the bidder and pacer stack map it end-to-end and identify at least one fragility worth owning on day one • Propose improvements to the bidder or pacer autonomously from problem definition through to 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 the theoretical foundations (probabilistic modelling, PID control theory) powering our approaches • Move at Vibe pace • Use AI tooling as a genuine force multiplier (not a crutch, not a checkbox) • Iterate in production, not in your head, we - ship, measure and adjust

🎯 Requirements

• 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. • 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
