• Define and execute the team's charter, focusing on end‑to‑end customer interactions and the reliable display of ads globally.
• Develop and oversee state‑of‑the‑art observability systems for the Ad Display platform, tracking crucial metrics like reliability, viewability, latency, and providing deep debugging insights for ad creation teams.
• Provide governance for cross‑team ad rollout, including defining best practices and tooling for rigorous testing and deployment strategies (A/B testing, Canary deployments).
• Lead complex technical projects at massive scale, ensuring our solutions can handle millions of requests and maintain high performance worldwide.
• Collaborate intensely with a Staff Frontend Engineer, stakeholders from Ads layouts creation teams (designers, graphic specialists), and the core Bidding Platform backend teams.

Desired Experience:

• 2+ years in a technical leadership role (Team Lead / Engineering Manager).
• 10+ years in hands‑on Full Stack software engineering, with significant experience across frontend, backend, and with some understanding of DevOps aspects.
• Expertise in Web frontends creation and architecture.
• Experience with mobile application development (native or hybrid).
• Proven strong analytical thinking and data‑driven approach to decision‑making and performance tuning.
• Extensive experience with web performance measures and optimization at scale.

Nice to Have:

• Experience with leading complex technical projects operating at large scale (millions of users/requests).
• Experience in the AdTech/Real Time Bidding space.

We Offer:

• Projects focused on high code quality – solid code reviews are our standard;
• Collaboration within an interdisciplinary, self‑sufficient team including: DevOps (ensuring a great Developer Experience), database experts, backend developers, product designers, and QA engineers;
• Hardware and software tailored to your preferences – e.g. MacBook, AI tool licenses;
