You will own architecture decisions, build a high-performing team, and elevate engineering rigor with strong design reviews and incident management.

Qualifications

• 10+ years of experience building and operating large-scale distributed systems, with substantial experience in backend infrastructure and real-time services.
• 5+ years of engineering leadership experience, including managing senior engineers and engineering managers in high-performing technical organizations.
• Strong technical depth in low-latency, high-throughput distributed systems, with the ability to guide architecture and make sound tradeoffs in performance, reliability, scalability, and developer velocity.
• Experience leading teams responsible for business-critical production systems with demanding uptime and performance requirements.
• Strong background with JVM-based backend systems, ideally Scala, with fluency in modern service-oriented architecture and distributed systems design.
• Experience with core backend infrastructure such as Postgres, Redis, Kafka and/or Kinesis, and cloud-native operational environments.
• Demonstrated success partnering cross-functionally with Product, Data Science, ML, and other engineering teams to deliver complex, multi-team initiatives.
• Track record of building strong teams, mentoring senior engineers, and creating environments where technical leaders can thrive.
• Strong operational instincts, including experience driving incident response, service reliability improvements, and engineering process maturity.
• High ownership, sound judgment, and a pragmatic approach to balancing technical quality with business impact

Responsibilities

• Lead the Rainmaker Ad Server engineering team, setting clear technical direction, team priorities, and execution standards across a high-scale, low-latency ad serving platform
• Own the engineering strategy and roadmap for ad serving capabilities, balancing near-term business commitments with long-term platform health, scalability, and maintainability.
• Partner with Product, Data Science, ML, and adjacent engineering teams to translate business goals into durable technical investments that improve delivery quality, monetization efficiency, and advertiser outcomes.
• Drive the architecture and evolution of distributed systems that power ad decisioning, auction logic, targeting, eligibility, pacing integrations, and serving reliability at large scale.
• Build and develop a high-performing engineering organization by coaching managers and senior engineers, growing staff-level leadership, and creating clarity in roles, expectations, and career development.
• Establish a high bar for engineering excellence through strong design reviews, operational rigidity, observability, incident management, and a culture of accountability and continuous improvement.
• Improve team execution by strengthening planning, prioritization, delivery predictability, and cross-functional alignment across multiple stakeholders and dependencies.
• Identify architectural bottlenecks, organizational friction, and process gaps, then lead pragmatic changes that increase velocity without compromising system correctness or reliability.
• Champion modernization where it matters, whether through platform simplification, performance optimization, infrastructure improvements, or better developer workflows.
• Experience in AdTech, including ad serving, targeting, auction systems, campaign delivery, forecasting, or measurement.
• Experience leading teams responsible for core ad decisioning or monetization infrastructure.
• Experience with Kubernetes, Terraform, and related infrastructure and deployment tooling in large-scale production environments.
• Familiarity with experimentation frameworks, real-time optimization systems, and data-intensive platforms used to improve serving decisions and monetization outcomes.
• Experience operating in streaming media, CTV, video advertising, or other high-scale consumer platforms.
