Team and Role Description

The Ads Measurement Org focuses on off-platform conversion signals ingestion, identity resolution, ads attribution, ads reporting, and providing high-quality data for machine learning model training. The team builds measurement products and systems that improve ad performance and integrate measurement data across engineering and cross-functional organizations.

You will be an engineering thought leader familiar with Ads Measurement and related ads systems end to end. You will design and deliver measurement solutions from ingestion through ad delivery, lead downstream adoption of measurement data, and be hands-on to solve problems where the team lacks expertise.

Responsibilities

• Stay current on state-of-the-art products and techniques; identify promising innovations and adapt them to Reddit’s platform and community.
• Convert business problems into engineering solutions that improve Ads performance.
• Create and drive Ads Measurement strategy at the org level, solving multi-year challenges.
• Design, implement, test, and launch complex product and infrastructure changes across the entire Ads stack.
• Lead large cross-functional projects end to end: concept, design, implementation, rollout, and performance validation.
• Identify top opportunities for Ads Measurement to improve Ads performance by diving deep into the platform, company priorities, advertiser needs, and downstream consumers of measurement data.
• Design and develop products and solutions that improve measurement data quality and integrate with downstream consumers (including modeling teams) from ideation to production deployment.
• Collaborate with engineering and cross-functional leaders, data scientists, backend and full-stack engineers, and machine learning engineers.
• Mentor staff engineers and leaders, share industry knowledge, and contribute to technical growth of the team.

Requirements

• Bachelor's degree (or foreign equivalent) in Computer Science, Economics, Statistics, Computer Engineering, Engineering, Applied Sciences, Mathematics, Physics, or a related field.
• At least 8 years of progressive and relevant Software Engineering experience, with a focus on Ads. Experience with ML modeling is highly desirable.
• In-depth experience with Ads measurement products and technologies such as brand lift, conversion lift, experimentation methodology, measurement foundations, third-party integrations, and privacy-aware systems.
• Experience developing creative solutions and coordinating large-scale, cross-functional efforts across teams and driving alignment.
• Experience advocating for Ads performance and working with cross-functional partners in product, engineering, privacy, and legal.
• Familiarity with Ads privacy challenges and regulations (GDPR, CCPA, ePD, ATT) and experience delivering high Ads performance within privacy constraints.
• Strong understanding of industry trends and a proven track record of adapting to signal loss due to evolving privacy constraints.

Benefits

• 100% remote work flexibility (offices in San Francisco, Los Angeles, New York City & Chicago for hybrid/in-office options).
• Comprehensive healthcare benefits and income replacement programs.
• 401(k) match.
• Family planning support and gender-affirming care.
• Mental health & coaching benefits.
• Flexible vacation & global days off.
• Generous paid parental leave and paid volunteer time off.
