This role sits within the Ads Content Understanding (ACU) team, which is crucial for optimizing content signals related to advertisements, ensuring brand safety, and understanding user intents during commercial interactions. The successful candidate will contribute significantly to monetization through practical and scalable machine-learning solutions.

Job Position and Responsibilities

The Senior Machine Learning Engineer (IC4) will take a lead role in the content understanding roadmap under the Monetization organization. Unlike purely research-oriented roles, this position focuses on developing and refining systems that have tangible business impacts. The responsibilities encompass a full machine learning lifecycle, including:

• Problem framing
• Data handling
• Modeling and evaluation
• Deployment and monitoring

The job requires designing scalable ML pipelines and advocating for responsible AI practices, covering significant areas such as bias, safety, and explainability in models being deployed in production. This role will also require collaboration and leadership skills, mentoring other engineers (MLEs and SWEs) involved in ML projects.

Specifically, the hired engineer will:

• Oversee the operation and excellence of ACU’s ML systems.
• Define key performance indicators (SLOs) for signals related to advertising.
• Create scalable content understanding capabilities for commercial contexts.
• Push for the advancement of modern ML practices within the ACU.

Required Skills

Candidates applying for this role must meet the following requirements:

• 5+ years of Machine Learning Engineering experience, focusing on production systems, ideally in content understanding or advertising realms.
• Demonstrated senior technical leadership involving architecture decisions and design reviews.
• Strong communication skills to articulate complex technical trade-offs across teams.
• Experience in deploying Natural Language Processing (NLP) models, ensuring business-relevant outcomes.

Preferred qualification includes practical experience with state-of-the-art LLMs in production settings, especially related to model labeling and distillation.

Technical Expertise

A solid background in popular machine learning frameworks such as PyTorch and TensorFlow is necessary, alongside proficiency in Python and an additional statically typed language like Go, Java, or C++. The role requires capabilities in designing ML systems and pipelines, encompassing aspects from offline training to online serving and experimentation, especially for high-traffic applications.

Compensation and Benefits

Reddit emphasizes transparency in salary which varies depending on role level and experience, with a provided range from $216,700 to $303,400 USD. This position is also open to equity compensation through restricted stock units and potentially offers some commission based on the role.

Additional benefits provided include:

• Comprehensive healthcare benefits and income replacement programs.
• A 401k plan with an employer match.
• Global benefits supporting various aspects of employee lifestyle, from workspace adjustments to professional development.
• Support for family planning and mental health coaching.
