As a Senior Machine Learning Engineer, you will design, build, and operate production machine learning systems that directly impact revenue, efficiency, and viewer experience at global scale. This is a hands-on, production-focused role, ideal for an experienced ML engineer who enjoys owning complex systems end-to-end, partnering closely with product and engineering teams, and delivering measurable impact in low-latency, high-throughput environments operating at billion-request-per-day scale.
This role is not research-only. Success is measured by production outcomes, system reliability, model performance, and continuous iteration based on data and feedback.
Daily, you should bring:
- Strong technical ownership and accountability for production ML systems
- Effective collaboration and communication across engineering, product, and data partners
- Comfort operating in ambiguity and translating loosely defined problems into scalable solutions
- A continuous improvement mindset with attention to performance, reliability, and cost
- The ability to define and use technical and operational metrics to measure system and model health
Responsibilities:
- Apply modern machine learning techniques to advertising use cases such as inventory forecasting, pricing, targeting, and efficient ad delivery
- Design, implement, and iterate on ML solutions from experimentation through production deployment and ongoing optimization
- Build and scale ML architectures that balance model quality, latency, throughput, reliability, and cost
- Design and maintain feature pipelines and feature stores supporting both real-time inference and offline training
- Own major components of the model lifecycle, including experimentation, validation, deployment, monitoring, and iteration
- Analyze experimental results and partner with product and engineering stakeholders to support data-informed decisions
- Ensure models are observable, debuggable, and explainable in production environments
- Implement monitoring for model performance, drift, bias, and overall system health
- Contribute to engineering excellence through high-quality code, sound system design, and operational best practices
- Provide technical guidance through code reviews, design discussions, and knowledge sharing
Basic Qualifications:
Bachelor's degree in Computer science or related field of study
5+ years of software engineering experience
Minimum 3 years of hands-on experience developing and deploying machine learning systems in production
Strong knowledge of machine learning fundamentals, mathematics, and statistics
Experience operating ML systems in low-latency, high-throughput environments
Strong communication and collaboration skills with both technical and non-technical partners
Solid foundations in algorithms, data structures, and numerical optimization
Proficiency in Python (primary), with experience in Java and SQL
Experience with modern ML frameworks and tooling such as TensorFlow, PyTorch, and Hugging Face
Experience with one or more of the following:
- Deep learning methodologies (e.g., sequence-based or representation learning models)
- Transformer architectures (e.g., BERT, GPT, ViT) for NLP and/or vision
- Multimodal embedding techniques across text, image, audio, or structured data
- Large language models and related evaluation methodologies
- Retrieval-augmented generation (RAG) architectures
Experience building systems on cloud-native infrastructure and distributed platforms
Proven ability to thrive in a fast-paced, data-driven, and collaborative environment
Preferred Qualifications:
- Experience in digital video advertising or the digital marketing domain
- Experience with programmatic advertising or real-time bidding platforms
- MS or PhD (preferred) in Computer Science or equivalent practical experience
