Role Description Fetch is building the future of personalized consumer experiences. We’re looking for a Staff Machine Learning Engineer to serve as the technical lead for a high-impact ML team focused on personalization, relevance, and ranking. In this role, you will own the technical direction and execution for your team’s ML systems - driving high-quality architecture, guiding implementation, and ensuring models and infrastructure operate reliably at scale. You’ll partner closely with product and cross-functional stakeholders while remaining deeply hands-on in design and development. Responsibilities - Serve as the technical lead for a single ML-focused team, setting direction and raising the bar on engineering quality and system design. - Design, build, and scale ML systems supporting personalization, ranking, search, or ad-related use cases. - Own end-to-end architecture for your team’s services, including model training, evaluation, deployment, and serving. - Drive clarity in ambiguous problem spaces, translating product needs into scalable technical solutions. - Lead design reviews and ensure thoughtful tradeoffs around latency, reliability, experimentation, and maintainability. - Partner closely with product, data, and engineering stakeholders to deliver measurable business impact. - Mentor engineers through hands-on technical guidance, feedback, and example. - Use AI tools to accelerate development and improve system design, including: - Prototyping and validating ideas with LLM tools. - Leveraging AI for code iteration and experimentation. - Using AI assistants for architecture diagramming and design validation. - Exploring LLM-powered features where appropriate. Qualifications - 5+ years of industry experience in machine learning or software engineering, with demonstrated ownership of production ML systems operating at scale. - Proven experience building and scaling ML systems in personalization, relevance, search, or ad tech domains. - Strong hands-on expertise in distributed systems, data pipelines, and ML infrastructure. - Experience deploying ML models into production and operating them at consumer scale. - Demonstrated ownership of complex technical initiatives within a team. - Strong systems design skills with the ability to clearly articulate tradeoffs and implementation decisions. - Experience mentoring engineers and influencing technical standards within a team. - Ability to operate effectively in ambiguous environments and drive projects to completion. Preferred Requirements - Familiarity with LLMs and their application in personalization, feature generation, or search. - Experience with real-time or streaming ML systems. - Exposure to experimentation frameworks (A/B testing) and model performance measurement. - Experience bridging model development with real-time serving systems.

• Build and implement ML applications in structural biology, particularly around fine-tuning and extending foundational models like OpenFold, Boltz-2 and ESMFold. • Design and implement model extensions for specific tasks such as protein complex and binding affinity prediction, including data distillation, benchmarking, and evaluation pipelines. • Work with our customers and academic partners to define data preprocessing, selection, and benchmarking strategies for novel training tasks involving protein structures, complexes, and multimodal biological data. • Carry out case-studies associated with the above, providing scientific and technical expertise to our customers. • Be involved in the full project pipeline, from scoping through to results delivery and dissemination. • Design, build, and maintain scalable machine learning models and the pipelines needed for training, inference, and deployment in production. • Collaborate cross-functionally to ensure models address real-world drug discovery needs. • Contribute to publications or open-source contributions where relevant.

• Design, train, and deploy computer vision models to production with well-understood performance, latency, and cost characteristics. • Own the full ML pipeline: data preprocessing, feature engineering, model selection, training, evaluation, and deployment into sustainable inference services. • Conduct discovery spikes to validate feasibility and inform go/no-go decisions before committing to full development. • Integrate ML solutions with observability tooling, establishing and maintaining benchmarks to measure improvement and compare approaches. • Build automated, self-sustaining ML pipelines. Models should train, evaluate, and deploy with minimal manual intervention. • Inform build-vs-buy decisions with both technical rigor and business context, understanding when in-house models create competitive advantage vs. when vendor APIs are sufficient. • Collaborate with software engineers, data engineers, and product stakeholders to integrate ML solutions into CompanyCam's platform. • Communicate clearly with non-technical audiences about feasibility, requirements, and trade-offs of proposed solutions.
