Responsibilities
- Define the technical vision and roadmap for Preply’s ML platform across teams, products, and business lines.
- Architect platform capabilities spanning experimentation, feature engineering, artifact management, training, deployment, monitoring, retraining, and governance.
- Design cloud-native infrastructure for distributed training and inference, including GPU environments, autoscaling, workload isolation, rollout strategies, and cost optimization.
- Set technical direction for ML CI/CD pipelines with testing, validation, security, performance checks, and release confidence.
- Establish observability standards covering model metrics, service health, alerts, drift detection, data quality, lineage, and business impact.
- Lead GenAI and LLM platform capabilities including gateway services, vector retrieval, prompt experimentation, evaluation, inference optimization, and model serving.
- Build platform abstractions, internal libraries, templates, and self-service tooling for ML Scientists, Data Scientists, and engineers.
- Partner with cross-functional leaders to align platform investments with experimentation velocity, reliability, cost efficiency, and user impact.
- Mentor senior engineers, influence architecture, raise engineering standards, and remove bottlenecks between ML research and production.
Requirements
- 9+ years of engineering experience with significant depth in large-scale ML, data, infrastructure, or platform systems.
- Proven experience architecting and scaling production-grade ML platforms for multiple teams, workflows, and use cases.
- Deep understanding of cloud-native architecture and end-to-end ML workflows, including experimentation, feature management, model versioning, training, deployment, monitoring, benchmarking, and lifecycle management.
- Strong hands-on experience with GCP or AWS, Kubernetes, distributed compute, observability, and infrastructure-as-code practices.
- Experience building enabling tools and platform capabilities for Applied Scientists, Data Scientists, and engineering teams.
- Strong technical judgment across reliability, scalability, security, cost, and developer experience.
- Excellent communication, cross-functional influence, architecture decision-making, and stakeholder alignment skills.
- Demonstrated ability to mentor engineers, raise engineering standards, and multiply team impact.
- Product-impact mindset focused on experimentation velocity, user experience, and measurable business value.
- Familiarity with LLM frameworks and GenAI infrastructure such as LangChain, LlamaIndex, vector stores, retrieval systems, prompt evaluation, model serving, or LLM observability.
