WHAT WE’D LOVE YOU TO DO (AND LOVE DOING)

ML Subject Matter Expertise: Contribute to defining golden paths and best practices for building scalable, real-time systems.

Drive platform reliability: Define and implement SLOs for feature freshness, backfill correctness, and online/offline consistency; establish monitoring and alerting strategies; and help enable safe deployments and fast rollbacks.

Embed security by design: Implement identity and access management, secrets handling, network isolation, and data governance within platform workflows and self-service tooling.

Scale developer productivity: Champion automation and self-service (IaC, GitOps, CI/CD), create comprehensive documentation, and assist in designing onboarding programs that reduce time-to-first-success for scientists and engineers.

Provide technical guidance: Serve as a technical resource for complex ML infrastructure challenges, mentor junior engineers, and contribute to team-wide engineering standards.

Contribute to strategic decisions: Partner with product and engineering management on infrastructure decisions and contribute to the long-term infrastructure strategy.

Champion hiring excellence: Participate in hiring and developing engineers.

Proven ML platform experience: 3+ years of experience building and operating ML/MLOps or large-scale platform infrastructure with a strong track record on AWS (EKS) (or equivalent cloud). Experience with mission-critical systems is a plus.

Feature platform or data transformation expertise: Strong experience with feature engineering pipelines or the willingness to build that experience, including data contracts, schema evolution, and managing online/offline consistency. Prior experience with feature stores (e.g., Feast, Hopsworks, SageMaker Feature Store) or equivalent data transformation platforms for ML can make you an ideal candidate.

Containers, orchestration, and data systems: Hands-on with Docker, Kubernetes, and data/streaming technologies (e.g., Kafka/Kinesis, Spark/Flink) supporting both batch and streaming ML.

Model serving and low-latency systems: Practical experience with production serving stacks (e.g., KServe/Triton/TorchServe/custom), request shaping, caching, and traffic management.

Observability and reliability: Experience implementing metrics/tracing/logging; and participating in incident response, capacity planning, and post-incident reviews for ML systems.

Security and governance: Proficiency with IAM, secrets, network boundaries, data protection, and compliance within platform workflows.

Excellent collaborator and communicator: Comfortable engaging with engineers, scientists, and product teams; able to translate research and product goals into easy-to-use, reliable platform capabilities.

BONUS / NICE TO HAVE

Streaming and batch data for ML: Partner with customer teams to enable consistent online/offline features, robust data contracts, and schema/versioning practices that reduce drift and breakage.

Vector search and retrieval: Experience with similarity search and embeddings in production (e.g., FAISS, Milvus, OpenSearch KNN, pgvector) and their integration into ranking/retrieval workflows.

GenAI infrastructure: Experience with LLM serving, prompt management, or RAG architectures at scale.

If you think you have what it takes, we encourage you to apply even if you don\’t meet every single requirement. You may just be the right candidate for this or other roles.
