We’re hiring our first dedicated Senior ML Ops Engineer to build the foundation that makes that possible. Today, our data scientists are building models. What we don’t yet have is the infrastructure, lifecycle automation, and production standards to reliably deploy and scale them. This role exists to change that. You’ll design and implement the ML Ops platform that enables training, deployment, monitoring, governance, and automation across our ecosystem. This is a 0 1 build. You’ll define tooling, establish standards, and integrate ML workloads into our AWS-native, event-driven architecture. This is not a research or modeling role. It’s a platform engineering role focused on productionizing machine learning systems. Your work will directly enable new benchmarking and anonymized data products that expand Built’s market opportunity. You’ll partner closely with Data Engineering, Data Science, and Platform teams to establish how ML systems operate across Built. What You’ll Do You’ll build and operationalize the infrastructure that allows machine learning to run reliably in production. Specifically, you will: • Architect and implement Built’s foundational ML Ops platform from scratch • Define and deploy reusable patterns for model training, deployment, monitoring, and retraining • Build CI/CD pipelines for ML lifecycle automation, including versioning and experimentation tracking • Stand up a feature store integrated with Snowflake and AWS to support structured and unstructured data • Implement model registry and governance standards to ensure reproducibility, auditability, and rollback capability • Integrate ML workloads into our event-driven architecture (Kafka, Kinesis) • Develop observability frameworks to monitor drift, performance, latency, and model quality in production • Automate ML infrastructure using Terraform and AWS-native tooling (SageMaker, Lambda, ECS, Batch, Step Functions) • Establish security and compliance standards across ML assets, including data lineage and access control • Mentor engineers on ML Ops patterns and deployment best practices This role is hands-on and foundational. You’ll be shaping how machine learning operates at Built for years to come. Skills & Experience We’re looking for a builder - someone who has personally designed and productionized ML infrastructure before. Must-Have Skills • Experience architecting and deploying ML systems in production environments • Deep familiarity with ML lifecycle automation (training, CI/CD, deployment, monitoring) • Strong AWS experience, particularly within ML pipelines (SageMaker preferred) • Proven experience building infrastructure-as-code solutions (Terraform) • Experience productionizing ML workflows end-to-end, not just optimizing existing systems • Strong Python proficiency • Experience integrating ML workloads with data platforms and event-driven systems • Solid SQL skills and familiarity working with Snowflake Nice-to-Have Skills • Experience implementing feature stores or model registries • Familiarity with data orchestration tools (Airflow, Prefect, Dagster) • Experience with ML observability tooling (Datadog, Prometheus) • Experience in regulated or financial data environments • Experience optimizing ML workloads for cost and scale • Exposure to Snowpark, Bedrock, or LLM orchestration frameworks What Will Make You Successful • You’ve built ML infrastructure from the ground up or led a major re-architecture • You’re comfortable working in ambiguity and defining standards where none exist • You think in systems and care about reliability, governance, and scalability • You collaborate well with data scientists and engineers to turn prototypes into production systems • You take
