We combine technology with research-driven AI data development to create datasets, benchmarks, evals, and custom solutions for real-world AI systems. Founded out of the Stanford AI Lab in 2019, Snorkel works with leading AI labs and enterprises to move from better data to better outcomes. \nExcited to help us redefine how AI is built? Apply to be the newest Snorkeler!\nAbout the Team\nSnorkel's Platform organization owns the infrastructure and services that power everything at Snorkel - the pipelines, evals, access layers, event systems, governance, compute, and agent infrastructure that every product team and customer deployment depends on. We're a small team with a large surface area, and we're in the middle of a foundational architecture shift: moving from a single-database data path to a multi-source, event-driven agent first platform. The decisions being made now will define how our platform scales for years. You will be making them.\nAbout the Role\nWe're looking for Platform Engineers who combine strong infrastructure chops with real backend engineering depth. You'll build and operate the systems, services, and agent infrastructure that let product teams move fast and reliably - from data access layers and event-driven pipelines to the agent first architecture that will transform our ability to scale. Your work will directly allow us to scale the amount of high quality data we are able to deliver to our customers.\nWe are looking to grow our team of Platform Engineers, and are hiring at multiple levels.\nWhat You'll Do\nDesign and build agent infrastructure that allows us to safely and reliably speed up workflows from engineering and operation teams\nDesign and implement event-driven data flows using event brokers, CDC connectors, schema registries, event routing, and dead letter queues - ensuring events flow reliably and failures are visible and recoverable\nBuild the systems that track how data moves through the platform (lineage), enforce who can access what (governance and RBAC), and log what happened (auditing), including PII handling, retention policy enforcement, and audit infrastructure for enterprise and regulatory compliance\nSet strategy and architecture for build systems, testing frameworks, and CI/CD pipelines, and drive the transition toward robust, automated continuous deployment\nInstrument services with OpenTelemetry, define and monitor SLOs (query latency, pipeline success rates, service reliability), and build alerting that catches issues before they become incidents - you will be on-call for the systems you build\nContribute to infrastructure cost visibility and optimization - query cost estimation, workload right-sizing, and routing data to the most cost-effective storage tier for its access pattern\nCollaborate with engineers, product managers, and designers to bring consistency and high standards to codebases, infrastructure, and processes\nWhat You'll Bring\n5+ years building platform infrastructure, backend services, or data systems in production - you have built and operated pipelines, data access layers, distributed services, or ETL/ELT systems at scale\nStrong proficiency in Python, and experience designing REST APIs for internal services and developers\nStrong background in distributed systems and cloud platforms (AWS preferred) - hands-on experience with services like S3, RDS, EKS, EventBridge, and IAM, and comfort working in a Terraform-managed environment\nFamiliarity with data orchestration tools (Prefect, Airflow, or Dagster) and transformation frameworks (dbt)\nUnderstanding of data governance concepts - RBAC, PII handling, audit logging, data lineage\nTrack record of leading complex engineering initiatives, influencing stakeholders, and delivering measurable impact\nAbility to work in a fast-paced environment with strong technical communication skills\nFluency with modern developer tooling and a willingness to adopt new tools quickly - the team evaluates and integrates new tooling regularly to improve velocity and reliability\nNice to Have\nExperience building shared libraries or SDKs consumed by multiple teams - versioning, backwards compatibility, migration support\nExperience with event-driven architectures - CDC, event buses, schema registries, at-least-once delivery semantics\nExperience with OpenTelemetry, ClickHouse, or similar observability infrastructure\nPrior work in regulated environments (SOC 2, FedRAMP, HIPAA) where compliance requirements shaped system design\nExperience with Ray or similar frameworks for distributed compute workloads\nExperience in hyper-growth startup environments or scaling engineering orgs\nPrior experience as a Tech Lead, Team Lead, or hands-on Engineering Manager\nWhy This Role\nYou'll have meaningful ownership over the infrastructure and services that every product team and customer deployment depends on. This isn't a maintenance role - you'll be making foundational architecture decisions that shape how the company scales, with a team that cares deeply about reliability, craft, and moving fast without breaking things.\nSnorkel is proud to be an Equal Employment Opportunity employer and is committed to building a team that represents a variety of backgrounds, perspectives, and skills. Snorkel embraces diversity and provides equal employment opportunities to all employees and applicants for employment.\nActual compensation will be determined based on factors including skills, qualifications, experience, and geographic location.\nSalary range(s) for this role\n$220,000—$300,000 USD\nBe Your Best at Snorkel\nJoining Snorkel AI means becoming part of a company that has market proven solutions, robust funding, and is scaling rapidly-offering a unique combination of stability and the excitement of high growth. As a member of our team, you’ll have meaningful opportunities to shape priorities and initiatives, influence key strategic decisions, and directly impact our ongoing success. Whether you’re looking to deepen your technical expertise, explore leadership opportunities, or learn new skills across multiple functions, you’re fully supported in building your career in an environment designed for growth, learning, and shared success.\nSnorkel AI is proud to be an Equal Employment Opportunity employer and is committed to building a team that represents a variety of backgrounds, perspectives, and skills.
