Senior Software Engineer (Core Services)

Join Snorkel AI, a leading company in AI-native development. As a Software Engineer in the Core Services team, you will play a crucial role in shaping the data platform that powers the entire organization. You will be involved in a foundational architecture shift, designing and implementing event-driven data flows, building systems for data tracking and governance, and contributing to infrastructure cost visibility and optimization. This position offers a comprehensive benefits package, including health coverage, wellness stipends, unlimited PTO, and generous parental leave.

• Contribuer à la conception et à la mise en œuvre de flux de données pilotés par des événements, en veillant à ce que les événements circulent de manière fiable et que les échecs soient visibles et récupérables.
• Construire et maintenir la bibliothèque d'accès aux données partagées et les SDK utilisés par les équipes de la plateforme, de l'emballage et de l'API des ensembles de données pour lire et écrire à partir de plusieurs sources de données.
• Participer à la modernisation du flux de travail CI/CD, à l'intégration des outils AI SRE et à l'accélération de la vitesse de développement, de la fiabilité et de la qualité du produit dans toute l'entreprise.
• Hands-on experience with SQL and at least two of: Snowflake, Redshift, Postgres. You understand the performance characteristics of each and can write queries that don't bring down production
• Fluency with AI-assisted development tools (Claude Code, Cursor, or similar). This is a hard requirement — the team uses these tools daily and we expect engineers to leverage them for code generation, debugging, and investigation
• Experience with event-driven architectures — CDC, event buses, schema registries, at-least-once delivery semantics
• Familiarity with data orchestration tools (Prefect, Airflow, or Dagster) and transformation frameworks (dbt)
• Experience with Kubernetes. Our workloads run on EKS and you will deploy, debug, and scale services on K8s
• Experience building shared libraries or SDKs consumed by multiple teams — versioning, backwards compatibility, migration support
• 4+ years building platform infrastructure, data infrastructure, data platforms, or backend systems with significant data components. You have built and operated pipelines, data access layers, or ETL/ELT systems in production
• Experience with AWS — S3, RDS, EKS, EventBridge, IAM. Comfortable working in a Terraform-managed environment
• Understanding of data governance concepts — RBAC, PII handling, audit logging, data lineage
• Strong proficiency in Python. Our stack is Python-heavy across Prefect, FastAPI, dbt, and the SDK layer
• Prior work in regulated environments (SOC 2, FedRAMP, HIPAA) where compliance requirements shaped system design
• Experience with OpenTelemetry, ClickHouse, or similar observability infrastructure
• Experience with Ray for distributed compute workloads
