Our data engineers carry a lot of software engineering responsibilities, so we're looking for engineers who have strong Python coding experience, Pandas expertise, and solid software engineering practices.
What You'll Do:
Integrate large language models into production AI agent workflows - building structured-output pipelines with grounding, reference resolution, and evidence traceability.
Design and evolve APIs that serve risk Intelligence data to customers and external integrations.
Build and maintain data ingestion pipelines - owning the full lifecycle from extraction through loading and error handling.
Own reliability of async task processing systems — health monitoring, autoscaling, alerting, and incident response.
Build and maintain shared libraries and internal developer tooling that accelerate the entire engineering team.
Manage full service lifecycle — from standing up new services to decommissioning legacy ones.
Who You Are:
4+ years of experience in Data Engineering or Backend Engineering with a strong data focus.
4+ years of production Python experience - you write clean, testable, well-structured code.
Experience designing and building APIs (preferably GraphQL with Apollo Federation).
Experience in developing, maintaining, and ensuring the reliability, scalability, fault tolerance, and observability of data services in a production environment.
Have fundamental knowledge of data engineering techniques: ETL/ELT, batch and streaming, DWH, Data Lakes, distributed processing.
Comfortable with async Python patterns (asyncio, Celery, task queues).
Strong knowledge of SDLC and solid software engineering practices.
Familiar with infrastructure-as-code approach.
Demonstrated curiosity through asking questions, digging into new technologies, and always trying to grow.
Strong problem solving and the ability to communicate ideas effectively.
Self-starter, independent, likes to take initiative.
Familiarity with at least some of the technologies in our current stack:
Core: Python, Pandas, Polars, Celery, SQL (PostgreSQL), SQLAlchemy, Airflow, Docker, Kafka

APIs: GraphQL (Strawberry)
AWS: S3, Batch, RDS, DynamoDB, ECS, SQS, DMS, Lambda
Infra & Ops: Terraform, Datadog
Experience with or strong interest in AI-native development workflows (we use Claude Code as a core part of how we build software - from building internal tooling skills to debugging production issues.
What We Offer:
