[Hiring] Senior Software Engineer, Data Platform @Lithic

Role Description

We're hiring a Senior Software Engineer to join our Infrastructure team and build the backend services and APIs that make Lithic's data accessible across the organization. You'll spend roughly 80% of your time designing and building production backend services — REST APIs that serve data from Snowflake and other sources to internal teams and systems — and 20% supporting our data platform (pipelines, dbt, Airflow). You'll partner closely with the Analytics Engineering team to expose well-modeled data through clean, reliable APIs.

Job Responsibilities:

• Software Engineering (~80%):
  • Design, build, and maintain backend services and REST APIs that serve data from various SQL subsystems and other data sources.
  • Develop well-tested, production-grade Python services with clean API contracts, proper authentication, versioning, and error handling.
  • Work closely with the Analytics Engineering team to expose modeled data (billing, settlement, finance) through APIs that downstream consumers can rely on.
  • Build internal tooling and services that enable the broader organization to self-serve their data needs without writing SQL.
  • Participate in code reviews, system design discussions, and engineering best practices across the Infrastructure org.
  • Contribute to service observability: logging, metrics, alerting, and on-call practices for the services you own.
• Data Engineering (~20%):
  • Maintain and improve existing data pipelines that move data from source systems into Snowflake (Airflow, Airbyte).
  • Contribute to the dbt project alongside the Analytics Engineering team — model improvements, test coverage, and data quality.
  • Support data governance practices including access controls, lineage documentation, and data quality standards.

Qualifications

• Required:
  • Strong Python proficiency with experience building backend services and REST APIs.
  • Experience with web frameworks such as FastAPI, Flask, Django, or similar.
  • Solid SQL skills and hands-on experience with modern cloud data warehouses (Snowflake strongly preferred).
  • Experience designing and building production APIs with proper authentication, versioning, and error handling.
  • Familiarity with CI/CD, automated testing, and operational reliability practices.
  • A track record of shipping reliable, well-tested services in production environments.
  • Comfort navigating ambiguity and driving projects forward with minimal oversight.
• Preferred:
  • Experience with data pipeline development using tools like Airflow, Airbyte, Dagster, or similar.
  • Familiarity with dbt or similar transformation frameworks.
  • Experience in fintech, payments, or other financial services environments.
  • Familiarity with AWS services (Lambda, S3, RDS, API Gateway, ECS/Fargate).
  • Kafka or event streaming experience.
  • Infrastructure-as-code experience (Terraform, Pulumi).
  • Experience at a company processing high transaction volumes where correctness and reliability are non-negotiable.
