- Comfortable working in agile, cross-functional teams
- Has current SC clearance, or is willing and eligible to undergo SC clearance
Desirable
- OpenAPI/Swagger
- Liquibase or Flyway
- Gradle
- Kafka
- Observability/monitoring experience
- Exposure to Kubernetes
- Some awareness of React/TypeScript
What we need from candidates
- Built Back End services or APIs themselves
- Worked on microservice-based systems
