Senior Software Engineer (Backend)
About the Team
The NR Lens team builds New Relic's Federated Data Platform - a distributed SQL query engine that lets customers connect external data sources (Snowflake, PostgreSQL, Google Sheets, AWS CloudWatch) and query them directly from New Relic.
You'll work on the distributed query execution layer, connector architecture, and API gateway that powers cross-source JOINs and unified analytics across customer data stores.
What You'll Do
- Design, build, and maintain cloud-native Java microservices in the NR Lens query path: SQL Gateway, Query Gateway, and data source connector plugins
- Develop and harden JDBC connector integrations - including connection lifecycle management, credential handling, query pushdown optimization, and security validation
- Improve query reliability and performance across a multi-tenant distributed SQL deployment serving 50+ customers
- Build and operate services on AWS (EKS, IAM/STS, S3) with infrastructure-as-code practices
- Implement security controls for user-supplied connection parameters (JDBC URL validation, SSRF prevention, hostname allowlisting)
- Build materialized view scheduling, execution, and lifecycle management features
- Design and implement deployment automation - canary deployments, progressive rollouts, observability integration
- Collaborate with the NRDB/Dirac team on the internal connector bridging federated queries to New Relic's native telemetry engine
- Participate in on-call rotation and incident response for production systems
What We're Looking For
Must Have:
- 5+ years of professional Java development .
- Strong experience building cloud-native applications on AWS.
- Experience designing and operating containerized microservices on Kubernetes
- Experience building and operating distributed systems at scale
- Familiarity with infrastructure-as-code (Terraform) and CI/CD pipelines
- Experience with AWS security patterns.
- Experience with observability tooling - defining SLOs/SLIs, dashboards, alerting
- Comfort debugging production issues across multi-service architectures
- Experience with gRPC or Thrift-based service communication
- Experience with GraphQL APIs
Nice to Have:
- Strong understanding of SQL query execution - parsing, planning, optimization, or execution engines
- Experience with JDBC drivers, connection pooling, and database connector development
- Experience with distributed query engines or SQL-on-anything platforms
- Experience developing plugins or connectors for distributed query engines (SPI-based architectures)
- Knowledge of RBAC/authorization systems in multi-tenant SaaS environments
