Software Engineer, Data & Scalability Platform (4-8 Yrs)

Meet the Team

The Splunk Agent Resilience team is defining the future of AI resilience. Our team provides scalable, cost-effective evaluation and guardrails that ensure AI agents behave as intended, improving reliability and reducing risks. This unified approach empowers our customers to confidently deploy and manage AI-powered applications with enhanced observability and control.

As a Software Engineer on the Data & Scalability Platform team, you will build and operate the systems that store, move, and transform every span, metric, and evaluation result the platform produces. You will own features end to end design, implementation, testing, and production support across our data stores, streaming pipelines, and processing services, and grow into the performance and capacity work that keeps the data plane fast and cost-effective as it scales.

• Design, develop, test, and maintain backend services and data pipelines that operate at high scale.
• Build and extend features across the platform's data stores, relational, analytical/columnar, object storage, and caching including schema changes and safe migrations.
• Implement and tune the compute and pipelines that move and transform data, including stream processors, writers, and distributed worker fleets.
• Solve concrete problems in scalability, reliability, performance, and fault tolerance along the data path.
• Improve query and write performance through indexing, query tuning, and hot-path optimization.
• Contribute to load testing, profiling, and benchmarking, and turn the results into targeted optimizations.
• Add observability instrumentation so the components you build are measurable in production.
• Write clean, scalable code and comprehensive tests, primarily in Python, with flexibility to use other backend languages such as Go.
• Lead features from technical design through implementation, deployment, and production support.
• Debug production issues across data stores, queues, and services, and participate in code reviews, on-call, postmortems, and root-cause analysis.
• Drive improvements in engineering practices, automated testing, security, and reliability.

• Bachelor's degree with 4+ years of related experience, or Master's degree with 2+ years, or PhD with 0 years of relevant software engineering experience.
• Strong experience in backend engineering and building production-grade services.
• Hands-on experience with large-scale distributed systems, with a focus on scalability, reliability, and performance.
• Working experience with at least one database relational or analytical including schema design, query tuning, and safe migrations.
• Experience with streaming or queueing systems (e.g., Kafka, RabbitMQ, Pulsar, Kinesis).
• Strong proficiency in Python and experience with another backend programming language such as Go, Java, C++, or similar.
• Strong fundamentals in system design, distributed systems, APIs, data structures, algorithms, and concurrency.
• Experience with modern software engineering practices including CI/CD, automated testing, code reviews, Agile development, and production troubleshooting.

• Experience with a columnar, analytical, or time-series store (e.g., ClickHouse, Druid, BigQuery, Snowflake).
• Experience tuning queue consumers or async task workers for throughput — concurrency, batching, and backpressure.
• Exposure to performance work: profiling, benchmarking, or load testing real systems and acting on the measurements.
• Experience with cloud-native technologies, containerized environments (Kubernetes), and public cloud platforms (AWS, GCP, or similar).
• Experience with observability instrumentation and tooling (OpenTelemetry, metrics, tracing, logs).
• Familiarity with multi-tenant systems, quotas, or rate limiting.
• Experience with secure coding practices and privacy-by-design.
• Strong communication skills and a collaborative approach to design and code review.
