The successful candidate will own the data ingestion and storage architecture, drive performance and scalability improvements, and keep the platform's code and dependencies secure.\nScope:\nDesign, build, and scale a high-throughput data platform supporting enterprise-grade performance monitoring and analytics.\n\nDevelop and optimize data streaming, processing, and storage solutions using technologies such as Kafka, Numaflow, ClickHouse, TimescaleDB, and Elasticsearch.\n\nCollaborate closely with platform, data, and engineering teams to deliver scalable, reliable, and high-performance solutions.\n\nDrive continuous improvement in platform performance, scalability, reliability, and operational efficiency.\n\nStay current with emerging technologies and best practices, with opportunities for professional development through certifications and technical training.\n\nKey Responsibilities\nData Platform Engineering\nDesign and build real-time data ingestion pipelines using Kafka and Numaflow to process high-volume platform telemetry and monitoring events.\nArchitect enrichment pipelines that transform raw event data into contextualized, actionable performance signals.\nOwn the persistent storage strategy across ClickHouse, TimescaleDB, and Elasticsearch, matching each data store to the right access pattern, and optimize queries, indexing, and partitioning to meet latency and throughput targets at scale.\nDesign data retention, rollup, and partitioning strategies that balance query performance with storage cost.\nTune the EP1 performance monitoring platform to handle growing data volume and query concurrency.\nIdentify and resolve bottlenecks across the full pipeline, from Kafka consumer lag to storage-layer query plans.\nDesign for horizontal scalability, including partitioning, sharding, and load distribution across data stores.\nEstablish capacity planning and load-testing practices for the platform's data infrastructure.\nBuild, Deployment & Collaboration\nSupport pre-deployment verification, including performance regression testing and security checks.\nCollaborate with QA to validate data pipeline correctness and system resilience under load.\nApply secure coding practices and participate in code reviews with a security lens.\nMaintain documentation of system architecture, data flows, and operational runbooks.\nPartner with engineering, data, and platform teams on design reviews and technical decisions.\nBasic Qualifications:\n8+ years of software engineering experience, including significant experience building and scaling data pipelines and/or observability platforms.\nStrong hands-on experience with Kafka (or similar streaming platforms) for high-throughput data ingestion.\nExperience with Numaflow or similar stream-processing/dataflow frameworks.\nDeep expertise in ClickHouse, TimescaleDB, or other time-series/columnar databases, including schema design and query optimization.\nExperience with Elasticsearch for search and analytics at scale.\nStrong query optimization skills across SQL, time-series, and search-oriented data stores.\nProficiency in multiple programming languages (Go, Java, Python, or similar).\nSolid understanding of container security, Kubernetes, and cloud infrastructure.\nExperience with CI/CD pipelines and build systems.\nWorking knowledge of security scanning tools and common vulnerability types (OWASP Top 10, CWE).\nBachelor's degree in Computer Science or related field, or equivalent professional experience.\nPreferred Qualifications:\nExperience designing multi-tenant, high-cardinality time-series data platforms.\nBackground in observability or monitoring platforms (metrics, logs, traces).\nExperience with stream-processing and data enrichment pipelines at scale.\nKnowledge of capacity planning, load testing, and performance benchmarking.\nFamiliarity with container security scanning and secure coding practices.\nExperience with API security testing and web application security.\nSecurity certifications (CEH, Security+, or similar) a plus, not required.\nData Platform &
