About your new role:

This role owns the security product at its highest level of accountability: the API and UI that transform ingested security telemetry into a coherent, investigable picture for analysts. As a Staff Engineer, you won't just build this surface; you'll define how it should work, set the architectural direction that shapes it, and ensure the teams and systems that feed into it are aligned to a common standard. You'll work across a broad range of security data sources and partner with alert, classification, and ingestion teams to establish the data contracts that determine how security signal flows across the platform. This is full-stack work with a strong security-domain emphasis, and it requires someone who can operate at the intersection of system design, domain depth, and cross-functional influence.

Key Responsibilities:

• Own the security service API and UI end-to-end, including architectural decisions, system design, and long-term roadmap direction.
• Define and enforce the data contracts between security product teams and adjacent services, including alert, classification, and ingestion.
• Integrate and present a wide range of security telemetry: syslog, NetFlow, SNMP, firewall telemetry, OTel, EDR telemetry, and MDR ingest.
• Make cloud environments and their audit trails first-class within the product.
• Surface enriched entities, alerts, and topology in ways that map to how security teams actually investigate.
• Drive architectural decisions across ambiguous problem spaces where requirements are incomplete or competing.
• Establish technical patterns and standards that other engineers on the team can build against reliably.
• Mentor and develop engineers across the security product team, raising the quality and consistency of output across the group.
• Takes on additional responsibilities and projects as needed to support the success of the team and organization.

What you'll need for success:

Required:

• Production experience with Kafka and OpenSearch in high-volume, latency-sensitive environments.
• Deep familiarity with protobuf and contract-driven development at a multi-team scale.
• Broad security telemetry experience across syslog, NetFlow, SNMP, firewall telemetry, OTel, EDR, and MDR ingest.
• Strong working knowledge of cloud environments and audit trails.
• Familiarity with a range of security products including NDR, XDR, and similar.
• Demonstrated ability to reason across diverse data sources and derive usable network and system topologies from them.
• Experience operating with significant autonomy across ambiguous, cross-functional problem spaces.
• Proven track record of cross-team technical influence that drives alignment on architecture or standards beyond your immediate team.

Nice to Have:

• Hands-on experience with Memgraph or other graph data platforms.
• Familiarity with stream processing frameworks such as Flink.
• Experience working with LLM-based reasoning systems or providing structured context to LLMs for troubleshooting and investigation workflows.
• Prior work in security product companies or on security platforms with analyst-facing tooling.
