• Own technical strategy, architecture, and roadmap execution across multiple engineering teams.
• Lead, mentor, and hire engineering managers, leads, and senior engineers.
• Maintain high standards for system design, code quality, testing, and reliability.
• Drive capacity planning, performance optimization, and infrastructure scalability for high-volume security telemetry.
• Own operational excellence, including SLOs, incident response, and on-call practices.
• Make pragmatic architectural decisions balancing performance, cost, scalability, and delivery speed.
• Collaborate with the CTO, Product, Engineering, and business stakeholders.
• Scale engineering processes and teams through rapid company growth.

Required Qualifications

• Experience building and shipping production software, with at least 3 years leading engineering teams, including managers or senior/staff-level engineers.
• Strong technical depth in distributed systems, API platforms, search, applied AI, or large-scale infrastructure.
• Proficiency in one or more of Go, Rust, Python, or Java, with the ability to understand code in the others.
• Experience operating Kubernetes-based systems at scale, including performance tuning and production incident management.
• Proven architectural judgment, execution, hiring, and team development capabilities.
• Strong communication skills and comfort working in a fast-moving startup environment.

Nice to Have

• Cybersecurity experience, particularly with SIEM, SOAR, or XDR products.
• Experience with streaming frameworks such as Kafka Streams, Flink, Spark Streaming, Beam, or Arroyo.
• Familiarity with Elasticsearch, OpenSearch, ClickHouse, Druid, time-series databases, or graph databases.
• Experience building detection engines, real-time alerting systems, or data integration frameworks.
• Experience productionizing LLM/ML systems.
• Experience scaling engineering organizations from 20 to 50 engineers or through a similar growth phase.
