Senior Manager of Database Platform, Horizon3

• Demonstrated experience leading teams that design, scale, and operate relational databases (PostgreSQL preferred) and hybrid data stores (graph, time-series, or document) in production at scale
• Experience defining schema migration strategies for high-velocity production environments with zero-downtime requirements
• Experience with multi-tenant data architectures: customer data isolation, row-level security, and data residency concerns
• Strong understanding of database performance: query optimization, indexing strategies, EXPLAIN analysis, and connection pooling
• Experience building or significantly growing an engineering team — including hiring, onboarding, and establishing engineering norms tailored for data-intensive systems
• Proven ability to define and instill engineering culture: rigorous schema review, data integrity standards, operational runbooks, and oncall rotation
• Drives high-impact architecture decisions rigorously — requires design documents, runs structured reviews, builds consensus across platform teams
• Able to partner effectively with a Principal Engineer and leverage their technical leadership without diminishing team ownership
• Proficient in Go, Python, or SQL (deep expertise)
• Production experience with PostgreSQL at scale: partitioning, logical replication, pg_bouncer/pgpool, read replicas
• Experience with AWS data services: RDS/Aurora, DynamoDB, ElastiCache, or equivalent
• Familiarity with graph databases (Neo4j, AWS Neptune) or time-series stores (TimescaleDB, InfluxDB) is a strong plus
• Kubernetes and containerized database operations — stateful workload management

Desirable

• You will lead the Database Platform team — the engineering team responsible for the data infrastructure that underpins every NodeZero pentest, finding, and report. NodeZero operates at scale: millions of discovered assets, tens of millions of vulnerability findings, and audit-critical data that our customers rely on to remediate risk
• The Database Platform team owns the design, operation, and reliability of our core data layer — currently PostgreSQL as the primary store and Neo4j for the asset graph, with time-series and analytical stores on the roadmap as NodeZero's data volume and use cases grow
• You will lead a team of ~8 engineers including a Principal Engineer, and you will build this team from a strong foundation into a fully staffed, world-class data platform organization
• Team Building & Culture: Hire, mentor, and grow the Database Platform team to full capacity. Establish database engineering norms and a culture of ownership for engineers who share responsibility for the most critical data layer in our stack
• Data Architecture: Partner with the Principal Engineer to define the technical direction for NodeZero's data platform — schema design standards, query patterns, migration strategies, and scalability principles
• Reliability & Operations: Own SLOs for database availability, query latency, and data integrity across production environments. Drive oncall maturity and runbook quality
• Data Modeling & Schema Governance: Establish schema review processes and data modeling standards. Ensure NodeZero's data model evolves cleanly as new pentest capabilities ship
• Cross-team Partnership: Collaborate with Data Ingestion, Security Research, and API Platform teams to align on data contracts, API design, and pipeline dependencies
• Act as a Product Owner: Translate data platform needs from Security Research and Product into a clear, prioritized engineering roadmap
