„Horizon3.ai“ yra 2019 m. įkurta kibernetinio saugumo ir dirbtinio intelekto įmonė, kurianti autonominio įsiskverbimo testavimo programinę įrangą. Jos platforma „NodeZero“ padeda organizacijoms nuolat vertinti savo saugumo būklę, nustatant išnaudojamus atakų kelius debesijos, daiktų interneto ir vietinėse aplinkose. Kaip savitarnos SaaS sprendimas sukurta „NodeZero“ teikia įžvalgas apie pažeidžiamumus, nereikalaudama nuolat veikiančių ar prisijungimo duomenis naudojančių agentų. „Horizon3.ai“ įkūrė JAV specialiųjų operacijų ir nacionalinio saugumo sričių veteranai. Įmonė siekia padėti saugumo komandoms iš anksto pašalinti silpnąsias vietas, kol jomis dar nepasinaudojo užpuolikai.

NuotolinisVisas etatasVadovasPrivaloma Kalba: anglųDuomenų inžinieriusAprašymas
- Set the Database Platform roadmap with engineering leaders and the Pentest Platform organization.
- Make key database architecture decisions on schema design, partitioning, migrations, and scalability.
- Write design documents that give the team a shared technical foundation.
- Lead PostgreSQL expertise across query optimization, indexing, partitioning, replication, and connection pooling.
- Shape the graph-based asset model for hosts, services, credentials, and vulnerabilities across penetration tests.
- Lead schema reviews and ensure migrations are safe, reversible, and available without downtime.
- Develop tools and engineering practices for rigorous schema changes.
- Mentor P5 and P4 engineers through code and design reviews, and pairing.
- Coordinate with Data Ingestion, Asset Inventory, API Platform, and Security Research on data contracts, query performance standards, and architectural guardrails.
- Contribute production code and technical design documents as an individual contributor.
Reikalavimai
- Bring deep, proven PostgreSQL experience, including query planner internals, advanced indexing, partitioning, logical replication, vacuuming at scale, and connection pool tuning.
- Have experience designing large-scale multi-tenant databases, including row-level security and tenant isolation.
- Have experience with production schema migrations at scale, zero-downtime changes, backwards-compatible schema evolution, and tools such as Flyway or golang-migrate.
- Know graph data models and databases such as Neo4j or AWS Neptune, or graph-like relational patterns such as recursive CTEs, ltree, or adjacency lists.
- Write production application code in Go or Python.
- Show a track record of defining database architecture at scale, from design through production, across multiple companies or teams.
- Understand data architecture tradeoffs, including normalization versus denormalization, consistency versus availability, OLTP versus OLAP separation, and schema-first versus schema-last design.
- Be able to plan schema designs for the long term and substantially larger data volumes.
- Explain complex database decisions clearly in design documents, ADRs, and cross-team reviews.
- Have driven database standards across multiple teams without direct reporting authority.
- Have established database engineering practices, including schema review norms, migration safety standards, and query performance reviews.
- Have developed engineers through code review, pair programming, and architectural mentorship.
- Cybersecurity data experience, time-series databases, compliance, analytical queries or BI/reporting, and open-source database contributions are desirable.
- Have a consumer broadband connection of at least 25 Mbps.
