About the role

Senior engineer role focused on graph-centric, multi-tenant data systems for a SaaS platform. Owns evolution of the graph data tier, including modeling, storage, tenancy, performance, and governance in a high-scale enterprise environment.

Responsibilities

  • Architect, evolve, and optimize our multi-tenant graph data model, including node/edge schema design, relationship modeling, partitioning, and traversal strategies.
  • Define and implement tenancy models for graph storage—balancing shared-graph vs. tenant-isolated subgraphs, hybrid partitioning, or database-per-tenant graph deployments.
  • Develop data architecture for graph sharding, indexing, and high-throughput traversal, ensuring low-latency queries as topology scales.
  • Build backend services that interact with datastores, including APIs, data-access layers, ingestion workflows, and graph mutation/query pipelines.
  • Optimize query performance through indexing improvements, caching of subgraphs, tuned traversal patterns, and distributed graph execution.
  • Own decision-making around multi-tenant graph architecture: tenant boundaries, access control models, resource isolation, and performance fairness.
  • Implement tooling for onboarding, migrations, tenant provisioning, graph expansion, and lifecycle management.
  • Collaborate across product, infrastructure, and security teams to meet enterprise SLAs, security, and compliance requirements.
  • Establish standards around modeling, relationship semantics, data governance, and observability for graph workloads.
  • Build visibility into performance and health—metrics, dashboards, anomaly detection, traversal cost profiling, etc.
  • Mentor engineers in database fundamentals, scalable SaaS data patterns, and distributed systems thinking.

Qualifications

  • 5+ years of professional software engineering experience in production SaaS environments.
  • Hands-on experience designing, scaling, or operating multi-tenancy databases in production.
  • Strong understanding of graph modeling, schema design for nodes/edges, indexing, and query/traversal optimization.
  • Proficiency in a modern backend language (Go, Python, Java, Node.js, etc.).
  • Solid grounding in distributed systems concepts, partitioning, caching, and performance optimization.
  • Experience making architectural decisions in fast-changing, high-scale environments.
