Senior Software Engineer — Multi-Tenant SaaS Data Architecture

As we scale our SaaS platform to support increasingly complex enterprise environments, our graph-based data architecture is becoming a critical strategic pillar. We’re looking for a Senior Engineer with deep experience building and scaling graph-centric, multi-tenant data systems for large-scale SaaS products.

In this role, you’ll own the evolution of our graph data tier—designing performant, secure, and scalable graph models and storage strategies that enable rich relationships, deep querying, and intelligent insights across tenants.

This is a hands-on, high-impact role where you’ll shape the technical foundation of how we represent, store, traverse, and analyze interconnected enterprise data at scale.

• 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 even as topology size and complexity scale.

• Build backend services that interact heavily 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 ensure the graph layer meets 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.

• 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.

• Experience scaling graph-backed SaaS products for enterprise customers with large, complex topologies.

• Familiarity with distributed graph engines, distributed SQL, NoSQL, or horizontally scalable datastores.

• Experience building observability for graph workloads: query heatmaps, traversal metrics, cardinality analysis.

• Prior experience with major re-architecture efforts—e.g., moving from relational to graph, multi-tenant transitions, or large-scale migrations.

• You will define and deliver enterprise ready, graph-first architecture that powers the next generation of our platform.

• You’ll tackle high-leverage challenges around traversal performance, data relationships, tenant isolation, and scale-out strategies.

• Your work will directly influence how customers understand, visualize, and automate complex systems—unlocking entirely new product capabilities.

• Build foundational product features for an AI-first enterprise platform

• The opportunity to take ownership of critical systems that scale to millions of users

• A culture that values craftsmanship, autonomy, and technical excellence

• Competitive compensation, equity, and benefits package

• Work from our Flatiron District, Manhattan office, where you’ll be side-by-side with the founding team in a supportive, collaborative setting. Our team works on-site five days a week, growing and building together, and the location is easy to reach with plenty of public transportation options.
