Senior Software Engineer, Identity Graph

What You'll Do

• Ingest and normalize heterogeneous public records into the graph, owning the full pipeline: ingestion to normalizer to repository to API surface.
• Build and maintain entity resolution and linking systems - matching the same business or person across sources where keys don't line up, names are misspelled, and addresses are formatted six different ways.
• Design and ship customer-facing APIs for search, lookup, monitoring, and webhook delivery - built for engineers who'll be live in production within a day of signing up.
• Own schema design and zero-downtime migrations on a database hot 24/7.
• Optimize performance and scale: query patterns for 10x volume, ingestion pipelines that finish before the next batch arrives, API latencies that don't drift as the graph deepens.
• Build multi-tenancy and access control: every query in the system scoped by org/user/permission at the data layer.

Minimum Requirements

• Shipped product features that touched ingestion to storage to API to customer, end-to-end, in production.
• Owned a Postgres schema that real money or real decisions depended on, and stayed on top of its evolution.
• Strong async Python with experience running async services at scale.
• Deep Postgres expertise: schema design under live load, EXPLAIN ANALYZE as a reflex, zero-downtime migration tooling.
• FastAPI (or close equivalent): shipped real APIs with auth dependencies, OpenAPI contracts, and structured response models.
• Built multi-tenant APIs where access control is load-bearing and scoped correctly at the data layer.

What Sets You Apart

• Entity resolution / record linkage / fuzzy matching at scale.
• Search infrastructure - full-text, fuzzy, or vector - kept in sync with a Postgres system of record.
• KYC/KYB/fraud/underwriting data-pipeline experience.
• Address parsing/normalization at country scale.
• Webhook delivery infrastructure: retries, signing, idempotency, and ordering guarantees.
• GCP experience with Cloud Run, Cloud Tasks, Cloud SQL, and batch pipelines.
