Remote work

Job summary

Scalable Path is seeking a Senior AI-First Full-Stack TypeScript Engineer with Postgres Focus to join the team remotely. You will own the data-centric system of record for an AI-driven loan origination and automated underwriting platform, directing the build and reviewing AI-generated code.

Your work will emphasize immutable schemas, row-level security, and reliable Postgres workflows. You’ll collaborate with a co-founder and a platform engineer, ensuring correct migrations, performance tuning,

Qualifications

• Senior full-stack TypeScript with a database center of gravity.
• Deep PostgreSQL—schema design, row-level security and grant-based access control, window functions, partitioning, and performance work at the query-plan level.
• Production event-driven design: transactional outbox or equivalent, idempotency, at-least-once delivery and what it actually costs you.
• Production AWS. We are AWS-native — EventBridge, S3, KMS, RDS/Aurora, Bedrock.
• You will work in a codebase that bans floating-point arithmetic and enforces a decimal type through lint rules, with contract and numeric invariants checked in CI.
• You need to be fluent enough in TypeScript's type system to work inside that discipline rather than around it.
• Strongly preferred: ledgers, payments, financial calculation engines, rules engines.
• Nice to have: exposure to Temporal or another durable-execution engine.

Responsibilities

• Own the system of record: append-only envelope storage for application facts, with access enforced at the database layer (grants + row-level security).
• Persist decisions and their complete evaluation traces, with snapshot hashing for byte-for-byte re-derivation.
• Own the headless intake API and contract-first integration path—the API contract as the artifact.
• Build the Postgres-based event path to AWS EventBridge with idempotency and delivery guarantees.
• Design and own the Postgres schema—partitioning, indexing, and query-plan-level performance for append-only tables.
• Own the historical application loader: ingest years of prior applications into the fact model.
• Own the data side of document extraction: schema, validation, confidence thresholds, routing.
• Build KPI and reporting surfaces over the system of record with as-of queries and history.
