Senior Software Engineer - Integrations

About this role

Worth is looking for a Senior Software Engineer to join our Integrations Squad and own the systems that connect Worth to the outside world. Our squad builds and operates the third-party data integrations that power Worth's crosswalking and decisioning, the public API and SDKs ourcustomers build against, the customer-side integrations into banks, lenders, processors, and ISVs, and the internal connectors that glue Worth's services together. This is a hands-on engineering role for someone who thrives in production code, handles ambiguity with confidence, and raises the technical bar for the team around them. You will design and deliver the integration layer that 700M+ SMB records flow through, break down messy partner APIs and customer requirements into clean technical plans, and anticipate the rate limits, schema drift, partial outages, and data-quality issues that come with depending on dozens of upstream systems. Your impact will extend across the squad and the broader product through both direct contribution and technical leadership.

• Design, evolve, and operate Worth's public REST APIs and SDKs, with strong attention to versioning, backward compatibility, authentication, rate limiting, and developer experience.
• Break down ambiguous partner specs, customer integration requirements, and vendor edge cases into clear technical designs with well-understood tradeoffs.
• Write high-quality production code across backend and (where needed) frontend systems using Node.js, TypeScript, Nest.js, and React.js.
• Design and evolve PostgreSQL schemas that capture vendor responses, normalization layers, and crosswalking metadata, ...
