Product Engineer (Software Engineer)

About the Role This is a full-stack product engineering role at a consumer fintech company helping everyday people manage cash flow, access earned wages early, and build credit. You'll work closely with product, engineering, and business leaders to ship high-impact features directly improving users' financial wellbeing. What You'll Do Build product features end-to-end, including domain models, business logic, and API integrations. Drive deployment and iteration using a data-driven, incremental approach toward bold product milestones. Use SQL and analytics tools to evaluate product and system performance regularly. Test and debug complex state machines in an event-driven backend that relies heavily on pub/sub messaging. Ship to production daily through a rapid CI/CD pipeline, owning implementations end-to-end and responding to production incidents as needed. What We're Looking For 3+ years of experience building backend features end-to-end for production systems. Proficiency designing and consuming RESTful APIs, including authentication, authorization patterns, and rate limiting. Experience with event-driven architectures and message queues such as Kafka, Pub/Sub, or similar. Experience with relational databases (PostgreSQL or MySQL), including data modeling and query optimization. Hands-on experience with CI/CD pipelines, version control, automated testing, and code review processes. Experience developing consumer-facing products (not exclusively B2B). Experience debugging complex state machines in event-driven systems. Strong computer science fundamentals: algorithms, data structures, and system design. Meaningful experience at an early-stage startup or high-growth environment (not exclusively large enterprise or Big Tech). Experience with Go (golang) deployed on GCP is a plus. Must be based in, or willing to relocate to, San Francisco or Seattle for in-person work. Compensation & Benefits Salary range: $120,000 to $200,000 USD annually. Visa sponsorship is available. Location On-site in San Francisco, California (Seattle also considered). This is not a remote role.
