Product Engineer (Software Engineer)

About the Role This is a full-stack product engineering role at an early-stage fintech company building consumer tools for cash advances, paycheck bridging, and credit building. You will work directly with product, engineering, and business leaders to ship high-impact features for a growing base of paying users, with a real effect on their day-to-day financial lives. What You'll Do Build product features end-to-end, including domain models, business logic, and API integrations. Drive data-driven, incremental releases toward bold product milestones. Use SQL and analytics tooling to evaluate product and system performance regularly. Test and debug complex state machines in an event-driven, pub/sub-heavy backend to ensure a seamless user experience. Ship to production daily through a rapid CI/CD process, 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 or Pub/Sub. Meaningful early-stage startup experience, rather than exclusively large-company or late-stage backgrounds. Strong knowledge of 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 writing SQL and using analytics tools to evaluate system and product performance. A track record of building consumer-facing products, not B2B only. Strong computer science fundamentals: algorithms, data structures, and system design. Background in a high-bar engineering environment, supported by a strong academic foundation. Experience with Go (Golang) deployed on GCP is a plus. Compensation & Benefits Salary: $120,000 to $200,000 USD annually. Visa sponsorship: Available. Location On-site in San Francisco, California, United States.
