Product Engineer (Software Engineer)

About the Role This is a full-stack product engineering role at a Series A fintech startup building consumer financial tools — think cash advances, paycheck boosting, and credit building. You'll work closely with product, engineering, and business leaders to ship high-impact features that directly improve users' financial wellbeing. What You'll Do Build product features end-to-end, including domain models, business logic, and API integrations. Drive incremental, data-driven releases toward ambitious product milestones. Use SQL and analytics tools to evaluate product and system performance against robust data pipelines. Test and debug complex state machines in an event-driven, pub/sub backend to ensure a seamless user experience. Ship to production daily via a rapid CI/CD process, owning implementations end-to-end and responding to production incidents as needed. What We're Looking For 3+ years 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 (e.g., Kafka, Pub/Sub, or similar). Experience with relational databases (PostgreSQL/MySQL), including data modeling and query optimization. Hands-on experience with CI/CD pipelines, version control, automated testing, and code review processes. Experience debugging complex state machines in event-driven systems. Prior experience building consumer-facing products (not B2B only). Strong computer science fundamentals — algorithms, data structures, and system design. Excellent cross-functional communication skills, including the ability to translate technical concepts for non-technical stakeholders. Nice to have: Experience with Go (Golang) deployed on GCP; background at early-stage or high-growth startups. Compensation & Benefits Salary: $120,000 – $200,000 USD annually.
