with product, data, and finance teams to ensure payments are seamless, compliant, and insightful. Contribute across the stack
on
user-facing
experiences tied to core subscription payments and related features - from checkout and repayment flows to account management. Extend payments capabilities
beyond Kikoff's own products to support external transaction data, helping users build a holistic picture of their finances. Enhance observability and reliability , introducing monitoring, alerting, and fault tolerance into payment-critical systems. Support adjacent product areas , contributing to shared systems and features beyond payments as part of a cross-functional engineering team. What We're Looking For 5+ years of experience
building and scaling production systems. Experience with
Ruby on Rails

experimentation and optimization , using data and iteration to improve customer outcomes. Strong
product sense
- you care about building the right thing, not just building it right. A
