About
As a
Senior Backend Engineer
on Kikoff’s core credit-building team, you’ll shape the systems that define how our users build and maintain strong credit. You’ll work across the heart of our product experience—scaling the services that power credit actions, subscriptions, credit report processing, financial monitoring, and even drive our AI-driven smart credit coach. Your work will directly influence how millions of users understand, improve, and take control of their credit journey.
In this role, you’ll architect and evolve backend systems that must be highly reliable, intelligent, and adaptive as we grow. You’ll design user-centric credit-building workflows, integrate with major credit bureaus and financial data providers, and help refine the payment and subscription infrastructure that supports our product. You’ll also contribute to the technical foundation of our emerging AI coaching platform, collaborating closely with product and data teams to transform complex credit insights into clear, actionable guidance.
What You’ll Be Doing
Design and implement the backend systems that power Kikoff’s core credit-building experience , including credit actions, subscription flows, credit report processing, financial monitoring, and AI-driven coaching, while ensuring they scale reliably as we grow.
Own key domains within the credit-building platform , driving architectural decisions and ensuring high reliability, performance, and a seamless user experience.
Integrate
with third-party credit bureaus, financial data providers, and internal services,
building robust APIs and data pipelines

What We’re Looking For
5+ years of experience

system design, API development, and integrations , especially with third-party platforms or payment providers.
