About Stripe

Stripe is a financial infrastructure platform for businesses. Millions of companies—from the world’s largest enterprises to the most ambitious startups—use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Stripe’s mission is to increase the GDP of the internet.

About the Team

Storage Integrations, part of Money Movement Integrations, builds and operates connections between Stripe and its banking and financial technology partners. These systems help businesses receive, hold, and move money through Stripe’s financial accounts and treasury products.

The role involves working with engineering, product, and financial operations partners across Stripe to build new integrations, extend existing ones to support new use cases, and develop shared components that make integrations easier to build and operate.

Responsibilities

Design, build, and maintain integrations with banks and financial technology partners, and extend existing integrations to support new money movement capabilities.
Own projects from understanding user needs and writing technical designs through implementation, testing, rollout, and production support.
Work across integration, platform, and product layers to make new capabilities available through consistent APIs and workflows.
Coordinate designs and reviews with teams that own each system layer.
Develop reusable components and tooling that reduce duplicated work across integrations and simplify future development and maintenance.
Build for financial correctness, security, and reliability through automated tests, monitoring, and safe failure handling.
Participate in the team’s on-call rotation after onboarding, investigate production issues across services, and improve runbooks and automation.
Contribute code reviews and documentation, and use AI-assisted development tools while taking responsibility for understanding, testing, and maintaining the resulting code.

The role is primarily focused on backend systems, with end-to-end ownership across partner integrations, shared infrastructure, product APIs, and workflows. Full-stack work involves following features across these layers to deliver usable capabilities.

Requirements

Minimum Requirements

4+ years of experience building, shipping, and maintaining backend software in a production environment.
Proficiency in Java or Ruby, or equivalent backend programming experience, including maintainable code and automated unit and integration tests.
Experience independently scoping and delivering software projects, making technical tradeoffs, and seeking input when needed.
Experience debugging distributed services across RPC APIs, asynchronous workflows, and persistent data.
Experience with technologies such as gRPC, Protocol Buffers, and Temporal, or equivalent systems.
Understanding of retries, idempotency, and failure recovery.
Ability to explain technical decisions clearly, collaborate across teams, and learn unfamiliar systems to deliver solutions.

Preferred Qualifications

Experience integrating with third-party APIs or building reusable libraries, adapters, and developer tooling used across multiple services or teams.
Experience building data-processing pipelines with Python, using technologies such as Apache Spark, Amazon S3, or Apache Iceberg.
Experience implementing financial-account or money-movement workflows, such as virtual bank account provisioning, incoming payments, reversals, or transaction reconciliation.
