Paris, Île-de-France Collective Temps plein

At Payflows, we give finance teams the tools to reclaim their time and energy. Our platform weaves together banking connectivity, payments, AI, and procurement so they can ditch the busywork and focus on what really moves the needle.

Why Join Us?

We're a small, mighty team who've earned our stripes at Airbnb, Luko, BNP Paribas, and Facebook. It's not always easy—things move fast, and we expect a lot—but if you're hungry for impact, you'll find it here.

We're builders at heart. We move fast, think deeply, ship often — and we're always hungry to learn more. You'll collaborate closely with product and tech to craft elegant backend systems that scale as fast as we do.

What You'll Do

Own & Build: Take charge of core services, write clean and scalable code, and influence architectural decisions.

Set the Bar High: Champion coding standards, thorough testing, and top-tier code reviews.

Mentor & Elevate: Guide junior engineers, provide constructive feedback, and lead internal workshops.

Optimize & Improve: Spot performance bottlenecks, improve CI/CD pipelines, and push for smarter tooling.

Advocate for Maintenance: Identify and address technical debt, making the case for long-term stability.

We value ownership, clarity, and kindness. We care deeply about the craft, but we don't take ourselves too seriously

‍ What we're looking for

6+ years of experience with Python or any other OOP language

Backend expertise: APIs, microservices, architecture best practices

Databases & SQL: Data modeling, query optimization

Git lover: Comfortable with version control and code reviews

Pragmatic engineering mindset: Build, test, refine, simplify—smart shortcuts when time is tight

Bonus points if you've worked on:

B2B SaaS or finance/ERP tools

BaaS APIs or payment infra

Serverless, AWS, event-driven architecture exposure

Our Stack:

Backend: Python / Flask / SQLAlchemy

Frontend: Typescript / Vue3 / Amplify

Data: PostgreSQL / DynamoDB / S3

Infra: AWS / Serverless / Docker / Airflow / Databricks

Tooling: Git / GitLab / Sentry
