Upflow is hiring a Senior Full Stack Engineer

About the Role

As a Senior Full Stack Engineer, you'll play a central role in building and refining core product functionality from concept to deployment. You’ll work across the full stack to deliver reliable, scalable solutions that directly impact how customers interact with the platform.

What You’ll Do

  • Design and implement end-to-end features that solve real business and user challenges
  • Work closely with product and design to shape technical direction and execution
  • Write clean, testable code and deploy updates daily in a continuous delivery environment
  • Review code with a focus on clarity, maintainability, and long-term scalability
  • Diagnose and resolve performance bottlenecks and complex system issues
  • Contribute to engineering standards and help evolve development practices
  • Stay engaged with emerging tools and frameworks, integrating them where they add value

What We’re Looking For

  • At least five years of hands-on software development experience
  • Strong command of TypeScript, React, and SQL
  • A commitment to writing simple, well-tested code
  • Ability to balance speed and quality when prioritizing tasks
  • Comfort giving and receiving direct, constructive feedback
  • Fluency in English and strong communication skills
  • Preference for working in or near the Paris time zone, with availability for hybrid collaboration in Paris

Environment & Culture

The team values pragmatism, ownership, and continuous learning. You’ll work in an autonomous environment where initiative is expected and decisions are made close to the work. Leadership trusts engineers to own outcomes, not just tasks.

We emphasize growth—both technical and personal—with support for developing hard and soft skills. The culture is inclusive, transparent, and built on mutual respect. You’ll have access to top-tier tools, flexible work arrangements, and opportunities to connect with the broader tech community through offsites and events.

Compensation & Benefits

  • Salary range: €60,000 – €90,000 per year
  • Equity package aligned with impact and tenure
  • 35 paid days off annually
  • Comprehensive health coverage and meal vouchers
  • High-end equipment and modern office space in Paris
  • Support for professional development and learning
  • Hybrid work model with flexibility and team gatherings
  • Regular team offsites and participation in tech meetups

Our Commitment to Inclusion

We believe diverse perspectives strengthen our product and our team. Even if you don’t match every listed qualification, we encourage you to apply if you’re passionate about the work and believe you can contribute. We evaluate candidates broadly and value potential as much as proven experience.

About company
Upflow
Upflow builds the reference cash collection platform to help B2B companies get paid faster, more predictably, and with stronger customer relationships. Today, the order-to-cash process is mission critical for businesses, yet it remains fragmented across tools, teams, and workflows. Collections, payments, and reconciliation are often manual, reactive, and disconnected from the rest of the business. Upflow brings this entire process into one system — combining data, agentic automation, collaboration, and financial services to turn receivables into a predictable and scalable engine. We serve 500+ companies across 30+ countries, including Vercel, Lattice, Productboard, and are backed by leading investors including Y Combinator, Hedosophia, Hexa, and Lorimer. With teams across the US and Europe, we’re building a category-defining company at the intersection of finance, payments, and AI.
