🌍 Join the Payment Revolution

Imagine this: Right now, hundreds of millions of talented entrepreneurs across the globe are building amazing businesses - AI startups, gaming companies, digital agencies. But there's a problem. An African developer creating the next big SaaS can't easily get paid by US customers. An Argentinian agency struggles to work with European clients. A Brazilian e-commerce store can't expand globally.

The result? $100+ billion in lost opportunities every year. The future economic powerhouses of the world are being held back by outdated payment systems built by boomers, for boomers.

We're changing that.

🚀 The Opportunity

At Inflowpay, we're not just building another payment processor. We're creating the financial infrastructure for tomorrow's economy - where a brilliant developer in Sao Paulo can seamlessly serve clients in Silicon Valley, Tokyo, or anywhere else.

Our mission is simple: ANY business from ANYWHERE should be able to sell to ANYONE. No borders. No barriers. Just pure opportunity.

💰 What We've Achieved

  • Raised $1.1M just months after launch from prestigious investors (including unicorn founders)
  • Strong client demand from day one
  • Building something that will impact millions of entrepreneurs worldwide

Job Description

As a Experienced Software Engineer at Inflowpay, you'll be at the forefront of building next-generation payment infrastructure that enables global commerce for emerging markets. You'll work directly with our founding team to architect, develop, and scale systems that process millions in transactions and serve businesses worldwide.

Preferred Experience

We're looking for a senior React/TypeScript/Node.js engineer who embodies both technical excellence and startup DNA.

Technical Excellence

  • Years of experience with TypeScript/Node.js and React
  • Strong understanding of backend architecture, APIs, and databases (PostgreSQL)
  • Experience with cloud platforms (AWS) and modern development practices
  • Bonus: Previous fintech or payment systems experience

Startup DNA

  • High ownership mentality : You don't just code, you think about the business impact
  • Thrives in uncertainty : You're energized by fast-changing priorities and ambiguous requirements
  • Move fast, break things : You ship quickly, iterate based on feedback, and aren't afraid of making mistakes
  • Excellence-driven : You have high standards for yourself and push others to be better
  • Bonus : Previous High Level (semi-professional/professional) Athlete

Cultural Fit

  • Direct communicator : You speak up when something isn't working and propose solutions
  • Globally minded : You understand we're building for entrepreneurs worldwide, especially emerging markets
  • Mission-driven : You genuinely care about democratizing access to global commerce
  • Resilient : Startup life is intense; lots of work, fast decisions, high stakes ; you need to handle pressure and bounce back from setbacks

Red Flags

  • Needs constant direction or hand-holding
  • Prefers stable, predictable environments
  • Only cares about the paycheck, not the mission
  • Can't handle constructive feedback or fast iteration

We're a small team where everyone has massive impact. If you want to build something that changes millions of lives while working with exceptional people, you're our person.
