Lead Integrations Engineer

🚀 Lead Integrations Engineer | Fintech | Remote (Portugal)

One of the most exciting engineering opportunities I've worked on this year👀🙌

I'm partnering with an ambitious, AI-first fintech that's rethinking how money moves through modern payment infrastructure. They're looking for a Founding Lead Integrations Engineer to own one of the most business-critical areas of the platform.

This isn't another backend engineering role.

You'll be responsible for building the company's entire external API ecosystem from the ground up—creating seamless integrations for customers and partners, shaping the developer experience, and laying the technical foundations that will enable the business to scale globally.

If you love solving complex integration challenges and want genuine ownership from day one, this is one to look at.

What you'll bring:

• Public API & integrations expertise❗️
• Payments or fintech experience❗️
• Scalable API platform design❗️
• Event-driven architecture and distributed systems experience
• Strong backend engineering background

Why it's different:

✨ Founding engineering opportunity with real influence

✨ Build an API platform from scratch, not inherit one

✨ Work on technically challenging integration problems at scale

✨ AI-first engineering culture where automation is embedded into everything

✨ High ownership, fast decisions and the chance to shape the future of the platform

This is an opportunity to have a genuine impact on the architecture, engineering standards and developer experience of a product from its earliest stages!

If you're someone who's passionate about APIs, integrations and building products that other developers love to use, apply now!

💰65,000-90,000 (euros)
