🧠 Who We’re Looking For

Are fluent in PHP or Java, and understand design patterns deeply

Have worked with payment providers (Visa, MasterCard, PayPal, MobilePay…)
Have a passion for Machine Learning
Come from an Agile/Scrum background and live by that mindset

🤝 Meet the Team
We’re a group of tech enthusiasts, problem-solvers, and collaborators. We take our work seriously — but not ourselves. Expect regular laughs, knowledge-sharing, and the occasional social event (yes, the dress code is casual – even at the party).
At AltaPay, diversity isn’t a buzzword — it’s our strength.
We celebrate differences, support inclusivity, and create space for everyone to thrive. No matter who you are, you’re welcome here.
