Software Engineer 1 (Java / Kotlin) - Finance

About the job:

• Massive Scale: Design, build, and optimize systems that handle thousands of requests per minute. This is high-availability, high-performance engineering in practice.
• Modern Tech Stack: Work with a world-class, cloud-native environment. Our core technologies include Kotlin, Spring, Kafka, and Kubernetes. We're not shy when it comes to ML too :)
• True Ownership & Autonomy: We live by a "you build it, you run it" philosophy. You'll join an agile, autonomous team with full ownership of your microservices, from design to deployment.
• Complex Challenges: From distributed systems and data streaming to algorithmic optimization, you'll tackle the complex backend problems that power a massive, real-time marketplace.

In our department, we focus on online payments. We are building an ecosystem that enables secure, easy, fast, and convenient payments for buyers. We also take care of the seller's side, ensuring they can issue quick refunds or pay their Allegro billing. We provide a range of payment solutions, from bank transfers and BLIK to card payments, Apple Pay, Google Pay, installment products, and many others. In our team, we are directly responsible for integration with payment operators such as PayU and P24, and we cooperate with entities such as BLIK, Visa, and Mastercard.

If you want to find out which method buyers use most often, what their biggest problem is when paying, how to securely store payment card data, or how Apple Pay, Google Pay, and BLIK without a code work behind the scenes, join us.
