What You’ll Do

As part of our Daily Banking area, you will join one of the 4 Deposits squads, a high-performance team of 5-6 engineers (including a Staff Engineer, Seniors, and Mid-level devs). We are responsible for the core engine that handles deposit accounts, meaning you will work on mission-critical features where performance, precision, and scalability are paramount.

We value freedom to implement and high autonomy. While we have a structured onboarding process, including a dedicated buddy and a month of deep-dive exercises into our business logic, we expect you to bring a proactive mindset from day one.

You Will

• Build and maintain scalable Java applications focused on complex financial calculations and high-performance deposit processing.
• Don’t just implement tasks; take initiative. Identify architectural bottlenecks and propose modern, resilient solutions.
• Translate business requirements into robust technical designs, working closely with your squad to ensure high-quality delivery.
• Conduct rigorous code reviews and champion best practices in TDD and automated testing.
• Debug complex issues and participate in on-call rotations to ensure the reliability of our global lending and deposit platform.

What You’ll Bring

• 5+ years (minimum 3 professional) of experience in Java development, with a deep understanding of the ecosystem.
• Proven ability to design scalable, resilient systems. You don’t just write code; you think about how it fits into the entire ecosystem.
• Strong experience with JUnit, Mockito, and TDD. You believe that a feature isn't "done" until it's fully tested.
• Solid experience with MySQL or other relational databases, specifically focused on performance tuning for high-volume transactions.
• High level of initiative and adaptability. You are comfortable working independently and mentoring mid-level engineers.

What You’ll Get

Join us to shape the future of banking, where your professional growth is equally as valued as your personal well-being.
