Backend Data Engineer - Java/Scala

Our team is building the settlement and cash processing systems that drive how cash from our customers is processed and accounted for - enabling reliable, scalable financial operations across every market, product line, and partner. Our systems are essential to our stakeholders' ability to track and report revenue and taxes, supporting all of our core business lines.

As engineers on this team, we design and maintain the backend and data platform capabilities that power millions of transactions each day with precision. We build services that handle settlement and bank transactions, produce compliant financial records, and support regulatory requirements across global markets - all while staying agile to keep up with our evolving business model and staying in sync with our many payment partners. We build robust services that provide clarity over what's happening under the hood of millions of daily transactions, enabling quick action to any disruption. Our modular, process-oriented components simplify the development, maintenance, and scaling of the critical Order to Cash enterprise process that underpin the financial operations.

We are starting two major initiatives: a revamp of our historical settlement system in order to align with our modularity strategy as well as expanding into the adjacent domain of payment fees, which is a massive cost center in need of good data for analytics in order to optimize the space. We're looking for engineers passionate about building complex, high-impact systems. You'll work closely with stakeholders in Finance (Accounting and Payments), Product, and Engineering to design solutions that are scalable, auditable, and robust. If you're energized by the challenge of transforming intricate business processes into clean, extensible platforms we'd love to have you on the team.

What You'll Do

- Gain deep expertise in client's revenue and settlement systems, understanding how it enables financial operations, compliance, and strategic decision-making across the company.

- Design and implement scalable backend and data systems that process millions of transactions daily to enable the cash-application process and financial reporting.

- Build intuitive, self-serve tools that empower Finance teams to define and manage product-specific revenue and settlement configuration independently, without requiring engineering involvement.

- Develop and enhance modular platform capabilities that encodes critical enterprise workflows, promoting consistency, reusability, and ease of maintenance across financial systems.

- Partner closely with Engineers, Product and Finance stakeholders to design systems that are scalable, auditable, and highly reliable.

- Champion engineering best practices, strong architectural design, and operational excellence across backend and data platforms.

- Foster a collaborative team culture rooted in shared ownership, constructive feedback, and continuous improvement.

Who You Are

- You possess a T-shaped engineering skill set - deep expertise in either data or backend engineering (Java), while growing the ability to work effectively across both. For this role, experience or familiarity with processing large-scale transactional and financial data, using batch/streaming frameworks like Spark, Flink, or Beam (with Scala for data engineering), and building scalable backend systems in Java is a strong advantage.

- You possess a foundational understanding of system design, data structures, and algorithms, coupled with a strong desire to learn quickly, embrace feedback, and continuously improve your technical skills.

- You're familiar with cloud-native development and deployment, ideally within the Google Cloud Platform.

- You think critically about system design and strive to build solutions that are reliable, maintainable, and auditable at scale.

- You have good communication skills and can articulate your ideas and ask clarifying questions.

- You love collaborating with others.

- You thrive in ambiguous and fast-changing environments, and know how to make progress even when requirements are evolving.

- You approach platform engineering with empathy for your users - prioritizing usability, configurability, and long-term sustainability.

- You care deeply about code quality, testing, and documentation, and you aim to build systems that are easy to understand and operate.

- You enjoy collaborating across functions and bring clarity and alignment when working with engineering, finance, and product partners.

- You're naturally curious, self-motivated, and always looking for ways to grow your technical skills and improve how things are done.
