About the Role
Be responsible for developing and delivering backend services that power our mobile applications. As a core member of the mobile team, you’ll collaborate closely with iOS and Android engineers to ensure our APIs are mobile-first—designed for responsiveness, efficiency, and resilience in real-world network conditions. Your work will directly impact the performance and reliability of the mobile experience for our users.

- Participate in code reviews and contribute to the development of technical standards.
What We\'re Looking For
- 7+ years of experience in Java (Spring/Spring Boot/Spring Batch) development.
- Strong experience designing and implementing API services, including optimization for mobile clients—focused on expected response times, resilience to unstable or low-bandwidth connections, and efficient data handling to minimize consumption.
- Experience with swagger/OpenAPI to facilitate integration with mobile teams.
- Experience with relational databases (PostgreSQL), NoSQL databases (Redis), and data modeling.
- Experience with cloud platforms (AWS).
- Hands-on experience with secure API development using TLS, OAuth2, and enterprise-grade encryption methods
- Firm grasp of backend design principles, modularity, and maintainability
- Passion for solving complex problems and building systems that scale
- Experience with system design and the ability to architect scalable, high-availability solutions.
- Excellent analytical and problem-solving capabilities.
Nice to Have
- Previous experience in fintech or financial services
- Familiarity with AWS components (e.g., ECS, API Gateway, SQS, RDS, CloudWatch)
- Exposure to containerization and orchestration (Docker, Kubernetes)
- Understanding of enterprise data pipelines, messaging systems (Kafka, RabbitMQ)
- CI/CD tooling and DevOps best practices
Why Join Us
- Be a key player in shaping our core backend systems.
- Collaborate in a high-performance, remote-friendly environment.
