The Role
We're looking for a Backend Software Engineer (Java mainly) with hands-on AWS experience to join us. Whether you bring a few years of experience or are a seasoned engineer, what matters is that you write clean, well-tested Java code, understand distributed systems, and are comfortable owning services in production. You'll design, build, and operate backend services end to end - from architecture discussions to deployment and monitoring.
Tasks
What you'll do
- Design, develop, and maintain backend services in Java running on AWS.
- Build and optimize data processing and reporting pipelines handling large datasets.
- Work with AWS services such as S3, Athena, Lambda, SQS, Redshift, and RDS to build scalable, cost-efficient solutions.
- Own your services in production: monitoring, alerting, performance tuning, and incident response.
- Collaborate with product and other engineering teams across the tribe to deliver features that matter to merchants.
- Contribute to code reviews, technical design discussions, and the continuous improvement of our engineering practices.
Requirements
What you bring to the table
- Solid professional experience in Java backend development (Spring, Quarkus or similar frameworks).
- Hands-on experience building and running workloads on AWS.
- Good understanding of relational databases and SQL (PostgreSQL experience is a plus).
- Experience with distributed systems, message queues, or batch/stream data processing.
- A pragmatic approach: you value maintainability, testing, and shipping working software.
- You possess a fluent command of the English language.
- A university degree in Computer Science or a closely associated discipline is required.
Nice to have
- Experience with AWS analytics services (Athena, Glue, ETL).
- Familiarity with infrastructure as code (Terraform, CloudFormation).
- Background in payments, fintech, or other high-volume transactional domains.
