  • Proficient in Mongo, Spring and microservice-based architecture.
  • Proven experience with low-latency, high-throughput applications (sub-millisecond response times a plus).
  • Hands-on experience deploying applications on Red Hat OpenShift and/or Kubernetes.
  • Strong cloud experience with AWS services such as ECS, EKS, Lambda, S3, etc.
  • Strong communication skills and a bias toward action and opinionated design decisions.
Nice to Have
  • Familiarity with messaging systems (Kafka, RabbitMQ, etc.)
  • Prior experience in Payments Processing, financial services, or banking systems.
  • Exposure to container security and performance tuning on OpenShift.
  • Knowledge of payment gateways, ISO 20022, or SWIFT formats.
  • Collaborative, fast-paced, and engineering-driven culture.
  • Emphasis on engineering autonomy, architectural decision-making, and clean code
