About the Role

We're seeking a Lead Software Architect with deep expertise in backend development and building scalable, high-performance systems. This role is perfect for someone who thrives in fast-paced, high-scale environments—where milliseconds matter—and can architect solutions capable of handling thousands of transactions per second with reliability and speed.

Key Responsibilities

• Architect and lead the design of scalable, high-availability microservices for payment and transaction systems.
• Collaborate with engineering leads and DevOps teams to implement containerized solutions using Kubernetes.
• Ensure robust performance in high-transaction environments, optimizing systems for speed and fault tolerance.
• Drive full-stack architectural decisions, balancing backend performance with seamless user experiences.
• Mentor development teams and enforce software engineering best practices.
• Partner with stakeholders across security, product, and infrastructure to align system architecture with business goals.

Technical Requirements

• 8+ years of backend development experience with deep expertise in Java (Spring Boot, JDK 11+).
• Proven track record of architecting and scaling systems in high-throughput environments (e.g., payment gateways, fintech, eCommerce).
• Strong experience with Kubernetes, containerization, and cloud- deployments (GCP, AWS, or Azure).
• Solid understanding of microservice architectures, service mesh, and event-driven systems.
• Familiarity with full-stack development—experience with modern front-end frameworks a plus.
• Expertise in scaling distributed systems, managing load balancing, caching, and redundancy.

Nice to Have

• Experience with PCI compliance or secure payment systems.
• Knowledge of real-time monitoring and observability tools (Prometheus, Grafana, ELK).
• Prior work in scale-up or startup environments.

Why Join Us

• Build mission-critical systems used by millions.
• Lead architectural decisions at a company scaling fast.
• Work with a passionate, collaborative, high-caliber engineering team.
