Senior Java AWS Developer

Cynet Systems•San Antonio, TX

About The Position

This role is for a senior engineering leader responsible for designing, building, and delivering cloud-native, microservices-based platforms within a financial services environment. The position combines deep expertise in Java Spring Boot, GoLang, and AWS cloud infrastructure, with strong ownership across the full lifecycle—from architecture to production operations. The primary focus is on leading the development of scalable, secure, and resilient systems using modern microservices architecture. The lead will define architectural patterns such as API-first design, event-driven systems, and domain-driven design, ensuring alignment with enterprise standards and banking regulations. A key part of the role is building high-performance backend services using Spring Boot, while leveraging GoLang for optimized, low-latency services in critical components. On the cloud front, the role requires strong hands-on experience with AWS services and the ability to define and manage infrastructure using Terraform (Infrastructure as Code). This includes establishing best practices for automated provisioning, deployment pipelines, and environment consistency. The lead will also oversee DevOps practices, including CI/CD pipelines, containerization (Docker/Kubernetes), and observability using monitoring tools. From a delivery perspective, the role involves end-to-end ownership of full-stack engineering outcomes, particularly backend and API layers, while collaborating closely with frontend teams. The candidate must ensure seamless integration across systems and secure communication with downstream banking platforms. Given the financial services context, the role demands strong awareness of compliance, security, and regulatory requirements. The lead must design solutions that meet data privacy standards, ensure high availability, and support mission-critical functions such as payments, fraud detection, or core banking systems. Performance engineering is also critical, with emphasis on optimizing throughput, reducing latency, and implementing resilience patterns. In addition to technical leadership, the role requires managing distributed teams across onsite and offshore locations. The lead will mentor engineers, enforce engineering best practices, and drive governance around code quality, secure coding, and delivery standards. Strong communication skills are essential to engage with business stakeholders and translate requirements into scalable technical solutions. Overall, this role is suited for a senior professional who can bridge architecture, engineering execution, and business outcomes, delivering high-quality, compliant, and scalable platforms in a complex enterprise environment.
