Required Skills:
We are seeking a strong Senior Java Developer to design, build, and scale enterprise-grade distributed software solutions. In this role, you will tackle complex architectural challenges, developing highly scalable backend systems that power VOIP-based call processing, CTI, intelligent call routing, and compliance recording systems. You will act as a technical leader, mentoring junior developers and actively shaping our technology strategy to drive business value through modern engineering practices.
**What You Will Do**:
**Architecture & Development**
- Design, build, and optimize robust distributed microservice applications to ensure highly scalable backend performance.
- Develop, implement, and maintain both RESTful and GraphQL services to support complex business capabilities and high-volume data querying.
- Analyze, revise, and document challenges in existing system logic to continuously improve system reliability and reduce technical debt.
- Provide technical direction and execute strategic decisions encompassing information architecture, software design, analytics, and instrumentation.
**Technical Leadership & Collaboration**
- Mentor and guide team members, participate in code reviews, and foster a culture of high performance, continuous learning, and technical excellence.
- Collaborate with leadership and key stakeholders to define technology strategy, standards, and roadmaps, effectively addressing gaps between functional goals and existing capabilities.
- Drive technical decisions on software development projects, estimate project scope, and create comprehensive documentation.
- Partner seamlessly across technical disciplines, including web and mobile app development, to ensure cohesive service integration.
**Engineering Excellence**
- Champion AI-assisted coding workflows and automation techniques to efficiently divide large problem statements and enforce structural architecture practices.
- Adhere to and advocate for best practices in code development, version control, continuous integration/delivery, and test/build automation.
**What You Bring**
- Bachelor's degree (or foreign equivalent) in Computer Science, Information Technology, or Engineering.
- 8+ years of strong, hands-on programming experience, including deep expertise in Java, Spring Framework, and Springboot.
- Proven track record of designing, developing, and managing distributed microservice architectures.
- Strong hands-on experience designing API ecosystems (RESTful and GraphQL) and event-driven architectures using messaging systems like NATS.IO and Apache Kafka.
- Solid practical experience with concurrency and multi-threading to optimize application performance and responsiveness.
- 5+ years of experience utilizing containerization and orchestration technologies, including Docker, Kubernetes, and ArgoCD, for deploying web services into clusters.
- Exceptional problem-solving skills and the ability to apply established software design patterns to complex engineering challenges.
- Demonstrated ability to integrate AI coding workflows to streamline development (proficiency in modern development environments such as Kiro IDE is highly preferred).
- Experience in business process management and decision models, including Camunda BPMN.
**Nice to Have**:
- Experience with IVR technologies (including voice-to-XML conversion technology, VXML, CCXML, SCXML, and the RIVR framework) to create and optimize effective IVR systems.
