About The Position

Miratech is seeking a Senior Routing Engine Developer to design and build a next-generation interaction routing platform for enterprise contact center operations. The developer will create the core engine that intelligently distributes voice and digital interactions across agents, queues, skills, channels, and business units in real time. The position involves building scalable backend services that handle high volumes of routing decisions while meeting strict latency, availability, and resiliency requirements. The work primarily uses Java, Spring Boot, distributed architectures, event-driven systems, and cloud-native technologies, in collaboration with product, architecture, workforce management, telephony, and CX platform teams.

The role also includes translating business journeys and operational requirements into technical solution components and roadmaps; defining non-functional requirements; reviewing designs and code; managing technical risks; and establishing engineering standards, reusable patterns, quality gates, documentation expectations, and technology guidance. The position collaborates with CX domain experts and supports integrations with telephony, digital messaging, workforce management, CRM, identity, reporting, and analytics platforms.

Requirements

• At least 8 years of software engineering experience, including substantial ownership of architecture and technical delivery for distributed applications.
• Expert-level hands-on experience with Java and Spring Boot.
• Experience implementing distributed systems and microservices architectures, REST APIs, persistence, security, testing, and performance engineering.
• Experience developing routing logic for contact center, communications, or customer engagement platforms.
• Knowledge of ACD concepts, agent states, queue management, skill-based routing, priority routing, proficiency routing, and workload balancing.
• Experience building high-throughput, low-latency transaction processing systems.
• Deep understanding of API-first design, event-driven architecture, messaging, distributed systems, and cloud-native engineering.
• Experience with PostgreSQL or comparable relational databases, data modeling, integration data flows, and transactional design.
• Hands-on experience with contact center or CX platforms and the operational concepts behind customer routing and engagement.
• Excellent communication skills, including the ability to produce clear technical documentation and lead client-facing workshops.

Nice To Haves

• Experience with real-time communications platforms such as FreeSWITCH or Kamailio.
• Knowledge of optimization algorithms, decision engines, or scheduling systems.
• Experience with Genesys, NICE, Five9, Amazon Connect, Cisco, Avaya, or comparable contact center platforms.
• Exposure to workforce management processes and integrations involving forecasting, schedules, and adherence.
• Familiarity with Kafka or RabbitMQ, Kubernetes, Jenkins, observability platforms, API gateways, and security architecture.
• Practical experience with AI-assisted software development or AI-enabled solutions, including tools such as Claude or GitHub Copilot.

Responsibilities

• Design and develop enterprise-scale routing engines that distribute voice and digital interactions in real time.
• Implement intelligent routing algorithms based on skills, priorities, capacity, availability, and business rules.
• Ensure high availability, scalability, resilience, and performance across queues, routing paths, and interaction workloads.
• Design and maintain APIs for routing configuration, administration, monitoring, and integration.
• Optimize systems for high concurrency, fault tolerance, resiliency, and predictable performance.
• Integrate routing services with telephony, digital messaging, workforce management, CRM, identity, reporting, and analytics platforms.
• Design and develop critical Java and Spring Boot services, APIs, integration components, and reference implementations.
• Translate business journeys and operational requirements into solution components, interaction flows, deployment views, and technical roadmaps.
• Define non-functional requirements for availability, performance, concurrency, security, privacy, observability, disaster recovery, and supportability.
• Review designs and code, identify technical risks, challenge assumptions, and make pragmatic decisions balancing quality, time, and cost.
• Establish engineering standards, reusable patterns, quality gates, documentation expectations, and technology adoption guidance.
• Collaborate with CX domain experts to translate operational requirements into routing capabilities.

Benefits

• Comprehensive compensation and benefits package, including health insurance and a relocation program.
• Remote-work flexibility through a work-from-anywhere culture.
• Professional development opportunities, including certification programs, mentorship and talent investment programs, internal mobility, and internship opportunities.
• Inclusive and supportive multicultural work environment with open communication and regular team-building company social events.
