About The Position

Miratech is seeking a Senior Routing Engine Developer to design and build an enterprise-scale interaction routing platform for contact center operations. The developer will build the core engine that distributes voice and digital interactions across agents, queues, skills, channels, and business units in real time, along with scalable backend services that process high volumes of routing decisions under strict latency, availability, and resiliency requirements.

The role works primarily with Java, Spring Boot, distributed architectures, event-driven systems, and cloud-native technologies. It involves collaboration with product, architecture, workforce management, telephony, CX platform teams, and CX domain experts to translate operational and business requirements into routing capabilities and technical solutions. The position also contributes to technical standards, solution design, risk assessment, and client-facing workshops.

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 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.
• Produce clear technical documentation and lead client-facing workshops.

Benefits

• Comprehensive compensation and benefits package, including health insurance.
• Relocation program.
• Remote-work flexibility.
• Professional development opportunities, including certification programs, mentorship and talent investment programs, and internal mobility.
• Internship opportunities.
• Inclusive and supportive work environment with open communication and regular team-building company social events.
