Staff Software Engineer

• Define and own the end-to-end architecture for SIP trunking, routing, and calling plan services.
• Establish routing strategies for Least Cost Routing (LCR), redundancy, and carrier optimization.
• Lead capacity planning and carrier interconnect design to support global scale.
• Drive adoption of best practices for SIP routing resiliency, failover, and codec optimization.

Hands-On Engineering, Automation & Microservices

• Actively contribute to the design, coding, and deployment of Spring Boot microservices for voice provisioning, routing management, and real-time monitoring.
• Develop and maintain REST API endpoints and workflows for SIP trunk onboarding, routing updates, and calling plan automation.
• Implement event-driven architecture (Kafka, RabbitMQ, etc.) to publish real-time call quality and operational events for analytics.
• Build automation scripts, pipelines, and integrations to reduce manual intervention in voice operations.

Voice Observability & Analytics

• Define key voice performance indicators (MOS, jitter, packet loss, call setup times) and ensure accurate telemetry collection.
• Develop analytics dashboards and data pipelines for internal operational teams and customers.
• Set standards for alerting, SLA reporting, and proactive incident detection.

Technical Leadership & Mentorship

• Serve as the technical authority for SIP routing, voice automation, and microservices design.
• Mentor engineers in voice architecture, coding best practices, and automation frameworks.
• Influence product and engineering roadmaps to ensure alignment with long-term platform goals.

Testing & Quality Standards

• Set testing and validation strategies for all voice-related services, including failover, routing logic, and interoperability.
• Code and maintain test automation using tools such as SIPp, custom scripts, and CI/CD integration.
• Drive continuous improvement in QA, monitoring, and deployment processes.

Required Skills & Experience

• 10+ years in telecommunications engineering, with extensive experience in SIP routing, SIP trunks, and global calling plans.
• Proven track record as a technical leader or architect in large-scale voice service deployments.
• Expert-level knowledge of SIP call flows, routing algorithms, and carrier interoperability.
• Strong hands-on experience with Spring Boot microservices, Java coding, and event-driven architectures.
• Proficiency in REST API design for telecom provisioning and automation.
• Deep understanding of telecom protocols (SIP, RTP, WebRTC) and media negotiation.
• Experience in voice analytics, metrics pipelines, and dashboard integration.
• Familiarity with testing and automation tools (SIPp, scripting in Python/Bash/Java).
• Strong coding, debugging, and performance optimization skills for real-time voice systems.
• Exceptional communication and stakeholder management skills, with the ability to influence technical direction at the organizational level.

Preferred Skills

• Experience with cloud-based voice platforms (e.g., Webex Calling, Broadsoft, Twilio, Zoom Phone, AWS Chime, Teams Direct Routing).
• Knowledge of CI/CD pipelines for telecom applications.
• Familiarity with cloud infrastructure (AWS, GCP, Azure) for hosting and scaling voice services.
• Understanding of security best practices in SIP and VoIP, including encryption, fraud prevention, and compliance requirements.
• Experience integrating voice automation workflows with OSS/BSS systems and customer portals.
