Key Responsibilities
This role primarily involves working as a Contact Centre/Telephony Engineer (70%), complemented by Linux/Automation Engineer duties (20%) and Technical Business Analyst/Stakeholder Support (10%). The candidate will manage and support enterprise contact center platforms, ensuring seamless operation within a 24x7 global environment. Responsibilities include troubleshooting SIP/VoIP networking issues, handling production incidents and escalations, and supporting contact center modernization or migration initiatives. The role demands hands-on Linux administration, basic to intermediate Python automation, and effective collaboration across multiple time zones. Clear communication skills are essential for translating technical details to non-technical stakeholders and ensuring smooth shift handovers.

Required Qualifications
Candidates should have a minimum of 3 years of hands-on experience with enterprise contact center platforms such as Genesys, NICE, Five9, Avaya, Cisco, or similar. A strong understanding of SIP, RTP, and VoIP fundamentals in a multi-region enterprise setting is essential, along with demonstrated expertise in troubleshooting call flows, routing logic, and media path issues. Solid networking knowledge—including TCP/IP, DNS, routing, firewalls, and QoS—is required. Experience with open-source telephony components like FreeSWITCH, Kamailio, OpenSIPS, or Asterisk is critical, as is prior involvement in contact center platform migrations or replacements.

Proficiency in SIP debugging tools such as sngrep, sipgrep, Wireshark, and HOMER is expected. Candidates must be skilled in Linux service configuration, log analysis, and command-line troubleshooting. Programming or scripting experience in at least one language (Python, JavaScript, Bash, or equivalent) is necessary. Familiarity with system integration via REST APIs and webhooks, Git version control, and deployment workflows is also required. Knowledge of Infrastructure as Code tools like Terraform or Ansible, along with monitoring and observability platforms such as Splunk, Grafana, Prometheus, or Datadog, is important. Additional competencies include SQL and relational database fundamentals, automated voice testing platforms (e.g., Cyara), and awareness of AI-assisted contact center technologies like virtual agents, intent-based routing, and speech analytics.

Preferred Qualifications and Benefits
Familiarity with telecom regulatory requirements, including call recording consent and data residency, is advantageous. Experience or knowledge of ITIL/ITSM frameworks is also preferred. The role offers the opportunity to be part of a forward-thinking organization committed to continuous reinvention and digital transformation. Wipro fosters a culture where employees are encouraged to evolve their skills and careers alongside the changing industry landscape, empowering them to shape their professional journey.

This position is available in multiple locations including Hyderabad, Chennai, Bangalore, Pune, Mumbai, and Bhubaneswar. Candidates should be prepared to work in a dynamic environment that demands sound judgment in escalation management, the ability to prioritize under pressure, and effective stakeholder engagement across regions.
