The Support Engineer - Retail Business (Udoy) role at ADN Telecom Limited involves managing technical operations for internet and telecom services. You’ll work closely with field teams, customers, and internal departments to ensure smooth network performance. This includes troubleshooting issues, configuring equipment, and maintaining documentation. The position requires a balance of hands-on technical skills and customer interaction, with a focus on resolving problems efficiently in a dynamic environment.
• Proficiency with GPON/EPON platforms like VSOL, BDCOM, C-DATA, and Huawei OLTs is essential.
• Strong understanding of VLAN configuration, PPPoE, DHCP, and IP addressing to handle network setup and customer needs.
• Ability to troubleshoot optical issues such as signal loss, fiber cuts, and attenuation using tools like OTDR and VFL.
• Experience in FTTH deployment, including planning split ratios, optical budgets, and ODN designs.
• Familiarity with monitoring systems for ONU status and traffic, along with coordination with NOC/BNG teams.
• Excellent communication skills to translate customer requirements into technical solutions and manage support tickets.
Candidates should highlight practical experience in telecom or ISP environments, particularly in Bangladesh. Local projects involving network maintenance, field support, or compliance with regional standards will strengthen your profile. Exposure to NGOs or INGOs that use similar technologies may also be advantageous. Focus on roles that involved troubleshooting, documentation, or vendor coordination, as these align with the job’s demands.
Education should reflect a BSc in Computer Science or a Diploma in Computer. Certifications in network engineering or vendor-specific training (e.g., Huawei, BDCOM) are highly recommended. Present these qualifications clearly in your resume, emphasizing how they relate to the job’s technical requirements. For example, include any training in VLAN tagging or OSPF/BGP protocols if applicable.
Knowledge of tools like OTDR, OPM, and VFL is critical for fiber testing, while familiarity with monitoring systems and ticketing platforms will aid in daily tasks. Practical use of these tools in real-world scenarios—such as diagnosing signal issues or tracking ONU inventory—will make your application stand out. Avoid listing theoretical knowledge; instead, focus on how you’ve applied these tools to solve problems.
For interviews, prepare to discuss specific projects or challenges you’ve faced, such as resolving LOS/LOF issues or configuring QoS settings. Bangladesh employers often value honesty and clarity, so be ready to explain your experience with concrete examples. Practice answering questions about customer communication, SLA management, and teamwork. Highlight your ability to work independently and stay organized under pressure.
