NCS is a leading technology services firm that operates across the Asia Pacific region in over 20 cities, providing consulting, digital services, technology solutions, and more. We believe in harnessing the power of technology to achieve extraordinary things, creating lasting value and impact for our communities, partners, and people. Our diverse workforce of 13,000 has delivered large-scale, mission-critical, and multi-platform projects for governments and enterprises in Singapore and the APAC region.

**Responsibilities**:
1. Technical Leadership in RAN Deployment and Site Integration
- Deploy RAN networks to provide coverage for outdoor, indoor, tunnel, and maritime environments.
- Provide solution for integrating the base station into the existing RF cabling network for in-building RF coverage and tunnel RF coverage.
- Integrating base stations with the Core Network and Transport Network, and troubleshoot interoperability issues.
- Performing base station software installation and firmware upgrades.
- Verifying alarms, resolving hardware/software and troubleshoot complex RAN layer 1/2/3 issues during integration.
- Analyze and mitigate RF interference to minimize signal degradation and ensure high-quality wireless communication services.

2. RAN Parameters Configuration
- Configure base station parameters based on the outputs from RF planning.
- Validate and adjust RF parameters (e.g., transmit power, PCI, neighbour lists) to ensure compliance with design specifications.
- Collaborate with RF teams to implement RF design parameters and resolve on-ground deployment challenges.

3. RF Performance Validation:

- Conducting site verification and ensuring compliance with design specifications.
Performing call tests, throughput tests, and handover tests.
- Use tools like spectrum analyzer or scanner data to identify and resolve RF-related issues (e.g., external
- interference, poor signal quality).

4. Presales and Solution Design
- Lead technical discussions with customers to understand RAN deployment requirements (LTE/5G, O-RAN).
- Size, scope, and estimate efforts for RAN projects (e.g., site counts, hardware/software needs, timelines).
- Develop high-level and low-level design (HLD/LLD) documents for RAN solutions.
Collaborate with sales teams to create winning proposals, BoQs (Bill of Quantities), and SOWs (Statements of Work).
- Liaise with Nokia, Ericsson, and O-RAN vendors to align on product capabilities, roadmaps, and integration requirements.

5. Emerging Technology Support:

- Assist in trials for 5G NR, O-RAN, or AI-RAN solutions, leveraging LTE expertise to support seamless evolution.
- Bachelor’s degree in Electrical Engineering, Telecommunications, or related field.
- 5 years of hands-on experience in LTE/5G RAN configuration, RF design implementation, or RAN operations.
- Proficiency with LTE/5G RAN equipment and RF planning tools for indoor or outdoor RF planning
- Solid understanding of RF engineering principles, wireless communication systems, and radio access network technologies.
- Strong knowledge of LTE/5G protocols and RF principles (propagation models, link budget analysis).
- Experience using RF repeaters in the design for coverage extension and a thorough understanding of RF repeater deploying requirements.
- Familiarity with drive test tools (e.g., NEMO or TEMS) for RF performance validation.
- Familiarity with VSWR, DTF VSWR, and passive intermodulation (PIM) testing.
