Accountabilities:

Technical team leadership: Lead, mentor, and manage a team of approximately five engineers and QA specialists, overseeing sprint planning, task allocation, technical reviews, and delivery across multiple global rollout projects.
Engineering standards and processes: Establish engineering best practices, reusable integration templates, automated testing strategies, and standardized technical documentation and handover procedures.
Global operator integrations: Lead technical integrations with host mobile network operators across signalling, packet core, voice, and messaging systems.
Full MVNO architecture: Own the design, configuration, and implementation of core network components, including subscriber databases (HSS/HLR), packet core infrastructure, signalling routing, and messaging platforms.
Signalling and protocol management: Oversee implementation, integration, and troubleshooting across the signalling stack, including Diameter and SS7, ensuring reliable communication between network components.
End-to-end service readiness: Ensure the successful delivery of data, voice, and SMS services, covering session management, policy enforcement, data routing, VoLTE, legacy circuit-switched voice, and international interconnections.
Mobile number portability: Design and validate number portability routing solutions that comply with country-specific regulatory requirements and enable reliable call routing.
Regulatory compliance: Ensure compliance with telecommunications regulations in each market, including lawful interception requirements under ETSI ES 201 671 and TS 102 232, HI1/HI2/HI3 interfaces, and emergency service routing such as E112, 911, and 999.
Quality assurance and testing: Collaborate with QA specialists to define and execute integration test plans, stress tests, and acceptance testing, ensuring systems meet performance, reliability, and operational requirements.
Operational readiness and handover: Lead Operational Readiness Reviews and ensure newly deployed systems are thoroughly tested, documented, and transferred to the 24/7 operations team under the Build-to-Run model.
Continuous improvement: Identify opportunities to improve integration efficiency, automation, network reliability, and delivery processes across concurrent rollout initiatives.

Requirements

Mobile core experience: At least five years of hands-on experience working with mobile core networks, including the design, implementation, integration, or operation of telecommunications infrastructure.
Technical leadership: At least two years of experience leading engineers and/or QA specialists in an agile, project-based, or delivery-focused environment.
Packet and voice core expertise: Strong working knowledge of packet core and voice core technologies, including HSS/HLR subscriber databases, policy and charging systems, VoLTE, and legacy circuit-switched voice.
Signalling protocols: In-depth knowledge of Diameter, SS7, and SIP, with practical experience troubleshooting and integrating signalling systems.
Messaging architecture: Experience with SMS architecture, routing, and interworking with other mobile network operators.
MVNO integration: Understanding of Full MVNO architectures, host operator integrations, and the technical requirements for launching mobile services across multiple markets.
Regulatory knowledge: Familiarity with telecommunications compliance requirements, mobile number portability, lawful interception, and emergency service routing across different jurisdictions.
Delivery and project management: Proven ability to coordinate multiple concurrent rollout streams, prioritize technical work, and deliver complex integrations within agreed timelines.
Quality and operational readiness: Experience with integration testing, stress testing, acceptance testing, technical documentation, and structured handovers to operational teams.
Communication and collaboration: Strong communication skills, a collaborative mindset, and the ability to coordinate effectively with engineering, QA, and operations stakeholders in an international environment.
