Senior Solution Architect - Core Networks

About the Role
At the company Engineering, we are shaping the future of mission-critical connectivity across the globe. Our Connectivity & Network Engineering teams are at the heart of next-generation telecom transformation, delivering resilient, secure, and scalable core network platforms for demanding environments. We are growing our team of senior technical leaders in Al-Khobar to own architecture decisions, drive multi-vendor integration, and lead high-performing engineering teams. If you are a seasoned core network architect who thrives at the intersection of technical depth and strategic leadership, this opportunity is for you.

We are looking for an exceptional Lead Core Network Architect to own architecture and technical leadership of mobile core networks for private mission-critical connectivity platforms. You will define end-to-end core architecture strategies, lead complex multi-vendor integrations, and serve as the principal technical authority across EPC, 5G Core, and IMS domains — ensuring every solution is resilient, scalable, and built to the highest standards of carrier-grade reliability.

Key Responsibilities
In this role, you will:

• Architect and own end-to-end mobile core network solutions across EPC, 5G Core, and IMS domains, ensuring carrier-grade resilience and scalability for mission-critical private network environments.
• Define comprehensive core network architecture strategies including capacity planning, redundancy models, and geo-resilience designs, translating complex SLA requirements into robust, future-proof technical solutions that meet the highest standards of availability and performance.
• Lead multi-vendor integration across RAN, transport, OSS, MCX, and security domains, managing technical interdependencies and ensuring seamless end-to-end interoperability across the full network stack in large-scale deployment programs.
• Produce high-quality High Level Design (HLD) and Low Level Design (LLD) documentation, operational runbooks, and technical reference architectures, ensuring all solutions are thoroughly documented and ready for operational handover.
• Drive vendor technical and relationship management, acting as the primary technical interface with key technology partners, evaluating vendor capabilities, influencing roadmaps, and ensuring alignment with program objectives and customer requirements.
• Lead customer engagement activities at a senior technical level, building trusted relationships with key stakeholders, presenting architectural recommendations with clarity and confidence, and translating complex technical concepts into business-aligned outcomes.
• Manage and mentor the core network engineering team, providing technical guidance, fostering a culture of engineering excellence, and developing the next generation of core network talent within the organization.
• Support deployment, performance optimization, and acceptance activities, providing hands-on technical leadership throughout the delivery lifecycle to ensure every solution meets design intent, performance benchmarks, and operational readiness criteria.

Your Profile
We are looking for a technically exceptional and strategically minded core network leader who brings deep domain expertise, proven delivery experience, and the gravitas to lead in complex, high-stakes environments. Candidates should have:

• 12+ years of experience in telecom core network architecture, with a strong and demonstrable background in mission-critical network environments and proven track record of leading large-scale, complex core network programs from architecture through to deployment.
• Deep technical expertise across EPC, 5G Core, and IMS technologies, including thorough knowledge of subscriber management, policy and charging systems, gateway functions, and the end-to-end mobile core architecture in both standalone and non-standalone 5G configurations.
• Extensive experience leading large-scale, multi-vendor core network deployments, with the ability to manage complex technical interdependencies, drive vendor alignment, and ensure seamless integration across RAN, transport, OSS, MCX, and security domains.
• Strong proficiency in IP networking, routing protocols, and security controls, with ability to design and validate transport and security architectures that underpin mission-critical core network platforms with uncompromising reliability.
• Demonstrated ability to translate SLA requirements into robust technical solutions, with experience producing HLD/LLD documentation, operational runbooks, and capacity and geo-resilience strategies for carrier-grade network environments.
• Proven senior stakeholder management and customer engagement skills, capable of building trusted relationships at executive level, influencing architectural decisions, and communicating complex technical strategies with clarity and authority.
• Strong leadership and team management capabilities, with experience building, guiding, and mentoring core network engineering teams in fast-paced, multicultural, and high-pressure delivery environments.
• Experience working in or with KSA-based telecom operators or service providers is highly advantageous, familiar with the regional deployment landscape, operational expectations, and strategic connectivity priorities aligned to Vision 2030.
