About Your Team

The position is part of the Enterprise Network & Multimedia Services (ENS) group within the Enterprise Infrastructure Services (EIS) division. EIS delivers secure, reliable, and globally accessible IT infrastructure across both on‑premises and cloud environments to support Fidelity’s applications, digital services, and dynamic working models.

ENS plays a critical role in delivering secure, scalable, and innovative network solutions that power global enterprise operations. We are a global team of 70+ professionals across the UK, Europe, India, and APAC. Historically organized by functions such as Operations, Delivery, and Engineering, ENS has evolved to embrace modern cloud technologies and Infrastructure‑as‑Code. To strengthen accountability, agility, and technical excellence, we are transitioning to an accountability‑based structure effective Q1 2026. Under this model, the team will be organized into seven technical service groups, each led by a manager who serves as both a people leader and the accountable owner for their services. These groups include Network Engineering (this role is the leader of this group), Core Network, Network Security, Traffic Gateway, End User Connectivity, Multimedia, and Common Services.

ENS is responsible for delivering consistent, secure, and compliant network and multimedia capabilities across the enterprise. Our services span a broad range of critical infrastructure, including SD‑WAN, campus and data center networking, firewalls, proxy, internet/extranet connectivity, and meeting collaboration solutions. The team is currently driving major technology transformations, including migrating from on‑premises infrastructure to cloud‑based solutions and implementing advanced network segmentation to align with the Digital Operational Resilience Act (DORA). These initiatives strengthen security, resilience, and agility in a rapidly evolving technology landscape.

Within ENS, the Network Engineering team serves as a senior technical authority, responsible for defining technical standards, shaping architecture, and driving complex solution design across multiple product groups. The team focuses on governance and innovation, including evaluating emerging technologies and ensuring consistent implementation of best practices. Comprising approximately 6 –12 highly experienced professionals, Network Engineering works closely with both internal and external stakeholders. This includes collaboration with Enterprise Architecture, IT Security, Business Application Support, and Technology Resilience teams, as well as ENS product groups and product owners. Together, the team ensures that ENS solutions are robust, compliant, and aligned with enterprise-wide architecture and regulatory standards.

About Your Role

As a senior technical leader, you will play a pivotal role in shaping ENS’s technology direction and ensuring architectural consistency across a diverse set of network and multimedia services. You will define and enforce technical standards, guide solution design for complex multi‑domain initiatives, and act as the primary governance authority for engineering practices within ENS. Your leadership will directly influence how global network services evolve to meet the demands of cloud adoption, regulatory compliance, and enterprise resilience.

In addition to technical governance, this role requires strong collaboration and stakeholder engagement. You will work closely with Enterprise Architecture, IT Security, Business Application Support, and Technology Resilience teams, as well as ENS Product Groups and product owners, to deliver integrated solutions that align with enterprise‑wide architecture and compliance frameworks. You will also contribute to ENS product roadmaps, ensuring technical direction, investment priorities, and operational readiness are coherently planned and delivered.

About You

As a senior technical manager, you are expected to bring extensive experience in enterprise network architecture and engineering, with a proven record of leading large-scale, multi-domain migrations and delivering complex transformation programs in highly regulated environments, ideally within financial services. The role expects the ability to interpret business requirements and translate them into actionable architectures, processes, and technical designs. This includes shaping both high-level and low-level designs, establishing standards and models across the full design-to-deployment lifecycle, and ensuring that solutions balance functionality with resilience, security, and operational efficiency. Comfort with evaluating new technologies and turning business problems into measurable, outcome-driven engineering solutions is essential.

You are expected to demonstrate deep technical expertise across enterprise networking domains, including routing, switching, data center fabrics, load balancing, network security, Zero Trust, identity-based segmentation, observability, and automation-driven operations. Strong knowledge of cloud networking, AI-assisted operations, DevOps-aligned engineering practices, and regulatory frameworks such as the Digital Operational Resilience Act (DORA) is required. The role further expects proven leadership in coaching engineers, running architecture and design authority forums, managing vendors, and handling senior-level technical escalations. Professional certifications such as CCIE or CCNP, PCNSE, CISSP, TOGAF, or cloud certifications from AWS or Azure are highly desirable.
