Tech Lead – Core Network

This is a fully remote position, open to applicants in Spain.

📋 Description

• Take ownership of the technical design for Configuration Management functionalities within a multifaceted, multi-vendor Core Network setting, ensuring both scalability and resilience.

• Lead a delivery team: you establish the direction and evaluate design, while your team manages the daily platform coding tasks.

• Make and support technical decisions in discussions with the customer's Core Engineering team.

• Facilitate the conversion of operator change practices — including change windows, CMDB updates, and rollback expectations — into automated and auditable processes.

• Manage vendor and data-model interactions across Ericsson, Huawei, and other relevant vendors, encompassing YANG modules and NETCONF exports.

• Serve as the technical escalation point for the account, overseeing vendor interactions, lab access, and integration with the customer's change-management systems.

⛳️ Requirements

• Extensive experience in managing a Configuration Management tooling stack for mobile Core — such as Cisco NSO, HPE Service Director, Ericsson ENM, or a comparable in-house developed platform: including golden configurations, drift detection, and templating.

• Proven track record in managing configuration changes on live Core systems: encompassing change windows, governance, rollback strategies, post-change KPI validation, and the discipline required in 24x7 environments.

• Proficient understanding of NETCONF and YANG — you have directly executed get-config and edit-config against live nodes and can interpret schema deviations.

• Practical experience with at least one 5G SA Core (Ericsson, Nokia, or Huawei), along with a solid conceptual foundation across 5G SBA and 4G EPC architecture.

• Demonstrated experience leading a delivery team through customer-facing service delivery, integration, or first-of-a-kind deployments.

• Fluent in English; working proficiency in Spanish is highly desirable, as customer sessions are conducted in both languages.

🏝️ Benefits

• Competitive salary, health insurance, and a Flexible Compensation Plan as part of the enterprise benefits.

• Annual training budget to ensure you remain technologically updated and advance professionally.

• Flexible working hours: we understand that life extends beyond the workday; we offer flexibility in both start and end times.

• Additionally, we enjoy a shortened workday on Fridays and during the summer months (July and August).

• Our projects are at the forefront of technology and operate in both national and international contexts, allowing for global growth opportunities.

• We offer a flexible working model tailored to the needs of each role and team, with options ranging from remote to hybrid or office-based arrangements.

• Our employee satisfaction survey indicates that we foster a positive work environment filled with talented professionals.
