We're looking for a Senior Core Network
Engineer with strong Configuration Management expertise to take on a technical
leadership role in one of the most ambitious Core Network programmes in Europe,
working directly with one of the continent's leading telecommunications
operators.
This is a hands-on leadership position
within a small, high-impact team. You'll set the technical direction, defend
your decisions in front of demanding stakeholders, and lead a squad that counts
on you to have their back. If you enjoy environments where your judgement
carries weight and your decisions actually ship, this role is built for you.
What you'll do
· Own the technical design of Configuration Management capabilities
within a complex, multi-vendor Core Network environment, ensuring scalability
and resilience.
· Lead a delivery squad: you set direction and review design, while
your team handles day-to-day platform coding.
· Make and defend technical decisions in front of the customer's Core
Engineering team.
· Drive the translation of operator change practices — change windows,
CMDB updates, rollback expectations — into automated, auditable gates.
· Own vendor and data-model engagement across Ericsson, Huawei and
other in-scope vendors, including YANG modules and NETCONF exports.
· Be the technical escalation point for the account, from vendor
engagement to lab access and integration with the customer's change-management
systems.
Requirements
· A real track record managing configuration change on live Core:
change windows, governance, rollback strategy, post-change KPI validation, and
the discipline that 24x7 environments demand.
· Working fluency with NETCONF and YANG — you've personally run
get-config and edit-config against live nodes and know how to read a schema
deviation.
· Hands-on experience with at least one 5G SA Core (Ericsson, Nokia or
Huawei), plus solid conceptual grounding across 5G SBA and 4G EPC architecture.
· A track record leading a delivery squad through a customer-facing
service delivery, integration or first-of-kind deployment.
· Fluent English; working Spanish is a strong plus, as customer
sessions run in both languages.
None of this is mandatory on day one; a
strong Core lead will pick it up quickly working alongside our platform team.
· GitOps operations and the YANG toolchain (libyang, pyang, yangdiff
or similar).
· Reading-level Python and Kubernetes literacy — enough to review pull
requests and pair with engineers on tricky paths.
· Multi-element orchestration experience (Cisco NSO or HPE Service
Director).
· 3GPP interface familiarity, prior tenure at a Tier-1 European
operator, VoLTE/IMS exposure, or contribution to IETF/3GPP/ETSI standards work.
Benefits
· Competitive salary, health insurance and Flexible Compensation Plan as an enterprise benefit
· Annual training budget to help you stay
technologically up to date and grow professionally
· Time flexibility: our life is not just a
working day; we give you flexibility both in entry and exit. In addition, we enjoy
a reduced working day on Fridays and Summer (July and August)
· Our projects are cutting-edge in technology and are in both national
and international environments, making your growth global
· We provide a flexible working model, adapted to the needs of
each role and team, with options from remote to hybrid or office-based
arrangements.
· Our employee satisfaction survey tells us that we have a
great work environment and great professionals in the company. Do you want to
check it? Join us!
