SES S.A Brazil
Senior Engineer, 5G Core Network (Signaling), IRIS2
SES S.A Brazil, Germantown, Ohio, United States
Overview
Senior Engineer, 5G Core Network (Signaling), IRIS2 Requisition Number: 19294 Contract Type: Permanent Location(s): Betzdorf, LU ProgramME Description IRIS2 is the new European Union secure satellite constellation. This project is the European Union's answer to the pressing challenges of tomorrow to provide secure connectivity services and enhanced communication capacities to the EU and its Member States as well as to governmental users, private companies and European citizens while ensuring high-speed internet broadband to cope with connectivity dead zones. SES – together with other consortium partners and core members - was selected by European Commission to build and to operate the IRIS2 multi-orbit satellite constellation. The IRIS2 team enters next project phases and there is a strong need of support for all the activities around service provisioning and products that the system can offer in the future. The Senior Engineer, 5G Core Network (Signaling) is responsible for defining and implementing system concepts for 3GPP-based architectures, with a strong focus on
5G Core signaling protocols, control plane functions, and network orchestration . The role includes designing OSS functions, resource orchestration subsystems, and control/monitoring interfaces across terrestrial and non-terrestrial (NTN) environments. You will be part of an agile project organization where a flexible way of working and an adaptive mindset is required. PRIMARY RESPONSIBILITIES / KEY RESULT AREAS Define and specify
5G Core signaling requirements
(e.g., NAS, N1/N2/N3/N4 interfaces, SBI-based service communication, etc.) for both terrestrial and non-terrestrial networks. Define the
satellite constellation resource control signaling functions
for multi-orbit satellite systems. Design and specify
OSS orchestration and management signaling flows
for a multi-orbit satellite system. Define and manage the
implementation and testing of 5G-NTN signaling procedures
(e.g., registration, mobility management, session management). Provide system architecture input on
resource orchestration, service provisioning, and interworking signaling
between NTN and terrestrial 5G Core networks. Collaborate with stakeholders to define network requirements and ensure alignment with organizational objectives Generate and report identified risks in the form of risk registers Competencies
Ability to work independently and with limited supervision in complex environments, e.g. project or matrix organizations Flexibility and adaptability in response to changing project requirements and environments Ability to think strategically and align project goals with organizational objectives Problem-solving and decision-making abilities Effective communication skills, both written and verbal Ability to acquire detailed technical information within pre-defined deadlines and apply it in everyday situations. Strong analytical and problem-solving skills Ability to integrate into and lead cross-functional, multicultural and/or virtual project teams Proven communication skills to communicate complex information, concepts, or ideas in a confident and well-organised manner through verbal, written, and/or visual means. This also includes presentations in front of a larger audience, e.g. at conferences. Business-oriented and business proactive towards potential and/or current customers Innovative spirit, proactive approach towards new technical solutions Sense of initiative and a can-do attitude Ability to work independently with minimal supervision and in a team Qualifications, Background and Experience
Qualification Basis Master’s degree in engineering or science, preferably in Telecommunications Engineering. Expert knowledge of
3GPP 5G Core standards , especially
control plane and signaling protocols
(SBI/HTTP2, Diameter, NGAP, NAS, PFCP, SCTP). Proven experience implementing 3GPP Core Network subsystems, with emphasis on
signaling, resource allocation, and service orchestration . Experience in the telecom industry required; for Senior Engineer,
10+ years of relevant industry experience
is required. Hands-on experience with the
development, integration, and testing of 3GPP 5G Core signaling systems . Strong knowledge of
5G Core control plane functions : AMF, SMF, PCF, NRF, NSSF, UDM, AUSF. Experience with
network resource orchestration and signaling for 5G network slicing . Software implementation experience in telecom signaling contexts (protocol stacks, control plane frameworks). Basic familiarity with
5G-NTN signaling aspects , including access stratum (AS) and non-access stratum (NAS) adaptations for satellite links. Highly desirable experience (several of the following): Experience with satellite communications signaling and NTN integration. Knowledge of 5G-NTN signaling enhancements (Rel-17 and beyond, NR-NTN). Experience with telecom signaling protocol testing, troubleshooting, and simulation tools (e.g., Spirent, Keysight, Wireshark, dsTest). Experience with end-to-end signaling call flows for 5G attach, registration, session management, and mobility across NTN. Other key requirements / comments
Willing to work at least 60% onsite from office Travel as required for project realization purposes SES and its Affiliated Companies are committed to providing fair and equal employment opportunities to all. We are an Equal Opportunity employer and will consider all qualified applicants for employment without regard to race, color, religion, gender, pregnancy, sex, sexual orientation, gender identity, national origin, age, genetic information, protected veteran status, disability, or any other basis protected by local, state, or federal law.
