Aalyria is a company dedicated to creating, organizing, and managing the world's most advanced networks to enable ubiquitous connectivity at the speed of discovery. It utilizes atmospheric laser communications technology and a software platform originally developed by Alphabet. Aalyria's platform orchestrates networks across land, sea, air, space, and beyond. Key technological components include Tightbeam, a free space optics technology, and Spacetime, a software platform for network orchestration. Aalyria is backed by significant investors and has engaged in various high-profile projects, including working with NASA and developing 5G/6G networking platforms.

📋 Description

• Understand and, in some cases, end-to-end system architectures for Non-Terrestrial Networks (NTN) with knowledge of the end-to-end service chain (UE → RAN → Core → Transport/SDN (inc. front, mid and back-haul) → Service layer) • Lead customer engagement and projects around architecture for LEO/GEO/MEO and multi-orbit satellite systems integrated with 3GPP 4G/5G (Rel-17+) and future 6G concepts • Own architectural blueprints, interfaces, and decomposition across space segment, ground segment, and mobile network domains, in particular in their interactions with Aalyria’s Spacetime. • Lead customer solution architecture, requirements collection and translation into Spacetime requirements and project execution • Drive technology selection and trade-off analyses, where needed • Drive technical proposal writing for commercial and public sector customers • Design and optimize radio resource management (RRM), scheduling, beam management, mobility, and interference coordination mechanisms • Support development of customer resource management solutions and Spacetime algorithms to be implemented by Aalyria Spacetime software engineering team • Address satellite/NTN-specific constraints (Doppler, delay, ephemeris, beam hopping, power limits, feeder link constraints) • Drive the design and support the implementation in Spacetime of advanced orchestration and resource management capabilities for Direct-to-Cell architectures, including spectrum reuse, sharing and coexistence with terrestrial MNO networks • Ensure RRM and Spacetime implementation alignment with regulatory and spectrum constraints (ITU-R, regional regulators) • Understand, interpret and apply 3GPP specifications (RAN, SA, CT) relevant to Spacetime for NTN, SCS, and D2D and RAN OAM/orchestration (e.g. RAN3, SA2, SA5) and Mobility (e.g. RAN2, etc) • Contribute to or interface with standards bodies and industry forums (e.g. 3GPP, ETSI, GSMA, O-RAN, ESA NTN Forum, MSSA, etc) • Design network and 3GPP RAN/CN function orchestration and FCAPS • Define interfaces and APIs for automation, orchestration, and inter-domain coordination • Lead specific technical customer or prospective customer engagements, proposals, including also applications to public sector grant proposals across US, UK, EU and globally (e.g. ESA, UKSA NTIA, NSF, etc) as needed, and conduct technical reviews • Translate high-level requirements into implementable technical architectures • Act as technical authority across engineering, product, and partner teams.

🎯 Requirements

• Strong background in 4G/5G mobile network architecture (RAN + Core) • Proven experience and understanding in SATCOM system architecture (space + ground) • Deep understanding of 3GPP architecture, protocols, and interfaces • Hands-on knowledge of RAN concepts: PHY/MAC, scheduling, mobility, beamforming, interference • Experience producing architecture documents, system diagrams, and technical specifications • Understanding of 3GPP APIs, RAN OAM and control plane concepts, networking protocols and interfaces • Understanding of concepts of cloud native, NFV, orchestration and automation, network automation and orchestration APIs, etc • Strong communication and leadership skills, ability to interface with business stakeholders in the telco, satcom and defense sectors at all levels and work collaboratively in a cross-cultural team environment.

🏖️ Benefits

• Competitive compensation package based on experience • Hybrid working policy with flexible arrangements • Opportunity to lead high-impact, innovative projects in the space technology and digital infrastructure domain. • A dynamic, international environment collaborating with leading research centres and industrial partners. • Exposure to cutting-edge technologies in space-ground integration, AI-driven networks, and cloud mission control.
