You turn customer, mission and standards requirements into a coherent architecture spanning space segment, gateways, networks and user terminals, and steer it through integration, verification and deployment with internal teams, suppliers and partners.1. End-to-end system architecture\nArchitect the hybrid satellite-terrestrial (NTN-TN) solution, ensuring seamless interoperability for mobility and handheld use cases.\nDefine, manage and trace user-terminal (edge/handheld) and gateway requirements into system architectures compliant with 3GPP (Rel. 15+, incl. Rel. 17+ NTN), ETSI, ITU and FCC.\nOwn end-to-end mission interfaces: spaceborne platform and payload software, terminal RF control, protocol stacks, integrated modems and battery management.\nLead the architecture of digital hardware (modems, modem accelerators, application processors), physical layer and protocol-stack software.\nDefine network strategies for LEO/MEO/GEO constellations with 5G/LTE/RedCap, including RAN, core and transport design for low-latency, high-throughput connectivity.\nSpecify feeder-link requirements for data and control exchange between TN and NTN; set spectrum-sharing, interference-mitigation and beamforming strategies.\n2. Integration, verification & validation\nGuide network planning and simulation with the network design team.\nWrite integration and system test specifications; oversee breadboard validation of critical building blocks.\nSteer lab, over-the-air (OTA) and drive testing, proof-of-concepts and demonstrations that prove NTN-TN interoperability.\nSafeguard end-to-end service provisioning and data-path integrity across the full RF communications chain.\n3. Partners, suppliers & delivery\nEvaluate component and subsystem partners; coordinate external technical partnerships.\nDefine system and subsystem sign-off for supplier and subcontractor deliverables: milestones, work packages, plan sign-offs and integration.\nAct as primary technical contact for cellular wireless development and deployment across OIQ’s partner and customer ecosystem.\n4. Collaboration & mentoring\nWork closely with hardware, software and AI colleagues; maintain rigorous architecture documentation (e.g. GitHub).\nWith the CTO, mentor working students, interns and extended team members on 4G/5G NTN-TN connectivity.Your profile\n Essential\nBachelor’s, Master’s or PhD in Electrical Engineering, Wireless Communications, Telecommunications, Computer Science or a related field.\n8+ years’ wireless systems-engineering experience, ideally in cellular handheld and satellite communications (telecom, aerospace or automotive).\nDeep knowledge of 3GPP (incl. Rel. 17+ NTN), 5G NR, LTE, NB-IoT, RAN, core (EPC/5GC) and transport networks.\nStrong RF and link-level expertise: beamforming, MIMO, waveform design, modulation (OFDM, QAM, DSSS), spectrum allocation, interference management and link budgets.\nProficiency in MATLAB, HGSS, ADS, Ansys, Python, C++ or similar simulation tools; experience with embedded/IoT systems, edge AI and cloud-based telematics.\nFamiliarity with RF test equipment and validation platforms (e.g. Keysight, Rohde & Schwarz, Viavi, Anritsu, Spirent, Amarisoft).\nWorking knowledge of Jira, Confluence, GitHub and Microsoft 365; customer-oriented leader and clear communicator, comfortable with ambiguity.\nFluent English; working proficiency in French or German. Valid driving licence (field testing and partner visits).\nPreferred\nLEO/MEO/GEO satellite communications and network slicing; O-RAN, SDN and cloud-native 5G core.\nElectronically steered antennas, phased arrays, mmWave; V2X/C-V2X, edge computing and AI-driven network optimisation.\nExperience in automotive, rail, agriculture, fleet or aerospace connectivity; containerised networking (Kubernetes, Docker).Why OrbitsIQ?\n•30 days’ paid annual leave plus 24 and 31 December, in addition to Luxembourg’s 11 statutory public holidays (statutory minimum: 26 days).\nCompetitive salary and Luxembourg social-security coverage (health, pension, accident insurance).\nFlexible working hours; hybrid work applied within cross-border telework thresholds for residents of France, Belgium and Germany.\nReal architectural ownership in a multinational, collaborative start-up with short decision paths, visionary leadership and a strong investor and partner network.\nContribution to fitness or health-related activities, and support for professional development.\n•A multinational, collaborative start-up with short decision paths, visionary leadership and a strong investor and partner network, and the chance to shape the future of mobility, handheld connectivity and space.","description_format":"text","description_chars":4782,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"French","level":"Advanced (C1)","optional":false},{"language":"German","level":"Advanced (C1)","optional":false},{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Annual leave","Flexible schedule","Hybrid work","Professional development"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"},{"name":"France","iso":"FR","kind":"country"},{"name":"Belgium","iso":"BE","kind":"country"},{"name":"Luxembourg","iso":"LU","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-03T09:28:15Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":32,"reasons":["conf:1","win:early"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/orbitsiq-global-hybrid-connectivity-systems-engineer-architect","json_url":"https://alion.io/job/orbitsiq-global-hybrid-connectivity-systems-engineer-architect.json","meta":{"generated_at":"2026-11-05T12:55:19Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":16679,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2490527},"rest":"https://alion.io/mcp/rest/get_company?id=2490527"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Forbitsiq-global-hybrid-connectivity-systems-engineer-architect"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Forbitsiq-global-hybrid-connectivity-systems-engineer-architect"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Forbitsiq-global-hybrid-connectivity-systems-engineer-architect"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/orbitsiq-global-hybrid-connectivity-systems-engineer-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Forbitsiq-global-hybrid-connectivity-systems-engineer-architect"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3671979}},{"tool":"search_jobs","arguments":{"company":"oiqglobal.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3671979},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
