Our innovative and proprietary concept is focused on providing satellite and launch vehicle connectivity as-a-service, enabling clients to efficiently manage their assets and fully exploit data. Our GSaaS solutions have been recognized by the market for their efficiency, security, and effectiveness in supporting different applications, from remote sensing to IoT communications.\nJOB OVERVIEW\nWe're building a satellite-based mesh network that builds on top of our Leaf Line service, and we need a Software Engineer to design and build the software at its core - the ground-segment services, protocol implementations, and network layers that move data between the mesh nodes. You'll take ownership of complex software components end to end, contribute to technical decisions, and help drive engineering quality across the team. This is a hands-on senior role for someone who is as comfortable in protocol details and network internals as in system design.\nRESPONSIBILITIES\nDesign, build and maintain core software components for the mesh network's ground segment and data-handling services.\n\nImplement and integrate protocols and services for space data systems (e.g., telemetry/telecommand, file delivery) across the link between spacecraft and ground.\n\nDevelop network software - protocol handling, routing, and data transport - for reliable, high-throughput communication across a dynamic constellation.\n\nDesign and operate cloud-based, distributed services that are scalable, observable, and resilient.\n\nContribute to technical design through design reviews, interface definition and architecture discussions.\n\nWrite high-quality, well-tested, maintainable code and champion engineering best practices (testing, CI/CD, code review).\n\nShare knowledge and support other engineers through code reviews and technical collaboration.\n\nCollaborate closely with mission analysis, network, and platform teams to turn requirements into robust software.\n\nQUALIFICATIONS AND STUDIES\n5-7 years building production software, with a track record of owning significant components or systems.\n\nREQUIREMENTS\nTech skills\n\nStrong software development skills in languages such as C/C++, Go, Python, or Rust.\n\nSolid Linux experience - development, networking, and working close to the OS.\n\nHands-on cloud experience (AWS, GCP, or Azure) building and operating distributed services.\n\nNetwork programming experience - sockets, protocol design/implementation, TCP/UDP, and data transport internals.\n\nExperience with networking protocols; experience with space data systems is considered a plus.\n\nExperience with Delay Tolerant Networking (DTN), mesh networking or routing protocols is considered a plus.\n\nExperience contributing to system design.\n\nAwareness of secure software development practices and relevant compliance (NIS2, ISO 27001).\n\nSoft skills\n\nExcellent cross-functional communication skills to interface effectively with engineering teams, suppliers and management.\n\nStrong analytical and problem-solving skills with the ability to collaborate effectively across multidisciplinary teams.\n\nRigorous, detail-oriented approach, with a preference for measured/verified data over assumptions, and transparency when prior estimates need correction.\n\nComfortable working in a fast-moving, still-maturing product environment, iterating on both architecture and hands-on implementation.\n\nFluent English (written and spoken) required, given interaction with external international partners\n\nWHAT WE OFFER\nA flat and collaborative organizational structure\n\nA fast-paced and professional environment within a rapidly growing space scale-up\n\nChallenging projects with real impact on the global space ecosystem\n\nAn international and diverse workplace\n\nMeal vouchers (€8/day) · Welfare platform · Hybrid work · Training opportunities\n\nCOMPENSATION & TRANSPARENCY:\nReports to: Head of Engineering\n\nCareer level: P4 - Senior Professional\n\nJob location: Lomazzo (Como), Italy | Hybrid work model\n\nSalary range: 55-70K\n\nVariable compensation: 10% of annual gross salary\n\nBenefits: Competitive benefits package, including a welfare platform and meal vouchers in Italy, with equivalent local benefits provided where applicable\n\nExpected start date: 1.10.2026","description_format":"text","description_chars":4402,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Hybrid work"],"hiring_locations":[{"name":"Italy","iso":"IT","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-11T04:11:48Z"}],"liveness":{"score":29,"band":"fade","label":"Fading","p_open":0.9,"p_active":0.589,"p_room":0.55,"age_days":52,"expected_fill_days":42,"reasons":["conf:69","win:tail"],"computed_at":"2026-09-26T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/leaf-senior-backend-software-engineer","json_url":"https://alion.io/job/leaf-senior-backend-software-engineer.json","meta":{"generated_at":"2026-09-27T03:45:38Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3501,"day_limit":5000,"remaining_today":1499,"minute_limit":60,"resets_at":"2026-09-28T00:00:00Z"}}}
