We partner with multiple UAV manufacturers to deliver cost effective capabilities to public sector and defence customers. Our core team has substantial experience in aerospace engineering and developing computer vision applications across Europe, including at companies like Bolt, Ericsson, and Milrem.\nAs a Software Engineer on the SW Platform team, you will be responsible for the hands-on design, development and testing of firmware and software enabling Lendurai’s autonomous drone solutions. This role requires a strong production experience with C++; you will deliver reliable code in a environment and continuously contribute to the development of the product.\nWhat you will be doing\nDevelop and maintain software and firmware platform that enables our products to leverage visual guidance and machine learning for advanced drone capabilities\n\nPort our software platform to various hardware and software combinations based on market demand and technical requirements.\n\nDevelop and maintain tooling related to testing, development, provisioning, and manufacturing of Lendurai’s products\n\nSet up, improve and maintain infrastructure for software development (CI/CD, automated testing, backend services, etc)\n\nWork with internal and external stakeholders to implement APIs and 3rd party integrations (RESTful APIs, data processing, ground control stations, etc)\n\nWork with stakeholders to map critical workflows (e.g pre-flight, in-flight, post-mission) into an intuitive and powerful UX.\n\nWe are looking for\nRequired skills:\nFluency in C++14/C99 on Linux; strong grasp of multi-threading, performance profiling, and GPU/CPU memory constraints.\n\nBuilt and shipped across different engineering domains: software, firmware/embedded.\n\nDemonstrated capability of picking up and delivering in unfamiliar domains, quick learning\n\nAdditional skills that are nice to have:\nTrack record designing controller- or touch-first interfaces that remain usable under stress and glare.\n\nFamiliarity with at least one cross-platform UI/graphics stack (Unreal, Unity, Qt/QML, Vulkan/OpenGL ES, Dear ImGui).\n\nExperience with realtime video feed processing (e.g GStreamer, ffmpeg).\n\nLow-level Linux device optimisation: power management, GPU driver tuning, buildroot/Yocto.\n\nKnowledge of PX4/Ardupilot and concepts like SITL, MAVLink protocol.\n\nBuilt or supported UAV, robotics, or mobile autonomy platforms in the field, not just in a lab.\n\nBackend development (worked with HTTP, RESTful APIs, databases, or similar)\n\nWhat we offer\nMonthly gross salary of €4,500-6,500, based on experience and impact.\n\nAbility to shape Lendurai’s operational foundation as an early hire.\n\nA high-ownership role at the intersection of UAV operations, autonomy, computer vision, and defence technology.\n\nA mission-driven team that values curiosity, and a hands-on approach to solving defense challenges\n\nEarly technical influence in a growing defense tech startup\n\nJoin Lendurai to help build the operational backbone for the next generation of resilient UAV autonomy.","description_format":"text","description_chars":3216,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-13T16:56:42Z"}],"liveness":{"score":2,"band":"cold","label":"Long shot","p_open":0.9,"p_active":0.088,"p_room":0.28,"age_days":217,"expected_fill_days":25,"reasons":["conf:50","win:tail","crowd:"],"computed_at":"2026-10-02T05:45:00Z"},"pay":{"stated_usd_annual":90492,"is_top_pay":false},"html_url":"https://alion.io/job/lendurai-software-engineer-platform-c","json_url":"https://alion.io/job/lendurai-software-engineer-platform-c.json","meta":{"generated_at":"2026-10-03T03:24:51Z","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":3141,"day_limit":5000,"remaining_today":1859,"minute_limit":60,"resets_at":"2026-10-04T00:00:00Z"}}}
