Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.\nOur work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.\nAbout the Role\nAs Harmattan AI develops advanced autonomous drone systems and payloads for defense applications, our engineering teams are scaling rapidly. To support this growth, our internal Tooling team needs a dedicated Software Engineer - Visualization to build the software infrastructure that accelerates development, testing, and validation.\nIn this role, you will design and deliver the critical internal tools that allow our Guidance, Navigation, and Control (GNC), Machine Learning (ML), Embedded Software, and Validation teams to see, explore, and make sense of massive datasets-including telemetry, sensor data, simulation outputs, flight paths, and complex 3D scenes. You will have high ownership and direct mission impact, building infrastructure used daily across all technical teams.\nResponsibilities\nDesign & Development: Design, develop, and maintain high-performance visualization tools, telemetry dashboards, data plotting software, and 3D scene viewers from scratch.\n\nArchitecture & API Design: Define clean, sustainable solutions (architecture, internal APIs, and intuitive user interfaces) responding to specific technical needs from engineering teams.\n\nPipeline Integration: Ensure all custom visualization tools integrate seamlessly into the company's automated CI/CD and data processing pipelines.\n\nPerformance Optimization: Analyze and continuously optimize the performance, rendering, and responsiveness of visualization tools handling real-world data at scale.\n\nCross-Functional Collaboration: Partner directly with user teams (GNC, ML, Embedded, Validation) to translate operational feedback and field requirements into technical specifications.\n\nQuality Assurance: Write clean, robust code, contribute to tests, improve automated quality evaluations, and document workflows via tutorials.\n\nTechnical Standards: Set technical standards for internal software tools and mentor junior developers as the organization scales.\n\nCandidate Requirements\nTechnical Competencies & Experience\nProfessional Experience: Minimum of 3 years of professional software engineering experience, ideally with a background in robotics, aerospace, or building specialized data visualization platforms.\n\nCore Languages: Strong, production-grade software development skills in C++ and Python.\n\nUI Frameworks: Solid experience building desktop user interfaces or visualization graphics using the Qt framework.\n\nGraphics & Visualization: Proven experience creating data or 3D visualization tools, custom charting libraries, dashboards, or 3D scene renderers.\n\nDevelopment Environment: Complete comfort in a Linux development environment combined with cross-platform build knowledge using containerization tools like Docker.\n\nPreferred Qualifications (Nice to Have)\nPractical experience building applications or software libraries that interface directly with drones, autonomous payloads, or robotic architectures.\n\nA baseline understanding of a drone's embedded software stacks (e.g., GNC logic loops, gimbal control, video streams, or embedded hardware).\n\nFamiliarity with CI/CD automation and orchestration tools.\n\nEducational Background\nIdeally an MSc or BSc in Computer Science, Software Engineering, Robotics, or a similar technical field. Equivalent professional engineering experience is equally valued.\n\nLeadership & Professional Attributes\nComplex Project Management: Avid learner with a demonstrated capacity to handle large-scale, complex projects from initial scoping and prioritization through rapid, iterative deployments-offering innovative solutions and leading teams to deliver outstanding results.\n\nUser Empathy & Design Sensitivity: Empathetic to the pain points of internal user teams; sensitive to software design, ergonomic efficiency, and clean UX.\n\nAdaptability & Mobility: Thrives under pressure in a fast-paced, highly dynamic environment; displays strong curiosity and a healthy “no-task-is-too-small” mentality to maintain continuous deployment workflows.\n\nCommunication & Influence: Excellent written and verbal communication skills, capable of leading and collaborating with diverse principals-from junior team members to senior executives and group leaders.\n\nCommitment: 100% dedication to Harmattan AI’s mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence.\n\nWe look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.","description_format":"text","description_chars":5022,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2026-06-23T13:56:08Z"}],"visa":[],"liveness":{"score":30,"band":"fade","label":"Fading","p_open":1,"p_active":0.671,"p_room":0.44,"age_days":107,"expected_fill_days":85,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-09T06:01:00Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-software-engineer-visualization","json_url":"https://alion.io/job/harmattan-software-engineer-visualization.json","meta":{"generated_at":"2026-10-10T00:42:26Z","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","counted_by":"address","units_charged":1,"used_today":1093,"day_limit":5000,"remaining_today":3907,"minute_limit":60,"resets_at":"2026-10-11T00:00:00Z"}},"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":8839},"rest":"https://alion.io/mcp/rest/get_company?id=8839"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fharmattan-software-engineer-visualization"},{"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%2Fharmattan-software-engineer-visualization"},{"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%2Fharmattan-software-engineer-visualization"},{"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/harmattan-software-engineer-visualization\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-software-engineer-visualization"}]}
