We automate high-stakes, knowledge-intensive workflows traditionally trapped in siloed data, fragmented tools and tacit (undocumented) human expertise.\nOur multi-agent systemsperform complex reasoning in the physical world; and transform bespoke, service-heavy processes into scalable Service-as-a-Softwareautomation.\nCONXAI is trusted by some of the leading AEC companies in Europe, US, LATAM and Japan.\nYour Role\nAs a Senior ML Engineer, you will lead the development of the spatial reasoning engine for our agentic AI platform. Your work focuses on the intersection of 3D Semantic Reconstruction, Geometric Deep Learning, and Agentic Inference. You will be responsible for building pipelines that transform unstructured multi-modal data into structured, actionable Spatial Knowledge Graphs.\nYou will prioritize topological accuracyand semantic grounding, over photorealistic neural rendering. You will design the logic that allows autonomous agents to navigate, reason about, and perform inference on complex 3D environments, ensuring that AI-driven insights are rooted in the physical and engineering constraints of the real world.\nWhat You’ll Do\nSemantic Scene Reconstruction:Develop algorithms for 3D scene representation that prioritize geometric primitives and semantic labels over pixel-accuracy. This includes surface reconstruction, occupancy mapping and volumetric segmentation\nMulti-Modal Fusion:Architect systems that fuse panoptic segmentation representations from CONXAI’s AEC Foundation model with 3D models to generate high-fidelity, labeled representations\nKnowledge Graph Augmentation:Automate the augmentation of 3D spatial data to CONXAI’s Spatio-Temporal Knowledge Graphs, from reconstructed 3D scenes, mapping the hierarchical and functional relationships between structural elements\nAgentic Inference & Reasoning:Design agentic workflows that perform complex reasoning tasks directly on the STKG\nActionable Affordance Mapping:Implement methods to identify \"affordances\" within a 3D volume, defining how agents or users can interact with the environment based on its physical geometry and engineering logic\nOptimization & Scaling:Deploy SOTAmodels, representations and inferred domain context into production use-cases that deliver significant value to customers\nWhat We’re Looking For\nMS / PhD in Computer Science, Robotics, Electrical Engineering or related field\n3+ years of industry experience in Computer Vision and Deep Learning\n2+ years of leading 3D Computer Vision projects, specifically, geometric deep learning, 3D reconstruction\nExperience with physics engines, e.g., NVIDIA Isaac Gym, MuJoCo, PyBullet, etc. is a plus\nExperience in Agentic AI implementations with GraphRAG, Langgraph/LlamaIndex is a plus\nExceptional implementation experience with Open3D / PyTorch 3D, reconstruction (multi-view stereo, surface reconstruction and mesh-fitting, e.g., with TSDF), 2D → 3D “lifting”\nThorough understanding of software design\nPrevious experience in a fast-paced technology startup environment is a plus\nFluent and articulate in English\nWhy CONXAI\nEdge of Innovation:Be at the absolute forefront of AI in the construction tech space\nHigh Autonomy:Contribute to a new paradigm for multi-modal scene understanding and reasoning - owning the logic, performance, and customer impact\nTop-Tier Peer Group:Work with a global team of ML engineers, software engineers and industry practitioners\nEquity & Scale:Competitive compensation with significant equity upside","description_format":"text","description_chars":3656,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotic Software & Control Systems","Artificial Intelligence","Edge AI","Explainable AI (XAI)"],"lifecycle":[{"event":"open","at":"2026-10-04T20:21:04Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.169,"p_room":0.28,"age_days":202,"expected_fill_days":30,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/conxai-sr-computer-vision-engineer-3d-semantic-scene-understanding","json_url":"https://alion.io/job/conxai-sr-computer-vision-engineer-3d-semantic-scene-understanding.json","meta":{"generated_at":"2026-10-18T14:53:46Z","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":21202,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":3781159},"rest":"https://alion.io/mcp/rest/get_company?id=3781159"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fconxai-sr-computer-vision-engineer-3d-semantic-scene-understanding"},{"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%2Fconxai-sr-computer-vision-engineer-3d-semantic-scene-understanding"},{"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%2Fconxai-sr-computer-vision-engineer-3d-semantic-scene-understanding"},{"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/conxai-sr-computer-vision-engineer-3d-semantic-scene-understanding\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconxai-sr-computer-vision-engineer-3d-semantic-scene-understanding"}]}
