Continuous learning and technical curiosity are strongly encouraged.\nAs part of the Robotics System Team, you will design and develop algorithms for real-time industrial robotic systems.\nTeam Structure & Focus Areas\nOur team consists of three algorithmic tracks. While you will primarily focus on one area, close collaboration across teams is common.\nControl Algorithms\nReal-time trajectory control, robot dynamics, multibody modeling, and precision execution.\nMotion Planning\nCollision checking, sampling-based planning, optimization-based planning, and high-speed bin-picking motions.\nPacking Algorithms\nGeometric reasoning, packing optimization, item placement strategies, and combinatorial search.\nTo support the growth of our Packing Algorithms team, we are looking for a Robotics Algorithm Engineer (Optimization & Packing). In this role, you will develop algorithms for geometric reasoning, item placement, and space optimization used in real-world robotic applications across logistics and warehouse automation.\nResponsibilities\nDesign and implement robust algorithms for 3D bin packing, container/trailer loading, and space optimization - ensuring maximal utilization and compliance with physical and operational constraints. \nWork with spatial reasoning, 3D geometry, collision detection, and geometric data structures (e.g., for crates, pallets, container interiors). \nIntegrate packing logic with MujinOS’s real-time motion planning and digital-twin workflows to feed downstream robotic behavior. \nCollaborate with robotics, perception, and systems teams to ensure that packing algorithms align with robot kinematics, motion planning, and real-world operational constraints (weight, stacking rules, fragile items, rotation limits, etc.). \nProfile, test, and optimize algorithms for high performance and scalability - able to run in real time or near-real time in high-throughput logistics environments. \nWork closely with operations, product management, and customers to translate ambiguous or variable real-world constraints into robust, production-ready technical solutions.\nRequired Qualifications\n5+ years of professional software engineering experience. \nStrong proficiency in Python and C++. \nDeep understanding of algorithms, computational geometry, spatial data structures, bin/packing / space-optimization problems, or operations research. \nFamiliarity with optimization frameworks or ability to design custom heuristics/solvers (heuristics, meta-heuristics, constraint or combinatorial optimization). \nExcellent problem-solving skills and ability to convert ambiguous real-world constraints (logistics/trucking/warehouse rules) into concrete, maintainable software. \nStrong communication skills and a collaborative mindset; comfortable working in cross-functional teams combining software, robotics, operations, and product stakeholders. \nExposure mixed-SKU palletizing, container loading/unloading, or dynamic storage/packing systems. \nProfessional working proficiency in English (spoken and written). \nNice to Have\nExperience in logistics, warehouse automation, robotics, or supply chainsystems. \nFamiliarity with robotic control pipelines, motion-planning frameworks, or integration of algorithms into autonomous systems. \nExperience with 3D visualization tools or frameworks (for simulation or debugging). \nWhy Mujin?\nYour work doesn’t stay in simulation-your algorithms become production-grade, real-world applications such as palletizing, picking, and depalletizing that run on factory floors globally.\nYou will work on real industrial robotics problems, and your algorithms will be deployed rapidly to solve previously impossible automation challenges.\nOur team is made up of experienced robotics specialists from top global programs (e.g., NTU, CMU, Stanford). You’ll work alongside supportive teammates and mentors who share knowledge openly and help each other grow.\nWe develop the core of the Mujin platform in-house, unifying planning, perception, simulation, and control so we can shape the entire system with complete autonomy.\nHiring Process\nCoding Assessment: Initial technical evaluation.\nHR Interview: Discussion with Human Resources.\nHiring Manager Interview: One or two rounds with the hiring manager.\n Take-Home Assignment & Feedback Interview (If Applicable): A task to complete on your own, followed by a feedback session.","description_format":"text","description_chars":4665,"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":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Continuous learning"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Logistics & Warehouse Robotics","Industrial Robotics","Robotic Software & Control Systems"],"lifecycle":[{"event":"open","at":"2026-09-02T09:35:27Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":48,"expected_fill_days":218,"reasons":["conf:2","win:early"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/mujin-robotics-algorithm-engineer-optimization-packing","json_url":"https://alion.io/job/mujin-robotics-algorithm-engineer-optimization-packing.json","meta":{"generated_at":"2026-10-20T06:51:40Z","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":7540,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":9678},"rest":"https://alion.io/mcp/rest/get_company?id=9678"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmujin-robotics-algorithm-engineer-optimization-packing"},{"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%2Fmujin-robotics-algorithm-engineer-optimization-packing"},{"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%2Fmujin-robotics-algorithm-engineer-optimization-packing"},{"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/mujin-robotics-algorithm-engineer-optimization-packing\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmujin-robotics-algorithm-engineer-optimization-packing"}]}
