Your work will focus on developing advanced methods for semantic structure extraction, conceptual and argumentative flow reconstruction, rationale-aware content generation, metacognitive prompting, and adaptive personalization. Core research contributions will include designing algorithms for concept and structure extraction, building neural/graph hybrid models for pedagogical reasoning, implementing ontology-alignment methods for cross-domain transfer, and creating human-in-the-loop optimization pipelines that incorporate expert feedback-aligning with the multi-year research roadmap (WP1-WP3) .\nAs a postdoctoral researcher, you will take a leading role in designing experiments, shaping research directions, supervising junior researchers (including PhD students), and contributing to the development of end-to-end demonstrator systems capable of generating structured, rationale-rich, and learner-adaptive content. You will be responsible for coordinating data annotation efforts, overseeing the construction of evaluation frameworks, and driving publication-quality research outputs, including survey papers, methodology papers, and cross-domain transfer studies. Interdisciplinary collaboration is strongly encouraged, especially at the intersection of computer science, computational linguistics, cognitive science, and learning technologies, and you will have opportunities to initiate or co-lead joint projects with internal and external partners.\nThe postdoctoral researcher will also contribute to teaching in areas such as Machine Learning, NLP, AI for Education, Explainable AI, and Python-based applied seminars, supporting course development and supervising Bachelor’s, Master’s, and PhD theses. The university provides a supportive academic environment-including mentoring, administrative support, computational resources, and opportunities for technology transfer and industry engagement-enabling the postdoctoral researcher to establish or strengthen an internationally visible research profile.\nMandatory requirements\nPhD degree in Computer Science, Artificial Intelligence, Machine Learning, Computational Linguistics, or a closely related field.\nStrong publication record in relevant top-tier venues (e.g., NeurIPS, ACL, ICML, ICLR, AIED, LAK, AAAI).\nDemonstrated expertise in at least two of the following areas:semantic parsing or structured NLP\nknowledge representation, reasoning graphs, or GNNs\nnatural language generation, explainability, or rationale modeling\nontology alignment, cross-domain transfer, or representation learning\npersonalization algorithms, metacognition, or educational AI\nhuman-in-the-loop systems or RLHF\n\nExperience in leading research tasks, mentoring junior researchers, and coordinating multi-stage projects.\nFluency in Python and modern deep learning frameworks (PyTorch/TensorFlow).\nStrong analytical, communication, and academic writing skills.\nDemonstrable ability to design rigorous experimental pipelines and validation methodologies.\nResponsible, independent, and proactive research personality with strong teamwork skills.\nIntercultural experience and readiness to work in an international research environment.\nFluency with AI co-pilot assistants for coding and writing.\nFluency in English, the primary language of research and instruction on campus.\nPreferred qualifications:\nExperience in developing research prototypes, evaluation benchmarks, or large-scale datasets.\nPrior involvement in interdisciplinary or applied research projects.\nPotential to contribute to competitive funding applications.\nExperience with open-source releases or reproducible research pipelines.\nApplication Details\nStarting date: September, 2026\nContract: Full-time (100%), TV-L E13\nWork mode: Hybrid\nApplication package must include:\nCurriculum Vitae (CV);\nA detailed letter of motivation outlining research interests and career goals;\n2 recommendation letters;\nApplications to be reviewed on a rolling basis. Shortlisted candidates will be invited to interviews.","description_format":"text","description_chars":4263,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Research Institutes"],"lifecycle":[{"event":"open","at":"2026-09-13T05:41:43Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.134,"p_room":0.28,"age_days":330,"expected_fill_days":25,"reasons":["conf:4","win:tail","crowd:"],"computed_at":"2026-11-05T05:54:30Z"},"pay":{"stated_usd_annual":109346,"is_top_pay":false},"html_url":"https://alion.io/job/constructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation","json_url":"https://alion.io/job/constructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation.json","meta":{"generated_at":"2026-11-05T06:04:09Z","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":7476,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":720007},"rest":"https://alion.io/mcp/rest/get_company?id=720007"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fconstructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation"},{"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%2Fconstructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation"},{"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%2Fconstructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation"},{"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/constructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconstructorknowledgelabs-postdoctoral-researcher-ai-for-semantic-structures-reasoning-flows-personalized-content-generation"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":854877}},{"tool":"search_jobs","arguments":{"company":"constructorlabs.org","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":854877},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
