Constructor Knowledge Labs

Constructor Knowledge Labs (CKL), Bremen, Germany In collaboration with Constructor University and Constructor Technology Duration: Flexible ABOUT THE POSITION Constructor Knowledge Labs (CKL) invites applicants for a research internship in the area of knowledge discovery and representation, with a focus on transforming unstructured data into interpretable, navigable, and actionable cognitive structures. The internship is embedded in an active research direction jointly developed with Constructor University and Constructor Technology, exploring how modern AI systems (particularly large language models and graph-based methods) can be used to construct shared cognitive maps from heterogeneous knowledge sources such as scientific publications, educational materials, and digital artifacts. The intern will work closely with researchers and engineers on ongoing research activities, contributing to the design, implementation, and evaluation of methods for knowledge representation, semantic structuring, and adaptive reasoning. The position offers hands-on exposure to applied research at the intersection of AI, knowledge graphs, and human-centered knowledge systems. ---------------------------------------------------------------------------------------------------------------------------------- MAIN RESPONSIBILITIES: * Prepare and organize research data, including text collections, research publications, datasets, and related metadata, for use in analytical and modeling tasks. * Work with unstructured and semi-structured data, supporting its analysis and transformation into structured representations such as knowledge graphs, semantic annotations, or concept mappings. * Assist in selected research experiments and analytical tasks related to knowledge discovery, reasoning, or information extraction, under supervision. * Conduct literature review and support research documentation, with potential contribution to internal reports or academic publications. ---------------------------------------------------------------------------------------------------------------------------------- REQUIREMENTS: * Currently enrolled in a BSc or MSc program in Computer Science, Data Science, AI/ML, or a closely related field. * Solid programming skills, preferably in Python. * Basic familiarity with machine learning concepts and data processing workflows. * Strong analytical thinking and interest in research-oriented work. * Good written and spoken English. ---------------------------------------------------------------------------------------------------------------------------------- WE OFFER * Research internship with flexible duration in an international, interdisciplinary research environment. * Participation in active research projects at the intersection of AI, knowledge systems, and applied research, with a clearly scoped internship-level contribution. * Close supervision and mentoring by leading PIs and senior researchers, whose work shapes current research agendas and attracts significant scholarly attention and citations. * Opportunity to contribute to academic publications, embedded in established research groups with consistent presence at top-tier conferences and journals. * Flexible working arrangements, including hybrid or remote options. ---------------------------------------------------------------------------------------------------------------------------------- APPLICATION DETAILS Please submit the following documents in English: * CV * Short motivation letter (max. 1 page) explaining your interest and relevant skills * Transcript of records (GPA obligatory) Deadline for full consideration: Applications are reviewed on a rolling basis

The Reality The frontier models are converging into commodities; the engine is no longer the differentiator. The scarcity in 2026 is not the model. We are not looking for people to fine-tune Llama on toy datasets or write "better prompts." We are building the runtime systems that turn probabilistic token generation into reliable workers that finish 50-step tasks without spiraling. We are solving the math of multi-step reliability through engineering, not wishful thinking. What You Will Solve You will work on the Agentic Harness, treating the LLM as a component within a larger, deterministic control system. Your research will focus on: * Architecting loops that survive error accumulation. You will build verification layers that force the agent to recognize its own hallucinations and self-correct. * You will implement systems where the agent compiles its own constraints and the harness enforces them via constrained decoding or external execution. * You will optimise KV-cache hit rates and design "restorable compression" strategies to prevent attention decay. Who We Are Looking For We are looking for systems thinkers who happen to know ML, not the other way around. * You know that a demo is not a product. You are interested in the "boring" engineering: state machines, retries, idempotency, serialisation — that actually makes agents work. * You are comfortable working with the raw output of the model and building robust software in Python or Rust around it. * You understand why dynamic tool loading destroys inference economics. You prefer deterministic guardrails over "prompting it to be nicer." * You are willing to read a 500-line trace of a failed agent loop to find the exact moment the context drifted. You care about the "last mile" of reliability.
