Internship position for World Models for Software Architecture (Constructor Fabric)

Worldwide | Oct. 14, 2026

Report as Closed

Company: Constructor Labs

Country: Worldwide

Type: Onsite

Employment: Full-time

Description: <p><strong>About the Project</strong></p> <p>Constructor Fabric turns a company's informal knowledge into production software through a pipeline of composable capability units called <em>gears</em>: requirements → architecture → product fit → framework (G1) → application → runtime. We are building a <strong>World Model</strong> over that pipeline — a model that does not just generate code, but predicts the <em>consequences</em> of an architectural decision: total cost of ownership, unintended side effects, latency and failure behaviour, and whether a proposed composition is even admissible.<br>The central object is not a digital twin of the application but its <strong>formal architectural skeleton</strong>: gear contracts (GearSpec), a typed attributed hypergraph of the application (AppGraph), a composition algebra that defines which assemblies are legal, and several semantic projections (types, protocols, resources, security) over which properties are proved, refuted by counterexample, or reported as an explainable <strong>gap</strong>. All of it is written in a <strong>domain-specific language</strong> whose syntax trees and graphs we keep in a projectional editor (JetBrains MPS) — so the DSL is not a convenience layer, it is the thing that defines the model's state space and the boundary of what the model is allowed to propose.</p> <p><strong>Internship Role</strong></p> <p>As a Research Intern (Machine Learning for Software Engineering), you will support the data and modelling work behind the World Model — mining code, building datasets, and running baseline experiments. We are looking for students who are keen to collaborate with industrial companies working with AI, open to out-of-the-box topics, and interested in a long-term collaboration.</p> <p><strong>Key Responsibilities</strong></p> <ul> <li>Mine open-source repositories and extract architecture, dependency, and interface graphs from code.</li> <li>Help build and clean (specification → architecture) datasets, including synthetic project generation.</li> <li>Implement and evaluate baseline models (heuristic search, graph ML, or LLM generation) for single pipeline steps.</li> <li>Benchmark models against shared datasets and metrics to compare approaches.</li> <li>Build evaluation harnesses and track experiments reproducibly.</li> <li>Assist with documentation and, where relevant, publication activities.</li> </ul> <p><strong>Required Qualifications</strong></p> <ul> <li>Currently enrolled in a BSc/MSc in Computer Science, Data Science, Mathematics, or similar.</li> <li>Experience with Python and ML frameworks (PyTorch, scikit-learn).</li> <li>Interest in machine learning for code, software engineering, or formal methods.</li> <li>Good English and teamwork skills.</li> </ul> <p><strong>Desired Qualifications</strong></p> <ul> <li>Predictive models/time-series/etc.</li> <li>LLM tooling.</li> <li>Familiarity with graph machine learning (PyTorch Geometric or DGL).</li> <li>Interest in formal methods, program or static analysis, or working with code structure (e.g. AST manipulation, tree-sitter, or repository mining).</li> </ul> <p><strong>Application Details</strong></p> <p>Please submit:</p> <ul> <li>CV</li> <li>Short motivation letter (max. 1 page) explaining your interest and relevant skills</li> <li>Transcript of records (GPA obligatory)</li> </ul>
