Location: Bremen, Germany Supervisor: Prof. Dr. Alexander Tormasov About the Position Constructor Knowledge Labs (CKL), in collaboration with Constructor Technology, invites applications for a PhD position in machine learning for software engineering and formal methods, on the Constructor Fabric project. Constructor Fabric turns a company's informal knowledge into production software through a pipeline of composable capability units called gears : requirements → architecture → product fit → framework (G1) → application → runtime. We are building a World Model over that pipeline — a model that does not just generate code, but predicts the consequences of an architectural decision: total cost of ownership, unintended side effects, latency and failure behaviour, and whether a proposed composition is even admissible. The central object is not a digital twin of the application but its formal architectural skeleton : 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 gap . All of it is written in a domain-specific language 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. What you will work on Depending on your background, one or two of: Formal skeleton and composition — GearSpec as a contract $(Requires, Provides, State, Effects, Assumptions, Guarantees, Parameters)$; AppGraph as a typed attributed hypergraph; an algebra of assembly (sequential, parallel, feedback, refinement); semantic projections and system-level invariants over trajectories. Architecture synthesis as an inverse problem — given a specification, load and constraints, find the composition of gears that realises it. Constraint solving and MCTS as the baseline; a learned transition/value model for ranking and pruning; LLM proposals treated strictly as candidate hypotheses that a DSL parser, type checker and property checks must then admit or reject. DSL design and language engineering — the gear DSL and its glue layer decide which AppGraphs are expressible at all, and therefore where the search space ends. This thread covers the abstract syntax and static semantics of that DSL; the requirement that an architectural decision be unbypassable by construction (you must not be able to wire authentication around the Auth Resolver); what happens to the language when gear contracts change or a 201st gear is added; projectional representation of graphs with cycles; and the open hypothesis that a specialised G1-DSL is generated together with every G1. Local transition models and pipeline surrogates — fast approximate predictors for single pipeline steps (spec change → code quality, architecture → product fit, app → runtime outcome), with calibrated uncertainty, validated against real telemetry. Data — reconstructing (specification → architecture) pairs from open repositories at scale, plus synthetic project generation from a fixed gear set and DSL grammar to cover rare transitions, gaps and counterexamples. Profile MSc (or equivalent) in computer science, mathematics, or a mathematical natural science. Coursework in compilers, programming-language theory, language design or model-driven engineering is a strong positive signal, half of this project is deciding what a formal architecture description is allowed to say. Evidence that you finish things: a maintained open-source repository, a peer-reviewed publication, or a strong competition result. Fluent technical English. Most importantly: the habit of stating an assumption explicitly and designing an experiment that could falsify it. Required mathematical background Core skills: Probability and statistics. Estimation, Bayesian inference, uncertainty quantification and calibration (proper scoring rules, reliability diagrams, ECE), experiment design and significance testing. A prediction we cannot calibrate is not usable here. Linear algebra and multivariate calculus at the level needed to derive, not just call, a training objective: matrix calculus, gradients, stochastic optimisation, conditioning. Discrete mathematics and graph theory. Typed and attributed graphs and hypergraphs, subgraph matching and isomorphism, graph rewriting, reachability, basic complexity classes. Mathematical logic and formal methods. First-order logic, type systems, SAT/SMT, temporal logic (LTL/CTL) and model checking, pre/post-conditions, invariants, refinement. Sequential decision making. MDP/POMDP, dynamic programming, model-based RL, latent state-space (world) models, Monte-Carlo Tree Search. Strong command of at least one, working knowledge of a second: Formal languages, semantics and language engineering — grammars (context-free, attribute and graph grammars), derivation and reachability, parsing; abstract versus concrete syntax; operational and denotational semantics; metamodelling, model-driven engineering, model-to-model transformation, and projectional (structural) editing of the kind JetBrains MPS implements. We are asking for the education, not the tool: you should know why a projectional editor exists, what a metamodel buys you over a text grammar, and how a language evolves without breaking its existing models. Hands-on MPS experience is explicitly not required — we will teach it. Category theory for compositional systems — monoidal and traced monoidal categories, functors as semantic projections, string diagrams, operads. This is the language of our assembly algebra. Causal inference — structural causal models, do-calculus, counterfactuals, identifiability. Required for the "what happens if we replace this technology / move on-premises" class of questions, which similarity search alone cannot answer. Queueing theory and applied stochastic processes — M/M/1 and networks of queues, heavy tails, retries, timeouts, partial failure and reliability models. This is the resource and stochastic projection. Combinatorial optimisation, constraint programming and program synthesis theory — CEGIS, version-space algebras, symmetry breaking, search heuristics. Representation learning theory — VAEs and latent dynamics, GNN expressiveness (Weisfeiler-Leman hierarchy), permutation equivariance, embedding migration under a changing vocabulary. Required hands-on programming skills This is an engineering-heavy PhD. We expect code that another person can clone, run and reproduce — not notebooks that worked once. Must have: Python (professional level). Type hints, packaging, `pytest`, profiling, `asyncio`, memory-aware data structures. You write unbuffered, logged, restartable long-running jobs by default. Training loops written from scratch, custom datasets and collation, mixed precision, multi-GPU; experiment tracking (W&B or MLflow), configuration management (Hydra), strict seed and artefact reproducibility. Graph machine learning. PyTorch Geometric or DGL — message passing, heterogeneous and typed graphs, graph transformers, handling graphs whose node vocabulary changes between versions. Solvers and verification tooling driven from Python. Z3 or cvc5 hands-on; demonstrated exposure to at least one model checker (TLA+/TLC, SPIN, NuSMV, Alloy) or proof assistant (Lean, Coq, Isabelle). Code as data. AST manipulation, `tree-sitter`, static analysis, dependency and interface graph extraction, large-scale repository mining. Parallel data pipelines. `multiprocessing`, Ray or Dask; checkpointing, heartbeats, cost estimation before launching a run that touches millions of files. LLM engineering. API orchestration, structured and grammar-constrained decoding, evaluation harnesses, token/cost accounting — with the discipline to treat model output as a hypothesis subject to formal checks. Linux, git, code review, shell. Desirable: Language tooling you have actually used: ANTLR, Xtext, Lark, or a parser, type checker or interpreter you wrote yourself. Our internal representation of gear syntax trees and graphs lives in JetBrains MPS — again, we do not ask for MPS experience, only that you are comfortable reading and extending a metamodel; Java/Kotlin literacy helps once you get there. JAX, or compiler / SAT-SMT internals. Infrastructure literacy — Docker, Kubernetes, Terraform, OpenTelemetry/Prometheus — since the resource projection is calibrated against real deployment telemetry. One systems language (Rust, Go or C++) for performance-critical search. Prior experience with production software architecture, or with a brownfield system you had to change without breaking. Funding The appointment provides full financial coverage through a dedicated fellowship, comprising: Monthly stipend of €1,650 Monthly research-cost allowance of €100 (Forschungskostenpauschale) Health-insurance subsidy of €100 per month Location: Bremen, Germany Duration: 3 years, full time Start date: November 2026 Application package must include CV, including publications, code, or research projects.

Location: Germany About us Constructor Labs is the research arm of Constructor Knowledge, based at Campus Ring 1 in Bremen, Germany. Our work is organized around three units: Knowledge Labs, Cyber Labs and Science Labs. We apply computing, software and robotics research to make scientists, teachers and students more effective, working with institutional partners that include CERN, NUS, Carnegie Mellon and Fraunhofer. Constructor Practice is the hands-on practice platform within the Constructor Technology learning suite, alongside Learn, Assess, Proctor, Schedule and Groups. It spans an unusually broad portfolio: curriculum-aligned virtual science labs; the evidence-based intervention products Calcularis (numeracy and dyscalculia), Grafari/Orthograph (literacy and dyslexia); and browser-based Software & IT and Coding labs for technical training. Shared capabilities include cloud-based hands-on environments with no installation, automated assessment and grading, group assignments and instructor assistance, LMS integration, and learner analytics and dashboards. The product is in production across three distinct markets. Higher education and research, schools and public education authorities, and corporate and vocational training. The platform operates under GDPR, FERPA, COPPA and SOPIPA commitments. About the Role You will own Constructor Practice content portfolio of products (currently includes Practice: Science Labs and Practice: Schools Math and Literacy with future extension to other disciplines) end to end: strategy, roadmap, commercial performance and delivery. This is a lead product management position with full accountability for the product line rather than for a single feature area or squad. The scope is wider than a conventional PM role. You will sit in front of clients during presales, shape the go-to-market with sales and marketing, define the roadmap across a portfolio serving three different buyer types, and work with product owners and engineering to bring releases in on time and on budget. Where the product line needs something that has no owner, it is yours. Practice has an established customer base and a portfolio that has grown through acquisition and expansion into markets with little in common: a Swiss canton buying dyscalculia intervention for primary schools has almost nothing in common with Acronis training its partner ecosystem. Bringing coherence to that portfolio, deciding what to invest in, what to standardize and what to retire, is the central problem of this role. Reporting and scope Reports to: Head of SI and Edu, Constructor Labs. Level: Lead Product Manager. You will lead the product team including product owners, engineers and subject matter experts, with a view to building a larger product team as the line grows. Product surface: all Constructor Practice content products, namely Science Labs, Calcularis, Grafari/Orthograph, Software & IT and Coding, in cooperation with the shared platform layer covering assessment, analytics, LMS integration and deployment. Markets: higher education and research institutions, schools and public education authorities, and corporate and vocational training providers. Interfaces: engineering and product owners, presales and sales, marketing, customer success and support, Constructor Tech engineering and product teams, Nexademy content team, Constructor Labs research, and Constructor Labs Solutions as an integration channel. The role is both outward and inward facing. You are expected to be in client conversations and in sprint reviews in the same week, and to carry what you learn in one into the other. Duties & Responsibilities : Product strategy. Set the direction for Practice across its three markets: where to invest, where to standardize on shared platform capability, and where a module should be sustained rather than developed. Maintain a defensible view of the competitive position against virtual lab providers, intervention software and hands-on technical training platforms. Roadmap and prioritization. Own a published roadmap with a clear rationale for sequencing, balancing client commitments, platform debt, regulatory requirements and new capability. Say no in a way that holds up, and keep the roadmap current as commitments change. Discovery and requirements. Work directly with teachers, learning designers, lab administrators, IT staff and corporate training leads to establish what the product needs to do. Translate that into specifications, acceptance criteria and measurable outcomes rather than feature lists. Delivery with engineering. Work with product owners and development teams through planning, sprint reviews and release. Hold scope, schedule and budget together, escalate early when one of the three has to give, and make the trade-off explicit rather than absorbing it quietly. Presales support. Act as the product authority in qualified opportunities: demonstrations, solution design, technical objection handling, RFP and tender responses, security and compliance questionnaires. Judge which client-specific requests are viable and which are not. Go-to-market. Own positioning, messaging and the launch plan for each release and module, working with marketing and sales enablement. Produce the materials that let the sales team sell Practice without you in the room. Client relationships. Run a regular cadence with reference and strategic accounts, gather structured feedback, manage expectations on committed features and turn successful deployments into case studies and references. Pricing and commercials. Own the pricing and packaging model across modules and market segments, with input on licensing, bundling within the Constructor learning suite, and the commercial terms of custom work. Compliance and trust. Keep the product aligned with GDPR, FERPA, COPPA and SOPIPA obligations and with accessibility requirements, working with legal and security. Child-facing products in public education carry a higher bar, and meeting it is part of the roadmap. Performance measurement. Instrument the product, track adoption, engagement and learning outcomes, and use the evidence to decide what to build next and what to stop. Qualifications & Experience: Product ownership at scale. Five or more years in product management, including at least three owning a B2B SaaS product line with revenue accountability rather than a single feature area. Education or adjacent domain. Experience with EdTech, assessment, e-learning, corporate L&D tooling or another domain where the buyer, the administrator and the end user are three different people with different measures of success. Delivery discipline. A track record of shipping on committed dates and budgets with agile teams, working through product owners and engineering leads, and managing the scope conversations that make that possible. Commercial fluency. Comfort in front of clients and in presales, with the ability to run a demonstration, defend a roadmap position and contribute to pricing and packaging decisions. Technical credibility. Enough depth in cloud platforms, LMS integration standards such as LTI and SCORM, APIs and analytics to hold your own with engineering and with a client's IT team, without needing to write the code yourself. Evidence-based decisions. Fluency with product analytics and experimentation, and the judgement to distinguish a signal worth acting on from a loud customer. Portfolio judgement. Experience managing several products or modules at once, and a willingness to make and defend investment and retirement decisions. Languages. Business-fluent English. German is a bonus, given the Swiss, German and Austrian school and public-sector customer base. Communication. Written and verbal clarity with audiences ranging from a primary school teacher to a university CIO to a development team. Nice to have Experience with virtual labs, simulation environments or browser-based development and IT training environments. Background in special educational needs, learning intervention or evidence-based pedagogy, particularly dyscalculia or dyslexia support. Familiarity with public-sector education procurement in DACH, including cantonal and Länder-level buying. Experience with student data privacy regimes (GDPR in an education context, FERPA, COPPA, SOPIPA) and WCAG accessibility conformance. Prior work in a group structure where a product is sold both directly and through an integration or services channel. A background in teaching, instructional design or learning science. What we offer A product line with an established base , in production with universities, public education authorities and corporate academies across Europe and beyond. Genuine end-to-end ownership , from strategy and pricing through to release, without the role being split across a commercial owner and a delivery owner. Access to our researchers , including principal investigators and education methodologists from Constructor Labs, and the ability to route applied research questions into the Labs. Salary and annual bonus tied to the product line's commercial and delivery targets. The band is competitive for a lead product role in DACH or the UK and depends on location and experience. A distribution channel beyond direct sales , through Constructor Labs Solutions and the partner network.

Location: Bulgaria, Sofia Our mission Constructor’s mission is to enable all educational organisations to provide high-quality digital education to 10x people with 10x efficiency. With strong expertise in machine intelligence and data science, Constructor’s all-in-one platform for education and research addresses today’s pressing educational challenges: access inequality, tech clutter, and low engagement of students. Please send your resume in English only. About Constructor Constructor is an international ecosystem spanning education, research and technology. Its education entities include Constructor University, a research university in Bremen, Germany, and partner institutions such as EBAC and Nexford University, together covering degree programs, online education and professional training on several continents. The group employs almost 1,000 people with entities in Europe, America, and Asia. About the Role Constructor is building a global education group: a research university in Bremen (top 400 by THE ranking 2027), online and professional education partners, and more institutions to come through acquisitions, partnerships and new campuses. This role is the analytical core of that build-out. It exists to answer, on a continuing basis, three questions for group leadership: where should Constructor expand, which institutions are worth acquiring or partnering with, and how should our institutions operate. The work is two-sided. You keep a standing pipeline of universities, colleges and school groups under review and bring recommendations on the ones worth pursuing; and you study how the best-run institutions in the sector work, so that their models and practices feed into the strategy of Constructor University and the group's other education entities. The immediate priority is the next campus for Constructor University, which has outgrown its Bremen campus and needs to teach an increasing share of its students outside Germany. You will own the analysis and the recommendations; negotiation and closing are led by the Head of Strategy & Corporate Development, to whom the role reports. You will work directly with group leadership, the management of our education entities and external advisors. Title and level depend on experience.
