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. BRIEF JOB DESCRIPTION: Contributes hands-on across the applied-research cycle behind Constructor’s education products — surveying recent work, designing and running experiments, analysing results, and prototyping capabilities that apply AI and quantum through an education lens to improve how people teach, learn, and do research. Works closely with research scientists, engineering, and product teams, and helps turn early-stage ideas into working features that feed the AI software development project. Requires 3+ years of research experience — ideally in education technology or applied AI — with a track record of delivering solid, hands-on output in a fast-paced, multidisciplinary setting. MISSION: Do the hands-on experimental work that turns promising ideas into working proof-of-concept code — quickly, and backed by evidence the product and engineering teams can build on. EDUCATION: * Master’s or PhD (or near-completion) in Computer Science, Physics, Mathematics, or a related field — or equivalent applied research experience. Shipped research prototypes, open-source contributions, or publications all count. DUTIES AND RESPONSIBILITIES:  * Scan recent research and turn relevant techniques into prototypes the team can test fast. * Design, implement, and run experiments; analyse results and decide what’s worth taking forward. * Deliver each idea as working proof-of-concept code — clean enough to hand to engineering, not just a written summary. * Help integrate validated research into product features and measure the impact. * Work day to day with research scientists, ML engineers, and product teams to move ideas from notebook to product. QUALIFICATIONS AND EXPERIENCE: * 3+ years of applied research or research-engineering experience — ideally in education technology or applied AI. * Strong Python and PyTorch — able to produce runnable code others can extend, not just specs. * Sound grasp of experiment design, statistics, and result analysis. * Able to read recent papers and reproduce or adapt their methods into working code quickly. * Reproducible, well-documented work using version control (GitLab) and experiment tracking (MLflow). NICE TO HAVE (NOT OBLIGATORY): * Experience taking research prototypes into production or shipped product features. * Publications, preprints, or open-source contributions in AI or related areas. * Exposure to AI-for-education products, or to quantum computing frameworks. WHAT WE OFFER * 💻 Choice of work equipment (e.g., laptop, monitor, etc.) * 🇬🇧 English classes (iTalki – $130 monthly) * ⏰ Flexible schedule (we usually work between 09:00/10:00 and 18:00/19:00 CET or EET) * 👶 Newborn bonus (€500 per child) * 🧠 Patent remuneration * 🌴 Paid leave * 🧑‍💻 Remote work in locations without our offices * Hybrid work in locations with offices (2 days in-office, 3 days remote) Constructor fosters equal opportunity for people of all backgrounds and identities. We are led by a gender-balanced board committed to building a diverse and inclusive organisation where everyone can become their best self. We do not discriminate based on age, disability, gender identity, sexual orientation, ethnicity, race, religion or belief, parental and family status, or other protected characteristics.

BRIEF JOB DESCRIPTION: Builds and maintains the infrastructure and tooling that keeps machine learning systems reliable in production — from designing CI/CD pipelines and model deployment workflows to monitoring performance and managing model lifecycle at scale. The role works closely with ML, backend, and platform teams, contributes to automation frameworks and observability standards, and helps ensure AI models move seamlessly from experimentation to production. Requires 5+ years of MLOps or DevOps engineering experience, with a track record of operating robust ML infrastructure in production-grade environments. MISSION: Make the path from model experiment to reliable production as fast, automated, and observable as possible. EDUCATION: * Bachelor’s degree or higher in Computer Science, Engineering, or a related field — or equivalent practical experience. DUTIES AND RESPONSIBILITIES: * Design and maintain CI/CD pipelines for ML models and services. * Build and operate model deployment, serving, and rollback workflows. * Implement monitoring, observability, and alerting for models in production. * Manage the model lifecycle with MLflow: experiment tracking, versioning, registries, and reproducibility. * Automate infrastructure and partner with ML and platform teams on standards. QUALIFICATIONS & EXPERIENCE: * 5+ years of MLOps or DevOps engineering experience. * Strong with containers and orchestration (Docker, Kubernetes). * Experience with CI/CD (GitLab CI) and infrastructure-as-code (Terraform or similar). * Hands-on with a major cloud platform (Azure, AWS, or GCP). * Hands-on experience with MLflow for experiment tracking and model registry. * Familiarity with ML frameworks (PyTorch), workflow orchestration (Kubeflow or similar), and monitoring stacks. NICE TO HAVE (NOT OBLIGATORY): * Experience serving LLMs or large models in production. * Knowledge of feature stores and data pipeline tooling. * Cost and latency optimisation for model serving.
