About us:Planner 5D is a general hub for home design, uniting over 100+ million users in 230 territories around our planet (yes, we have 2 users connecting from Antarctica each month!). Our platform simplifies the home renovation process from concept to execution, and this process has never been more straightforward with our cutting-edge software. You don't need to be a professional designer to enhance your home or workspace. We are dedicated to streamlining the design experience, making the customization of dream homes accessible to everyone.Our cross-platform presence spans Web, iOS, Android, Windows, and MacOS, ensuring seamless synchronization for our users. Planner 5D is more than just software; it's a vibrant community of enthusiastic and product-oriented professionals. From diverse backgrounds, our team collaborates across time zones, fueled by a shared passion to revolutionize the home design market.We are constantly looking for like-minded talent eager to take ownership and drive innovation within our expanding suite of tools. Join us in shaping the future of home design.We are searching for an AI / Machine Learning Researcher to join our AI team and focus on applied research for real-world product challenges. You will work with raw data, explore new approaches, formulate and test hypotheses, and build prototypes and MVP solutions that can later become production features within the Planner 5D platform.You will:Conduct applied research in AI/ML to solve real-world problems related to home design, 2D/3D data, and visual understandingWork with raw and unstructured data (images, 3D point clouds, text, video) to identify useful signals and formulate research directionsGenerate and test hypotheses through experiments, modeling, and data analysisDesign and implement prototypes and MVP solutions, validating ideas before production implementationTrain, evaluate,



and iterate on machine learning and deep learning modelsContribute to the development of AI-driven features, including computer vision systems and AI agentsCollaborate with engineers to translate research prototypes into production-ready solutionsProvide algorithm-level support for deployed models, improving and adapting them as new data or requirements emergeRequirements4+ years of experience in AI/ML research or applied machine learningStrong background in mathematics and computer science, including statistics, optimization, linear algebra, and algorithmsSolid understanding of machine learning and deep learning methodsExperience working with real-world datasets, including data exploration, cleaning, feature extraction, and experimental validationProficiency in Python and common scientific/ML libraries (NumPy, SciPy, Pandas, etc.)Experience with deep learning frameworks such as TensorFlow or PyTorchFamiliarity with computer vision or multimodal AI (images, video, 3D data such as point clouds and meshes)Ability to independently formulate research hypotheses, design experiments, and evaluate resultsStrong analytical thinking and ability to solve complex problems with limited prior solutionsNice to haveExperience with 3D data processing (point clouds, meshes, spatial data)Experience building or experimenting with AI agents or LLM-based systemsExperience training and fine-tuning neural networksInterest in geometry, graph theory, or computational geometryWhat we offer:Great work environment that balances freedom and responsibilityOur team is made up of friendly and passionate enthusiasts who are eager to help and share their knowledgeWe believe in work-life balance, so you'll receive around 30+ days of paid holidays per yearCompany computer equipment by requestEducation courses for our team members, and we're willing to allocate funds toward your training expensesEnglish classes on our corporate platformOffline company events in Lithuania and online team-buildingUnlimited free Planner5D subscriptions
