Nice to have: * Comfort working with hardware APIs (e.g., vendor SDKs, REST/gRPC services, serial/fieldbus interfaces) from Python or similar, and reasoning about timing, synchronization, and error handling. * Experience with multi-modal data fusion (combining spectral, imaging, and process data) or related techniques in domains such as autonomous systems, medical imaging, or industrial inspection. * Background in plasma physics, optical diagnostics, materials science, or related fields - or strong interest and ability to learn these areas quickly. * Experience deploying models into edge or real-time systems with latency and reliability constraints. * Familiarity with lab automation or experiment orchestration tools (e.g., custom Python control scripts, LabVIEW, PLC/SCADA, or equivalent), and interest in building lightweight, code-driven alternatives. * Experience with experiment tracking, MLOps, or data-centric tooling (e.g., MLFlow, Weights & Biases, DVC) and modern software engineering practices (Git, code reviews, CI/CD). * Prior work with battery manufacturing, roll-to-roll processes, or high-temperature coatings (e.g., turbine components) is a strong plus. ## Description We're looking for a Senior Scientist, Algorithms & Data Products to join our core R&D team, working at the heart of our manufacturing intelligence platform - not in a commercial analytics role. You'll turn rich plasma sensor signals into trusted metrics and models and to build the automation that powers our next generation of experiments. In this role you will: * Design and build algorithms that map multi-modal sensor data (optical emission spectra, electrical signals, thermal/other sensors, process context) into robust "material fingerprints" and properties. * Work with systems, plasma, and applications engineers to marry hardware and software: designing and automating experiment protocols for our benchtop, inline roll-to-roll, and robotic piece-to-piece platforms. * Shape our first generation of models and metrics for battery electrodes and ceramic barrier coatings, directly influencing what customers see and trust. This is a high-impact, hands-on R&D role at the core of SirenOpt's technology stack, shaping how we design, run, and learn from our experiments. What You'll Do * Own end to end modeling pipelines from raw sensor data to customer facing metrics and alerts. * Develop multi modal representations of plasma-material interactions that generalize across different materials, geometries, and processes. * Design and implement automated experimental protocols (parameter sweeps, DOE campaigns, calibration routines) that coordinate plasma hardware, motion/robotics, sensing, and data capture. * Work with embedded, controls, and software engineers to design deployment architectures across edge devices, host controllers, and cloud systems. * Define performance metrics, validation strategies, and monitoring for models running in benchtop products and pilot manufacturing lines. * Own the trustworthiness of our data - interrogate raw and derived data for instrument artifacts, drift and silent pipeline failures, and build the checks that catch a bad result before it reaches a model, a customer metric, a disclosure, or a paper. ## Related Videos - [Python Data Visualization @ Deepnote (w/ PyViz overview)](https://www.wearedevelopers.com/videos/113-python-data-visualization-deepnote-w-pyviz-overview) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Vectorize all the things!
