About the Role
Join the Spectacles BCI Team at Snap Inc. as a Research Engineer, working on state-of-the-art machine learning for time series data to develop the next generation of wearable device sensing. You will collaborate with global hardware and software teams from our Paris office.
Responsibilities
- Conduct focused, product-related research projects, defining hypotheses and designing experiments using electrophysiological and cognitive data.
- Review relevant literature and translate scientific knowledge into modeling approaches aligned with product needs.
- Build signal-processing and ML pipelines for noisy, real-world time-series sensor data.
- Develop algorithms and ML models for cognitive and physiological decoding using multimodal biological signals captured via wearable devices.
- Collaborate with software and research teams on model development and evaluation, data capture and demos.
- Translate findings into clear recommendations for stakeholders and leadership.
Requirements
- Strong signal-processing fundamentals applied to noisy, real-world biosensor data.
- Proficiency in Python and experience with scientific-computing and ML tools.
- Working knowledge of ML for multivariate time series and multimodal sensor fusion.
- Ability to turn research or product questions into concrete technical plans, experiments, metrics, and deliverables.
- Ability to clearly communicate model limitations, uncertainty, and technical tradeoffs clearly to cross-functional partners.
- Familiarity with AI-assisted engineering workflows.
- Master’s degree in machine learning, computer science, biomedical engineering, computational neuroscience or related fields.
- 3+ years of relevant research or engineering experience developing algorithms or models for time series, biometric, physiological, wearable, behavioral, or multimodal data.
- Hands-on experience with wearable biometrics products or platforms, such as smartwatches, fitness trackers, health trackers, sports-performance wearables, or similar real-world sensing devices.
- PhD in biomedical engineering, computational neuroscience, signal processing with a focus on biosignals or an equivalent record of applied research and engineering impact.
- Experience in electroencephalography, Brain-Computer Interface or cognitive-state estimation.
- Experience designing ML systems for multivariate time series, representation learning, calibration, or domain adaptation.
- Experience with artifact-aware modeling, noisy labels or physiological proxy labels.
- Experience deploying or optimizing ML models for real-life environments
- Experience with agentic AI workflows, skills-based automation, or AI-assisted research.
