Phd Computer Science Jobs in Plainfield, NJ (NOW HIRING)

About Synaptrix Labs Inc.

Synaptrix is on a mission to revolutionize brain-computer interfaces through non-invasive approaches. We believe that the power to diagnose and treat neurological conditions safely, and to expand human potential, will become a reality with the right fusion of deep learning, signal processing, and computational neuroscience.

We're seeking a full time Research Scientist, Artificial Intelligence (PhD) to join our growing team of researchers & engineers. If you're passionate about shaping the future of brain-computer interfaces and excited by the potential of deep learning in neurotechnology, we want to hear from you!

Responsibilities:

• Design, prototype, and optimize state-of-the-art AI systems for neural decoding, including diffusion models, graph neural networks, contrastive/self-supervised frameworks, and transformer-based sequence models.
• Conduct foundational research on neural time-series representation learning: build architectures that extract latent dynamics from EEG, EMG, or related biosignals.
• Develop high-fidelity simulation environments for testing decoding algorithms, incorporating stochastic signal noise and realistic biophysical constraints.
• Scale model training across multi-GPU and multi-node clusters using PyTorch Distributed, DeepSpeed, or JAX/Flax; profile and tune system performance for sub-10 ms inference latency.
• Build and maintain end-to-end research pipelines for large-scale signal datasets, including preprocessing, artifact rejection, and multimodal fusion with video, audio, and IMU data.
• Collaborate with neuroscientists and hardware engineers to integrate learned models into real-time BCI control loops and embedded systems.
• Contribute to core ML infrastructure: experiment tracking, model versioning, dataset lineage, and reproducibility standards.
• Publish at top-tier ML or neurotech venues (NeurIPS, ICLR, Nature Neuro, EMBC) and present findings to the research community.

Minimum Qualifications:

• PhD or equivalent deep technical expertise in Machine Learning, Artificial Intelligence, Computer Science, Computational Neuroscience, or related fields.
• Strong command of PyTorch or JAX, with experience implementing custom training loops, loss functions, and model architectures.
• Proven ability to conduct end-to-end research, from conceptual design to reproducible experiments and evaluation.
• Strong mathematical foundations in linear algebra, probability, optimization, and information theory.
• Experience working with high-dimensional time-series or sensory data (EEG, speech, video, motion capture, etc.).
• Skilled in Python, NumPy, Pandas, and scientific computing workflows; experience with CUDA or low-level GPU debugging is highly valued.
• Demonstrated ability to operate independently on open-ended problems and drive original research with limited supervision.

Preferred Qualifications:

• Deep familiarity with neural signal modeling, neural decoding, or biosignal preprocessing (EEG/MEG/ECoG/EMG).
• Experience designing self-supervised or generative models (diffusion, VAEs, contrastive, masked modeling) for noisy, non-stationary data.
• Background in reinforcement learning, optimal control, or human-in-the-loop systems, especially in continuous domains.
• Publications or preprints in top venues (NeurIPS, ICML, ICLR, CVPR, EMBC, Nature Neuro).
• Familiarity with distributed training, mixed-precision, multi-GPU orchestration, and cloud ML infrastructure (AWS/GCP/Azure).
• Contributions to open-source ML frameworks or custom CUDA kernels.
• Understanding of neural signal acquisition hardware, embedded inference, or edge ML deployment.
• Track record of curiosity-driven, independent research resulting in practical systems or open-source codebases.
