Top Remote Senior Level Machine Learning Engineer Jobs in Boston, MA

As a Staff Applied ML Scientist, you will develop and maintain fraud detection models, conduct research on fraud types, and collaborate across teams to drive product development and real-time decision-making.

Lead the development of machine learning systems for Cedar Pay's Personalization Engine, manage ML engineers, and ensure ML model effectiveness.

Build and deploy AI-powered, LLM-based solutions in client environments: implement integrations, develop production-ready code, support cloud deployments, prepare data and prompts, troubleshoot, and collaborate with client and cross-functional teams while documenting and transferring knowledge to enable sustainable production adoption.

Lead architecture and technical vision for integrations that ingest external data (e.g., Salesforce, HubSpot) into Jasper's IQ layer. Design scalable, secure data ingestion, define context primitives, drive cross-team alignment, and deliver staff-level initiatives that improve reliability and AI-driven product quality.

Lead the architecture and hands-on development of an AI/ML mission platform. Responsibilities include designing scalable distributed systems, optimizing edge and cloud performance, leading technical initiatives, establishing engineering standards, mentoring engineers, integrating and deploying AI/ML models, and partnering with defense customers. The role requires strong Kubernetes and cloud-native expertise, technical leadership, production software experience, and eligibility for a Top Secret/SCI clearance.

Own end-to-end matching and ranking systems for out-of-home advertising: design candidate generation and re-ranking models, build and manage data warehouse and pipelines, implement evaluation and monitoring, publish low-latency ranking APIs, and maintain model observability and retraining workflows.

Design and deploy production recommendation and retrieval engines, build data orchestration pipelines for multiple modalities, implement agentic workflow frameworks, and prototype, optimize, and scale models with monitoring, governance, and low-latency SLAs.

Lead architecture and development of advanced perception systems for Level 4 autonomous vehicles. Build multimodal foundation models, synthetic data and sensor simulation capabilities, knowledge-distillation pipelines, and efficient real-time onboard models. Deploy solutions to autonomous vehicle fleets while mentoring engineers and providing technical leadership. The role focuses on object detection, segmentation, tracking, classification, sensor fusion, closed-loop evaluation, and robust generalization across vehicle generations.

Build and improve machine learning systems for ad ranking, relevance, personalization, and optimization. Responsibilities include feature pipelines, model training and evaluation, active learning, LLM-assisted labeling and synthetic data generation, experimentation, and low-latency production inference. The role partners with product, data, and platform teams to improve advertiser performance and user engagement while maintaining reliability, latency, and data quality.

Develop, deploy, and maintain machine learning and deep learning algorithms for biosignal and brain data. Lead the full algorithm lifecycle, including requirements, data curation, modeling, validation, production deployment, documentation, testing, and maintenance. Apply DSP and statistical methods, improve internal ML tooling, introduce advanced model architectures, support regulatory-quality processes, present results to stakeholders, and collaborate with clients, clinicians, neuroscientists, and engineers.
