Praxis Solutions, Inc
Overview
Direct message the job poster from Praxis Solutions, Inc Delivering custom, AI-driven solutions across the financial industry
Praxis is a cutting-edge AI consulting and implementation firm that partners with Asset Managers, Wealth Managers (broker-dealers, RIAs), FinTechs, Real Estate investors, Insurance companies and Banks to unlock the full potential of AI across investment research, compliance, client onboarding, and beyond. We specialize in crafting private, secure, and scalable AI solutions that deliver real value fast. From transforming unstructured documents into investment-grade insights to powering next-generation client experiences with custom large language models (LLMs), we enable data to function more efficiently and swiftly. If you excel at the intersection of data architecture, AI infrastructure, and financial systems—and aspire to contribute to building transformative technology from the ground up—this is where you truly belong. We welcome US and global experience—we value diverse perspectives that enrich our approach to building scalable, secure, and innovative AI systems. We are actively seeking a dedicated AI Scientist, specializing in large-scale language models and advanced AI architectures, to join our team. If you’re passionate about developing safe, scalable, and responsible AI solutions to drive financial transformation, we’d love to hear from you. Role Overview
As an AI Scientist at Praxis Solutions, you’ll play a key role across the AI solution lifecycle—from research and ideation to implementation, deployment, monitoring, and ethical oversight. You will design, train, and refine LLMs, multimodal AI models, and reinforcement learning systems, while ensuring responsible AI usage in high-stakes financial applications. Key Responsibilities
Design, train, and optimize Transformer-based and multimodal models, both from scratch and through fine-tuning. Employ tools and frameworks (e.g., Hugging Face Transformers, PyTorch, TensorFlow) for scalable experimentation and deployment. Develop strategies for model safety and robustness, including bias mitigation, hallucination control, memory editing, and responsible AI design practices. Innovate in research areas such as RAG (retrieval-augmented generation), multi-agent systems, and RLHF (reinforcement learning with human feedback). Collaborate with data scientists, engineers, and product teams to deliver secure, high‑performance AI systems. Stay at the forefront of AI by tracking emerging research and contributing to publications and conferences. Validate models with rigorous testing, monitoring, explainability, and reliability metrics. Must-Have Qualifications
Master’s degree or PhD in Computer Science, Machine Learning, AI, or a related field Deep expertise with transformer-based architectures (LLMs such as GPT, BERT, RoBERTa, multimodal models) Proficiency in Python and ML frameworks (PyTorch, TensorFlow) Direct experience in training, fine-tuning, and deploying LLMs in production environments Solid grounding in RLHF, bias/fairness in AI, and model safety auditing Strong research background with the ability to transform academic innovation into practical applications Excellent problem-solving, analytical, and communication skills Nice-to-Have Qualifications
Published research in AI/ML (peer-reviewed conferences or journals) Experience with cloud AI platforms (AWS / GCP / Azure) and MLOps tools for production-scale deployment Familiarity with safety monitoring frameworks, observability dashboards, and compliance standards Exposure to financial applications of AI, including quantitative methods, trading systems, or financial forecasting Demonstrated experience in mentorship, public speaking, or technical training What We Offer
Competitive salary + equity in a high-growth AI firm Health, dental, and vision benefits Uncapped PTO Flexible work hours and a remote-friendly culture Opportunity to work with a passionate team on high-impact, AI-first projects in financial services How to Apply
