Assist in developing and deploying AI/ML solutions, including agentic frameworks, RAG pipelines, LLM applications, personalization systems, and cloud-based ML platforms. Support model optimization, data workflows, ontology modeling, and Palantir Foundry/AIP implementations. Collaborate with research, engineering, product, and business teams to integrate generative AI into products, improve search and recommendations, and maintain secure, scalable reference architectures.

Supports quantitative research and data science projects involving financial, insurance, and alternative datasets. Responsibilities include data preparation, exploratory analysis, statistical and machine learning modeling, algorithm implementation in Python, forecasting, optimization, conversational AI, model validation, documentation, and presenting findings. The intern collaborates with senior researchers while applying responsible AI, transparency, safety, and regulatory standards.

Build and evaluate production AI systems across predictive modeling, forecasting, optimization, reinforcement learning, and LLM applications. Conduct exploratory data analysis, feature engineering, experimentation, and rigorous model evaluation. Collaborate with data scientists, ML engineers, business stakeholders, and operating teams to translate workflows into deployed solutions. Explore emerging AI tools, document work, report project performance, and support responsible AI governance.

Build and operate agentic AI products end to end, including LangGraph-based workflows, LLM evaluation systems, React interfaces, Java Spring Boot and Python services, REST APIs, iOS features, and distributed cloud infrastructure. Lead system design, testing, performance improvements, and engineering standards while mentoring junior engineers. Collaborate with product and design teams to deliver reliable multi-tenant applications and continuously improve agent quality through regression testing, trajectory scoring, and evaluation-driven development.

You will build agentic AI products across web, backend, and iOS, owning features end-to-end and mentoring junior teammates.

Lead the design and implementation of technical solutions, translating business requirements into actionable architectures while collaborating with clients and internal teams.

The Senior Software Engineer will design and build full-stack applications using React and Java, ensuring scalable systems, mentoring juniors, and collaborating with cross-functional teams.

Ownership of hardened batch pipelines, feature infrastructure, model governance (versioning, lineage, reproducibility), and third-party data integrations. Implement MLOps tooling for consistent, auditable deployments, keep systems audit-ready, and integrate surveillance, KYC, screening, market, and blockchain data sources in a regulated environment.

Contribute to development, deployment, and monitoring of production ML models; perform data cleaning, analysis, and visualization; collaborate with cross-functional teams to deliver AI-driven business solutions and communicate insights to stakeholders.

Lead end-to-end design and deployment of production AI systems for marketing, sales, and operations. Build predictive models, experimentation and optimization frameworks, and LLM-powered applications (RAG, orchestration, structured extraction). Translate business workflows into production systems, partner with engineers to harden solutions, own client relationships, and mentor data scientists and engineers.
