About the Role
As a Senior Machine Learning Engineer, you will harness extensive experience in machine learning and data science to drive innovation and performance at Constellation. You will contribute to the design and deployment of advanced AI systems that meet high standards of compliance and precision. Your work will involve exploring complex datasets, developing sophisticated ML models, and making impactful architectural decisions to optimize performance at scale. You will also mentor team members, guide project directions, and enhance our platforms functionality and quality. We seek candidates with both technical expertise and integrity to deliver solutions aligned with our mission. Youll have the opportunity to engage in cross-functional projects, contribute to roadmap decisions, and grow into leadership roles as we continue to expand. Role Responsibilities
Collaborate with product teams and data specialists to architect and build advanced generative AI systems optimized for regulated industries. Drive Agentic AI capabilities: build agent-based systems that reason, retrieve, validate, and act autonomously, supporting prompt chaining, tool usage, and evaluation feedback loops. Lead the setup and management of infrastructure for diverse OSS AI models, ensuring robust scalability and production-readiness. Design, implement, and maintain efficient ETL processes with Data Engineering to optimize data pipelines for real-time ML applications. Innovate and recommend solutions to enhance Constellations technology portfolio with explainable and ethical AI frameworks that meet regulatory requirements. Manage project priorities, deadlines, and deliverables in line with rapid growth objectives. Maintain and manage code within a Git repository, adhering to best practices for version control and documentation. Mentor and guide the Data Team, fostering professional growth and alignment with Constellations high standards. Job Requirements
7+ years of professional experience in machine learning, data science, or data engineering, with deep expertise in TensorFlow and PyTorch. Proficiency with ML platforms such as Dataiku, SageMaker, and MLflow; experience deploying large-scale models in production. Extensive knowledge of NLP techniques (Embeddings, Encoders, NER, Topic Modeling); experience fine-tuning transformer-based models and using Hugging Face is preferred. Strong programming skills in Python and SQL; ability to work with large datasets and complex data models. Experience with AWS services (Lambda, EC2, Glue, SageMaker) and scalable ML infrastructure. Experience in deep learning, especially fine-tuning Large Language Models and Retrieval-Augmented Generation; familiarity with vector databases (e.g., Pinecone, Weaviate) is a plus. Familiarity with graph databases (e.g., Neo4j) and applying these to compliance-focused AI use cases. Excellent technical documentation and communication skills; ability to explain complex concepts to technical and non-technical stakeholders. Strong interest in compliance and regulatory frameworks in AI (GDPR, HIPAA, or similar) is highly desirable. Benefits
