Data & AI Platform Engineer

The Digital Solutions team at Brown and Caldwell (BC) is seeking a Data & AI Platform Engineer to strengthen our cloud platform, deployment, and AI/data infrastructure capabilities. This role bridges traditional

MLOpsand data platform engineering with the demands of production-grade AI including retrieval-augmented generation (RAG) pipelines, multi-agent orchestration, andLLMOpsto support the full lifecycle of analytics, modeling, and AI-enabled delivery workflows.

We are looking for someone with depth in platform engineering, Dev Ops/MLOps, and cloud infrastructure, who can also operationalize

AI systems with rigor. You will partner closely with data scientists, AI engineers, cloud architects, and domain SMEs to deliver scalable, maintainable, and auditable solutions across environmental and water-resources projects.

The Data & AI Platform Engineer role will design, develop, and maintain data pipelines and architectures that enable effective data integration, storage, and analysis. The role’s responsibilities will include data modeling, ETL development, and performance tuning of data systems. The role will also be involved in troubleshooting and resolving data-related issues with a focus on data quality and accessibility. Additionally, the role willbe responsible for architecting pipelines in compliance with BC and clients’ data security and industry standards.

• Design, create and maintain data pipelines to collect, clean, transform, and load data from various sources, including sensor data, historical records, and geospatial information to facilitate data warehousing.
• Collaborate with interdisciplinary teams of environmental engineers, data scientists, and software developers to understand data requirements and develop scalable data solutions.
• Participate in the design of and execute the creation and management of data warehouses, data lakes, and databases to ensure efficient data storage, retrieval, and management.
• Develop, deploy, execute, and monitor ETL (Extract, Transform, Load) processes to support data analysis, visualization, and machine learning model training.
• Develop and maintain data models and engage in SQL database management and querying with the objective of efficiently handling stored data.
• Design and execute testing plans for data pipeline and data warehousing implementation efforts.
• Implement processes for improving data quality and managing data governance for enhanced reliability and accessibility.
• Collaborate with IT infrastructure and cybersecurity teams to implement and operate data pipelines within approved data infrastructure, performance, and security guidelines.
• Design and execute processing tasks using Python and maintain up-to-date understanding of big data processing frameworks.
• Perform regular data audits and updates to ensure high level of data accuracy and integrity.
• Flexibility to adapt and execute various additional assignments based on evolving needs.
• May provide mentorship, guidance, support, and knowledge-sharing to help less experienced team members develop their skills and grow within their roles.

• Understanding in building and optimizing data pipelines, architectures, and data sets.
• Strong working SQL knowledge and skills in implementing and managing relational databases.
• Proficient in ETL processes creation and management and techniques for data cleaning and validation.
• Proficient in Python and other scripting languages applicable for data engineering.
• Proficient with best practices for writing clean, maintainable, and scalable code while applying software engineering best practices including use of version control systems (e.g., Git).
• Demonstrated abilities with data warehousing solutions, data lake solutions, and cloud platforms.

• Typically, a minimum of 5 years of data engineering or related experience.
• Typically certified in BC's SMS Framework and progressing through the SMS competencies.

• Hands‑on experience supporting production LLM‑ or RAG‑based systems in a platform, data, or MLOps capacity, including retrieval pipelines, vector search and embeddings, document chunking strategies, and…
