Senior AI Product Engineer

Citian develops software for transportation and infrastructure systems. The Senior AI Product Engineer turns agency problems into reliable AI-enabled product capabilities, working across product, design, engineering, and data science to evaluate, build, and operate them in production.

Responsibilities:

• Work with product, design, Customer Success and data science to understand agency problems, and help find and validate where AI adds value and where it doesn't
• Design, build and ship AI-enabled capabilities within our products, end to end, from data access to the application
• Fit model-based features into our existing software and data architecture without building unnecessary AI infrastructure, and record the key design decisions
• Design and maintain evaluations for AI features, including correctness, grounding, authorization, appropriate abstention and regression detection. Establish practical release criteria and use production feedback to improve quality
• Make AI-generated results traceable to their underlying data, queries and assumptions
• Enforce customer isolation and each user's own permissions, including when tools retrieve or query data, and guard against prompt injection
• Own features in production: latency, cost, reliability, monitoring, failure modes and incident response
• Choose the right technique for each problem (prompting, tool use, retrieval, text-to-SQL, fine-tuning or no AI at all), weighing accuracy, cost, speed and time to market
