Job summary

Lucentive is seeking an experienced engineer to own the shared AI systems layer used by multiple products. You will shape runtime behavior across tools, memory, retrieval, and reasoning and define patterns for provider changes that keep architecture durable as teams and products grow.

You will design and maintain the orchestration runtime, build provider interfaces for flexible model changes, and own regression testing and drift detection.

Qualifications

• Experience building AI systems and production infrastructure used by multiple products or teams.
• Strong software engineering discipline with typed, production-grade implementation.
• Experience designing abstractions that endure provider changes.
• Ability to set technical direction and build infrastructure other engineers can adopt independently.
• Practical evaluation experience with tests that catch regressions and inform release decisions.
• English fluency for engineering collaboration and written review.

Responsibilities

• Design and maintain the orchestration runtime that combines tools, memory, retrieval, and reasoning.
• Create a provider interface that supports model changes or mixed-provider strategies without requiring product-level rewrites.
• Own shared evaluations, including reference data, regression checks, and drift detection.
• Define reusable engineering patterns and decide when engagement-specific pipelines should become shared infrastructure.
• Review architecture choices across projects and keep them aligned as they scale.
• Maintain production observability and turn system contracts into clear interfaces for downstream teams.
