Senior Member of Technical Staff (Applied AI)

Solstice is redefining how life sciences organizations commercialize therapeutics by building a commercial engine that enables pharmaceutical marketers to launch campaigns at 100x the speed. The Senior Applied AI Engineer will own the technical direction of AI systems across retrieval, generation, verification, evaluation, and production operations, while influencing product strategy, technical hiring, and market positioning.

Responsibilities:

• You will work closely with VP of Engineering Jay, and co-founders Aris and Yiwen, influencing product strategy, technical hiring, and our market positioning
• High-craft output: Our clients demand work with polish, not "AI slop." Pharma assets like emails, banners, slides and leave-behinds require both visual and textual excellence. ISI must be prominent, brand systems must endure, and hierarchy and typography must survive generation. Our job isn't just compliance. It's making sure assets don't get quietly rewritten by marketers
• Connecting content to outcomes: Passing MLR review means a piece can ship, but not that it worked. We'll connect generated assets to real-world performance, including engagement, HCP response and scripts written, and use that data to improve future output
• Evaluation where ground truth is slow: Determining compliance is slow, coming back as reviewer redlines in inconsistent formats. Developing offline metrics that track downstream MLR pass rate is critical
• Claim-level attribution: True grounding means every sentence can be traced back to a specific, defensible source. Our proprietary corpora span prescribing information, clinical data, approved assets, style guides and claim libraries, and provenance must be preserved through generation
• ML Ops and behavioral regression: Full CI/CD for ML, versioning, automated testing, monitoring, and the harder under-the-hood work. Upgrades shift output in ways easy stats can miss, and tail risks matter most. Ongoing vigilance is required
