Member of Technical Staff (QA Engineer - Agentic Systems) at Solstice USX

<h2><strong>Why you should join us</strong></h2><p style="min-height:1.5em">Solstice is redefining how life sciences organizations commercialize their therapeutics. We are building a commercial engine that allows pharmaceutical marketers to launch campaigns at 100x the speed.</p><p style="min-height:1.5em"><strong>Rapid growth:</strong> Over the past year, we have been working with some of the world’s top life sciences manufacturers including Pfizer and AstraZeneca and are working with over 50+ pharma brands.</p><p style="min-height:1.5em"><strong>Frontiers of technology:</strong> We're building applications and rapidly iterating technical approaches at the frontiers of AI, experimenting with LLMs and new frameworks. We are incorporating new, advanced frameworks into our solution to better define the possibilities of pharmaceutical marketing.</p><p style="min-height:1.5em"><strong>Top-tier investors:</strong> We've raised from investors like Transformation Capital, Twelve Below, Virtue and the founders of Datavant, Commure, and Paradigm to supercharge our growth and build an elite team of engineers and operators.</p><p style="min-height:1.5em">Building anything great requires commitment and dedication. We're looking for someone who has the fire to prove others wrong.</p><p style="min-height:1.5em"></p><h2><strong>About the role</strong></h2><p style="min-height:1.5em">We're hiring our first dedicated QA lead to own quality for the AI that powers Solstice. Our platform generates regulated pharmaceutical marketing content for the brands we work with, so when the output is wrong, say an unsupported claim or a missing safety disclosure, it becomes a real compliance problem and not just a bug to file.</p><p style="min-height:1.5em">What makes this hard is that the system is probabilistic. The same prompt can return different answers, "correct" is often a judgment call, and the exact-match assertions that traditional QA relies on don't apply. We need someone who can measure quality anyway and build the evals that catch regressions before a client does, so the rest of the team can keep moving quickly.</p><p style="min-height:1.5em">This role is about more than the models, though. Just as much of what keeps customers happy is ordinary product reliability: that the app does what it should, and that a frontend tweak or a new feature doesn't quietly break something in production. You'll own that side too, with a solid end-to-end suite in Playwright and the hands-on manual testing that catches what automation misses.</p><p style="min-height:1.5em">This is a senior, hands-on engineering job. Most of your time goes to writing code and building test infrastructure, but you'll also dig into manual testing whenever that's the fastest way to find a problem. Your work will reach across the whole product, from the backend services to the frontend customers use every day.</p><p style="min-height:1.5em"></p><h2><strong>What you'll be working on</strong></h2><ul style=
