Solstice Labs
Commercial Engagement Associate
NewOther
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.
Rapid growth: Over the past year, we have been working with some of the top life sciences manufacturers and are working with over 50+ pharma brands.
Frontiers of technology: 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 to our solution to better define the possibilities of pharmaceutical marketing.
Top-tier investors: 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.
Building anything great requires commitment and dedication. We’re looking for someone who has the fire to prove others wrong
We’re building Solstice to automate compliant, reference-backed pharma marketing. As a founding full-stack engineer, you’ll own core parts of the application stack, designing APIs, background workflows, and deployment pipelines, and you’ll be responsible for packaging and shipping LLM “agents” to production. Beyond development, you will be collaborating closely with co-founders Yiwen and Aris on all facets of the startup as we grow Solstice in the coming years as we ship fast, safe, and observable systems.
Backend services & APIs: Build and harden FastAPI services; design clean interfaces for ingestion, retrieval, annotation, and compliance checks.
Workers & queues: Stand up a reliable background job platform with Celery + Redis (scheduling, retries, idempotency, backoff, result stores).
Agent deployment: Package LLM/RAG agents (e.g., LangGraph/LangChain) into production service.
Cloud & infra: Ship to AWS, manage secrets, networking, autoscaling, and cost controls.
Integrations: Building robust, enterprise integrations with cloud platforms such as Veeva Promomats, Adobe, and Figma.
Pipelines & files: Orchestrate file processing (PDFs, images), OCR, embedding pipelines, and metadata enrichment at scale (S3-first design).
Data layer: Model clean schemas and access patterns for Postgres; use Redis for caching and rate-limiting; integrate vector DBs (Pinecone).
Frontend touchpoints: Contribute to our Next.js frontend where necessary.
