Founding Software Engineer (AI / Full Stack)

Role overview Build core software that turns unstructured scientific information into traceable outputs for life sciences teams. The work spans data pipelines, APIs, AI agent systems, and customer-facing applications, with scope to focus more on agentic AI or full-stack product development. You’ll take features from loosely defined needs through production and work closely with internal teams to shape the product.

Responsibilities - Design and deliver features across data pipelines, APIs, and user-facing workflows. - Develop agentic systems for planning, tool use, retrieval, and evaluation using specialized models and scientific data. - Own projects from problem definition through deployment, with attention to reliability, scale, and accuracy. - Use feedback from internal teams to refine product capabilities; some work may involve deployment alongside major pharmaceutical customers. - Improve engineering practices for testing, observability, and security.

Requirements - At least three years of professional software engineering experience, with comfort working across the stack. - Strong software fundamentals and proficiency in Python and TypeScript, or comparable languages. - Experience building LLM or agentic systems, such as retrieval, tool use, evaluation, or agent loops. - A record of shipping useful software with care for reliability and detail; projects or open-source work can demonstrate this. - Comfort working through ambiguity and helping define requirements.

Nice to have - Experience at an early-stage, high-growth startup. - Experience training or fine-tuning machine learning or deep learning models. - Interest or experience in biology, chemistry, or pharmaceuticals. - A computer science or computer engineering degree, or equivalent experience.

Benefits and work setup - Full-time, remote position working East Coast hours; candidates in New York, Boston, or Toronto are preferred. - Compensation includes salary, equity, health coverage, and a 401(k) with employer matching. - Additional offerings include a daily lunch stipend, vacation flexibility, and in-person team retreats.
