Sr. Fullstack Product Engineer - (Frontend Focus)

Salt AI is building the governed execution platform for AI work that has to be real: deployable, auditable, permission-aware, and reliable enough for regulated industries.

Our customers are doing work where “the demo looked cool” is not enough. In life sciences, that can mean RNA-targeted drug discovery, combinatorial chemistry, clinical-trial-adjacent research, and scientific workflows that need traceability, reproducibility, and trust. In financial services, healthcare, legal, and government, it means sensitive data, private infrastructure, and AI systems that have to be controlled rather than merely impressive.

We are looking for a Senior Full Stack Product Engineer who can help turn that platform into something customers can actually build on: software that feels considered, powerful, fast, trustworthy, and unusually good for the complexity underneath.

This role leans frontend and customer experience. You should go deep on React, TypeScript, design systems, motion, interaction design, dense information interfaces, and the craft of making complex software feel powerful, calm, and beautiful. But the scope is still fullstack. You are not just implementing screens. You are responsible for the full stack of the customer experience: the interface, the interaction details, the runtime behavior, the APIs, the data contracts, the failure states, and the quality bar of the thing a customer actually uses.

The Role

This is a fullstack product engineering role for someone who likes deep systems, clean abstractions, and product surfaces that make hard infrastructure feel usable.

You will work across the platform layer and the application layer: workflow execution, agent orchestration, pipeline-as-tool contracts, customer data access, retrieval, permissions, observability, and the UI surfaces that expose those capabilities to real users. Some weeks the important work will be a React interface that makes a complex decision legible. Some wee...
