Why This Role Matters

Pacific Fusion will continue to generate quantitative data at an exponentially increasing rate as we evolve from pulser hardware prototypes to mass pulser component production to continuous operations at the Demonstration System. Curation of this data for efficient analysis, consumption, and action is critical to rapid execution. As Senior Full Stack Developer, you will architect and develop data acquisition systems and web front ends for Pacific Fusion’s growing need for full stack applications for recipe management, data acquisition, and data processing. This includes architecting and developing databases and database schemas, developing apis to access data, and front end react applications to manage and present data for the pulser factory and, later, the Demonstration System.

Design and implement the front end and user experience for the pulser factory hardware testing systems, reducing the time it takes to build, commission, and deliver over one hundred shipping-container sized pulser modules

Design and Create Figma or equivalent demos for UIs to get consensus for look and feel of the UI by stakeholders

Define database schemas and deploy the database systems to store heterogenous data from controls systems, hardware testing equipment, and eventually experimental diagnostics on the Demonstration System

Architect the data flow and user experience for Pacific Fusion’s Demonstration System, aggregating disparate data from dozens of diagnostics into actionable distillations for the scientific staff. Build and lead a team to deliver this mission critical system

Relentlessly accelerate the software-driven data lifecycle on the demonstration system, reducing the time from experiment to analysis to decision
