Description

About Pacific Fusion Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy. We are rapidly designing and building a pulser-driven inertial fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems. Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders . 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. What You'll Do 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 Partner with top fusion scientists to hone data-driven decision making processes for achieving major objectives like facility gain in the fastest time possible Understand the technical decision making needs and drive decisions and implementation on how to analyze and visualize massive datasets Lead by example in excellence in execution, delivering well-designed software systems and driving company culture towards rigorous, expeditious, and risk-conscious execution What You Bring 7+ years of experience expertise in developing interactive web apps with React Strong experience with data streaming and messaging systems Strong database systems knowledge Strong experience in back end application development Competency with CI/CD workflows and tooling Excellent interpersonal skills to carefully understand system requirements and efficiently enable end users to meet business objectives Track record of driving strategic decisions with high volume yet uncertain data Bonus Points For Experience working in hard tech industries such as: fusion, aerospace, EVs, energy, robotics Experience working closely with PhD scientists and R&D technology organizations Familiarity with database systems used for quantitative data Experience growing and leading teams in a fast paced environment Pay Range: $138,000 — $207,000 USD Total Compensation & Benefits for Eligible Employees Industry-competitive salary Equity plan 6% employer 401k matching Generous paid time off (including sick leave, vacation, paid family leave) Medical, Dental, and Vision insurance Actual base salary offered will be determined by: experience, skills, and work location.
