# Safety Analysis Engineer

Alva is seeking a Principal Safety Analysis Engineer to help build the thermal-hydraulic methods that underpin power uprate programs across the pressurized water reactor fleet. This is a methods development role at its core: you will develop, validate, challenge, and improve the analysis approaches used to determine safety margin, establish technical credibility, and support licensing decisions. The methods developed by this team will be foundational in determining the scale of uprate that can be achieved on each project and in driving those projects through licensing. Why this role is different You will have meaningful ownership of a safety analysis capability being developed from the ground up, without being constrained by a legacy structure. See a direct connection between methods and plant impact. Your technical decisions will help determine where real thermal-hydraulic margin exists, what limits an uprate, and how much additional power can be credibly pursued. Help shape Alva at an early stage. The role offers genuine influence over the safety analysis program and the broader company, with the ability to move quickly, challenge assumptions, and introduce better ways of working
