Senior Engineer, Scientific Software and Developer Platform, Modeling and Simulation

The posting, as Kairos Power wrote it

Company Overview

Kairos Power is a new nuclear energy technology and engineering company whose mission is to enable the world’s transition to clean energy, with the ultimate goal to dramatically improve people’s quality of life while protecting the environment. This goal will be accomplished through the commercialization of the fluoride-salt-cooled, high-temperature reactor (FHR) that can be deployed with robust safety, affordable costs, and flexible operation to accommodate the expansion of variable renewables.

Job Summary

Kairos Power is looking for a Senior Scientific Software and Developer Platform Engineer to work within a small software and infrastructure team that supports the needs of our design, research, and development organizations. This is a hands-on individual contributor role. You will architect and build the scientific software, developer tooling, and delivery systems that nuclear engineers and computational scientists use to design and analyze nuclear power systems.

The work spans Python and C++ development, computational modeling, build and packaging systems, reproducible artifact delivery, CI/CD, containerization, software quality assurance, and high-performance computing workflows. You will set software architecture direction, establish the design and maintainability standards the group works to, and raise engineering practice through design review, code review, and mentoring. The group favors simple, proportionate designs assembled from standard, well-supported technologies, and this role is expected to be a leading voice for that standard. Success means writing and shaping software that engineers other than its original author can operate, extend, and maintain.

Responsibilities

Scientific and engineering software

• Design, implement, test, and maintain scientific and engineering software in Python and C++, including the implementation of computational modeling methods and numerical algorithms.
• Own software architecture for internally developed engineering tools, selecting data structures, interfaces, and algorithms that match the actual problem rather than an anticipated one.
• Profile and optimize performance where a measurable requirement justifies the work, and document the resulting characteristics.
• Collaborate with nuclear and other non-software engineers to define software projects based on their needs for tools that support the primary mission of the company.

Build, packaging, and artifact delivery

• Own CI/CD for internally developed software using GitHub Actions or comparable systems, including automated testing, quality gates, and controlled release.
• Build reproducible build and packaging pipelines for Python packages, Conda environments, and C++ binaries and libraries, including compiler and dependency management.
• Own artifact publication and versioning, so that consumers can determine exactly what they are running and reproduce it later.
• Diagnose and resolve compilation, dependency,
