Senior Engineer, Platform Security and Reliability

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.

Kairos Power is looking for a Senior Platform Security and Reliability 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 own the security baseline and the reliability posture of the cloud and high-performance computing platforms that engineering teams depend on, and you will build the controls, automation, and recovery mechanisms that keep those platforms both defensible and dependable.

You will set technical direction for platform security controls across AWS and Google Cloud, for identity and secrets management, for machine image security, for network security, and for observability architecture. You will lead the migration of legacy cloud workloads and the retirement of duplicative services, and you will own the cost visibility and resource guardrails that keep cloud and high-performance computing spend predictable. You will lead response to both availability and security incidents, and communicate clearly with the engineers and stakeholders who depend on these services. 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 becoming the trusted technical owner of platform security and reliability, with systems that can be operated and maintained by engineers other than their original author.

Security baseline and platform controls

• Define, implement, and maintain the security baseline for cloud and Linux platforms, including operating system hardening, benchmark configuration, and secure defaults for new environments.
