As a Cybersecurity Software Engineer focused on product security, you will ensure that the firmware, software, and server infrastructure driving our fusion machines are resilient against attack. You’ll work closely with firmware, software, and infrastructure engineers to embed security into every stage of the development lifecycle—reviewing designs, auditing code and dependencies, and integrating security checks into CI/CD pipelines. You’ll lead initiatives in encryption, secrets management, and secure authentication to protect sensitive machine operations.
Beyond building defenses, you’ll champion security best practices across the organization, providing both the tools and the guidance to enable engineers to move quickly without sacrificing safety. This role is ideal for someone who wants to blend deep cybersecurity expertise with hands-on engineering to safeguard one of the most advanced energy technologies being built today. This is an onsite role that reports directly to the Lead Electrical Engineer at our Everett, WA office.
You Will:
Review firmware, software, and infrastructure designs to identify and mitigate security risks before implementation
Advocate for and implement security best practices across engineering, such as encryption, key rotation, and secure authentication
Deploy and manage application security tools (e.g., Snyk, Trivy, Docker image scanners) to audit dependencies, supply chain risks, and vulnerabilities
Own the definition and enforcement of product-level secrets management and credential handling
Lead initiatives in software and firmware hardening for production systems, ensuring resilience against potential adversarial attacks
Work with firmware, software, and infrastructure engineers to embed security into CI/CD pipelines and development workflows
Create and maintain internal guidelines for secure coding practices and data classification
Contribute to building institutional trust by ensuring our software and firmware meet high standards of security, reliability, and compliance
Serve as the voice of product security in design reviews, code reviews, and cross-functional engineering efforts
Required Skills:
Strong Linux systems knowledge, including security hardening and permissions management
Proficiency with Git-based workflows and secure software delivery practices
Solid understanding of modern encryption standards (TLS, AES, RSA, ECC) and key management practices
