How to Apply for Senior Security Engineer

at Overstory

🏢 About Overstory

Overstory is a climate tech company using real-time satellite data to reduce wildfire risk and improve grid reliability. Their mission directly combats climate change, making it an impactful place to work for those who want to apply security expertise to environmental challenges. The remote-first culture and focus on innovation attract top talent.

About This Role

As Senior Security Engineer, you'll own the compliance program (SOC 2, ISO 27001) and drive vulnerability management end-to-end. You'll partner with engineering to embed security into architecture and processes, ensuring secure-by-design systems. This role is critical as Overstory scales its satellite data platform to utilities and insurers.

💡 A Day in the Life

Your day might start with a standup to review vulnerability scan results and prioritize fixes with engineering leads. You could then draft a control narrative for an upcoming SOC 2 audit, followed by a design review for a new microservice to ensure secure-by-default patterns. After lunch, you might conduct a tabletop exercise for incident response and end the day documenting a new security policy.

⚠️ Common Mistakes to Avoid

  • Don't focus only on technical skills without showing compliance and audit experience—this role owns the program.
  • Avoid generic answers about 'security best practices' without tying them to Overstory's specific context (cloud, satellite data, utilities).
  • Don't underestimate the importance of communication; this role requires influencing engineers and reporting to leadership.
