About The Position

We’re looking for a Senior Security Engineer to help shape and scale the security foundation of Macroscope’s platform. You’ll play a key role in designing and implementing security architecture, controls, and secure-by-default practices across the distributed systems, infrastructure, and APIs that power our core product. You’ll lead projects focused on protecting customer data, hardening our production environment, and raising the security bar across everything we ship—ensuring our systems can evolve alongside customer demand while maintaining enterprise-grade security. You’ll also partner closely with the rest of the engineering team to establish best practices in identity and access management, cloud security, secure CI/CD, secrets management, vulnerability management, and production monitoring. As part of our small team, you’ll work directly with the founders, engineers, and designer to make architectural decisions that will define the trajectory of our product and company. This is a hands-on role for someone who’s excited to build. You are driven by shipping secure systems and helping the team move fast without compromising on safety.
