Principal Software Engineer - OnPrem

At Cerby we believe security is everyone’s business.  Collaborating across your apps doesn’t need to be chaos.  We are a mission-critical cybersecurity company that empowers your teams to operate securely and control their apps completely.  We’ve built our product on the idea that teams deserve autonomy over their work apps.  It turns out that why they are guaranteed a choice, security comes naturally.

More than 50% of all technology is spent outside of centralized IT organizations.  Individual business units are taking their technology destiny into their own hands, and we enable that.  End user onboarded applications are behind more than one third of all cybersecurity hacks.  We provide the solution to manage that through enabling users to select their own technology and we automatically protect those applications.

About the role

At Cerby, software engineers are at the heart of driving our technology and product innovation. As a Principal Software Engineer - On-Premise Agent, you will spearhead the design, development, and deployment of Cerby’s lightweight, enterprise-grade endpoint agent. This agent is a cornerstone of our strategy to securely connect to and automate intranet applications within customer on-premise environments, significantly expanding Cerby's capabilities and market reach. You will take ownership of this critical initiative, collaborate cross-functionally (including with InfoSec, Network, and IT Ops stakeholders from our customers), and drive the success of our on-premise automation capabilities. You will help lead a security-first engineering culture while ensuring the agent is robust, efficient, resource-conscious, and delivers significant value by extending Cerby's protection and automation into complex enterprise networks.

What you'll do

• Design and Develop: Architect and build a scalable, high-performance, lightweight exceptionally secure on-premise agent and data core focused on security and automation of intranet applications, aligning with business goals and delivering customer value.
• Agent Architecture: Design and implement a secure, resilient, and performant on-premise agent architecture, considering cross-platform compatibility (e.g., Windows, macOS, Linux) and minimal resource footprint.
• Cryptographic Implementation & Validation (Rust/Go): Lead the effort to implement, and rigorously validate existing cryptographic algorithm designs into highly secure, performant Rust/Go native implementations for the agent's core. This includes secure local data storage, key management, and derivation.
