About the Role

The SandboxAQ Cybersecurity group is looking for a talented Staff Software Engineer to join our team and lead the development of our API and SDK integration platform for third-party enterprise customers. As a key member of our team, you will work across the stack (backend, frontend, infrastructure) to design and implement scalable integration solutions that connect our cybersecurity platform with leading security vendors like CrowdStrike, Qualys, and other enterprise security tools. This role offers the opportunity to work at the intersection of API design, enterprise integration, and distributed systems to shape how our customers consume and integrate our security capabilities into their existing workflows.

You will get to work with a diverse group of engineers, product managers, solution architects, cryptographers, and ML experts to rapidly bring integration solutions to market while ensuring seamless interoperability with the broader cybersecurity ecosystem.

How We Succeed Together

We move fast, build with purpose, and are obsessed with making an impact. Our culture is built for those who want to be at the forefront of innovation, and it's guided by these core principles:

• We are passionate about solving real-world problems for our customers.
• We take deep ownership of our work and hold ourselves to the highest standards of excellence.

What You'll Do

You will build core API and SDK features that enable seamless integration between our cybersecurity platform and third-party security tools like CrowdStrike, Qualys, Splunk, and other enterprise security platforms. As part of this role, you'll design and implement developer-friendly SDKs and APIs that abstract complex security operations into intuitive interfaces for enterprise customers, while developing scalable, performant and highly available integration solutions oriented at different enterprise environments, supporting both cloud and on-premises deployments.

You'll create comprehensive integration frameworks that handle authentication, data transformation, error handling, and monitoring across diverse third-party platforms, building robust webhook and event streaming capabilities to enable real-time data synchronization between our platform and customer security tools. The position involves designing and implementing API versioning strategies, backward compatibility mechanisms, and migration paths for enterprise customers, while collaborating directly with enterprise customers and third-party vendors to understand integration requirements and ensure successful deployments.

Your responsibilities will include automating, deploying, diligently testing and maintaining integration software as part of a long-lasting software engineering cycle, establishing monitoring, observability, and alerting systems for integration health and performance across customer environments, and contributing to API documentation, integration guides, and developer resources that enable customer success.
