Staff Software Engineer, SDK/API

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.

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.
• We are a team that stands by our commitments to each other and our customers, building trust through reliability.
• We are proactive and action-oriented, always seeking opportunities to make a difference and drive our mission forward.
• We believe in amplifying our collective impact through collaboration.
• We are dedicated to seeing our projects through to the finish line, ensuring that every detail is accounted for and that our work has a lasting impact.

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.

• You have 5+ years of experience working as a Backend/Full-stack Software Engineer or similar role with focus on API development and third-party integrations
• You have proficiency in Rust, Kotlin and/or Go with a solid understanding of data structures and concurrency/synchronization for building scalable integration platforms
• You have industry or research knowledge of API design patterns, integration architectures, and enterprise software interoperability
• You have experience managing user-facing software at scale, including availability, observability, and security fundamentals across enterprise environments
• You understand software security principles, including API security, authentication flows (OAuth, SAML), and best practices in developing high-quality, secure integration code
• You have the ability to work in a small team to swiftly iterate and deliver production-quality APIs and SDKs
• You have hands-on experience building and maintaining REST APIs, GraphQL endpoints, or similar integration interfaces
• You understand enterprise integration patterns, including data transformation, error handling, rate limiting, and retry mechanisms
• You can work directly with enterprise customers to gather requirements, troubleshoot integration issues, and ensure successful deployments

• Experience with quantum computing concepts, quantum-safe cryptography implementations, or cryptography
• Extensive experience with API and third-party integration, particularly with cybersecurity platforms like CrowdStrike, Qualys, Splunk, or similar enterprise security tools
• Familiar with Kafka and KStreams for real-time event processing and data streaming between integrated systems
• Familiarity with Bazel for building complex, multi-language SDK projects
• Experience with OpenAPI/Swagger specifications and API documentation tooling
• Knowledge of enterprise authentication and authorization systems (LDAP, Active Directory, SAML, OAuth2)
• Previous work with webhook systems, event-driven architectures, and real-time data synchronization
• Understanding of enterprise deployment patterns, including container orchestration and API gateway technologies
