The SandboxAQ Cybersecurity group is looking for a Staff Software Engineer to build the core data collection and integration fabric of our platform. This isn't just an SDK role; you will be responsible for designing, building, and maintaining the critical first-party sensors that our customers deploy in their most sensitive environments.
You'll be working at a low level, writing high-performance Rust code for passive network analyzers, filesystem scanners, and dynamic & static application tracers. You will also contribute to our third-party integration framework, pulling data at scale from the entire enterprise security ecosystem.
This is a high-impact role with a direct line to solving our most critical customer challenges. We need a pragmatic and systems-oriented engineer who can own problems end-to-end, from design and estimation to implementation and mentorship.
What You'll Do- Design, implement, and maintain our suite of 1P sensors in Rust, focusing on performance, stability, and security.
- Contribute to the design and implementation of our 3P integration framework, solving challenges related to rate limiting, data ingestion at scale, and state management.
- Contribute to our SDK to enable seamless integration for partners and customers.
- Own new features end-to-end, collaborating with Product Managers and TPMs to refine requirements, estimate work, and deliver robust solutions.
- Help mentor one of our junior engineers, providing technical guidance and leveling up the team's Rust expertise.
- Contribute to our team's culture of ownership, accountability, and diligence.
- 5+ years of professional software engineering experience, with a track record of shipping complex, scalable systems.
- Demonstrated expertise in Rust for systems-level programming.
- Deep understanding of low-level OS/system and networking concepts (e.g., filesystems, network protocols, system calls).
- Proven ability to design and implement systems that handle data processing at scale.
- You are skilled at translating complex customer needs into technical requirements and are comfortable working with external stakeholders to solve their challenges.
- You know how to balance delivering high-quality, production-ready code quickly with long-term maintainability.
- You thrive in a distributed, multicultural team and can articulate complex ideas clearly to technical and non-technical audiences.
- Optional experience with Java/Kotlin, Golang or Python.
- Experience in the cybersecurity domain, particularly with Endpoint Detection and Response (EDR) or antivirus (AV) products.
- Experience with enterprise security APIs (e.g., CrowdStrike, Splunk, Qualys).
- Familiarity with Kafka, KStreams, or other streaming data technologies.
The US base salary range for this full-time position is expected to be $183k-$256k per year. Our salary ranges are determined by role and level. Within the range, individual pay is determined by factors including job-related skills, experience, and relevant education or training.
