  • Demonstrated experience with systems design for distributed or high-availability services, including clear understanding of scalability, reliability, and observability.
  • Hands-on experience building or maintaining scanning, detection, or similar engine-like systems (e.g., vulnerability scanning, security scanning, data processing pipelines, or similar high-throughput engines).
  • Strong software engineering fundamentals: data structures, algorithms, concurrency, and performance optimization.

Responsibilities
  • Own end-to-end systems design for key components of the scanning engine, from initial design through implementation, deployment, and ongoing iteration
  • Design and implement high-quality services in Python and Go that power our scanning workflows, ensuring code is maintainable, well-tested, and observable.
  • Improve performance, scalability, and reliability of the scanning engine, optimizing for large-scale, distributed scanning workloads and strict SLAs.
  • Partner with security, product, and data teams to translate detection and scanning requirements into robust, production-ready systems and APIs.
  • Drive technical excellence and standards in the scanning engine codebase, including code review rigor, design documentation, and best practices for secure coding.
  • Contribute to architecture and roadmap decisions for the scanning platform, evaluating tradeoffs and proposing solutions that balance speed, quality, and risk.
  • Diagnose and resolve complex production issues related to scanning performance, accuracy, and stability, collaborating with SRE/Infra teams where needed.
  • Mentor and support other engineers on the team through design feedback, pairing, and knowledge sharing around systems design and scanning domain concepts.
Desired Qualifications
  • Cyber security domain knowledge in scanning through endpoints.
