Requirements

Strong experience as a Senior Software Engineer (or equivalent) working on backend or systems-level services.
Proficiency in at least one of Python or Go, with the ability and willingness to work in both languages over time.
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).
TODO: Clarify how strict security/scanning background is vs. openness to adjacent domains (data pipelines, compilers, search, etc.).
Strong software engineering fundamentals: data structures, algorithms, concurrency, and performance optimization.
Experience working in a cloud-native environment (e.g., microservices, containers, CI/CD, monitoring, logging).
TODO: Confirm primary cloud provider(s) and any required tools (Kubernetes, Docker, etc.).
Ability to collaborate effectively across teams, including product, security, and platform/infra, and communicate tradeoffs clearly to technical and non-technical stakeholders.
Proven track record of owning projects end-to-end, from problem definition and design through implementation, rollout, and iteration.
Comfort operating in a fast-paced, evolving environment, making pragmatic technical decisions while maintaining quality and security.
Experience with code quality practices (testing, static analysis, code reviews) and building maintainable systems.

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.
