• Design scalable APIs, services, data pipelines, and internal platform components
• Develop software that operates across Linux, containerized, Kubernetes, and cloud environments
• Solve complex problems involving concurrency, performance, scalability, reliability, and distributed processing
• Work with container images, software packages, dependencies, vulnerabilities, SBOMs, and other software supply chain data
• Improve the performance and efficiency of systems handling large-scale security analysis and remediation workflows
• Diagnose complex problems across applications, operating systems, containers, networks, and distributed services
• Design systems with security, reliability, observability, and fault tolerance built in from the beginning
• Write clean, maintainable, well-tested production code
• Participate in architecture and technical design discussions
• Review code and help establish strong engineering practices across the team
• Work closely with security researchers, product managers, and other engineers to turn complex security problems into scalable product capabilities
• Take ownership of projects from technical design through production deployment

Skills

• * 5+ years of professional software engineering experience, ideally building backend platforms or distributed systems
• * Strong programming experience with Python, Go, C++, Java, or similar backend/system-level languages

• * Experience designing software for cloud environments such as AWS, Azure, or GCP
• * Strong understanding of networking, processes, filesystems, memory, CPU utilization, and system performance
• * Experience with relational and/or NoSQL databases and large-scale data systems
• * Understanding of concurrency, asynchronous processing, queues, caching, and distributed workloads
• * Strong debugging and problem-solving skills across multiple layers of a technology stack
• * Ability to independently own complex engineering problems from design through implementation
• * Strong written and verbal communication skills
• You do not need to be a traditional security engineer, but you should be interested in building software that solves difficult cybersecurity problems
• * Software supply chain security
• * Application or cloud security
• * Vulnerability management
• * Container security
• * Kubernetes security
• * Software composition analysis
• * SBOMs and software dependency analysis
• * CVEs and vulnerability intelligence
• * Linux security
• * DevSecOps
• * Package management and software build systems
• * Runtime security or workload analysis

• * Experience building security products or developer/security infrastructure
• * Experience working with very large software or vulnerability datasets
• * Deep understanding of container images, registries, layers, packages, and dependencies
• * Experience with Kubernetes internals and container runtimes
• * Knowledge of Linux package ecosystems such as RPM, DEB, APK, or similar
• * Experience with CI/CD systems and modern software build pipelines
• * Experience profiling and optimizing CPU, memory, disk, and network performance
• * Familiarity with open-source security tooling and vulnerability databases
• * Experience building highly available systems operating across multiple environments or clusters
• * Experience in a high-growth cybersecurity, cloud infrastructure, or enterprise software company
