Senior Software Engineer – Security & Distributed Systems

RapidFort is a cybersecurity company focused on securing and optimizing modern software supply chains and cloud-native environments. The Senior Software Engineer will design and develop reliable backend services and distributed systems for the company’s security platform, processing large-scale security and software supply chain data across Linux, containerized, Kubernetes, and cloud environments.

Responsibilities:

• Design, build, and maintain highly reliable backend services and distributed systems
• Develop core components of RapidFort’s cybersecurity and software supply chain security platform
• Build systems for processing, analyzing, and managing large volumes of security, vulnerability, package, container, and runtime data
• 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

Requirements:

• • 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
• • Deep understanding of distributed systems and production backend architecture
• • Strong knowledge of Linux systems and internals
• • Experience building APIs, backend services, microservices, or large-scale data-processing systems
• • Hands-on experience with Docker, containers, and Kubernetes
• • 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
• U.S. citizenship is required for this position due to RapidFort's work with U.S. government and Department of Defense customers and the potential for this role to support security-sensitive public-sector environments
• • 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
