* The Opportunity:

**### We are seeking a Senior Vulnerability Researcher with deep expertise in cloud-native architecture, container runtimes, and advanced binary analysis. This role is ideal for a low-level expert who thrives on technical ambiguity and enjoys hunting for vulnerabilities within the "DNA of the cloud." You will use automated reasoning and manual deep-dives to uncover escapes and logic flaws in Kubernetes infrastructure, playing a key role in evaluating the security of critical distributed systems and contributing directly to national cybersecurity efforts.###

### ###
** Responsibilities:*** ### Conduct deep-dive research into OCI runtimes (runc, crun) and Linux kernel primitives (name spaces, cgroups, eBPF) to identify breakout and privilege escalation paths.* ### Perform static and dynamic analysis on compiled binaries (Go, Rust, C++) using IDA Pro, Ghidra, or Binary Ninja to map undocumented logic and potential security issues.* ### Build and maintain custom fuzzing harnesses (e.g., AFL++, lib Fuzzer) to stress-test gRPC interfaces, service mesh components, and microservices.
* ### Utilize concolic execution tools (e.g., Angr, Manticore) to automate the discovery of complex execution paths and bypass security checks.* ### Investigate edge-case behaviors in containerized environments and low-level system initialization logic to reveal hidden attack surfaces.* ### Develop custom tools and scripts (primarily in Python3) to automate research workflows, protocol decoding, and memory analysis.* ### Document findings clearly and translate technical complexity into actionable reports for security and engineering teams.###

###
*
* Qualifications:

**###
* Required***:*** ### An active Top Secret clearance.* ### 7+ years of professional experience in vulnerability research, software exploitation, or low-level engineering.* ### Expert-level proficiency in Go, Rust, and C/C++.* ### Strong command of Python3 for scripting and automation of research tasks.* ### Deep understanding of x86/ARM assembly and memory corruption primitives.* ### Proven track record of finding vulnerabilities in distributed systems, virtualization layers, or container runtimes.
* ### Hands-on experience with disassembly and decompilation tools (e.g., IDA Pro, Ghidra, Binary Ninja) and debugging tools (GDB).* ### Detailed understanding of Linux kernel internals, specifically name spaces, cgroups, and the container execution model.* ###

Experience with automated bug-hunting techniques, including fuzzing and symbolic/concolic execution.### ### ### ###
** Desired:*** ### An active SCI clearance is highly desired.* ###

Experience with Kubernetes security architecture and service mesh implementations (Istio, Linkerd).* ### Familiarity with hardware-assisted isolation technologies and TEEs (Trusted Execution Environments).* ### Ability to build scalable security tooling and infrastructure to support analysis workflows in a team setting.* ### Background in cloud provider security (AWS, Azure, or GCP) and underlying hypervisor technology.###
