Job summary

Blueprint Technologies, a Bellevue-based technology solutions firm, seeks an Embedded Software Engineer to build an advanced platform for firmware security analysis. You’ll develop tooling in C++/Python, create LLVM-based analysis passes, and advance AI-assisted automation with security researchers.

You will work on scalable pipelines, fuzzing harnesses, and LLVM IR transformations, collaborating with engineers to deliver production-ready security tooling.

Qualifications

• Bachelor’s degree in CS/CE/EE or equivalent practical experience.
• 7+ years of professional experience developing systems software using C and/or C++.
• 5+ years of experience with LLVM, compiler infrastructure, compiler development, or program analysis.
• 3–5+ years of experience with fuzzing, vulnerability research, or application security.
• Experience developing compiler passes, static analysis tools, or code transformation frameworks.
• Strong understanding of LLVM IR and compiler optimization concepts.
• Experience debugging low-level software, memory corruption issues, and complex system behavior.
• Proficiency with Python for automation, tooling, or pipeline development.
• Experience working in Linux development environments.

Responsibilities

• Design, develop, and maintain automated firmware security analysis pipelines for vulnerability discovery.
• Build low-level tooling using C++, Python, and LLVM to analyze firmware at scale.
• Develop compiler passes and transformations to convert firmware into analyzable LLVM IR.
• Create, improve, and maintain fuzzing harnesses to maximize code coverage and uncover vulnerabilities.
• Investigate crashes identified during fuzzing campaigns and perform root-cause analysis.
• Improve vulnerability detection accuracy by reducing false positives and enhancing automated analysis workflows.
• Develop and enhance AI-assisted systems that classify firmware functionality and generate security artifacts.
• Debug firmware rehosting environments and resolve issues affecting automated analysis.
• Collaborate with compiler engineers, software engineers, and security researchers to review architectures and validate findings.
• Design scalable automation, testing, and CI/CD workflows that improve development efficiency and platform reliability.
• Improve code quality through testing, documentation, dependency management, and engineering best practices.
• Contribute to release readiness, developer onboarding experiences, and open-source preparation activities.
• Evaluate and integrate new compiler, security, and AI technologies that improve platform capabilities.
