Job#: 3044339 Job Description: Software Design Engineer
Type: 7-month contract to start
Location: REDMOND, Washington
Schedule: Hybrid, 3 days onsite and 2 days remote
Compensation: $70-83/hr w2
Role Overview
As a member of the engineering team, you will build and advance a next-generation firmware security analysis platform. This system combines large language models (LLMs), compiler technology, and automated fuzzing to identify security vulnerabilities in firmware at scale. You will work directly with security researchers, compiler engineers, and platform developers to build production-quality tooling spanning LLVM, fuzzing infrastructure, static analysis, and AI-assisted automation.
Key Responsibilities
- Develop preprocessing pipelines that compile C/C++ firmware code into LLVM Intermediate Representation (IR).
- Implement and maintain LLVM-based transformations to make firmware suitable for off-target analysis and fuzzing.
- Create and improve code-analysis workflows, including call-graph extraction, metadata generation, and static-analysis integrations.
- Design and maintain systems that generate and execute fuzzing campaigns using modern fuzzing frameworks.
- Build scalable automation that combines compiler infrastructure, security tooling, and AI-driven workflows.
- Improve system reliability, modularity, test coverage, and CI/CD automation.
- Create developer documentation, onboarding guides, and architectural references.
- Participate in design reviews and technical architecture discussions.
Required Qualifications
Education: Bachelor's degree in Computer Science, Computer Engineering, or a related technical field, or equivalent practical experience.
Experience: Strong professional experience developing software in C/C++.
Technical Skills:- 8-10 years of hands-on experience with compiler technologies, LLVM, or low-level systems programming.
- Experience working with fuzzing frameworks such as libFuzzer, AFL, AFL++, or similar technologies.
- Strong understanding of software security principles, including memory-safety vulnerabilities and root-cause analysis.
- Proficiency with Python for automation and tooling development.
- Experience using Git-based development workflows.
Preferred Qualifications
- Experience with firmware, embedded systems, device software, or bare-metal development.
- Knowledge of hardware abstraction layers (HALs), MMIO, emulation, rehosting, or cross-compilation techniques.
- Experience with static-analysis platforms such as CodeQL.
- Familiarity with program-analysis concepts such as call graphs, data-flow analysis, or IR transformations.
- Experience integrating AI, machine learning, or LLM technologies into engineering workflows.
- Previous open-source contributor or maintainer experience.
- Experience building CI/CD pipelines and release automation.
- Familiarity with Azure DevOps, GitHub, or similar development platforms.
