• Reverse engineer and automate control of network-connected devices, taking on the most complex devices and protocols
• Drive identification and fingerprint network-connected devices across embedded, IoT, and OT/ICS endpoints
• Architect and evolve our device interaction application, owning challenging components end-to-end
• Set technical direction on complex device issues and bugs, including hard-to-reproduce and protocol-level problems
• Leverage AI tools and coding assistants as a core part of your day-to-day engineering workflow-including reverse engineering research, code generation, debugging, test creation, and documentation
• Write efficient, well-documented production code that other engineers can build on with confidence
• Design and maintain automated test cases and frameworks that ensure the integrity of our device coverage
• Build and improve internal tooling and automation that accelerates the Device Engineering team
• Mentor engineers, lead code reviews, and grow the technical depth of the team through pairing, design reviews, and knowledge sharing
• Collaborate cross-functionally with product, reverse engineering, threat research, and customer-facing teams to translate field needs into engineering outcomes

Qualifications :

• 6+ years of experience as a software engineer, with a track record of shipping production systems and owning complex technical work
• Deep expertise developing and debugging in Node.js, with strong fundamentals in modern JavaScript/TypeScript
• Strong reverse engineering skills, including network protocol analysis, traffic capture interpretation, and device behavior reconstruction
• Proficiency with relational databases, including schema design and query optimization for large datasets
• Strong command of Unix/Linux environments, including systems-level debugging and performance analysis
• Working proficiency with Docker and containerized development and deployment workflows
• Solid understanding of network transport and application layer protocols (TCP/IP, TLS, and common embedded/industrial protocols)
• Strong command of regular expressions and pattern-based parsing for protocol and device fingerprinting
• Demonstrated ability to mentor engineers, lead technical design discussions, and influence direction across teams
• Excellent communication and collaboration skills, with the ability to work effectively in a fast-paced, evolving, remote-first environment
• Bonus: experience with ICS/OT environments, embedded systems, or xIoT device security
