About The Position

We're seeking a highly skilled Staff Device Engineer to join our Device Engineering team as a strong individual contributor. In this role, you will tackle the toughest reverse engineering, fingerprinting, and automated control challenges across the network-connected devices that power critical industrial environments. No two devices are alike - each one is its own challenge. You will own complex technical work end-to-end, contribute deep subject-matter expertise to the team, and partner with product, threat research, and reverse engineering peers to deliver capabilities that defend our customers' operations.

Requirements

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, HTTP, 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
