About RevelAt Revel, we are revolutionizing the way the world's most critical hardware is controlled-across aerospace, automotive, energy, and manufacturing sectors. Our next-generation software stack combines an intuitive command/control interface, a specialized programming language tailored for hardware control, and a high-performance runtime environment. We empower engineers to build, test, and deploy critical systems rapidly, reliably, and safely. Role Overview We are looking for an Embedded Software Engineer to join our rapidly growing engineering team. In this role, you will build the critical software layer that bridges Revel's high-performance runtime and the complex physical world of industrial machinery. We are seeking a systems expert who obsesses over performance and abstraction, to whom a millisecond seems like an eternity, and who takes pride in implementing drivers that are robust, portable, and mathematically correct.Responsibilities Integrate industrial hardware, from standard PLCs to specialized instrumentation, navigating complex register maps and standard protocols. Reverse-engineer "black box" hardware behavior when vendor documentation falls short, treating datasheets as hypotheses rather than facts. Implement Hardware Abstraction Layers (HALs) that encapsulate complexity behind intuitive, type-safe APIs. Write portable, high-performance Rust code targeting Linux userspace today but designed to be architecture-agnostic. Own the physical boundary using logic analyzers and oscilloscopes to drive troubleshooting to the absolute root cause. Treat system reliability as a safety requirement, rigorously validating code to prevent failures that could result in physical damage or dangerous behavior. Qualifications Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or related field (or equivalent practical experience). 3+ years of professional experience in systems programming (C/C++/Rust) or embedded software development. High proficiency in Rust, C, or C++, with a willingness to work primarily in Rust. Strong understanding of Linux internals, including sockets, syscalls, and kernel-to-userspace data flow. Ability to interpret electrical schematics, datasheets, and timing diagrams to translate hardware behavior into code. Experience implementing and debugging industrial protocols (e.g., Modbus, TCP/IP, SPI, I2C, CAN, UART, RS-485). Proficiency with hardware debugging tools like logic analyzers, oscilloscopes, and packet sniffers. Preferred Qualifications Prior experience shipping production code in Rust. Experience writing Rust in no_std environments. Deep familiarity with Modbus, EtherNet/IP, EtherCAT, PROFINET, or IO-Link. Relentless root-cause mindset that refuses to accept flaky behavior. Intuitive grasp of latency costs, timing requirements, and determinism.
