Embedded Software Engineer - Embedded Systems & Firmware
Company Background:
Specter is creating a software-defined "control plane" for the physical world. We are starting with protecting American businesses by granting them ubiquitous perception over their physical assets.
To do so, we are creating a connected hardware-software ecosystem on top of multi-modal wireless mesh sensing technology. This allows us to drive down the cost and time of deploying sensors by 10x. Our platform will ultimately become the perception engine for a company's physical footprint, enabling real-time perimeter visibility, autonomous operations management, and "digital twinning" of physical processes.
Our co-founders Xerxes and Philip are passionate about empowering our partners in the fast approaching world of physical AI and robotics. We are a small, fast growing team who hail from Anduril, Tesla, Uber, and the U.S. Special Forces.
Role + Responsibilities:
Specter is hiring an Embedded Software Engineer to own the full on-device software stack for our distributed wireless mesh sensor nodes, including integration with RF modules, cameras, and multi-modal sensors.
Responsibilities include:

Designing, implementing, and maintaining performant, reliable firmware and software for Specter's current and future edge devices across a wide range of embedded platforms (embedded Linux on SoCs, RTOS, bare-metal on microcontrollers).
Owning the integration of RF modules, cameras, and multi-modal sensors (e.g., environmental, motion, acoustic) into the embedded software stack, including driver development, data pipelines, and hardware enablement.
Performing board bring-up, reading datasheets/schematics, and debugging complex hardware/software interactions using oscilloscopes, logic analyzers, JTAG/SWD, and other diagnostic tools.
Collaborating closely with Hardware Engineering (EE, RF, ME), Product Engineering, and backend software teams to co-design interfaces, support new hardware platforms, and enable rapid prototyping and iteration from concept to production deployment.
Building and maintaining reusable build, test, and deployment infrastructure for embedded targets-including CI/CD pipelines, automated testing, and over-the-air (OTA) update mechanisms-to accelerate development of new products and features.
Debugging and optimizing system performance in real-world deployments, focusing on power consumption, memory footprint, reliability, and edge-case fault tolerance.
Contributing to foundational platform components such as bootloaders, secure boot implementation, and modular driver frameworks to support fast development of next-generation devices.

Qualifications:

Proficiency in writing software for embedded targets using C, C++, Rust, or similar languages.
Experience with embedded Linux on System-on-Chips (SoCs), real-time operating systems (RTOS), or bare-metal programming for microcontrollers.
Hands-on experience with kernel driver development (Linux) and/or low-level peripheral drivers on microcontrollers, integrating both on-chip and external hardware peripherals.
Familiarity with a variety of communication protocols and interfaces, including low-level serial buses (e.g., SPI, I2C, UART, CAN, RS485), networking standards (e.g., Ethernet-including 10BASE-T1S, , and high-speed peripheral interfaces (e.g., MIPI CSI-2, SDIO, PCIe).
Comfortable debugging hardware using basic lab equipment including logic analyzers, oscilloscopes, spectrum analyzers, etc

Bonus Qualifications (strong experience in one or more of the following areas):

Embedded Security (e.g., OTA update infrastructure, secure boot mechanisms, hardware security modules like TPM or secure elements).
Power Electronics (e.g., software control of motors, DC-DC converters, or battery management systems in embedded environments).
Connectivity (e.g., Bluetooth, Cellular, Wi-Fi, CAN, Ethernet; including integrations like OpenWRT for wireless routing, 10Base-T1S for single-pair Ethernet, or cellular modem drivers).
Camera Integration (e.g., integrating image sensors or MIPI CSI-2 devices into embedded systems, including FPGA/DSP-based processing for video pipelines or computer vision applications).
Operating Systems & Build Infrastructure(e.g., Nix/NixOS-based systems, reproducible builds, declarative system configuration, cross-compilation, and deployment pipelines for embedded Linux).
