Embedded Software Tools Engineer at Lyte AI – Sunnyvale | Jobyssey

About the role

We are looking for a Senior Embedded Software Tools Engineer to design, build, and maintain the software tools that enable efficient development, testing, manufacturing, and deployment of embedded systems at scale. This role focuses on creating robust internal tools, workflows, and infrastructure that support firmware, driver, and system engineers across development, validation, factory, and production environments.
You will work closely with embedded, firmware, silicon, systems, test, and manufacturing teams to understand workflows and pain points, then design tools that improve developer productivity, software quality, test coverage, and system reliability, from early bring-up through factory and field deployment.

What you'll do

Design, develop, and maintain embedded software development and test tools used across the organization
Build tooling to support:
- Chip, SoC, and board bring-up
- Firmware and driver development
- Characterization of RTOS- and Linux-based embedded systems
Develop tools for flashing, provisioning, configuration, calibration, and recovery of embedded devices
Create debugging, tracing, and diagnostics tools that interface with:
- JTAG/SWD and other hardware debug interfaces
- Target-side firmware, bootloaders, kernels, and drivers
Build automation for:
- Build, test, and deployment pipelines
- Hardware-in-the-loop (HIL) and system-level testing
- Factory and manufacturing test systems
Design and maintain tooling for factory use cases, including:
- Board and system-level test automation
- Production flashing and configuration
- Validation, calibration, and pass/fail reporting
Develop simulation, emulation, and test harnesses to enable faster iteration without physical hardware
Integrate toolchains across heterogeneous targets (MCUs, CPUs, DSPs, NPUs, GPUs, custom ASICs)
Improve observability of embedded systems through logging, metrics, tracing, and crash analysis
Ensure tools are reliable, scalable, secure, and easy for engineers and factory operators to use
Collaborate closely with firmware, driver, hardware, test, manufacturing, and systems teams to define requirements and interfaces
Support production, manufacturing, and field-debug workflows with robust tooling and root-cause analysis

Required Qualifications

Bachelor's degree or higher in Computer Engineering, Computer Science, Electrical Engineering, or a related field
7+ years of experience developing software tools for embedded or systems environments
Strong software engineering skills in:
- Python
- C and/or C++
- Shell scripting (Bash or similar)
Solid understanding of embedded systems fundamentals:
- Boot flows, memory, interrupts, and concurrency
- RTOS- and Linux-based embedded systems
Experience working with embedded build systems, cross-compilation toolchains, and flashing workflows
Familiarity with firmware and driver development and bring-up processes
Experience designing developer- and operator-facing tools with a focus on usability, reliability, and automation
Strong debugging and problem-solving skills across hardware and software boundaries
Ability to collaborate effectively across hardware, firmware, software, test, and manufacturing teams

Preferred Qualifications

Experience with embedded Linux environments:
- Yocto, Buildroot, cross-compilation toolchains
- Kernel build and configuration workflows
Experience with RTOS-based systems (e.g., FreeRTOS, Zephyr, QNX, ThreadX)
Familiarity with hardware debug and trace tools:
- JTAG/SWD, OpenOCD, GDB, Trace32, Lauterbach
Experience building HIL, SIL, and automated factory test frameworks
Experience with emulation and simulation tools (QEMU, virtual platforms)
Experience with CI/CD systems for embedded software
Experience supporting manufacturing, factory, and production test environments
Experience working across multiple processor architectures:
- ARM Cortex-M/R/A, DSPs, NPUs, GPUs, custom accelerators
Knowledge of CUDA and GPU programming for tooling, testing, simulation, or acceleration use cases
Background in robotics, autonomous systems, or other complex embedded products

Modern development workflows:
- Git-based version control, code reviews, CI pipelines
Build systems and tooling:
- CMake, Make, Bazel, or similar
Debugging, profiling, and tracing tools for embedded and Linux systems
Automation frameworks for development, test, and factory workflows
Strong documentation practices:
- Tool usage guides, onboarding docs, factory procedures, and troubleshooting manuals
Embedded software best practices:
- Reproducible builds
- Deterministic tooling and test results
- Robust error handling and diagnostics
- Long-term maintainability and scalability of tooling and infrastructure
