Embedded and Interactive Systems Engineer

Nudena L.L.C.; Detroit (MI); Hybrid; USD 100,000 - 150,000; Part time

Job summary

Nudena L.L.C. seeks an Embedded and Interactive Systems Engineer for a paid, project-based independent contractor role.

You will bridge software and hardware, focusing on microcontrollers, networked devices, timing, calibration, logging, and recovery across evolving prototypes and production-ready systems. You will define architectures, review firmware and APIs, integrate sensors and actuators, and build bench tools for verification while documenting configurations, dependencies, and limitations

Qualifications

• Five or more years in embedded systems, interactive hardware, controls software, IoT, robotics, or comparable integration work.
• Strong experience with hardware communications, real-time behavior, debugging, and instrumentation.
• Evidence of shipping or deploying systems beyond a laptop-only environment.
• Maintainable code and practical documentation for the engineers and technicians who come next.
• Comfort working with incomplete prototypes and cross-discipline constraints.

Responsibilities

• Define the software and communications architecture connecting application events to device commands and feedback.
• Implement or review firmware, control services, APIs, protocols, state machines, timing, calibration, and logging.
• Integrate sensors, actuators, relays, controllers, local computing, or interactive applications as the project requires.
• Build bench test tools and simulated interfaces so subsystems can be verified before full assembly.
• Document dependencies, setup, configuration, versioning, diagnostics, and known limitations.
• Work with electrical and systems leads on safe states, latency targets, and integrated verification.

Job description

Embedded and Interactive Systems Engineer

Accepting applications

You build the layer where software meets hardware: microcontrollers, networked devices, message protocols, timing, calibration, logging, and recovery. You help a team move from an early demonstration toward a system that can be tested and explained.

What you'll do

• Define the software and communications architecture connecting application events to device commands and feedback
• Implement or review firmware, control services, APIs, protocols, state machines, timing, calibration, and logging
• Integrate sensors, actuators, relays, controllers, local computing, or interactive applications as the project requires
• Build bench test tools and simulated interfaces so subsystems can be verified before full assembly
• Document dependencies, setup, configuration, versioning, diagnostics, and known limitations
• Work with electrical and systems leads on safe states, latency targets, and integrated verification

What you bring

• Five or more years in embedded systems, interactive hardware, controls software, IoT, robotics, or comparable integration work
• Strong experience with hardware communications, real-time behavior, debugging, and instrumentation
• Evidence of shipping or deploying systems beyond a laptop-only environment
• Maintainable code and practical documentation for the engineers and technicians who come next
• Comfort working with incomplete prototypes and cross-discipline constraints

Preferred experience

Relevant but not required.

• Unreal Engine, Unity, OpenXR, show control, experiential technology, kiosks, robotics, or networked equipment
• Device or edge deployment and observability
• Hardware in the loop testing

Integration architecture Firmware or control application Interface definitions Bench test utilities Logging and diagnostics Deployment and calibration documentation
