About The Position

Obsidian Labs, the advanced research, prototyping, and rapid experimentation arm of Obsidian Solutions Group, is seeking a highly capable Electrical Engineer to support the design, development, integration, and testing of next-generation hardware systems. This role supports multi-domain R&D initiatives including human–machine interfaces (HMI), wearable and distributed sensing systems, radiation and CBRN detection, autonomous platforms, and advanced manufacturing prototypes. The Electrical Engineer will work in a fast-paced, interdisciplinary environment alongside mechanical engineers, software developers, systems engineers, and subject-matter experts to transition concepts from whiteboard to field-ready prototypes. This role directly supports internal R&D, SBIR/OTA programs, customer-funded prototypes, and demonstration systems across defense, homeland security, and emerging technology markets.

Requirements

Bachelor's degree in Electrical Engineering or a closely related discipline.
3+ years of hands-on experience in electrical design, embedded systems, or hardware development.
Proficiency with schematic capture and PCB design tools (e.g., Altium, KiCad, Eagle, or equivalent).
Experience working with microcontrollers, sensors, and embedded peripherals.
Ability to work effectively in a rapid-iteration, prototype-driven environment.

Nice To Haves

Experience with wearable electronics, HMI devices, or distributed sensor systems.
Familiarity with radiation detection, CBRN sensors, or environmental monitoring systems.
Experience supporting SBIR/OTA or government R&D programs.
Knowledge of RF systems, GPS/PNT, or wireless communications (BLE, Wi-Fi, LTE, mesh).
Exposure to MIL-STD-810, EMI/EMC standards, or ruggedized system design.
Experience working in interdisciplinary R&D or startup-style lab environments.

Responsibilities

Design, develop, and document electrical architectures for prototype and low-rate production systems.
Create schematics, wiring diagrams, and PCB layouts for analog, digital, and mixed-signal systems.
Select components (MCUs, sensors, power systems, RF modules, interfaces) optimized for SWaP-constrained applications.
Support rapid iteration cycles from concept through prototype fabrication and test.
Collaborate with software and firmware teams to enable reliable data acquisition and system control.
Design and analyze power architectures including battery systems, power management ICs, and charging circuits.
Support EMI/EMC mitigation strategies and grounding/shielding best practices.
Assist with environmental robustness considerations aligned with operational use cases.
Collaborate with mechanical engineering on electro-mechanical integration and packaging.
Support design-for-manufacturability and design-for-test considerations.
Participate in hands-on lab build, integration, and troubleshooting activities.
Develop and execute bench-level and system-level test plans.
Support laboratory validation, field testing, and demonstration events.
Support transition of prototypes toward production or customer handoff.
