Electrical Engineer

Senior Electrical EngineerThe Role: Senior Electrical EngineerYou're a Senior Electrical Engineer who will take ownership of the hardware design of our emergency communication devices - sustaining and hardening the current product line while leading the transition to a next-generation, connected/digital platform.This role sits at the center of that transition: you will keep today's field-deployed hardware reliable while architecting the electrical and firmware foundation for tomorrow's digital products.Who We Are:Established in 1989 Kings III is a growing, dynamic company. We're a six-time winner of DFW Top Workplaces and nationally as a USA Today Top Workplace in 2020-2025. We're on a mission for change – for our communities, our customers, and our company. If you see yourself as a builder and change agent, this is the right place for you.More than 12% of our employees have been with the company for 10+ years, and an impressive 25% have been with us 5+ years. How do we do it? Here's what our employees say. We seek out creative employees who love opportunities for continuous learning and growth. We value innovation in not just our products, but the way we work, sell, and grow every day. We celebrate change and are always looking for ways to do things better!What You'll Do:Hardware & Firmware DesignOwn electrical and firmware design across the product line — from maintaining fielded emergency phones (analog/POTS and existing cellular variants) to architecting next-generation digital/connected devicesDrive schematic capture, PCB layout, and hardware bring-up for both legacy revisions and new digital hardware.Design cellular hardware to meet UL/FCC, PTCRB, and FirstNet certification requirements from the outset of next-generation device architecture.Design power architecture for next generation digital/connected devices, including battery backup, power management ICs, and low-power/sleep modes for cellular modulesLead firmware architecture for next-generation connected devices — cellular modules, embedded Linux/RTOS platforms, secure boot, OTA update mechanismsDesign and implement communication stacks (cellular, Wi-Fi, or LTE-M/NB-IoT) integrating with cloud-based monitoring and telemetryPartner with cloud/software teams to define device-to-cloud data protocols and APIsBuild in remote diagnostics, fleet health monitoring, and security (encryption, authentication, secure firmware signing) from the ground upOwn and maintain clean, accurate design documentation — BOMs, schematics, PCB layouts, and related engineering records — across both fielded and next-generation hardwareField & Manufacturing SupportRoot-cause field failures reported by Service and the EDC; drive corrective action from schematic/PCB level through firmwareManage component obsolescence, second-sourcing, and DFM/DFT issues across the product lineSupport manufacturing and test engineering for production runs, current and newCross-Functional & ComplianceWork directly with Product Management (reporting line to VP Product Development) to translate roadmap into engineering requirementsCollaborate with cross-functional teams to capture feature requirements for digital architecture and resolve recurring issues with existing productsSupport UL/FCC, PTCRB, and FirstNet certification testing for new cellular hardware revisionsMentor junior engineers and contractor/offshore development resourcesWhat You'll Bring:BS in Electrical Engineering or Computer Engineering (or equivalent experience); 8+ years in electrical/embedded hardware designStrong schematic capture and PCB design/review (Altium or equivalent); comfortable owning a board from concept through productionSolid firmware development skills in C/C++ for microcontrollers (ARM Cortex-M or similar); RTOS experience (FreeRTOS, Zephyr, or similar)Experience with cellular modules (Quectel, Telit, u-blox, or similar) and IoT connectivity protocols (MQTT, TLS/DTLS)Debugging with JTAG/SWD, oscilloscopes, logic analyzers; strong lab bring-up skillsExperience carrying a legacy hardware product through a connected/digital transitionFamiliarity with UL/FCC, PTCRB, and FirstNet certification processes for cellular hardwareExperience with power architecture for battery-backed, field-deployed electronics (power management ICs, battery charging/backup, low-power design)Nice to Have:Experience in life-safety, security, or emergency communications hardwareEmbedded Linux experienceExposure to cloud IoT platforms (AWS IoT Core or similar)What We Do:Our mission is simple - We provide critical communications services to help people in distress.Our Core Values are even simpler:Honesty & IntegrityService to the customer above all elseDo what is rightGood enough is not good enough: pursue excellenceEncourage individual initiative and growthBy living and breathing our mission and Core Values every day in everything we do, Kings III is creating opportunities for individuals and reducing risk, liabilities, and costs for businesses every day.Our primary client base includes commercial and multi-family real estate owners and property managers, and the most common areas we install our emergency phones are in elevators and at pool sides. We design, build, sell, install, service, and monitor those phones. Our Emergency Dispatch Center (EDC) provides 24/7/365 service to help dispatch local emergency services to people in distress. It's that simple, our employees help save lives every day.What's in it For You:Medical insurance with 1 HSA and 2 PPO plan optionsFlex Spending Account (FSA)/Dependent Care FSADental, vision, life, short- and long-term disability insuranceCritical illness and hospital indemnity plans401k with company contributionEmployee Assistance Program (EAP)Company paid telemedicine 24/7 accessWellness ProgramEmployee discount program8 paid holidays, plus 1 floating holiday15 days of PTO accrued in year 1Generous referral bonus programWork life balance (a must!)Team building, attendance at our annual kickoff each January, and other fun eventsRelaxed professional dress codeKings III is an Equal Opportunity Employer and committed to maintaining a drug-free workplace.
