Job Title: Senior Electrical Engineer Department: Product Development: Hardware Reports To: Director of Hardware & Firmware Engineering Location: Pullman, Washington Salary: $125,000 annually  Applicants must be legally authorized to work in the United States. Addium, Inc. does not sponsor employment visas now or in the future.  About Addium  Addium is a leading ag-tech company uniting science, sensors, and software to deliver end-to-end solutions in agriculture and food safety. Serving 34,000+ global clients with 60M+ daily sensor readings, we turn raw data into actionable insights that conserve resources, improve food safety, and drive measurable impact. Our mission is to make the invisible visible—transforming data into clarity, action, and automation. Trusted by partners like Mondelez, PepsiCo, Ferrero, and Green Thumb Industries, we stand for innovation, reliability, and a bold commitment to the future of agriculture. Position Summary As a Senior Electrical Engineer at Addium, you design, develop, and validate complex electrical systems from concept through production, ensuring products meet technical, quality, and market requirements. You collaborate with cross-functional teams including electrical, firmware, embedded, mechanical, and systems engineering to deliver innovative, reliable solutions. Working with a high degree of independence, you drive projects through the EVT/DVT/PVT development process, support new product introductions with manufacturing partners, and champion engineering best practices and continuous improvement. Key Responsibilities * Work 90–100% independently, taking ownership of complex projects and ensuring successful completion with minimal supervision. * Lead system design efforts across analog/mixed-signal circuits, low-noise sensor front-ends, and power electronics; manage significant projects and oversee circuit design and component selection to meet product requirements. * Own EMC design-for-compliance work — filtering, grounding, and layout strategy to address common-mode and differential-mode noise rather than treating compliance as a late-stage test-and-fix step; partner with test labs to prepare products for CE and FCC certification. * Collaborate directly with firmware/embedded engineers on hardware-software interfaces, and with mechanical engineering on packaging and integration constraints. * Support wireless subsystem design and integration where applicable, including our Wirepas mesh fleet and emerging LoRa-based sensor architectures. * Partner with contract manufacturers on DFM/DFT reviews and drive designs through EVT, DVT, and PVT gates. * Assess the technical competence of EE candidates and less experienced engineers, providing constructive feedback and guidance. * Actively participate in the development of other engineers, sharing expertise and fostering an environment of continuous learning. * Lead the design and development of new products, leveraging subject matter expertise in electrical engineering to create innovative solutions that successfully enter the market. Qualifications * Bachelor's degree in Electrical Engineering, Computer Engineering, or related field * 8-10+ years of industry experience * Very strong PCB design ability, including analog/mixed-signal and power electronics layout. * Demonstrated experience designing for EMC compliance (CE, FCC) — not just test preparation, but proactive noise mitigation through circuit and layout design. * Working knowledge of relevant test equipment (oscilloscope, spectrum analyzer, network analyzer) for debugging and pre-compliance verification. * Familiarity with wireless sensor networking concepts (mesh or LPWAN architectures) a plus. * Expert engineering documentation — design history, requirements traceability, and reference-quality records maintained in [Confluence / Jira (HDEV) / PLM system] — that serves as a reference for less seasoned EEs. * Experience analyzing product testing needs, creating test processes, and performing tests. * Comfort working within a formal stage-gate NPI process (EVT/DVT/PVT) and collaborating directly with contract manufacturers on DFM/DFT. * Cross-divisional understanding of the scientific knowledge relating to successful product development. * A resource for industry application knowledge with scientific understanding of Addium products. * Skilled in Altium Designer, Altium 365, Altium Develop, and AI tools surrounding Altium and PCB design. What We Offer * Competitive salary  * Comprehensive medical, dental, and vision insurance * 401(k) retirement plan with a company match (up to 4% after your first year) * Paid Time Off, Sick Leave, and 11 Paid Holidays  * Ongoing learning and development opportunities to support your growth * Clear paths for career advancement as you grow with us * Company-paid life and disability insurance for peace of mind * Health savings account and flexible spending account options * A collaborative, inclusive work environment with regular team-building activities and fun company events Addium, Inc. is an Equal Opportunity Employer. We are committed to creating an inclusive and diverse workplace where all individuals are respected, valued, and supported.
