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
