Join our fast‑paced and passionate team as a Principal Electrical Engineer (Level 5). In this role, you will shape the technical direction of our electrical and RF systems as we scale. You'll make major architectural decisions, guide engineering practices, and drive execution across multidisciplinary teams. This position is ideal for a highly experienced engineer who thrives in ambiguity, leads with initiative, and elevates the technical bar for the entire organization.
You will collaborate closely with leadership, influence product strategy, and mentor engineers across the team. Your work will directly impact our roadmap, reliability, and long‑term scalability.
Key Responsibilities
Provide technical leadership across electrical and RF design efforts, setting design standards, methodologies, and review practices
Lead complex engineering programs from concept through production, including requirements definition, architecture development, risk assessment, and cross‑functional alignment
Drive system‑level decision‑making, ensuring designs meet performance, manufacturability, reliability, and compliance requirements
Conduct and lead peer reviews, ensuring rigor in analysis, documentation, and verification
Mentor and support the development of junior and mid‑level engineers, fostering a culture of technical excellence, curiosity, and continuous improvement
Champion best practices in schedule management, data integrity, communication clarity, and engineering discipline
Identify opportunities for organizational and technical improvement, influencing long‑term engineering strategy
Requirements
Requirements
This position requires access to export-controlled information. Employment is contingent upon the applicant being a U.S. person as defined by 8 U.S.C. § 1324b(a)(3)
Experience:
Bachelor's degree in Electrical Engineering, ECE, or a related field; advanced degree preferred
10+ years of relevant industry experience, ideally including startup or high‑growth environments
Demonstrated expertise designing RF circuits in the 200 MHz to 20 GHz range
Deep experience with low‑noise analog design, high‑performance signal chains, and RF system integration
Proven track record designing RF PCBs with low loss, low crosstalk, and high signal integrity
Experience with Altium Designer is a plus
Skills:
Expert‑level understanding of analog, mixed‑signal, and RF circuit design principles
Ability to architect complex electrical systems, select components, and define design requirements
Proficiency with simulation tools such as SPICE for modeling and performance analysis
Strong familiarity with vendor ecosystems and component selection strategies
Deep knowledge of RF design concepts, PCB layout constraints, and best practices for high‑frequency systems
Ability to communicate complex technical concepts clearly to both technical and non‑technical stakeholders
Duties and Responsibilities:
Own electrical system architecture and guide implementation across engineering teams
Lead the design, development, analysis, documentation, and testing of products, systems, and subsystems
Produce and review formal design documentation, including architecture definitions and design synthesis
Perform advanced modeling and simulation of electrical and RF circuits
Oversee schematic capture, BOM strategy, and lifecycle management
Direct PCB layout efforts and ensure high‑quality manufacturing outputs
Manage the relationship with PCB vendors and fabrication partners to ensure the build quality and manufacturability
Lead root‑cause investigations and drive corrective actions for complex failures
Develop comprehensive test plans and oversee execution and reporting
Provide technical leadership and mentorship to engineers and technicians
Startup Mindset:
You thrive in ambiguity and enjoy building processes, systems, and infrastructure from scratch
You're adaptable, resourceful, and energized by solving problems across multiple domains
You embrace ownership and take initiative to move the organization forward
Benefits
The expected annual salary range for this position is $190,000-$235,000.
As a full-time employee, you will be eligible for Monarch's comprehensive benefits package, which includes:
Medical, Dental, and Vision insurance
Fidelity 401(k) plan with 4% employer matching
20 paid time off (PTO) days per year
