Electrical Engineer

RdF Corporation is a leading precision sensor company specializing in the design, qualification, and manufacture of high-reliability sensors for demanding aerospace, energy, defense, and research applications. Founded in 1955 and located in Hudson, NH, our products serve critical environments where performance and accuracy are non-negotiable.

RdF Corporation seeks an Electrical Engineer to support both existing product lines and the development of next-generation sensor solutions. The ideal candidate thrives in a hands-on engineering environment, is comfortable owning projects from concept through production, and can collaborate effectively with external researchers, suppliers, and customers to deliver precision measurement solutions.

• Lead electrical engineering projects from initial concept through design, prototyping, validation, and production release.
• Support and improve existing sensor product lines, including design modifications, failure analysis, and process optimization.
• Design and develop analog and digital circuits for precision measurement applications, including signal conditioning, data acquisition, and sensor interface electronics.
• Create, execute, and document prototype builds and engineering test plans; analyze results and iterate designs accordingly.
• Collaborate with outside researchers, universities, and industry partners on advanced sensor development programs.
• Manage vendor and supplier relationships for electrical components and subassemblies; evaluate and qualify new sources as needed.
• Develop and maintain engineering documentation including schematics, BOMs, test procedures, and design specifications.
• Contribute to firmware or embedded software development for sensor systems where applicable.
• Support manufacturing engineering by providing guidance on assembly, test, and inspection of electrical assemblies.
• Ensure designs comply with applicable standards and regulatory requirements (e.g., MIL-SPEC, IPC J-STD, 10CFR50).
• Other duties as assigned.

• Bachelor’s degree in Electrical Engineering or closely related field required; advanced degree a plus.
• Experience with analog circuit design, particularly for precision measurement, low-noise amplification, or sensor signal conditioning.
• Demonstrated ability to manage a project independently from requirements definition through execution and delivery.
•  Hands-on experience designing and testing prototypes; comfortable with iteration and working in a lab environment.
• Proficiency with test and measurement equipment including oscilloscopes, data acquisition systems, multimeters, and spectrum analyzers.
• Experience working with external partners such as research institutions, contract manufacturers, or component vendors.
• Proficiency with CAD software (e.g. Solidworks) and  PCB design tools (e.g., Altium, KiCad, or equivalent).
• Strong technical writing skills; ability to produce clear and complete engineering documentation.
• Experience in a regulated or quality-managed environment (AS9100, ISO 9001, or similar) is preferred.
• Candidates must be available to work M–F, be at least 18 years old, and able to pass a drug test.
• Must be authorized to work in the U.S.
• We offer competitive compensation packages and meaningful opportunities for professional growth. If you are a motivated engineer looking to contribute to precision technology that matters, we would love to hear from you.

RdF Corporation has been a trusted sensors manufacturer located in Hudson, NH since 1955. Our high-reliability and high-accuracy sensors are used in aerospace, defense, energy, and research applications worldwide, where measurement precision is critical to mission success.
