What is an RFI (Request for Information)?

RFIs, or Requests for Information, are formal documents used by organizations to collect information from potential suppliers or vendors before making procurement decisions. They help companies understand the capabilities, products, and services available in the market, and are often the first step in the procurement process. An RFI typically outlines the information needed and allows vendors to respond with their qualifications and offerings. This helps organizations make informed decisions about which suppliers to invite for further evaluation, such as through a Request for Proposal (RFP) or Request for Quotation (RFQ).

How does an RFI specialist typically collaborate with other departments during the procurement process?

An RFI specialist works closely with procurement, legal, technical, and project management teams to ensure that requirements are clearly defined and vendor questions are addressed accurately. Collaboration involves gathering input from stakeholders to prepare comprehensive RFI documents, reviewing vendor submissions, and facilitating communication between internal teams and potential suppliers. This cross-functional coordination is essential for aligning business needs with available solutions and ensuring a smooth transition to later procurement stages.

What are the key skills and qualifications needed to thrive as an RFI specialist, and why are they important?

To thrive as an RFI Specialist, you need strong analytical abilities, attention to detail, and expertise in information management, often supported by a background in business, engineering, or construction management. Familiarity with RFI tracking software, document control systems, and project management tools like Procore or Aconex is typically required. Excellent communication, organizational skills, and the ability to collaborate across teams are vital soft skills in this role. These competencies are crucial for ensuring accurate information flow, timely responses, and efficient project coordination.

Job description

Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions. We thrive on finding and cultivating talented people who are passionate about what they do. Join us and be a part of the diverse Caltech community.
Job Summary
We are seeking an Electromagnetic Compatibility (EMC) and Radio Frequency Interference (RFI) engineering specialist to work on the DSA-2000 project (https://www.deepsynoptic.org/), a world-leading telescope that is currently in the design phase. The array will use 2000, 5-meter dishes to observe at radio wavelengths (0.7 - 2 GHz frequency range) to survey the skies 10x faster than any radio telescope current or planned. The telescope will conduct a broad range of research, including the study of the formation of galaxies, the search for cosmic explosions, and investigations into the nature of gravity. The applicant would fulfill the role of an EMC specialist for the DSA-2000 project. This role will support the Lead Project Engineer and the management team to help make this project a reality as we progress through the final design stage to construction. Specifically, the EMC specialist will play a critical role in ensuring that the telescope system does not degrade the electromagnetic environment in which it is constructed.
The role can be based at either the Caltech campus or the Owens Valley Radio Observatory (OVRO, https://www.ovro.caltech.edu/), a world class facility operated by Caltech for research in radio astronomy, located near Bishop in central California on the ancestral homelands of the Big Pine Paiute Tribe of the Owens Valley. Remote work is acceptable, contingent on ability to effectively collaborate with colleagues at Caltech and OVRO. This role includes opportunities for growth through education and training as relevant or needed. The DSA-2000 project values diversity and inclusion and is committed to supporting our team members in any way possible. We encourage applicants who can bring a new perspective to the team.
Please contact the hiring manager, Mr. Francois Kapp (fkapp@caltech.edu), with any questions regarding this position.

  • Other duties related to EMC as assigned.

Basic Qualifications
  • An advanced degree in engineering with specialization in EMC.
  • Excellent knowledge of EMC and RFI standards, including for example ITU-R RA.769-2, CISPR 11, and FCC Part 15.

  • At least 5 years' experience working on EMC and RFI in an engineering development environment.
  • Excellent communication skills (in English), analytical skills, and problem-solving ability.
  • Ability to work collaboratively within an agile, multi-disciplinary and diverse team.

Preferred Qualifications
  • Hands-on experience with - and in-depth knowledge of - EMC and RFI mitigation in a radio astronomy environment.
  • At least 8 years' experience working on EMC and RFI in an engineering development environment for radio astronomy.
  • Scientific or background knowledge relevant to the DSA-2000 project (astronomy, radio astronomy, scientific software development, high performance computing, infrastructure).
