Company Description
Sigma Inc. is a boutique professional staffing agency and executive search firm founded in 1994 that connects organizations with high-caliber talent across the United States. Headquartered in Marlborough, Massachusetts, the company specializes in IT and healthcare staffing solutions while also supporting biotech and life sciences, higher education, creative design and publishing, administrative and finance, engineering, and government programs. Sigma delivers flexible engagement models that include contract/contingent, contract-to-hire, direct hire, and statement of work (SOW) project-based solutions, complemented by staff augmentation, executive search, and workforce transitioning. For clients seeking scalable programs, Sigma can partner through MSP ecosystems, provide RPO support, and offer Employer of Record/payrolling services, all underpinned by robust credentialing and compliance. In healthcare, Sigma places both clinical and non-clinical professionals nationwide and understands the distinct licensure, onboarding, and documentation needs of hospitals and health systems. Its life sciences practice has supported pharmaceutical R&D and clinical trials, sourcing specialists in areas such as antibody production, cell proliferation, and biochemical purification. Technology and engineering teams benefit from Sigma’s ability to staff software development, data, infrastructure, and UX/UI talent, while media and publishing clients leverage specialists in digital content and user experience. The firm partners with higher education institutions to fill instructional, administrative, and technology roles, and supports public sector entities at state and regional levels as either a prime contractor or subcontractor. With decades of experience and relationships spanning more than 42 states, Sigma focuses on transparent communication, speed, and precision—matching candidate skills, motivations, and lifestyle with client culture and requirements. This relationship-first approach, supported by modern tools and streamlined processes, enables Sigma to deliver timely shortlists, reduce hiring risk, and help clients build resilient teams while guiding candidates toward roles where they can thrive.
