Mariatu Tejan, Contract Specialist

Mariatu Tejan serves as a Contract Specialist at the Securities and Exchange Commission, where she plays a critical role in executing complex acquisitions that support the agency’s mission of market integrity and investor protection. She manages the full lifecycle of procurement actions for mission-critical systems, including data analytics platforms, cybersecurity infrastructure, financial surveillance tools, and technical consulting services. Her work directly enables the SEC’s ability to monitor market activity, detect illicit trading patterns, and enforce federal securities laws through advanced technological capabilities. Tejan typically handles both fixed-price and cost-reimbursement contracts, often involving high-complexity IT modernization and systems integration efforts. Tejan maintains consistent working relationships with a select group of top-tier federal contractors, including General Dynamics Information Technology, Booz Allen Hamilton, Maximus Federal Consulting, Team Greenzone JV, and Procentrix. These partnerships reflect a preference for vendors with deep expertise in financial data analytics, regulatory technology, and enterprise-scale system modernization. Her procurement approach emphasizes proven performance, technical maturity, and demonstrated experience in highly regulated environments, fostering long-term vendor collaborations that ensure continuity and scalability of critical SEC systems. Tejan’s contracting activity is exclusively non-set-aside, with 100% of her awards issued under full and open competition. This reflects a strategic focus on accessing the broadest possible pool of qualified vendors with specialized capabilities in financial market surveillance and data intelligence, rather than socioeconomic set-asides. While small business participation is not a primary driver in her portfolio, her acquisitions remain fully compliant with federal acquisition regulations and emphasize merit-based selection. Her procurement focus centers on IT services, systems integration, and analytical platform development, aligning with NAICS categories such as 541512 (Computer Systems Design) and 541611 (Administrative Management Consulting). She routinely procures cloud-based data repositories, algorithmic trading surveillance tools, AI-driven anomaly detection systems, and cybersecurity frameworks tailored to financial market infrastructure. Her domain expertise lies at the intersection of financial regulation and advanced data analytics, ensuring the SEC’s technological posture remains robust and adaptive.
