Job description
Leidos is searching for a highly motivated product tester to support Common Criteria evaluation efforts with Leidos’ Accredited Testing & Evaluation (AT&E) Laboratory. The ideal candidate is an independent performer who can perform commercial off-the-shelf (COTS) IT product security tests with minimal supervision, including devising product-specific test procedures and performing any configuration procedures necessary to enable the execution of tests. The candidate is also expected to interact with product developers and other technical staff to develop necessary product knowledge and assist in troubleshooting when tests cannot be successfully executed. General IT product knowledge such as networking, operating systems, communications security, identity and access management, and PKI is essential. This is a fast-paced position requiring time management skills to perform multiple product certification efforts in parallel and a thorough understanding of how product security requirements may apply to a wide variety of hardware and software products. The ideal candidate is also able to assist with setup and maintenance of laboratory infrastructure.
This position will be based in Columbia, MD. Part-time telework is acceptable but the selected candidate will be expected to be in-office for regular periods as needed to support efforts that must be performed locally. Therefore, only local candidates will be considered.
Primary Responsibilities:
Work with IT product vendors to determine applicability of IT product security standards to products
Interpret IT product security standards to determine the compliance or noncompliance of product design based on research of product documentation and interviews with technical personnel
Devise, execute, and document security functional testing to justify how tested products are compliant with IT security standards
Conduct product troubleshooting and provide recommendations when noncompliant findings are made
Conduct vulnerability research to determine if documented security vulnerabilities are adequately mitigated by product configuration and patch level
Produce documentation that describes how IT products conform to security requirements
Develop user guidance for instructions on placing products into secure configurations
Justify completeness, consistency, accuracy, and sufficiency of product test result to third-party quality reviewers
Assist in maintenance of the physical and digital infrastructure of the laboratory, including physical setup, server administration, backups, and patching
Basic Qualifications:
Bachelor s degree (or equivalent) and 4 years of related experience
Must have experience with network traffic and protocol analysis using products like Wireshark, TShark, or tcpdump to validate product compliance
Familiarity with general IT security products and their operation (e.g., routers/switches, firewalls, intrusion detection/prevention systems, operating systems, software applications, mobile devices)
General knowledge of the role that various IT products and concepts serve in information security (e.g., full disk encryption, mobile device management, remote access/VPN, etc.)
Experience with software development lifecycle methods (e.g., agile) and tools (e.g., Subversion, GitLab, Confluence, JIRA)
Strong applied knowledge of network, transport, and application layer communications and security (e.g., TCP/IP, TLS, IPsec, SSH, LDAP)
Working knowledge of applied cryptography (e.g. X.509, PKI, post-quantum standards)
Strong customer-facing oral and written communication skills
Preferred Qualifications:
Previous experience with Common Criteria certification or related standards (FIPS 140, FedRAMP, NIST SP 800-53) is desirable.
Software development or DevOps experience a plus.
Experience with administration of Windows/Linux systems and version control/ticketing systems (e.g., JIRA, GitLab, Subversion)
One or more technical professional certifications related to information technology communications or security (e.g., CEH, CCNA, CISSP)
Knowledge of scripting/programming (e.g., Python) and familiarity with machine-readable data exchange methods (e.g., JSON, REST)
Please note: while the salary range is wide, the specific salary range for this position is going to be around $120,000.
