We are looking for a Security Assurance Engineer to join a large-scale public-sector technology modernization initiative in Boston, MA. This is a contract opportunity with a hybrid schedule, requiring 3 days onsite per week for the first 90 days and 2 days onsite thereafter. The role will focus on application security, cloud security, vulnerability management, security testing, and release readiness across AWS, Salesforce, GitHub, Jira, Tenable, Veracode, and AI-enabled applications.

This is a great opportunity for a security engineer who wants to be involved throughout the full project lifecycle rather than coming in after the fact to review vulnerabilities. You’ll work directly with application, cloud, development, architecture, testing, and project teams to build security into two major modernization initiatives from design through deployment. The environment includes public-facing applications, cloud integrations, Salesforce, AI/LLM solutions, RAG pipelines, and sensitive data, giving you exposure to a wide range of modern security challenges. The ideal person will be hands-on, comfortable working independently, and able to communicate technical risk clearly to both technical and non-technical stakeholders.

Contract Duration: 6–12 Months, with the project currently running through June 2027 and potential for extension
