Senior Software Engineer Chitra

Location: Fort Eustis (On-site Preferred) Clearance : Active Secret with TS Eligibility Overview Chitra is seeking a highly experienced Senior Software Engineer to assume technical ownership of a mature, data-intensive production application following a recent team transition. Full-Stack Systems Ownership | Data-Intensive Application | Security-Conscious Engineering This system includes: A sophisticated React/TypeScript frontend used for data analysis and visualization A polyglot backend composed of Python (FastAPI), Rust services, and Node/TypeScript components Application-layer security responsibilities (RBAC enforcement and permission propagation) Backend services that execute complex graph algorithms in addition to serving API endpoints The development team is responsible for application-level security and authorization logic, including implementing and enforcing role-based access control (RBAC) across services. Due to full team turnover, this role requires strong technical depth, systems thinking, and the initiative to operate independently with minimal onboarding support. This is a high-impact ownership role. Responsibilities Application Ownership Assume primary ownership of a multi-service production application Rapidly develop architectural clarity across frontend, backend, and service boundaries Reconstruct undocumented system flows and security assumptions Frontend (Data-Intensive) Maintain and enhance a complex React/TypeScript frontend Manage sophisticated client-side state (Zustand) Optimize rendering and memory usage for large datasets Maintain graphing and visualization components Debug performance bottlenecks and correctness issues Backend & Algorithms Maintain backend services in Python (FastAPI), Rust, and Node/TypeScript Support services executing complex graph algorithms Collaborate with a retained data scientist on algorithmic implementations Diagnose cross-service integration issues Application-Level Security Implement and maintain RBAC logic within a Node.js service Ensure consistent permission enforcement across backend services Identify and mitigate security gaps at the application layer Validate correct interpretation of authorization rules across system boundaries Operational Stability Maintain Docker/Docker Compose environments Improve observability and reduce operational friction Make pragmatic improvements without destabilizing production Core Technology Stack Frontend React TypeScript Vite Tailwind CSS Storybook Zustand Jest / React Testing Library Backend Python (FastAPI) Rust (custom services) Node.js / TypeScript services Complex graph algorithm execution Relational SQL database Infrastructure (Application-Level) Docker Docker Compose Nginx / OpenResty (Lua-based request logic) Required Qualifications 7+ years of professional software development experience Strong experience building complex React/TypeScript applications Experience managing non-trivial client-side state and performance-sensitive UIs Experience implementing or maintaining RBAC or authorization logic Experience building backend APIs in Python, Node.js, or similar Comfort working in polyglot backend environments Experience reasoning about cross-service security and permission enforcement Solid SQL knowledge and performance awareness Experience working in Dockerized environments Demonstrated history of inheriting and stabilizing complex systems Ability to operate independently without structured mentorship Strongly Preferred Experience working with graph algorithms or data-processing systems Experience collaborating with data scientists in production environments Experience with Rust in production Experience stepping into projects after full team turnover Experience documenting and reconstructing architecture in low-context environments What Success Looks Like Quickly understands system-wide data flow and permission models Identifies inconsistencies in authorization enforcement Improves frontend performance under large dataset load Stabilizes algorithm-backed services without overengineering Documents security assumptions and system boundaries Operates as the trusted technical owner of the application layer What This Role Is Not Not a basic UI development role Not backend-only API maintenance Not a cloud infrastructure position Not a mentorship-heavy environment Not a greenfield build This is a systems-level ownership position requiring technical depth, security awareness, and strong independent execution.
