Job summary

Amazon Development Center U.S., Inc. in Arlington, VA seeks a Software Development Engineer to design, build, and operate a mission-critical, multi-tenant platform for managing large-scale fleets of embedded devices across highly secure environments.

The role emphasizes building cryptographic trust infrastructure, multi-tenant data isolation using ABAC, and tamper-evident logging, with focus on reliability, security, and compliance for AWS hardware/software solutions.

Qualifications

• Bachelor's degree in computer science or equivalent.
• 3+ years of non-internship design or architecture experience.
• 2+ years with C, C++, or Rust.
• Strong security-hardened system design experience (PKI, mutual TLS, signing).

• Current, active US Government Security Clearance of Top Secret with SCI eligibility or above.

Responsibilities

• Build and maintain cryptographic trust infrastructure supporting multiple certificate authority hierarchies with offline validation mechanisms suited to disconnected environments
• Implement multi-tenant data isolation using attribute-based access control (ABAC), row-level security, and transparent query rewriting — designed to scale from single-tenant to hundreds of tenants over a 5-year horizon
• Develop cryptographic integrity mechanisms for configuration and audit data, including chained signatures and append-only tamper-evident logging
• Engineer emergency access ("break-glass") workflows with time-bounded credentials, multi-party approval, and segregated audit trails
• Ensure all cryptographic operations leverage FIPS 140-2 Level 3 validated key management with strict key isolation boundaries
• Design reconciliation protocols where edge devices remain the recommended source of truth, with backend systems maintaining synchronized projections
