Software Engineer II - Secure IoT Fleet Platform

Amazon Web Services (AWS); Jessup (MD); On-site; USD 144,000 - 194,000; Full time

Job summary

Amazon Development Center U.S., Inc. is seeking 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 enterprise networks.

This role sits at the intersection of distributed systems, security engineering, and fleet operations—building infrastructure that must meet the highest standards of reliability and compliance.

Qualifications

• Bachelor's degree in computer science or equivalent.
• 3+ years of non-internship design or architecture experience.
• 2+ years with at least one system programming language such as C, C++, or Rust.
• Strong background in security-hardened system design, including PKI, mutual TLS, and cryptographic signing.
• Proficiency with PostgreSQL or similar relational databases, including row‑level security and policy‑based access control.
• 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 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.
