## Description

· Contributes to the transition of an existing XML-based Key Server to an object-based architecture supporting certificates, cryptographic keys, tokens, and other protected secrets.

· Develops object models, secure and versioned APIs, object-level operations, synchronization between ground and aircraft environments, access control, error handling, auditing, and system integration.

· Designs reliable software for distributed environments with intermittent connectivity while maintaining security, compatibility, performance, and operational resilience.

· Researches, designs, develops, integrates, and maintains secure Linux-based software supporting key management and object-based security services for connected aircraft systems.

MAJOR RESPONSIBILITIES:

· Designs, modifies and implements software applications from functional and system design specifications.

· Codes, integrates, tests, debugs, and refines the software to produce the required product.

· Develops software tools and subsystems to support software development, test, and reuse, and manages their implementation.

· Enhances software to reduce operating time or improve efficiency and robustness.

· Reviews, evaluates, and analyzes design interfaces and specifications.

· Maintains the developed software efficiently through solid knowledge of software lifecycles.

· Documents designs in engineering documents including functional block diagrams and data/logic flow charts.

· Designs object-based data models for certificates, cryptographic keys, tokens, secrets, metadata, versioning, lifecycle state, and access-control information.

· Develops secure, versioned REST and/or gRPC APIs for object creation, retrieval, update, deletion, synchronization, and lifecycle operations.

· Integrates established encryption, decryption, key-wrapping, certificate, and secret-management mechanisms without changing approved cryptographic algorithms, key sizes, or signature schemes.

· Prepares and reviews architecture, interface, design, requirements, test-plan, and test-procedure documentation.

· Implements centralized logging, monitoring, audit trails, and end-to-end traceability for object access, synchronization, lifecycle, and error events., We use AI tools to support parts of our hiring process, such as reviewing applications and identifying potential matches. These tools are designed to promote efficiency, consistency, and fairness, and they are always used under human oversight.
