• Strong proficiency in C/C++ (required) and Python (preferred)
• Experience developing production-quality APIs and software libraries
• Experience with cross-compilation, build systems, and packaging for embedded or SDK-based environments
• Familiarity with embedded Linux and/or RTOS environments, including debugging on target hardware
• Strong understanding of software architecture, modular design, and interface definition
• Experience working with hardware interfaces or embedded systems
• Proficiency with Git and general software development best practices
• Strong communication and collaboration skills for both internal and external-facing development

Nice To Haves

• Exposure to GNSS, PNT systems, or signal processing pipelines
• Experience with secure firmware or embedded security implementations
• Knowledge of applied cryptography concepts (e.g., encryption, authentication, key exchange)
• Understanding of secure system architecture and trust boundaries across distributed systems
• Experience implementing or integrating secure key provisioning, storage, rotation, or revocation workflows
• Understanding of network security protocols or secure communication stacks
• Experience working with third party SDKs, silicon vendors, or third-party embedded platforms
• Experience supporting manufacturing provisioning or secure device onboarding workflows
• Comfortable debugging across software-hardware boundaries in constrained environments
• Familiarity with Linux kernel/user-space interaction or driver-level debugging

Responsibilities

• Integrate and maintain secure decryption and authentication software across partner hardware platforms.
• Integrate software with partner SDKs and runs on external embedded hardware platforms
• Define and maintain APIs and interfaces for secure key handling, authentication, and data access
• Support integration across trust boundaries (internal backend, provisioning pipeline, partner receivers/simulators)
• Collaborate with internal teams and external partners to enable secure deployment, debugging, and validation on external hardware
• Work with product and engineering teams to ensure scalable, robust, and production-ready security architecture
• Assist in manufacturing and provisioning workflows for secure device onboarding
