Token

Systems Engineer

• Design, develop, debug, and maintain embedded firmware across the full lifecycle—requirements, architecture, implementation, test, and documentation.
• Read, understand, and apply component datasheets, reference manuals, and applicable standards (FIDO, JavaCard, and others) in Token designs.
• Monitor and optimize use of constrained system resources—CPU, memory (RAM/NVRAM), and I/O.
• Write clean, maintainable, well-documented code and participate in code reviews.
• Design schematics and lay out PCBs for new products and revisions of existing ones.
• Select components and manage the BOM for performance, availability, quality, and cost.
• Own hardware bring-up and hardware/software integration on new boards.
• Define hardware and software specifications together to ensure compatibility and performance.
• Test pre-production prototypes and diagnose issues spanning both hardware and software.
• Perform RF testing and board-level diagnostics using oscilloscopes, logic analyzers, and spectrum analyzers.
• Troubleshoot hardware faults—bad solder joints, design issues, marginal components—alongside general hardware and software debugging.
• Lead failure analysis on prototypes, returns, and production defects, persisting until root cause is determined and driving corrective action.
• Work directly with manufacturing and contract manufacturers to resolve production issues and improve yield.
• Ensure component and design decisions produce a high-quality, cost-effective, and manufacturable product.
• Collaborate across hardware, firmware, cloud, mobile, and manufacturing teams to align on product requirements and goals.
• Contribute to engineering processes, tooling, and best practices, and embrace AI tools to streamline development, documentation, and testing.
• Ensure compliance with applicable standards and regulations (e.g., ISO 13485, ISO 9001, FIDO, SOC 2).
