Overview
Product software team is responsible for providing customer facing software that runs on our industry leading all optical network switch. The team manages two different software stacks running on different PCBs. The network software (NIC SW) implements various L2/L3 protocols and allows customers to communicate with the optical switch using interfaces such as TL1, Netconf, Restconf and WebUI. The control software (DSP SW) is a bare metal stack that receives user commands through NIC SW and controls the movement and position of piezoelectric actuators.
Key Responsibilities
- System Design and Architecture: Make significant contributions in an existing code base to add new features and enhancements working with the software architect and team lead. Document low level design aligned with the product architecture.
- Firmware Development: Develop, debug and optimize bare metal firmware for ARM based microcontrollers to ensure efficient and reliable operation of embedded systems.
- Hardware Collaboration: Work closely with hardware engineers to review schematics, develop and debug hardware drivers, and ensure seamless hardware software integration.
- Interface Implementation: Implement and optimize low level device interfaces such as UART, SPI, GPIO, ADC, DAC and I2C to facilitate communication between peripherals and microcontrollers.
- System Testing and Validation: Use advanced diagnostic tools and test equipment to validate and troubleshoot embedded systems, ensuring high quality and reliable performance.
- Agile Development Participation: Actively contribute to Agile development processes, including sprint planning, daily stand ups, and retrospectives, and generate and maintain relevant process artifacts.
- Continuous Improvement: Identify areas for improvement in existing systems and processes, propose innovative solutions, and drive continuous improvement initiatives.
- Documentation: Create and maintain comprehensive documentation for design specifications, code and system functionality, ensuring clear communication and knowledge sharing.
