The Product Software Team are responsible for providing customer facing software that runs on our industry-leading all-optical network switch. The team are responsible for managing 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 the desired interfaces that includes 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.
The Senior Software Engineer is responsible for enhancing and optimising Polatis products, focusing on software architecture, design, integration, and ensuring seamless collaboration across cross‑functional teams. This role involves hands‑on technical contributions, mentorship, and aiding in the overall growth and efficiency of the software development team.
Software Architecture and Design
Collaborate closely with the Software Architect to shape both system design and test pass criteria for all assigned projects, ensuring cohesive alignment with product architecture, user requirements, and technical constraints.
Technical Expertise
The role involves developing software in C for Linux-based embedded systems, contributing to the user‑space software stack to enhance product functionality. It requires close collaboration with quality engineers to design and review software verification plans, as well as analysing test outcomes to identify improvement opportunities. The position also includes investigating customer-reported bugs, identifying root causes, and delivering effective fixes to uphold product quality and customer satisfaction.
Hardware Integration
Utilise hands‑on experience to integrate software with hardware, comprehending various hardware protocols (I2C, UART, SPI, USB) and reading hardware schematics effectively.
Cross‑Functional Collaboration
Collaborate with cross‑functional teams to define project scopes and contribute to planning and estimation of work packages. Collaborate with production, NPI, and customer support teams to address potential software issues during production and in the field, ensuring timely resolution.
Process Orientation
Produce the relevant project artefacts as required by the software development process. Provide specific documentation related to product design to meet regulatory compliance and organization requirements.
