Senior Software Engineer, Platforms - Sydney

Who You’ll Work With

As a member of our Platforms team, you'll be at the critical intersection of hardware and software. We write the essential control software that brings our physical switches to life, managing everything from Ethernet PHYs and fan controllers to FPGAs and complex NICs. Your code will form the foundational hardware abstraction layer (HAL), ensuring system stability and health monitoring across all Arista product families. In our team, you'll own your work from definition to deployment, solving challenging low-level problems that have a high-level impact.

Arista Software Engineering roles demand a strong and broad software engineering background. While the primary focus area for this role is Platforms software, the role will cover all aspects of software development spanning the addition of new features, debugging problems and fine tuning code for scalability and performance. You will own your projects from definition to deployment and customer interactions, and you will be responsible for the quality of everything you deliver.

What You’ll Do

• Architect and Develop: Design and develop embedded software in C/C++ and Python to manage and control hardware components on Arista's switching platforms.

• Collaborate: Work closely with product management, hardware, software and FPGA engineers to define optimal software control interfaces and participate in the board bring-up process for new products.

• Own Quality: Build robust automated tests and test infrastructure to validate platform features and ensure hardware components function correctly across a wide variety of platforms.

• Lead and Mentor: Provide technical leadership across features and projects, contributing to design specifications and mentoring junior engineers.

• Customer Engagement: Work directly with Customer Support Engineers and customers to analyze, mitigate, and fix complex hardware-related software issues in the field.
