Who You’ll Work With
As a Layer1 software engineer you will develop software that manages the physical layer, ensuring packets meet the outside world. Your challenge is stable and reliable physical connectivity. You’ll write control software for devices ranging from 1GBASE‑T connectors to 1.6T long‑reach optics, support diverse forwarding engines, gearboxes, and interface chips, and build instrumentation and telemetry tools to monitor link health. You will also work closely with our Optics teams to define standards for new media and bring them to market.
Layer1 is the primary focus, but the role covers all aspects of software development—from adding new features, debugging, and fine‑tuning code for scalability and performance. You will own projects from definition to deployment, customer interactions, and be responsible for the quality of everything you deliver.
Over time, as your interests evolve and business needs change, you may switch from Layer1 to other areas if interested.

- Architect, design and manage development of these features.
- Develop and maintain features using C, C++ and Python, review and contribute to functional and design specifications, build automated tests and test infrastructure.
- Work with hardware and manufacturing teams to bring new Layer1 components such as PHYs and transceivers to market.
- Collaborate with hardware engineers to design optimal software‑control interfaces for managing Layer1 components.
- Provide technical leadership across features, projects and tools.
- Work with Customer Support Engineers and customers to analyze, mitigate and fix problems in customer networks.
- Work with the System Test Engineers to analyze problems found in their tests and provide fixes.
- Mentor new and junior engineers in the Arista software development environment.
Qualifications
- BS in Computer Science/Electrical Engineering/Computer Engineering + 8 years experience, or MS + 6 years experience, or Ph.D. + 3 years experience, or equivalent.
- Expert knowledge of C or C++ and Python.
- Knowledge of UNIX or Linux.
- Knowledge of digital communication technologies like modulation and signal encoding schemes is a plus.
- Understanding of IP networking and/or distributed systems is a plus.
- Experience working with low‑level hardware components is a plus.
- Applied understanding of software engineering principles.
- Strong problem‑solving and software troubleshooting skills.
