Job Description

Who You’ll Work With

As a Layer1 _software_ engineer, you will get to work on _software_ that manages the physical layer, where packets meet the outside world. Stable and reliable physical connectivity is critical for any network and that is your challenge. You will get to write control _software_ that brings to life everything from the ubiquitous 1GBASE-T connectors to _400G_ long reach optics that provide fiber connectivity across continents. Your _software_ will need to work across a wide variety of _forwarding_ engines, connectors and interface chips called gearboxes, which allow our hardware platforms to support diverse physical connectivity options within a product family. You will build instrumentation and telemetry tools that track physical link health parameters reported by the Layer1 components and enable operators to monitor and troubleshoot their links effectively. You will also work closely with our Optics teams to define standards for new media and bring them to market.

Arista _Software_ Engineering roles demand a strong and broad _software_ engineering background. While the primary focus area for this role is Layer1 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.

Arista _Software_ Engineering prides itself on a supportive and growth oriented culture. Over time, as your interests change, coupled with evolving business needs you will have the opportunity to _switch_ from Layer1 to other areas, if you like.

What You’ll Do

• Interface with customers, product management and hardware engineers to come up with innovative new Layer1 features.

• Architect, design and manage the 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 to test the features.

• Work with hardware and manufacturing teams to bring new Layer1 components like 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 for those problems.

• Mentor new and junior engineers to bring them up to speed in Arista’s _software_ development environment.

Qualifications

• BS Computer Science/Electrical Engineering/Computer Engineering + 3 years experience, or equivalent work experience

• 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

• Ability to design a solution and implement features independently.

• Ability to work in small teams.
