What is a computer software engineer?

Computer software engineers, also known as software developers, design, develop, test, and maintain software applications or systems that enable computers and devices to perform specific tasks. They use programming languages and engineering principles to create software solutions for a variety of industries, including technology, healthcare, finance, and more. Their work involves analyzing user needs, writing code, debugging, and collaborating with other professionals to deliver functional and reliable software products.

What are the key skills and qualifications needed to thrive as a computer software engineer?

To thrive as a Computer Software Engineer, you need strong programming skills, a solid understanding of algorithms and data structures, and typically a degree in computer science or a related field. Familiarity with development tools such as Git, integrated development environments (IDEs), and knowledge of frameworks or languages like Java, Python, or C++ are often required, along with certifications like AWS Certified Developer or Microsoft Certified: Azure Developer Associate. Excellent problem-solving abilities, teamwork, and effective communication distinguish top performers in this field. These skills are crucial for building reliable, scalable software solutions and collaborating efficiently within development teams.

What are some common challenges computer software engineers face when working on large-scale projects?

Computer software engineers working on large-scale projects often encounter challenges such as coordinating with cross-functional teams, managing complex codebases, and ensuring consistent communication throughout the development cycle. Keeping documentation up to date and maintaining legacy systems while integrating new features can also be demanding. Effective use of version control systems and agile methodologies helps engineers address these challenges and contribute to successful project delivery.

What is the difference between Computer Software Engineer vs Software Developer?

AspectComputer Software EngineerSoftware Developer
CredentialsBachelor's degree in Computer Science or related field; certifications like Microsoft Certified, AWS CertifiedBachelor's degree in Computer Science or related field; certifications optional
Work EnvironmentDesigning, developing, testing, and maintaining software systems; often involved in system architectureWriting, debugging, and implementing code; focused on application development
Industry UsageUsed across tech, finance, healthcare, and more for complex system developmentCommonly used in app and web development across various industries

Computer Software Engineers typically focus on designing and building complex software systems, often working on system architecture, while Software Developers mainly write and implement code for applications. Both roles require similar educational backgrounds and certifications, but their focus areas and responsibilities differ, with engineers handling broader system design and developers concentrating on coding tasks.

How much do computer software engineers get paid?

Computer software engineers typically earn a median annual salary ranging from $80,000 to $120,000, depending on experience, location, and specialization. Entry-level positions may start lower, while experienced engineers with skills in programming languages and development tools can earn higher salaries, especially in high-demand areas.

Job Description

Who You’ll Work With

Arista’s BIOS team is responsible for developing and maintaining the CPU firmware, BIOS and Boot Loader software used in all Arista products. This work includes bringing up new CPU boards, getting EOS to boot securely, efficiently and reliably. This work also involves designing and implementing new features in EOS to manage and secure the low level system initialization and booting subsystems, as well as keeping pace with the latest developments in the open source and proprietary BIOS development communities.

Arista BIOS software engineers are also responsible for low level software driving the CPU subsystems on all Arista products. You will evaluate new CPUs and work with CPU vendors and BIOS vendors to integrate their low level firmware into Arista products. You will work closely with hardware engineers to bring up, validate and test new CPUs in our hardware products.

Arista Software Engineering roles demand a strong and broad software engineering background. While the primary focus area for this role is firmware, BIOS and booting software, your work will cover all aspects of software development spanning the design and development of new features, debugging problems and fine tuning code for reliability 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

  • Design, develop, integrate and maintain the low-level CPU software in Arista products.
  • Develop automated tests using C, C++ and Python to validate your features.
  • Work with hardware engineers and vendors to qualify new CPUs and related components for use in Arista products.
  • Track ongoing developments in the Linux Kernel and identify features and functionality of interest to Arista for our products and for internal development needs.
  • Work with upstream open source BIOS communities to contribute features back to the mainline.
  • Review and contribute to functional and design specifications written by other engineers.
  • 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.
  • Provide technical leadership across features, projects and tools.
  • 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 + 8 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 6 years experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering + 3 years experience, or equivalent work experience
  • Expert knowledge of and extensive experience programming in C required. Knowledge of C++ and Python is desirable.
  • Experience designing and developing software in CPU firmware, BIOS and boot loader environments.
  • Experience bringing up new CPU boards.
  • Significant hands‑on experience diagnosing problems, troubleshooting issues, and fixing bugs in low‑level CPU firmware, BIOS and boot loader software.
  • Familiarity with Linux kernel architecture, design and implementation desirable
  • Understanding of IP networking architecture, design and principles desirable
  • Applied understanding of modern software engineering principles and practices
  • Strong problem solving and troubleshooting skills.
  • Strong software design and implementation skills.
  • Ability to work independently and in small teams.
  • Ability to communicate articulately, and document your designs and implementations clearly, and concisely.
  • Familiarity with and experience working with the x86 and ARM CPU architectures
