Viasat Site Reliability Engineer interview questions & guide 2026

The following questions are representative of the technical and behavioral themes reported by candidates. While your specific experience may vary depending on the team, these patterns highlight what Viasat interviewers prioritize when assessing technical depth and practical problem-solving.

Technical and Domain Expertise

These questions test your proficiency with the core stack used to maintain Viasat infrastructure. Expect to dive into the "how" and "why" behind your technical choices.

• How would you design a CI/CD pipeline to ensure high availability for a mission-critical service?
• Describe your experience with container orchestration and how you manage container lifecycles in production.

Preparation for Viasat should be rooted in demonstrating your ability to handle real-world operational challenges. You should move beyond theoretical knowledge and focus on articulating the impact of your past work.

Technical Proficiency – You must be comfortable discussing the internals of Linux, networking, and cloud platforms. Interviewers look for candidates who can explain not just how to use a tool, but how that tool integrates into a broader, automated ecosystem.

Operational Mindset – Viasat values engineers who think about the long-term health of a service. You should demonstrate a strong grasp of automation, monitoring, and incident response, showing that you prioritize sustainable solutions over temporary patches.

Communication and Collaboration – Given the collaborative nature of SRE work, you will be evaluated on how you communicate technical risks to stakeholders. Be ready to articulate your decision-making process clearly, even when under pressure.

The interview process at Viasat is designed to evaluate both your technical depth and your alignment with their operational culture. Candidates typically navigate an initial screening phase followed by a more intensive onsite or virtual loop. The process is rigorous and focuses on gathering evidence of your ability to solve engineering problems in real-time.

You should expect the process to be comprehensive, involving multiple interactions with the engineering team. The focus remains on your practical experience; interviewers will often ask you to deep-dive into the specific architecture of projects you have led or contributed to. Maintain a professional demeanor throughout, as the team places high value on collaborative problem-solving.

This timeline illustrates the progression from initial screenings to the technical deep-dive sessions. Use this to pace your study, ensuring you have enough time to brush up on both core technical skills and your behavioral narratives. Remember that the number of interviewers can vary, so be prepared to adapt to different technical styles during the technical rounds.

Automation and Infrastructure

Automation is the heart of the SRE role at Viasat. You are expected to demonstrate how you have moved away from manual tasks toward scalable, repeatable processes.

• CI/CD Pipelines – Ability to design and maintain automated deployment flows.
• Configuration Management – Proficiency in tools like Ansible to manage fleet-wide settings.
• Containerization – Experience with Docker and orchestrators in production environments.

As a Site Reliability Engineer, your primary objective is to guarantee the uptime and performance of Viasat's service assurance systems. You will spend a significant portion of your time automating infrastructure, which involves writing scripts and utilizing configuration management tools to ensure consistency across environments. You will also participate in incident response, taking the lead on diagnosing complex issues and performing deep-dive post-mortems to prevent recurrence.

Collaboration is essential. You will work closely with software developers to ensure that new features are "production-ready" before they launch. This involves setting up monitoring, defining alerts, and participating in architecture reviews to identify potential failure points early in the development cycle. You are the bridge between the code being written and the service being delivered to the customer.

A competitive candidate for the Site Reliability Engineer position will possess a mix of operational experience and coding proficiency. Viasat looks for individuals who can manage the complexity of their network infrastructure while maintaining a focus on continuous improvement.

• Must-have skills: Deep knowledge of Linux administration, strong scripting skills (e.g., Python), experience with CI/CD workflows, and hands-on experience with cloud-based infrastructure (e.g., AWS).
• Nice-to-have skills: Experience with infrastructure-as-code tools, container orchestration platforms, and large-scale distributed system monitoring.
• Experience level: A proven track record in an SRE, DevOps, or systems engineering role, with specific examples of managing production services at scale.

Q: How difficult are the technical interviews at Viasat? A: The technical rounds are considered moderately difficult, focusing heavily on your practical application of skills rather than abstract theory. Be prepared to explain the "why" behind your technical decisions in previous roles.

Q: What is the best way to prepare for the onsite interview? A: Focus on your past projects. Be ready to explain the architecture of the systems you have worked on, the specific challenges you faced, and how you used automation to solve them.

Q: How long is the typical interview process? A: The process can be lengthy, involving several stages of screening and technical assessment. It is important to maintain consistent communication with your recruiter throughout the process.

Q: Does Viasat prioritize culture fit? A: Yes, Viasat values engineers who are proactive, collaborative, and communicative. During interviews, demonstrate how you work within a team, especially during high-pressure situations like outages.

• Own your failures: If asked about a technical mistake, focus on what you learned and the specific automation you implemented to ensure it never happened again.
• Prepare for ambiguity: You may be given open-ended system design questions; always start by asking clarifying questions to understand the requirements before proposing a solution.
• Know your tools: If you mention a tool like Ansible or Python on your resume, be prepared to discuss its advanced features or how you have used it to solve non-trivial problems.

The Site Reliability Engineer role at Viasat is a high-impact position that offers the opportunity to work on critical infrastructure at a global scale. By mastering the core technical requirements—specifically Linux, CI/CD, and cloud automation—and preparing clear, impact-focused examples of your past work, you will position yourself as a strong candidate. Remember that your ability to communicate your problem-solving process is just as important as your technical skill.
