Harvey Site Reliability Engineer interview questions & guide 2026

The questions below represent the core competencies Harvey evaluates for Site Reliability Engineer candidates. While specific technical hurdles may shift based on your seniority—from Senior Software Engineer to Staff Site Reliability Engineer—the underlying focus remains on your ability to design resilient systems and solve complex production issues.

Systems Architecture and Scalability

These questions test your ability to design systems that can handle growth while maintaining strict uptime and performance standards.

• How would you design a highly available, multi-region architecture for an AI-driven service?
• What strategies would you implement to handle a sudden 10x spike in traffic to our core API?

Preparation at Harvey requires a blend of deep technical mastery and a clear, structured way of communicating your thought process. You should be prepared to dive into the "why" behind your technical choices, not just the "how."

Technical Depth and Domain Knowledge – You will be evaluated on your mastery of infrastructure, distributed systems, and cloud-native technologies. Interviewers look for candidates who can explain the internal mechanics of the tools they use and anticipate potential failure modes in their designs.

Architectural Thinking – You must demonstrate the ability to see the "big picture." This means evaluating trade-offs between performance, cost, and maintainability. When discussing system design, always articulate the constraints you are optimizing for and why.

Operational Maturity – Success in this role requires a proactive approach to reliability. You should be ready to discuss how you define, measure, and improve service-level objectives (SLOs) and how you foster a culture of blameless post-mortems and continuous improvement within your engineering teams.

The interview process at Harvey is designed to be rigorous, focusing on identifying engineers who possess both the technical depth to handle massive scale and the collaborative mindset to drive cross-functional reliability initiatives. You should expect a series of technical deep-dives that cover everything from low-level systems programming to high-level system architecture.

The pace is professional and efficient, with a heavy emphasis on your ability to work through real-world scenarios. Harvey values engineers who can communicate clearly under pressure and who demonstrate a deep, innate curiosity about how systems fail and how they can be made more resilient.

This timeline provides a high-level view of your journey from initial contact to final decision. Use this to pace your preparation, ensuring you dedicate enough time to both the theoretical design phases and the practical coding or debugging sessions. Note that for Staff-level roles, you should expect increased scrutiny on your ability to influence technical strategy and mentor junior engineers.

Distributed Systems Design

This area is critical for Site Reliability Engineer roles at Harvey. You are expected to demonstrate how you design systems that survive partial failures and scale horizontally.

Be ready to go over:

• Load balancing strategies – How you distribute traffic and handle congestion.
• Service discovery and orchestration – How your components find and communicate with each other.

As a Site Reliability Engineer at Harvey, your core mission is to bridge the gap between development and operations. You will be responsible for the full lifecycle of the company’s infrastructure, from initial design and capacity planning to incident response and post-incident remediation.

You will collaborate closely with product engineers to shift reliability "left," ensuring that performance and observability are built into the product from day one. You will also lead efforts to automate operational tasks, reducing toil and allowing the engineering team to focus on feature velocity. Typical projects involve enhancing the CI/CD pipeline, managing cloud infrastructure costs, and refining the monitoring and alerting stack to reduce noise and improve the signal-to-noise ratio during production incidents.

A strong candidate for Harvey brings more than just a list of technical skills; they bring a proven track record of managing complex environments.

• Must-have skills:

  • Deep experience with cloud-native infrastructure (e.g., AWS, GCP).
  • Proficiency in container orchestration, specifically Kubernetes.
  • Strong coding skills in languages like Python, Go, or Rust for building automation tools.
  • Experience with observability platforms (e.g., Prometheus, Grafana, Datadog).

• Nice-to-have skills:

  • Experience with AI/ML infrastructure and model serving platforms.
  • Contributions to open-source infrastructure projects.
  • Experience working in high-growth, fast-paced startup environments.

Q: How much time should I dedicate to preparing for the system design portion? A: Dedicate significant time to practicing architectural trade-offs. You should be able to articulate why you chose one approach over another, considering factors like latency, cost, and operational overhead.

Q: Is there a specific focus on AI infrastructure? A: Given Harvey's domain, understanding the unique reliability challenges of large-scale AI models—such as GPU utilization, model serving latency, and data pipeline integrity—will definitely set you apart.

Q: What is the most important trait for a successful candidate? A: Beyond technical skills, we look for "operational empathy"—the ability to understand the pain points of the developers you support and the impact of system failures on our end users.

• Think out loud: During technical sessions, narrate your thought process clearly. This allows the interviewer to understand your logic even if you hit a roadblock.
• Own your past failures: When discussing past incidents, focus on what you learned and how you improved the system's resilience as a result.
• Ask clarifying questions: Never jump straight into a solution; always clarify the requirements, constraints, and success metrics first.

The Site Reliability Engineer role at Harvey offers the rare opportunity to build the infrastructure that will define the future of the legal industry. By focusing your preparation on distributed systems architecture, operational automation, and clear, structured communication, you will be well-positioned to succeed.
