1. What is a DevOps Engineer at Replit?

At Replit, the role of a DevOps Engineer—often aligned with Site Reliability Engineering (SRE)—is central to the company’s mission of democratizing software creation. You are not simply maintaining servers; you are building the "agentic" platform that allows millions of users to build, deploy, and scale applications using natural language. The infrastructure you design directly empowers the next generation of software builders, removing traditional barriers to entry.

In this position, you will bridge the gap between development and operations in a high-velocity environment. Replit operates with a "go fast" mentality, where innovation speed is paramount. Your job is to ensure that despite this velocity, the underlying systems remain resilient, scalable, and performant. You will work extensively with Kubernetes, GCP, and distributed systems to support over 500,000 business users and millions of developers globally.

This role requires a high degree of agency. You are expected to proactively identify reliability bottlenecks, architect observability solutions, and lead incident responses. Unlike traditional DevOps roles that may focus heavily on ticket-based operations, Replit expects you to apply software engineering principles to infrastructure problems, automating toil and creating self-healing systems that allow the product team to ship features aggressively without breaking the platform.

2. Getting Ready for Your Interviews

Preparation for Replit requires a shift in mindset. You need to demonstrate not just technical competence, but an alignment with a very specific, high-intensity engineering culture.

Key Evaluation Criteria

Deep Technical Proficiency You must demonstrate expert-level knowledge of distributed systems and container orchestration. Interviewers will probe your understanding of Kubernetes internals, cloud-native networking, and GCP services. You are expected to know not just how to use these tools, but how they work under the hood and how to tune them for high throughput and low latency.

Operational Maturity & Incident Management Replit values engineers who stay calm under pressure. You will be evaluated on your ability to lead high-impact incidents, conduct blameless post-mortems, and drive preventative measures. You should be able to discuss past failures in detail, explaining how you diagnosed the root cause and what systemic changes you implemented to prevent recurrence.

Automation & Coding Skills This is a software engineering role. You will be tested on your ability to write high-quality, well-tested code in Python or Go. The expectation is that you solve problems through automation and "Infrastructure as Code" (using tools like Terraform or Pulumi) rather than manual intervention.

Cultural Alignment & Agency Replit has a distinct culture driven by strong "Operating Principles." You will be assessed on your autonomy ("High Agency"), your bias for action, and your willingness to work in a "go fast" startup environment. Interviewers are looking for candidates who read and understand the company’s ethos—often described in public writings by leadership—and can navigate a workplace where culture is explicit and codified.

3. Interview Process Overview

The interview process at Replit is rigorous, challenging, and often described as "open to interpretation." The company avoids cookie-cutter questions in favor of scenarios that test your critical thinking and adaptability. The process typically moves quickly, reflecting the company’s operational velocity.

You will generally start with a recruiter screen to discuss your background and alignment with Replit's mission. This is followed by a technical screen, which may involve a coding challenge or a systems discussion. If you pass, you will move to an onsite loop (usually virtual) comprising multiple rounds. These rounds are split between deep technical dives—focusing on debugging, architecture, and coding—and behavioral interviews that heavily scrutinize your alignment with the company's "Operating Principles."

Candidates often report that the technical questions are less about memorizing algorithms and more about practical application in distributed environments. You might be given a vague problem statement and asked to design a solution, testing your ability to handle ambiguity. The behavioral components are equally significant; the team wants to ensure you can thrive in an autonomous, high-intensity environment.

The timeline above illustrates the typical flow from application to offer. Note that the "Onsite" stage is the most intensive portion, often consisting of 4-5 back-to-back sessions. Use the time between the technical screen and the onsite to deep-dive into Replit's public engineering blog and cultural manifestos.

4. Deep Dive into Evaluation Areas

To succeed, you must prepare for specific technical domains that are critical to Replit's stack. The interviews will push you to the limit of your knowledge in the following areas.

Infrastructure & Orchestration

This is the core of the role. You need to demonstrate a mastery of Kubernetes and GCP. Expect questions that go beyond basic deployment. You should be able to discuss scheduling logic, networking models, resource isolation, and scaling strategies for multi-tenant clusters.

Be ready to go over:

• Kubernetes Internals – Etcd consistency, controller patterns, and CNI/CSI plugins.
• Capacity Planning – Autoscaling strategies (HPA/VPA) and spot instance management.
• Container Security – Isolation techniques (gVisor, Kata Containers) which are relevant to Replit’s "code execution" product.

Observability & Debugging

Replit needs engineers who can find needles in haystacks. You will likely face a "debugging" interview where you are presented with a broken system or a performance regression and must identify the root cause.

Be ready to go over:

• Telemetry Design – Implementing tracing (OpenTelemetry), metrics (Prometheus), and structured logging.
• SLOs/SLIs – How to define meaningful reliability targets for product teams.
• System Linux Fundamentals – Using strace, tcpdump, and eBPF to diagnose kernel-level issues.

Coding & Automation

Unlike some Ops roles, you cannot rely solely on Bash scripting. You will be asked to write production-grade code.

Be ready to go over:

• Tooling Development – Writing CLIs or Kubernetes operators in Go or Python.
• Infrastructure as Code – Advanced state management in Terraform or Pulumi.
• CI/CD Pipelines – Designing secure, high-velocity build and deploy systems.

System Design

You will be asked to design systems that scale to millions of users. These questions are often open-ended.

Be ready to go over:

• Global Distribution – Reducing latency across global regions.
• State Management – Designing reliable storage layers for distributed applications.
• Resiliency Patterns – Circuit breakers, rate limiting, and load shedding.

The word cloud above highlights the most frequently discussed topics in Replit DevOps interviews. Notice the heavy emphasis on Kubernetes, System Design, and Culture. This confirms that while technical skills are non-negotiable, your ability to design scalable systems and fit into the company culture is equally weighted.

5. Key Responsibilities

As a DevOps Engineer (or Staff SRE) at Replit, your day-to-day work is a mix of high-level architecture and deep-dive engineering. You are responsible for the health of the infrastructure that powers the entire platform.

Your primary focus will be to architect and implement observability solutions. You will design the systems that provide real-time visibility into the health of the platform, enabling the team to detect issues proactively before they impact users. This involves not just installing tools, but defining the strategy for logging, tracing, and metrics across the organization.

You will also lead incident management. When things break—and in a high-growth environment, they will—you act as the senior leader, guiding the team to rapid resolution. Post-incident, you are responsible for the "repair" phase, writing code and automation to eliminate the class of failure entirely.

Collaborating with product teams is essential. You will optimize performance on Kubernetes, helping developers tune their applications for the cloud.
