## Description (the employer's text)

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation.

### About Replit

Replit is building the world’s most ubiquitous AI coding agent. Replit Agent can be used by anybody to bring their ideas to life. Whether it’s an app for yourself, the next great startup idea, or a tool to make you more productive at work, Replit Agent can help build it. Replit is also the leader in secure vibe coding. We protect apps, give users features to manage security risks, and help them vibe code more safely.

### About the Role

In this role you will build powerful tools that help product engineers iterate rapidly on the Agent experience and directly enhance the core Agent itself. You’ll bridge the gap between the AI team (working on the core Agent logic) and the UX team (crafting delightful Agent experiences), enabling both groups to excel within their specialties.

This role blends systems engineering, developer experience and product engineering. We tackle complex challenges across the full stack, from browser-based interfaces to high-performance backends to Linux systems engineering. We’re looking for engineers who have a keen sense of the product experience and how to power it with performant systems.

On this team, you’ll have the opportunity to grow your skills across our infrastructure and product, and to lead end-to-end efforts with meaningful impact. We value diverse perspectives and encourage candidates from all backgrounds and experiences to apply.

### You Will

Build high-throughput backend applications and services, like streaming chat between user and agent.

Design a collaborative "Multiplayer Computer" that lets humans and AI agents work together on shared shells, filesystems, and state—conflict-free and in real time.

Develop infrastructure (frontend & backend) that empowers product engineers to rapidly ship delightful user experiences.

Design and build durable, well-crafted interfaces between the Agent and internal systems, as well as external agentic systems (MCP)

### Required Skills and Experience

8+ years professional experience in building backend services, systems and platforms

Someone who values simplicity and pragmatism—you think radically but ship incrementally.

Self-directed and comfortable working autonomously.

Collaborative and team-oriented with a strong sense of shared ownership.

### Preferred Qualifications

Experience across the full-stack.

Experience building AI powered tooling or products.

Experience with collaborative editing technologies such as Operational Transforms (OT), CRDTs, or the inner workings of Git.

Experience with event sourcing systems.

### What We Value

Problem-solving mindset: Ability to approach complex operational challenges systematically and devise effective solutions

Self-directed and autonomous: Capable of working independently while collaborating effectively with cross-functional teams

Strong communication skills: Ability to explain complex technical concepts to both technical and non-technical audiences

Continuous learning: Passion for staying current with industry best practices and new technologies

Focus on automation: Strong belief in automating repetitive tasks and building self-healing systems

This is a full-time role that can be held from our Foster City, CA office. The hybrid role has an in-office requirement of Monday, Wednesday, and Friday.
