Senior Software Engineer - Backend

Software EngineerCodeRabbit is an innovative research and development company focused on building extraordinarily productive human-machine collaboration systems. Our primary goal is to create the next generation of Gen AI-driven code reviewers: a symbiotic partnership between humans and advanced algorithms that significantly outperforms individual engineers. We combine language models with human ingenuity to push the boundaries of software development efficiency and quality.Role OverviewAs a Software Engineer at CodeRabbit, you'll be contributing to the development of advanced applied AI systems that revolutionize code review processes. You'll work at the intersection of intelligent systems and software engineering, creating tools that empower developers to iterate rapidly in complex environments. Your expertise will be crucial in developing solutions that enhance code quality, scalability, and developer productivity.You'll help architect and build core backend systems — the infrastructure that powers our AI agent workflows, context-enriched code reviews, repo-level planning tools, and dashboard interfaces. You'll work alongside AI researchers, infra specialists, frontend engineers, and product thinkers to build reliable, intelligent backend systems that power our developer tools at scale.ResponsibilitiesArchitect and build scalable backend services, APIs, and distributed systemsCollaborate with ML engineers to integrate models into agent-based systems and AI products involving autonomous or task-driven agentsGuide junior engineers through mentorship and technical reviewsOwn architectural decisions in new product featuresEnsure reliability, performance, and security across systemsContribute to an engineering culture of speed, quality, and pragmatic innovationQualificationsEducation: Degree in Computer Science, Engineering, Artificial Intelligence, or a related technical field, or equivalent practical experienceExperience: 5+ years building backend systems and distributed infrastructureTechnical Expertise: Fluency in TypeScript and Node.js, or a similar modern backend stack; experience with micro services, async job queues, and event-driven architecturesSystems Thinking: Familiarity with cloud platforms (AWS/GCP), containerization (Docker/Kubernetes), CI/CD pipelines, devops tooling, runtime infrastructure, and production observabilityEngineering Craft: Strong understanding of software engineering best practices, including testing, code reviews, and version control workflowsProduct Mindset: Thoughtful about trade-offs, user experience, and fast iterationTeam Leadership: Willing to mentor, lead by example, and influence technical direction without being a pure managerBonus PointsExperience with code search, code graphs, tree-sitter, or static analysis tools, and an understanding of how to apply them in real-world engineering environmentsExperience integrating AI/LLM-based systems into product workflowsContributions to open-source or community projectsExperience designing or implementing agent-based systems or AI products involving autonomous or task-driven agentsWhy Join Our Engineering Culture?CodeRabbit is building the next generation of AI-native developer tooling — starting with code review. We combine large language models with deep software engineering context to help teams ship faster, catch more bugs, and make better architectural decisions at scale.We are a high-ownership engineering culture. That means no passive execution, no waiting for perfect tickets, and no narrowly defined task boundaries. Engineers here find problems before they're assigned, use AI as a core part of how they build, ship with judgment, and own outcomes from proposal to production.Our operating philosophy: bias toward action, ship the smallest necessary coherent slice, validate proportional to risk, watch what happens, and make the system better. AI drafts; humans decide. Speed matters, but so does understanding what you ship.This opportunity will be energizing for people who want real ownership, pace, and high standards . It's uncomfortable for people who prefer slow consensus or heavily managed workflows.If you want to build tools that are changing how software gets written, and be held to the standard that the best engineers thrive under; we'd love to talk.Our ValuesCollaborative Humans: Prioritizing collective intelligenceFearless Innovators: Turning obstacles into growth opportunitiesPersistent, Passionate Developers: Thriving on complex, long-term challengesImpact-Driven Creators: Crafting intuitive tools for developersRapid Learners and Un-learners: Adapting quickly in our fast-paced technological world
