We build the symbiotic partnership between developers and AI that makes shipping fast software safe again, reviewing every pull request, IDE change, and CLI commit so teams can move quickly without breaking things.\nWe are a fast-moving, well-funded company, fresh off a $143M Series C at a $1.5B valuation - building Agentic Change Management, the control layer for software changes created by humans and agents. As AI writes more of the world's code, the bottleneck moves from implementation to judgment and helping human judgment scale is exactly the problem we exist to solve.\nRole Overview\nAs 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.\nYou’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.\nResponsibilities\nArchitect and build scalable backend services, APIs, and distributed systems\n\nCollaborate with ML engineers to integrate models into agent-based systems and AI products involving autonomous or task-driven agents\n\nGuide junior engineers through mentorship and technical reviews\n\nOwn architectural decisions in new product features\n\nEnsure reliability, performance, and security across systems\n\nContribute to an engineering culture of speed, quality, and pragmatic innovation\n\nQualifications\nEducation: Degree in Computer Science, Engineering, Artificial Intelligence, or a related technical field, or equivalent practical experience\n\nExperience: 5+ years building backend systems and distributed infrastructure\n\nTechnical Expertise: Fluency in TypeScript and Node.js, or a similar modern backend stack; experience with micro services, async job queues, and event-driven architectures\n\nSystems Thinking: Familiarity with cloud platforms (AWS/GCP), containerization (Docker/Kubernetes), CI/CD pipelines, devops tooling, runtime infrastructure, and production observability\n\nEngineering Craft: Strong understanding of software engineering best practices, including testing, code reviews, and version control workflows\n\nProduct Mindset: Thoughtful about trade-offs, user experience, and fast iteration\n\nTeam Leadership: Willing to mentor, lead by example, and influence technical direction without being a pure manager\n\nBonus Points\nExperience with code search, code graphs, tree-sitter, or static analysis tools, and an understanding of how to apply them in real-world engineering environments\n\nExperience integrating AI/LLM-based systems into product workflows\n\nContributions to open-source or community projects\n\nExperience designing or implementing agent-based systems or AI products involving autonomous or task-driven agents\n\nWhy Join Our Engineering Culture?\nCodeRabbit 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.\n\nWe 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.\n\nOur 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.\n\nThis opportunity will beenergizing for people who want real ownership, pace, and high standards. It's uncomfortable for people who prefer slow consensus or heavily managed workflows.\n\nIf you want tobuild 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.\n\nOur Values\nCollaborative Humans: Prioritizing collective intelligence\n\nFearless Innovators: Turning obstacles into growth opportunities\n\nPersistent, Passionate Developers: Thriving on complex, long-term challenges\n\nImpact-Driven Creators: Crafting intuitive tools for developers\n\nRapid Learners and Un-learners: Adapting quickly in our fast-paced technological world","description_format":"text","description_chars":5024,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Growth opportunities"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-04-27T19:36:34Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 10","filings_12m":10,"filings_prev_12m":4,"green_card_filings_12m":0,"median_offered_wage_usd":230500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":5}],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.712,"p_room":0.36,"age_days":185,"expected_fill_days":98,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/coderabbit-senior-software-engineer-backend","json_url":"https://alion.io/job/coderabbit-senior-software-engineer-backend.json","meta":{"generated_at":"2026-10-30T11:43:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":16773,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":35010},"rest":"https://alion.io/mcp/rest/get_company?id=35010"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcoderabbit-senior-software-engineer-backend"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fcoderabbit-senior-software-engineer-backend"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fcoderabbit-senior-software-engineer-backend"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/coderabbit-senior-software-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcoderabbit-senior-software-engineer-backend"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":13397}},{"tool":"search_jobs","arguments":{"company":"coderabbit.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":13397},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
