We’ve been doing this since 2015, and more than 1,500 companies have hired engineers through us.\nNew roles for senior AI engineers come in all the time, and several are open right now.\nTwo ways to work with clients\nContract: most roles are contract-based. You join the client’s team and work as part of it.\nDirect hire: some clients hire engineers full-time, and we support you through the process.\nBecause companies trust our vetting, applying through Lemon.io is often a shortcut. You get to the client faster than going through their full hiring process on your own.\nWhat you get\nCompetitive rate, based on your seniority and skills\nWe find the projects. No client hunting or rate negotiations. We match you manually based on your skills and preferences.\nFlexible schedule. Work async or with a small overlap with the team’s hours.\nNo micromanagement, no screen trackers\nDirect work with clients, most of them with technical backgrounds\nOngoing support from your application through every project, plus a community of engineers from [75+] countries\nWho we’re looking for\nAI Engineer:\n3+ years of commercial experience applying AI to practical technology solutions\nA solid understanding of Python is a must; experience with other programming languages commonly used in AI is a plus\nExperience with Vector Databases, Pinecone or Weaviate is required\n2+ years of experience with LangChain is mandatory\n2+ years of experience with large language models (LLMs) or vLLMs is mandatory\n2+ years of experience with RAG or OpenAI is required\nAI Agent Architect:\n3+ years of experience with Python\n3+ years of experience with LLM\nExperience with Multi-agent systems architecture, AI agent orchestration, AI telemetry is a must.\nAI Automation Architect:\n1+ year of experience with Workflow Automation and Webhooks\n3+ years with SQL is a must\nFamiliarity with AI API integration and Claude Cowork is a must\nKnowledge of Make.com/n8n/Zapier\n\nYou own problems end-to-end: you spot the issue, design and build the solution, and ship it to production\nYou can show the business impact of your work with concrete results (e.g., faster processing, lower costs, more users, fewer incidents)\nAdvanced English: you discuss business tasks, explain your decisions, raise issues early, and present yourself and your results well on client calls\nYou work full-time remotely and deliver without supervision\nYou onboard quickly and start shipping in your first weeks\n\nHow it works\nApply and complete your profile\nVerify your role\nOnce approved, we match you with a project. Typical time to first project: 3 weeks\nReady? Apply and join the Lemon.io community.\n\nNOT YOUR TECH STACK?\nWe're placing Senior Developers (4+ yrs commercial experience) across Site Reliability Engineering, Platform Engineering, Enterprise Software Engineering, React & Python, React & Golang, Golang, React & Java, React & Ruby, Ruby, PHP & Vue, Vue & Node.js, React & .NET, Android & iOS, iOS & Swift, Flutter & Firebase, Solutions Engineer, Blockchain (Ethereum/Ethers.js/Wagmi/Viem/Solana), Angular & Node.js, Vue & .NET, Python & Vue, DevOps, MLOps, Data Science, Angular & PHP, Angular & .NET, Symfony & React, Symfony & Vue, Symfony & An gular, Python, Symfony & JavaScript & Next.js & TypeScript, Data Analysis, React & PHP, Data Engineering, Project Management, Product Management, QA Automation, QA Manual, Embedded Software Engineering, React Native & Node, React Native & React, React Native & Ruby, React Native & Python, WordPress, Android, Angular, Python & Node, React & Node.js, Node & TypeScript, Java & Spring, Svelte & Python, Svelte & Node.js, Svelte & TypeScript, Rust, Shopify & JavaScript, Vue & Nuxt, PHP & Laravel, UI/UX Design, Animation, Graphic Design, React & Node & React Native, .NET & C#, Electron, Scala, C++, Unreal Engine & C++, Python & LLM, Unity, or Machine Learning Engineering and more.
