Full-Stack App Developer (AI Products)

Dubai-based | Mostly Remote | Contract | Deliverable-basedABOUT THE ROLESCALR is looking for a hands-on developer who knows how to build and ship products in a startup environment, including products that use AI as a core part of the user experience.We are looking for someone who can take an idea, understand what needs to be built, make sensible technical decisions, build it, integrate the right AI capabilities, deploy it and keep improving it.Ideally, you have built apps yourself, worked in small startups, freelanced on complete products, or been one of only a few developers responsible for getting a product from idea to real users.You will work directly with the founder on new digital products, starting with a consumer application currently being developed in Dubai.AI will be an important part of these products. You should be comfortable deciding where AI adds real value, selecting appropriate models or services, integrating them into the application, and building the surrounding product logic required to make the result reliable and useful.The work will be mostly remote, but you must be based in Dubai and available for occasional in-person meetings when useful.This is initially a contract role. Work will be organised around agreed deliverables rather than fixed office hours.You will have significant ownership over how products are built.WHAT YOU WILL DOBuild mobile-first web applications and PWAs from concept to productionWork across frontend, backend, databases and APIsTranslate product ideas and requirements into working softwareMake practical architecture and technology decisionsIntegrate AI models and APIs into real product workflowsWork with LLMs, multimodal models, image understanding, structured extraction and similar AI capabilities where relevantBuild prompts, model interactions, validation logic and fallbacks around AI outputsCombine AI with structured data, business rules and recommendation logicEvaluate different AI providers and models based on quality, speed and costBuild authentication, user accounts, payments and third-party integrationsSet up deployment, monitoring and product analyticsDebug and solve problems independentlyUse modern AI development tools to build faster and more effectivelyIterate quickly based on product feedback and real user behaviourAI EXPERIENCE IS IMPORTANTThis is not simply a developer role where using Cursor or another AI coding assistant counts as AI experience. We are specifically looking for someone who has integrated AI into applications used by real users.That could include experience with:OpenAI, Anthropic, Google Gemini or similar model APIsLLM-powered application featuresMultimodal AIImage recognition and image understandingOCR and document extractionStructured data extraction from unstructured inputsAI-assisted search or recommendationsTool calling and agent-style workflowsRetrieval and contextual AI experiencesPrompt and output evaluationManaging unreliable model responsesCost, latency and model-selection tradeoffsCombining deterministic application logic with probabilistic AI outputsYou do not need to be an AI researcher or train foundation models from scratch. You do need to understand how to turn existing AI capabilities into reliable product features.THE KIND OF DEVELOPER WE WANTYou have probably worked in a startup, built your own product, freelanced on complete applications, or been part of a very small development team.You are comfortable being the person who says:“I can build that.”And then actually gets it into production. You do not need someone else to handle every backend task, deployment issue, API integration, AI integration or technical decision.You know when something needs a robust solution and when a simple solution is enough for the current stage of the product. You are comfortable working with incomplete information, asking the right questions and moving forward without waiting for a perfect specification.Most importantly, you have personally shipped real applications and have practical experience integrating AI into products.TECHNICAL EXPERIENCEYou should have strong practical experience with several of the following:React and/or Next.jsTypeScript / JavaScriptResponsive web application developmentBackend development and APIsSQL and relational databases such as PostgreSQLPlatforms such as SupabaseAuthentication and user managementCloud deploymentGit and modern development workflowsAI APIs and LLM integrationsMultimodal AI or computer vision APIsProduct analytics and monitoringAI-assisted development tools such as Codex, Claude Code, Cursor or similarExperience with native mobile applications, payments, OCR, recommendation systems or structured extraction is useful.We care more about your ability to build complete products than whether you match a specific technology checklist.WHAT WE WILL ASK YOU ABOUTWe want to understand what you personally built, not only what the company or development team built.Be ready to show us one or more applications and explain:What was the product?What did you personally build?How big was the team?Which parts did you own yourself?Which AI capabilities did you integrate?Which models or providers did you use?How did you handle unreliable AI outputs?What technology did you choose and why?How did you deploy and operate it?What problems did you run into?What would you build differently today?Side projects, your own startups and independently built products absolutely count.HOW WE WORKSCALR works with founder-led AI and technology product companies in the UAE. We work practically, move quickly and avoid unnecessary complexity.For this role, that means:Direct access to the founderMostly remote workOccasional meetings in DubaiClear deliverablesSignificant technical ownershipShort feedback loopsAI as part of the product, not just part of the development processDecisions based on what the product actually needsComfortable working independently without relying on a large specialist development teamThis role will suit someone who enjoys building more than managing development.CONTRACTThis will start as a contract engagement based around agreed product deliverables. If the relationship works well and the products develop as expected, the scope can grow significantly over time.Applicants must currently be based in Dubai.HOW TO APPLYApply directly through LinkedIn.Please include examples of applications or products you have personally built. GitHub, App Store, Google Play, live products, portfolio links or private demonstrations are all relevant. Please highlight any products where you personally integrated AI functionality.
