As part of our TS APAC Digital and Connected Commerce team, you'll be at the forefront of innovation-building scalable, AI-powered platforms that connect healthcare\nprofessionals with J&J products and ultimately improve patient outcomes at scale.\nRole Overview\nWe are seeking a Senior Full Stack Engineer who not only builds AI-powered applications but also leverages AI as a core part of their development workflow. This is a hands-on engineering role focused on delivering modern digital healthcare solutions using full stack technologies and Generative AI.\nYou will operate in a fast-paced, highly collaborative Agile environment, partnering with product, design, and business stakeholders to rapidly prototype, build, and scale impactful solutions.\nYou will play a key role in shaping how AI transforms both our products and the way we build software-including developer productivity, testing automation, and spec-to-code workflows.\nKey Responsibilities\nDesign, build, and maintain scalable web applications using Node.js, TypeScript, React, and/or Python.\nDevelop and maintain RESTful or GraphQL APIs and integrate third-party services.\nBuild responsive, accessible, and reusable UI components with modern UX patterns (e.g., real-time updates, streaming interfaces).\nDesign and manage data models using SQL and NoSQL databases.\nDeploy and operate applications in AWS, following best practices for scalability, reliability, and observability.\nWork with modern architectures including serverless, microservices, and containerized environments.\nIntegrate LLM APIs (e.g., OpenAI, Anthropic, Bedrock) into applications.\nBuild AI-driven features such as search, summarization, recommendation, and conversational\ninterfaces.\nUtilize frameworks such as LangChain, LangGraph, or similar orchestration tools.\nPrototype and evaluate new AI capabilities, rapidly iterating with an experimentation mindset toward production-ready, AI-first solutions.\nLeverage AI-assisted development (e.g., GitHub Copilot, Amazon Kiro, or similar) to accelerate coding, debugging, and testing.\nPractice AI-paired programming (human-in-the-loop development with LLMs; “vibe coding”), iterating with LLMs to rapidly prototype and refine solutions.\nApply spec-driven development, translating product requirements into structured prompts, schemas (e.g., OpenAPI/JSON), or executable specifications for AI-assisted implementation.\nUse AI for generating unit/integration tests, documentation, and code reviews to improve quality and velocity, with human validation and quality gates. \nContinuously evaluate and adopt emerging AI developer tools and workflows, with a focus on measurable improvements in developer productivity, code quality, and delivery speed.\nWrite clean, maintainable, and well-tested code.\nParticipate in code reviews, technical design discussions, and Agile ceremonies.\nCollaborate with cross-functional teams across business and technology domains.\nContribute to a culture of continuous improvement, experimentation, and learning.\nExperiences\nMust Have\n4-8 years of experience developing and deploying production-grade web applications.\nStrong full stack experience (frontend + backend) building scalable systems.\nExperience with cloud platforms (AWS preferred).\nHands-on experience integrating LLM APIs or AI-powered features into applications.\nFamiliarity with frameworks such as LangChain, LangGraph, or similar.\nExperience using AI-assisted coding tools (e.g., Copilot, Amazon, Kiro) in day-to-day development.\nExperience with prompt engineering and evaluation of LLM outputs.\nStrong understanding of modern software engineering practices (Git workflows, code reviews, CI/CD, Agile).\nExcellent problem-solving, debugging, and communication skills.\nGood to Have\nExperience with real-time systems (WebSockets, SSE, streaming APIs).\nExposure to containerization (Docker, Kubernetes) or serverless architectures.\nExperience with CI/CD and automation tools (e.g., Jenkins, Argo).\nExperience building mobile applications or PWAs.\nUnderstanding of performance optimization, scalability, and web security.\nWhat Sets This Role Apart\nThis role offers the opportunity to shape AI-native engineering practices and developer workflows within a global enterprise while operating with an experimentation mindset-from problem framing through prototyping, iteration, and scaling successful solutions. You will influence how AI is embedded into day-to-day engineering workflows, not just product features, and contribute to a culture that values continuous learning, curiosity, and GenAI fluency across teams, ultimately building solutions that directly impact millions of patients and healthcare professionals.\nRequired Skills:\nPreferred Skills:\nAgility Jumps, Analytical Reasoning, Coaching, Continuous Integration and Continuous Deployment (CI/CD) Pipeline, Critical Thinking, Full Stack Development, Human-Computer Interaction (HCI), Requirements Analysis, Software Architectures, Software Development Management, Software Engineering Practices, Software Quality Assurance (SQA), Tactical Thinking, Technical Writing, Technologically Savvy","description_format":"text","description_chars":6290,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Continuous learning"],"hiring_locations":[{"name":"Singapore","iso":"SG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Prescription Drugs","Surgical Instruments & Devices","Orthopedic & Spine Implants"],"lifecycle":[{"event":"open","at":"2026-10-21T14:10:43Z"}],"visa":[],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.471,"p_room":0.35,"age_days":18,"expected_fill_days":8,"reasons":["conf:19","stale_co","velocity","win:tail","comp:brand"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/johnson-johnson-senior-full-stack-engineer","json_url":"https://alion.io/job/johnson-johnson-senior-full-stack-engineer.json","meta":{"generated_at":"2026-10-27T04:34:56Z","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":4098,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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":14152},"rest":"https://alion.io/mcp/rest/get_company?id=14152"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjohnson-johnson-senior-full-stack-engineer"},{"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%2Fjohnson-johnson-senior-full-stack-engineer"},{"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%2Fjohnson-johnson-senior-full-stack-engineer"},{"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/johnson-johnson-senior-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjohnson-johnson-senior-full-stack-engineer"}]}
