It owns architecture, code quality, delivery standards, and production readiness, including reviewing, testing, debugging, and correcting AI-generated and manually written code, mentoring engineers, and collaborating with product, UX, specialists, and clients to deliver scalable, high-performance experiences. You will combine deep React expertise with practical backend capability and the ability to implement solutions independently of AI.\nResponsibilities:\nLead full-stack architecture and development; evaluate cross-layer dependencies and trade-offs, and align implementation plans with existing architecture\nDefine and enforce coding standards, design patterns, and clean, maintainable development practices\nEnsure performance, security, accessibility, and scalability standards are met\nManage React upgrades and framework updates as needed\nApply SDD: clarify requirements with product, business analysis, UX, and engineering; review measurable acceptance criteria, edge cases, and non-functional requirements. Contribute plans and tasks, supply repository context and guardrails to approved AI tools, and implement in reviewable increments. Keep specifications, code, and tests aligned and follow approval gates\nReview human- and AI-generated frontend, backend, and data-access code for business logic, specification alignment, security, maintainability, dependencies, and test adequacy. Combine automated evidence with judgment; approve only explainable, validated changes. Mentor developers in SDD, AI use, and review practices\nTranslate UI/UX designs into responsive, high-quality React interfaces\nDiagnose issues across browser, APIs, services, databases, and deployments using logs, traces, and reproducible tests. Validate AI-proposed fixes and make targeted corrections\nOwn unit, component, integration, API, and end-to-end testing using Jest, React Testing Library, or equivalents. Test acceptance criteria, negative paths, authorization, data integrity, and non-functional requirements. Independently verify generated code and test assertions; enforce CI/CD quality and security checks before merge\nCollaborate across teams and stakeholders; work directly with clients on technical decisions and issue resolution\nStay current with front-end technologies and industry practices; share knowledge and drive continuous improvement \nTechnical Qualifications:\nExperience in SQL and relational databases, including schema design, relationships, constraints, transactions, indexes, and migrations; reviewing generated queries and data-access code for correctness, integrity, performance, and safe parameters; and using NoSQL where required\nExperience in designing, implementing, integrating, and reviewing REST APIs in at least one backend stack, such as Node.js/TypeScript or equivalent, including validating contracts, inputs, authentication, authorization, business rules, and error handling, and independently correcting generated backend code\nExperience in React.js with strong expertise in functional components, hooks, context, and performance optimization; TypeScript, JavaScript (ES6+), HTML5, CSS, and styling with CSS-in-JS, Tailwind, or similar\nExperience in working hands-on with npm, Yarn, pnpm, or Bun\nExperience in state management using Redux or Zustand\nFamiliarity with Next.js or a similar React framework is a plus\nExperience in using Git proficiently, including focused pull requests and peer review, versioning specifications and implementation artifacts, linking code and tests to acceptance criteria, and updating artifacts as requirements or designs change\nExperience in practical AI-assisted development with GitHub Copilot, Cursor AI, or equivalents for code, tests, and documentation, including supplying requirements, context, constraints, and acceptance criteria; reviewing plans and output; refining specifications; correcting code; escalating when needed; and following approved-tool, confidentiality, credential, dependency, and agent-permission policies. SDD workflow competence is essential; familiarity with Spec Kit or equivalent is desirable\nExperience in frontend team or technical leadership, including reviews, decisions, and mentoring; coordinating end-to-end delivery; reviewing cross-stack changes; explaining trade-offs; and seeking specialist review beyond personal expertise\nUnderstanding of Angular, Vue.js, or other JavaScript frameworks sufficient to review code and support teams beyond React\nKnowledge of CI/CD, environment configuration, secrets, deployment validation, logging, monitoring, and rollback. Micro-frontends and cloud-hosted frontend deployments on AWS, Azure, or GCP are a strong plus \nPersonal Skills:\nTranslate business needs into scalable solutions; identify ambiguities, missing criteria, edge cases, and unsupported assumptions. Challenge AI recommendations and justify decisions with engineering principles and validation evidence\nExplain technical decisions clearly to technical and non-technical stakeholders\nEvaluate alternatives and use logical analysis to validate solutions\nLearn quickly, work independently and collaboratively, and manage competing tasks and deadlines\nEducation and Work Experience:\nOver 5 years of experience or an equivalent combination of education and experience, with demonstrated delivery across React, backend services, and databases. Show architectural judgment, correction of unfamiliar or generated code, and validation against acceptance criteria through project evidence or a practical exercise\nA background in CS, IT, or a related scientific discipline is preferred","description_format":"text","description_chars":5762,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-11-06T10:32:50Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":40,"reasons":["conf:3","win:early"],"computed_at":"2026-11-06T23:01:55Z"},"pay":null,"html_url":"https://alion.io/job/creative-capsule-react-js-senior-developer","json_url":"https://alion.io/job/creative-capsule-react-js-senior-developer.json","meta":{"generated_at":"2026-11-06T23:01:55Z","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":1891,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":9327},"rest":"https://alion.io/mcp/rest/get_company?id=9327"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcreative-capsule-react-js-senior-developer"},{"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%2Fcreative-capsule-react-js-senior-developer"},{"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%2Fcreative-capsule-react-js-senior-developer"},{"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/creative-capsule-react-js-senior-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcreative-capsule-react-js-senior-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3862737}},{"tool":"search_jobs","arguments":{"company":"creativecapsule.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3862737},"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.
