Real time sync via PubSub, bulk updates, image suppression.\nAI Mode Conversational AI interface: intent detection, knowledge-based replies, DB-querying, action execution, content publishing.\nReport Engine Event-driven pipeline: EventBridge Lambda SQS parallel processors S3 SES email delivery. Zero polling, zero crons.\nNotification System Fan-out architecture: coordinator Lambda sharded workers per channel SQS queues push/email/in-app delivery at scale.\nCompetitor Intelligence Data aggregation using RapidAPI, Google Places, and custom crawlers for competitive analysis.\nRequirements:\n2-5 years of professional full-stack development with Node.js and React in production environments.\nStrong CS fundamentals: data structures, algorithms, system design, API design patterns.\nDemonstrable experience using AI tools to accelerate development; show us your workflow, not just a resume.\nShipped features that handle real traffic at scale (10K+ requests/minute or equivalent).\nB. Tech/B. E. /MCA in Computer Science or equivalent practical experience.\nComfortable with ambiguity, fast iteration, and high ownership. You don't wait for perfect specs.\nGood to Have:\nNode.js (4+ years): Express/Hapi/Fastify, REST API design, async patterns, error handling, middleware architecture. You can build a production API from scratch.\nReact (3+ years): Hooks, state management (Redux/Zustand/Context), component architecture, performance optimisation, SSR/Next.js .\nDatabases: MySQL/PostgreSQL (query optimization, indexing, migrations) and MongoDB/DynamoDB. You can write an EXPLAIN plan and fix a slow query.\nCloud and DevOps: AWS (Lambda, SQS, SNS, S3, EventBridge, API Gateway), CI/CD pipelines, Docker, PM2.\nAI coding tools: Active user of Claude Code, Cursor, GitHub Copilot, v0, or similar. You use AI to scaffold, refactor, debug, and write tests.\nVibe coding: You can take a product brief, describe the intent to an AI assistant, iterate on the output, and ship a working feature in hours.\nLLM integration: Experience calling OpenAI/Anthropic/Groq APIs from backend code. Built features using LLMs for summarisation, classification, or generation.\nGit and testing: Branch strategy, PR workflows, unit tests (Jest/Vitest), integration tests. You write tests because you've been burned by not writing them.\nBonus: TypeScript, event-driven architecture (Kafka/SQS), Redis, Elasticsearch, WebSocket, OpenTelemetry/APM, MCP server development, multi-tenant SaaS architecture.","description_format":"text","description_chars":2730,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T05:30:33Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":18,"reasons":["seen:1","win:early"],"computed_at":"2026-10-08T05:49:30Z"},"pay":null,"html_url":"https://alion.io/job/singleinterface-full-stack-developer","json_url":"https://alion.io/job/singleinterface-full-stack-developer.json","meta":{"generated_at":"2026-10-09T00:47:59Z","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","counted_by":"address","units_charged":1,"used_today":1148,"day_limit":5000,"remaining_today":3852,"minute_limit":60,"resets_at":"2026-10-10T00:00:00Z"}},"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":3906432},"rest":"https://alion.io/mcp/rest/get_company?id=3906432"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsingleinterface-full-stack-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%2Fsingleinterface-full-stack-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%2Fsingleinterface-full-stack-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/singleinterface-full-stack-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsingleinterface-full-stack-developer"}]}
