Incubated at IIT Madras, we are a deep-tech startup dedicated to designing and building the world's most compact electric flying taxi. Our mission is to make door-to-door flying a reality, drastically reducing commute times and decongesting our cities for a cleaner, greener future. We're a passionate team of engineers, designers, and visionaries working on cutting-edge technology, and we're looking for brilliant minds to help us take flight. Chart the Course for the Future of Flight We are looking for a Full-Stack Product Engineer to develop and test the user-facing operating system for tools we are building. You will build high-density, performant, and aesthetic web tools that turn complex computational physics, graphs, and dense engineering documents into intuitive, interactive workflows. You will design our UI system from the ground up and maintain the system to ensure a high-performance, real-time application dashboard. Our platform will handle high-throughput, real-time data flows so you will architect systems that can cleanly ingest processed high-velocity data and handle concurrent systems Roles andResponsibilities Establish the frontend architecture, state management patterns, and reusable component library designed for complex, data-heavy enterprise engineering applications Build responsive, low-latency interfaces across visualisers, automated document/artifact viewers/rich text editors Architect and maintain a robust backend API layer capable of multiplexing thousands of concurrent real-time events Build memory-efficient browser frontend for high-frequency data streams Establish clean CI/CD pipelines, robust unit/integration testing strategies for asynchronous code, and enforce strict API type schemas Connect tooling and pipelines between our partner software systems and our internal data systems Build the backend API layer and WebSocket pipelines that interface with our asynchronous simulation services, managing long-running computational jobs and large result datasets\nRequirements Required\nQualifications Proven track record of architecting and shipping complex, dense web applications (Visualisation heavy systems across developer tools, spatial/mapping software, financial trading terminals) Modern Web Stack: Mastery of TypeScript, React, and modern CSS/design system tooling (e.g., Tailwind CSS, Radix UI). Demonstrated experience with 2D/3D web visualization tools Ability to build and maintain clean, asynchronous APIs, WebSockets, background workers, and relational database schemas\nPreferred\nQualifications Experience with programmatic artifact generation Familiarity with node/graph-based UI frameworks (e.g., React Flow) for displaying complex dependencies and traceability. Background in engineering, CAD/CAM, simulation, or data-intensive B2B platforms. Foundational background or interest in low-level programming concepts (C/C++, memory management, or systems engineering). Experience utilizing HTML5 Canvas, WebGL, or SVG layout engines for rendering high-frequency graphics or spatial dashboards.","description_format":"text","description_chars":3165,"description_truncated":false,"requirements":{"experience_years_min":null,"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":["Smart Mobility","Aircraft Manufacturing"],"lifecycle":[{"event":"open","at":"2026-10-29T10:19:50Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":14,"expected_fill_days":91,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/the-eplane-company-full-stack-product-engineer","json_url":"https://alion.io/job/the-eplane-company-full-stack-product-engineer.json","meta":{"generated_at":"2026-11-02T12:15:01Z","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":16791,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":723173},"rest":"https://alion.io/mcp/rest/get_company?id=723173"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthe-eplane-company-full-stack-product-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%2Fthe-eplane-company-full-stack-product-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%2Fthe-eplane-company-full-stack-product-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/the-eplane-company-full-stack-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthe-eplane-company-full-stack-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3449335}},{"tool":"search_jobs","arguments":{"company":"eplane.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3449335},"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.
