You may come from one of those ecosystems, or from Flutter, native iOS/Android, or another modern application development background.\nWhat matters most is your ability to reason about problems, learn unfamiliar technologies quickly, choose the right tools for the job, and deliver great user experiences.\nWe work in an AI-enabled engineering environment, so we are looking for someone who knows how to use AI tools effectively — not simply for code completion, but to explore solutions, learn new platforms, prototype quickly, debug problems, and move from a goal to a working product.\nStrong logical and abstract thinking is one of the most important qualities for this role.\nWhat You'll Do\nOwn problems, not just tickets: Take product goals and turn them into practical technical solutions.\n\nBuild across our UI stack: Work with React, React Native, Angular, and other technologies when they are the right fit for the problem.\n\nUse AI as an engineering tool: Use AI to accelerate research, implementation, debugging, prototyping, testing, and learning.\n\nMove between technologies when needed: Become productive in unfamiliar frameworks, libraries, APIs, or platforms without being constrained by your existing stack.\n\nCraft excellent user interfaces: Build polished, intuitive, responsive interfaces with strong attention to interaction details and user experience.\n\nMake good architectural decisions: Break complex problems into understandable abstractions and choose solutions with appropriate trade-offs.\n\nTake features from idea to production: Contribute throughout the lifecycle, including implementation, testing, deployment, monitoring, and iteration.\n\nCollaborate across the stack: Work with APIs and backend services when required to deliver complete product features.\n\nRaise the engineering bar: Share knowledge, improve development practices, and help the team find better ways to build software.\n\nWhat We're Looking For\nStrong software engineering fundamentals and experience shipping production applications.\n\nExcellent logical, analytical, and abstract thinking skills.\n\nAbility to understand an unfamiliar problem, decompose it, and independently work toward a solution.\n\nStrong experience in at least one modern application development ecosystem, ideally including React, React Native, or Angular.\n\nExperience in Flutter, native iOS, native Android, or another comparable web/mobile platform is also highly relevant.\n\nAbility and willingness to learn new technologies rather than being attached to a particular framework.\n\nStrong understanding of application architecture, state management, APIs, asynchronous systems, and testing.\n\nExperience creating high-quality user interfaces, with attention to usability, visual polish, responsiveness, and interaction design.\n\nPractical experience using modern AI-assisted development tools as part of your engineering workflow.\n\nStrong TypeScript, JavaScript, or comparable programming-language fundamentals.\n\nAbility to work independently and take ownership from an ambiguous problem through to a finished result.\n\nHow We Think About AI\nAI is becoming part of how software is built.\nWe don't measure engineers by how much code they can type manually. We care about whether they can understand a problem, reason about possible solutions, use the tools available to them, validate the result, and deliver something that works well.\nYou should be comfortable using different AI tools and models where they are useful — whether that means exploring an unfamiliar API, generating a prototype, understanding an existing codebase, debugging an issue, evaluating approaches, or accelerating implementation.\nThe important skill is knowing what you are trying to achieve and being able to judge whether the result is actually good.\nNice to Have\nExperience working across both web and mobile products.\n\nExperience with more than one of React, React Native, and Angular.\n\nFull-stack experience with APIs, databases, distributed systems, or backend TypeScript.\n\nExperience establishing CI/CD and automated testing workflows.\n\nProduct or UX sensibility beyond pure implementation.\n\nExperience rapidly prototyping new product ideas.\n\nExperience integrating native platform capabilities.\n\n.NET experience.\n\nRxJS or functional programming experience.\n\nAbout Our Team\nWe have a strong engineering team and currently build user interfaces with React, React Native, and Angular.\nWe are looking for engineers who are comfortable operating beyond the boundaries of a single technology stack. The ideal person can understand a goal, reason about the problem, learn whatever is necessary, and use modern tools — including AI — to deliver a high-quality result.\nThis role offers significant ownership and the opportunity to influence how we build web and mobile products, how we use AI in engineering, and how we approach product development as a team.\nTech stack\nReact\nAngular\nTypeScript\nReact Native\nUX/UI\nHTML\nCSS\nResponsive Web Design (RWD)\nWCAG","description_format":"text","description_chars":5269,"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":["Transport Infrastructure","CAD, PLM & BIM Software"],"lifecycle":[{"event":"open","at":"2026-10-08T22:59:03Z"}],"visa":[],"liveness":{"score":81,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.806,"p_room":1,"age_days":8,"expected_fill_days":26,"reasons":["seen:8","win:early"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":92100,"is_top_pay":false},"html_url":"https://alion.io/job/invarion-senior-webmobile-developer","json_url":"https://alion.io/job/invarion-senior-webmobile-developer.json","meta":{"generated_at":"2026-10-17T14:18:02Z","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":19191,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":699704},"rest":"https://alion.io/mcp/rest/get_company?id=699704"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Finvarion-senior-webmobile-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%2Finvarion-senior-webmobile-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%2Finvarion-senior-webmobile-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/invarion-senior-webmobile-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Finvarion-senior-webmobile-developer"}]}
