Every organization runs on three things: the projects it's driving, the knowledge it keeps, and the requests it fields. Plane brings all three into one open, adaptable platform: simple enough for any team to adopt, dependable enough for organizations to build on. And we are building it for a future where humans and AI agents do that work together.\nPlane began in public on GitHub at the end of 2022. Since then it has grown into a work management platform used by teams around the world: 55,000+ stars, 5,000+ forks, and a contributor community that reads our code and files our issues. Organizations run Plane as a managed Cloud service, on their own infrastructure, or inside fully isolated environments. Building in the open keeps us close to users and raises the standard for everything we ship.\nPlane is the #1 work infrastructure in aerospace, defense, financial services, and other regulated industries: organizations whose requirements for control, auditability, and data residency rule most software out. When the strictest buyers pick a system of record, that choice means something. Adoption is growing fastest on Plane Cloud and in sovereign clouds, deployments that keep everything inside a country's own borders and rules.\nPlane is backed by top investors and built across San Francisco, London, and Hyderabad. We work in tightly knit teams, stay close to users, and care about the visible product as much as the unglamorous details that make software dependable. People own problems end to end, and we add process only when it helps the work.\nHumans and agents\nWe believe the next decade of work will be done by humans and AI agents together. Not agents replacing people, and not a chat window bolted onto software built for humans clicking around, but both working in one system of action, where an agent's work is as visible and as accountable as a person's.\nMost software treats AI as a feature. We treat agents as a kind of worker, and that changes what the system underneath has to be. Agents are only as good as the context they can see and the state they are allowed to change, so shared context, explicit state, durable history, and accountable action are not items on our roadmap. They are the product. Plane is built so that when an agent acts, the humans responsible can see what happened, why, and on whose authority, and the record survives.\nThis is what the infrastructure is for: making the future where humans and agents work together useful, legible, and fully within the organization's control. Every role at Plane is some part of building that.\nAbout the role\nPlane's mobile app runs against whichever server the person holding the phone chose, which might be Plane Cloud or a self-hosted instance several releases behind, on a device their IT department has locked down. It carries most of the web product, and it is where the work reaches people: whatever happens to a work item or a page, whether a colleague or an agent did it, shows up in the app and in notifications the moment it happens. You will own feature areas end to end, from the interface down to the native code underneath, and you will hold the architecture that keeps an app this size consistent. You will work with backend, design, product and QA engineers in San Francisco and Hyderabad, alongside the mobile developers who built what you are extending.\nWhat you'll do\nOwn feature areas end to end, from the interface through the data layer into the native code underneath, starting with scoped ones and taking on larger ones as you learn the app.\n\nBuild every feature to the same architecture. It is written down and it is not optional, which is what lets anyone on the team open any part of the app and know where the state, the data and the interface live.\n\nOwn the native surface on both platforms: home screen widgets in WidgetKit and Jetpack Glance, quick actions, method channels, and the background work that keeps a widget and the app in agreement without costing the person their session.\n\nOwn how the editor feels on a phone. Plane's editor is built by our editor team and renders inside a fork of InAppWebView, so making it behave like part of the app rather than a page inside one is yours, in their codebase as much as ours.\n\nOwn how work reaches a phone: push notifications, notifications inside the app, the inbox, catch up, and the activity that people and agents generate on items and pages.\n\nWork daily with backend, design, product and QA across San Francisco and Hyderabad, writing the test scenarios for each platform that QA gates the release on and raising coverage in the code you touch.\n\nShip against several server versions at once. Working out what a feature does on a self-hosted instance three releases behind is tedious, and it will make you good at designing for software that upgrades on someone else's schedule.\n\nWhat you'll bring\nYou have shipped and maintained Flutter apps in production. Not only to launch, but through the releases and regressions that came after.\n\nYou architect for whoever arrives after you. Clean architecture and SOLID are already how you work, and you can walk us through a codebase you structured and what you would change now.\n\nYou understand state management as a pattern, not a library. Unidirectional flow, how events become state, and where side effects belong. We use Bloc.\n\nDependency injection is a habit, not a package choice. You can describe your composition root and how you swap implementations in tests.\n\nYou write unit and widget tests while you build. Point us at one that caught something real before a user did.\n\nYou match the codebase you are in. Our patterns are written down, and we would rather a feature look like the rest of the app than like your preference.\n\nNice to haves\nYou have written native code on Android and iOS to make a Flutter feature possible.\n\nYou have worked on apps built around webviews and have opinions about bridging JavaScript and Dart.\n\nYou have shipped with Bloc, or maintained a Flutter package or fork that other people depend on.\n\nYou have built local caching and persistence layers, and arrived at your opinions about invalidation the hard way.\nYou have shipped into self-hosted, regulated or otherwise locked down environments where you control neither the server nor the device.\n\nTech\nMobile: Flutter, Dart, Bloc, GoRouter\n\nEditor: our own editor, rendered in a fork of InAppWebView\n\nData and cache: GraphQL, REST over Dio, Isar, ObjectBox\n\nNative: Swift, Kotlin, WidgetKit and SwiftUI, Jetpack Glance, WorkManager, Firebase Cloud Messaging\n\nSecure storage: iOS Keychain, Android Keystore\n\nBuild and design system: GitHub Actions, Fastlane, internal Flutter component library\n\nServices you will call: public REST and GraphQL APIs\n\nObservability: Sentry, PostHog\n\nEveryday tools: GitHub, Plane (yes, we run on it), Figma, Slack\n\nWhy Plane?\nEvery company says it is different. We will try evidence instead.\nThe scope is real. We are a passion team serving companies of every size, including some of the largest in the world. Something you ship this month will run inside a Fortune 500 company and a 50-person startup in the same week, and you will hear from both.\nThe constraints make you better. Plane runs in our cloud, in customers' clouds, and on machines that will never touch the internet. Much of the work happens in the open, where the issues, the fixes, and the roadmap conversations are public. Building software that survives all of that is harder than building an ordinary SaaS product, and it is a better education than most companies can offer.\nThe people-and-agents future is being built here, in production. We think humans and AI agents will share one system of action for work. We are building that system now, for customers who already depend on it, and you will work on that problem directly whatever your role.\nYour name is on the work. The teams are deeply connected enough that credit and responsibility both find you fast. That is some pressure. Mostly it is the fun part.\nIf that sounds like your kind of place, we would like to meet you.\nPlane is an equal opportunity employer. We do not discriminate based on race, color, religion, gender identity or expression, sexual orientation, national origin, age, disability, veteran status, or any other protected characteristic under applicable law.","description_format":"text","description_chars":8424,"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":["Project & Work Management Software","Intranet & Knowledge Management"],"lifecycle":[{"event":"open","at":"2026-10-09T04:06:55Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.438,"p_room":0.45,"age_days":53,"expected_fill_days":27,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/planesoftware-software-engineer-mobile-flutter","json_url":"https://alion.io/job/planesoftware-software-engineer-mobile-flutter.json","meta":{"generated_at":"2026-10-11T21:04:28Z","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":9661,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"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":6934},"rest":"https://alion.io/mcp/rest/get_company?id=6934"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fplanesoftware-software-engineer-mobile-flutter"},{"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%2Fplanesoftware-software-engineer-mobile-flutter"},{"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%2Fplanesoftware-software-engineer-mobile-flutter"},{"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/planesoftware-software-engineer-mobile-flutter\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fplanesoftware-software-engineer-mobile-flutter"}]}
