As a Senior Flutter Developer on the DTC Calling team you'll build and evolve the flagship BOSS Revolution app.\n\nYour main direction is Product-Led Growth (PLG): the referral program (Refer-a-Friend), onboarding and activation funnels, promo and reward mechanics (loyalty and subscription offers, first-transfer and recharge bonuses, upsell offers), and the experiments that decide which of them ship. It is the main direction, not the only one: you'll take on any work the team owns — home, calling, money-transfer and top-up flows, subscriptions and payments — as the roadmap requires.\n\nYou'll work in one of the largest Flutter codebases in production — a monorepo of 100+ internal packages, feature-first clean architecture, and a strong engineering culture around code quality, testing, and automation — and ship in short, instrumented iterations: hypothesis → flag → variant → metric → decision. The app also carries a native calling stack (SIP/VoIP on Android and iOS); experience there is welcome, not required.\n\nGrowth (main direction)\n\nBuild growth mechanics end-to-end: referral flows (invite links, deferred deep links, reward tracking), onboarding & activation funnels, promo/reward dialogs and offer surfaces, in-app surveys — from a PRD with a success metric to a measured result in production.\n\nRun experiments as a habit: ship behind feature flags, wire variant assignment from our remote-config / A/B service (fixed-split and multi-armed-bandit tests) and Firebase Remote Config, tag events with test and variant, watch guardrail metrics, and remove the flag once the test is decided.\n\nInstrument and validate analytics: define and implement Amplitude/GA events and properties, keep the event taxonomy clean across releases, verify events before launch, and read funnel dashboards together with the PM and data team.\n\nRender server-driven promo content: integrate with our in-house campaign platform — targeted campaigns, remotely configurable copy and creatives, layout updates pushed from the backend in real time — with versioned fallbacks, so campaigns launch without an app release.\n\nIntegrate third-party growth SDKs: attribution (AppsFlyer), Braze (push, content cards), ads (AdMob / AppLovin), payments and KYC vendors — mostly through Flutter plugins, occasionally extending them in Kotlin/Swift via platform channels.\n\nAcross the app and team\n\nShip product features beyond growth: home screen, calling flows (Flutter UI over the native SIP stack), money-transfer and top-up flows, subscriptions and payments (card and wallet flows, Google/Apple Pay), country selection, chat and social features, performance and tech-debt work — the same standards, a different surface.\n\nOwn features within our architecture: feature-first clean architecture, Bloc/Cubit state management, repositories, immutable state, Result-based error handling; migrate legacy Provider/ViewModel code in the modules you touch (e.g. the referral module) to the current patterns.\n\nWork at real scale: a Melos-managed monorepo with 100+ packages, strict dependency hierarchy, code generation (jsonserializable / freezed), a shared design system, and a 90% diff-coverage gate enforced per package in CI (bloctest + mocktail).\n\nKeep releases healthy: trunk-based development, ~2 releases a month through GitHub Actions and Fastlane, Crashlytics plus product-metric monitoring, staged rollouts and kill-switches for risky changes.\n\nCollaborate cross-functionally: with product managers (growth and core product), backend engineers (campaign, config and A/B services), data & BI, marketing (Braze campaigns) and QA — and push back on asks that cannot be measured.\n\nUse AI-assisted development as part of the everyday workflow: Cursor / Claude Code / Copilot with in-repo prompts, agents and MCP integrations.\n\nWymagania\nRequirements\n\n5+ years building mobile apps, including 3+ years with Flutter in production.\n\nStrong Flutter/Dart: Bloc/Cubit or comparable structured state management, async programming and isolates, code generation, dependency injection, clean architecture and modularization.\n\nHands-on, experiment-driven product development: feature flags and remote config (Firebase Remote Config, LaunchDarkly, Statsig, GrowthBook or an in-house service), A/B rollout mechanics (staged rollout, sticky assignment, kill-switch) and analytics instrumentation (Amplitude, Mixpanel, GA or similar) — including knowing how your experiments ended.\n\nDeep linking, including deferred deep links and App Links / Universal Links setup; understanding of attribution flows.\n\nWorking knowledge of native Android (Kotlin) and/or iOS (Swift) at the level of platform-channel and SDK integrations.\n\nStrong testing culture: unit and bloc tests with mocked collaborators, deterministic tests, comfortable working under coverage gates.\n\nFull lifecycle experience: Git, CI/CD (e.g. GitHub Actions), code signing, store deployment, post-release monitoring.\n\nProduct mindset: can work from a PRD with success metrics, propose instrumentation and guardrails, and explain trade-offs to non-engineers.\n\nEnglish: Upper-Intermediate or higher.\n\nNice to have\n\nTime on a dedicated growth or monetization team: referral programs, onboarding optimization, paywalls / subscriptions, retention work, multi-armed bandits.\n\nAttribution and marketing SDKs by name: AppsFlyer, Kochava, Adjust, Branch; Braze, Iterable, CleverTap.\n\nServer-driven UI or remotely configurable content systems.\n\nPayments and subscriptions on mobile: card flows, 3DS, in-app purchases, Google/Apple Pay.\n\nVoIP / real-time communication: SIP, WebRTC, CallKit / Telecom framework, push-triggered call handling, audio session management.\n\nLarge monorepos (melos, Mason, Dart workspaces); migrating legacy state-management patterns.\n\nBeyond mobile: backend / BFF for growth features, data pipelines, observability.\n\nTelecom, fintech or other regulated consumer products (KYC, fraud vendors).\n\nComfort with AI-assisted development tooling.\n\nOferujemy\nWhat we offer\n\nRemote b2b (Georgia-Moldova) or on-site employment (Belarus-Moldova) work opportunity!\n\nStable job with long-term growth perspective.\n\nCompetitive salary with annual performance review.\n\nReally good hardware.\n\nAn exciting and challenging job with talented people around.\n\nContinuous learning and career growth opportunities.\n\nCompensation for professional training, seminars, and conferences.\n\nReferral program – get rewarded for helping us grow the team with talented people.\n\nCompany-supported English classes to enhance your professional growth.\n\nMore perks for the Minsk and Chisinau office employees.","description_format":"text","description_chars":6785,"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":["Continuous learning","Growth opportunities"],"hiring_locations":[{"name":"Belarus","iso":"BY","kind":"country"},{"name":"Georgia","iso":"GE","kind":"country"},{"name":"Moldova","iso":"MD","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Unified Communications"],"lifecycle":[{"event":"open","at":"2026-10-19T19:48:15Z"},{"event":"close","at":"2026-10-21T19:51:45Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/idt-senior-flutter-software-engineer-2","json_url":"https://alion.io/job/idt-senior-flutter-software-engineer-2.json","meta":{"generated_at":"2026-10-23T04:44:23Z","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":7723,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":2253004},"rest":"https://alion.io/mcp/rest/get_company?id=2253004"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fidt-senior-flutter-software-engineer-2"},{"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%2Fidt-senior-flutter-software-engineer-2"},{"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%2Fidt-senior-flutter-software-engineer-2"},{"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/idt-senior-flutter-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fidt-senior-flutter-software-engineer-2"}]}
