WE wilke experience

PROJECT: We are building 4connection – a modern messenger with interest-based communities, serious dating/matching features, strong encryption, accessibility and youth protection. The iOS client is built natively in Swift. SwiftUI for the interface, Firebase for push and real-time features, Keychain for secure storage. Like the Android developer, you work with the backend developer from day one – features are tested against real APIs, not against mocks.

REQUIREMENTS: 1+ years of experience in native iOS development with Swift. Understanding of the iOS app lifecycle and background processing. Experience with Firebase (Cloud Messaging, Firestore). Basic knowledge of secure storage (Keychain). Experience with Git and project management tools (Redmine). Good English skills (reading and writing).

NICE TO HAVE: Experience with SwiftUI. Experience with accessibility features (VoiceOver, Dynamic Type, accessible navigation). Knowledge of youth protection or age verification concepts. Experience with APNs (Apple Push Notification service). Experience with real-time chat or messaging apps.

RESPONSIBILITIES: Implementing the complete iOS client based on UI/UX mockups. Building the chat interface, group features and matching/dating UI. Integrating Firebase for push notifications and real-time data. Implementing accessibility features for full VoiceOver and Dynamic Type support. Collaborating with the backend developer on API integration and testing. Owning the entire iOS client – every line of code is your responsibility.

WE OFFER: Fully remote work. A small, focused team without overhead. Direct communication, short paths, real input on architecture decisions. AI-assisted development with Claude. The iOS client will be released as open source – your code will be seen by the community. Fair compensation, long-term collaboration. Open-source tooling throughout.

Tech Stack: Swift, SwiftUI, Firebase, Apple Keychain, WebSocket, Git, Redmine, Nextcloud

PROJECT: We are a software and design studio working on Linux and open source, with a globally distributed team, concentrated in Ukraine and spread around the world. You administer our systems and keep them running: Nextcloud, our Docker-based services, Gogs, Redmine, Strapi, our website hosting and the usual Linux infrastructure. You automate routine tasks and document your work so the team can rely on it.

REQUIREMENTS: Solid experience administering Linux servers (Debian or Ubuntu). Confident on the command line and with shell scripting. Practical Docker and Docker Compose experience. Nextcloud administration. Experience with Git (Gogs or similar). Networking basics (TCP/IP, DNS, firewalls, reverse proxy). You document what you do, clearly and reliably. You actively use AI tools in your daily work (we use Claude) for scripting, troubleshooting and documentation. Good English (reading and writing).

NICE TO HAVE: Web hosting and CMS administration (Strapi or similar). Redmine administration. Nginx as reverse proxy and TLS certificate handling. WireGuard or other VPN setups. Backup strategies and restore testing. Basic monitoring and CI.

RESPONSIBILITIES: Operating and maintaining our systems (Nextcloud, Gogs, Redmine, Strapi, website hosting, Docker-based services). Handling updates and patches. Setting up and testing backups. Light monitoring. Documenting the infrastructure so it stays maintainable for the whole team.

WE OFFER: Fully remote work, flexible hours. A small, focused team with no corporate overhead. Open source by default, Linux only. AI-assisted work as a fixed part of the workflow. Long-term collaboration.

Tech Stack: Linux, Docker, Docker Compose, Nextcloud, Gogs, Redmine, Strapi, Nginx

Required language: English B1 (Intermediate)

PROJECT: We are building 4connection – a modern messenger with interest-based communities, serious dating/matching features, strong encryption, accessibility and youth protection. The Android client is built natively in Kotlin – no Flutter, no React Native. You will implement the UI from professional mockups, build the chat experience, integrate matching features and ensure the app is accessible and compliant with youth protection standards. The app connects to a Rust backend and uses Firebase for push notifications and real-time features.

REQUIREMENTS: 1+ years of experience in native Android development with Kotlin. Understanding of the Android lifecycle (Activities, Services, Background Processing). Experience with Firebase (Cloud Messaging, Realtime Database or Firestore). Basic knowledge of secure local storage (Android Keystore, EncryptedSharedPreferences). Experience with Git and project management tools (Redmine). Good English skills (reading and writing).

NICE TO HAVE: Experience with Jetpack Compose. Experience with accessibility features (TalkBack, content descriptions, scalable UI). Knowledge of youth protection or age verification concepts. Experience with real-time chat or messaging apps. Experience with matching/recommendation UIs.

RESPONSIBILITIES: Implementing the complete Android client based on UI/UX mockups. Building the chat interface, group features and matching/dating UI. Integrating Firebase for push notifications and real-time data. Implementing accessibility features to ensure the app is usable for everyone. Collaborating with the backend developer on API integration and testing. Owning the entire Android client – you know every corner of your codebase.

WE OFFER: Fully remote work. A small core team of 4 developers with direct communication. No Scrum theater, no daily standups – real collaboration instead. AI-assisted development with Claude. The Android client will be released as open source – your code will be publicly visible. This is both responsibility and opportunity. Fair compensation, long-term collaboration. Open-source tooling throughout (Nextcloud, Redmine, Git).
