[Hiring] Flutter Developer @Yadda

Role Description

BlancVPN is looking for a Flutter Engineer | Senior to support the development of the client app as part of a team, alongside developers and owners of related domains (backend/infra)—from Flutter/Dart to native code for iOS/Android/Windows/Linux, platform channels (Pigeon), and integration with network kernels written in Go.

The goal of this role is to ensure a client that remains stable in a constantly changing environment — including during blockages, disconnections, channel degradation, and protocol detection — and an architecture that can withstand these challenges through engineering solutions.

Qualifications

• Fluency in Russian and English (B2+)
• 5+ years of experience in mobile development, with a significant portion spent working with Flutter and on complex production projects
• Native development for iOS and Android
• Thorough mastery of one platform: custom modules, platform channels, or Pigeon, and system APIs
• Proficiency in the other platform for confident coding and debugging
• Network layer below the HTTP client: TCP and UDP, TLS, sockets, routing, connection behavior during disconnections and degradation
• Low-level experience, even if minimal: C or C++, Go, Rust, dart:ffi, cgo, binary formats
• Ownership and design: end-to-end responsibility for a feature
• Debugging and investigation: ability to get to the root of a problem
• Testing: unit, widget, integration, and end-to-end tests

Requirements

• Domain expertise: VPN protocols (WireGuard, OpenVPN, Xray, Amnezia), bypassing blocks and DPI
• Low-level: binary protocols and custom implementations of protocols based on specifications
• Related Areas: server-side development, Go, Python, Linux nodes, Docker, basic DevOps
• Desktop: services and daemons, privilege escalation, installation of system components
• Development infrastructure: understanding how to set up an internal client infrastructure
• Public footprint: your own packages on pub.dev, open source, articles, low-level pet projects

Benefits

• Work from anywhere — fully remote (except Russia, Belarus, China, Syria, Iran, Yemen, North Korea, and some other regions)
• Flexible 5-day week — start when it suits you; loosely aligned to CET
• Full home-office setup — all the equipment you need, on us
• 40 flexible paid days off + paid sick leave
• Benefits — VHI, wellness, language courses, mental health support and a referral program
• Room to grow — annual development budget + in-person team meet-ups
