Senior Product Designer

Tonkeeper

Design · Senior

We’re building Tonkeeper, the leading non-custodial wallet in the TON ecosystem, helping users and developers discover dApps and DeFi tools. Tonkeeper Team has also created TON API, the largest platform on TON, and Tonviewer, a top explorer for tracking transactions, tokens and NFTs. With Tonkeeper Mobile, Tonkeeper Pro, TON API and Tonviewer, we make it easy to explore and grow on The Open Network

Our team has plenty of experience in building products for mass adoption, and high-load services, as well as in applying innovative technologies in cryptography and blockchain.

This role focuses on end-to-end design for Tonkeeper — native iOS and Android apps and the trading experience inside them.

This is a mature product with millions of users: the cost of a mistake is high, and the room for simplification is huge. You'll work in close partnership with engineering and product, turning complex blockchain mechanics into interfaces people use every day.

This role is for a self-directed designer who sets their own agenda, defends decisions with data and intuition, and doesn't need micromanagement.

Responsibilities:

• Design end-to-end product experiences for Tonkeeper's native iOS and Android apps.
• Evolve the trading UX — swaps, buy/sell, staking — for precision, speed, and trust.
• Turn complex flows (keys, seed phrases, TON Connect, transaction signing) into simple, secure interfaces.
• Rapidly explore, prototype, and iterate.
• Use product analytics, qualitative research, and judgment to guide decisions.
• Maintain and grow the design system and product quality standards.

Requirements:

• 3+ years of experience working on mature products (1M+ MAU as a reference point).
• Shipped meaningful features in native mobile apps (iOS and/or Android).
• Strong product thinking — you see the logic, metrics, and edge states behind a mockup.
• Comfortable in ambiguity and fast at getting things to release.
• Strong communication skills and experience collaborating cross-functionally with product and engineering teams.
• A portfolio that shows both thinking and execution.

Preferred skills and experience:

• Background in crypto, fintech, or trading interfaces.
• Understanding of self-custody specifics — security as part of the UX, not a blocker.
• Fluency with modern design and prototyping tools.
• Familiarity with exchange / trading interface patterns (orders, charts, execution states).

Why it is a fantastic opportunity:

• Our business is growing at an exponential scale.
• Non-bureaucratic management that focuses on results.
• Regular performance reviews to assess your progress.
• Remote setup with access to our hubs in Dubai, Yerevan, London and Belgrade.
• Compensation for medical expenses.
• Provision of necessary equipment.
• Employees get access to the most advanced AI models via mira.tg.
• 20 working days of paid vacation annually.
• 11 days off per year.
• 14 days of paid sick leave to support your health and recovery when needed.
• Access to internal conferences, English courses and corporate events.
