Responsibilities:

  • Lead and mentor a small team of 2–4 engineers, ensuring effective collaboration and high-quality delivery.
  • Define system architecture and stack management.
  • Oversee full development lifecycle.
  • Ensure quality, security, and scalability of delivered systems.
  • Collaborate with stakeholders to align delivery with requirements.
  • Manage risks and dependencies; escalate issues proactively.
  • Provide transparency of the development process and project status to stakeholders.
  • Evaluation & Roadmapping: work with product managers on product evaluating and roadmap planning

Requirements:

  • 1+ years of experience as a Senior/Lead Software Engineer, including mentoring or leading small engineering teams (2–4 developers).
  • Strong understanding of system architecture, SDK development, and API design.
  • Proficiency in TypeScript and modern frontend frameworks (React, Next.js)
  • Experience integrating with Web3 libraries (e.g. TonConnect, ethers.js, @solana/web3.js) and building Web3 applications.
  • Solid knowledge of DeFi protocols (DEXes, lending, staking, vesting, cross-chain solutions).
  • Hands-on backend experience (Node.js or similar) and familiarity with scalable system design is a plus.
  • English at B2 level or higher (written and spoken).

Nice-to-have

  • Backend development experience in Rust or Go or Python
  • Database expertise: SQL (e.g. PostgreSQL) and NoSQL (e.g. MongoDB)
  • Knowledge of integration tools, message queues (RabbitMQ / Kafka)
  • Experience with containerization and orchestration (Docker, Kubernetes clusters)
  • Experience with Web3 development on TON Blockchain

Why it is a fantastic opportunity:

  • The opportunity to work at the bleeding edge of blockchain tech
  • Ownership of core team delivery and influence over product direction
  • Fast-paced, flat-structured environment where your input matters
  • Remote-friendly culture with a collaborative and motivated team
