STON.fi is seeking a Technical Product Manager to own the vision, strategy, and execution for Omniston, our decentralized liquidity aggregation protocol built for the TON blockchain. Omniston connects liquidity providers and DeFi applications through a single, scalable, and future-proof protocol — unlocking unmatched distribution, faster integrations, and new revenue streams.
In this role, you'll lead Omniston’s development and growth as a critical infrastructure layer for TON DeFi, working closely with engineering, design, and business teams. You’ll need both technical fluency and product leadership skills to drive partner adoption, roadmap execution, and continuous improvement of the protocol.
What You’ll Do
Own the development and execution of the Omniston roadmap — from protocol core logic to integrations and external tooling
Define and maintain protocol-level specifications, RFCs, and interface schemas for matcher engines, offer makers, relayers, and UI clients.
Translate abstract liquidity and execution models into clear, testable product specifications
Define and manage technical integrations (e.g., gRPC, WebSockets, smart contracts, referral systems)
Review and contribute to smart contract designs, offchain execution workflows, auction models, and transaction delegation mechanisms
Specify and manage low-level APIs (WebSocket, REST, gRPC), real-time data feeds, offchain signature flows, and permission models
Identify architecture bottlenecks and contribute to the design of scalable and fault-tolerant offchain systems
Gather insights from ecosystem partners (wallets, DEXs, OTC desks) to shape product direction
Lead cross-functional teams across technical development, business development, and marketing
Align product development with broader STON.fi strategy and DeFi market trends
Support design and improvement of execution reliability, timeouts, retries, and fallback paths for mission-critical flows
What We’re Looking For
5+ years as a software engineer, systems architect prior to (or alongside) product roles.
Experienced in at least one language (Python, Go, C++, Rust, Java), able to read and debug production-grade code and propose fixes
Experience building distributed systems: understanding of availability, eventual consistency, retries, queueing, and timeouts
Hands-on experience defining, shipping, and iterating on complex technical products (protocols, APIs, relayer infrastructure)
Ability to manage technical complexity and break it down into incremental, testable, and trackable product phases
Clear communication skills, written and spoken, to bridge across engineers, integrators, and business stakeholders
Comfortable working with external partners (developers, projects, liquidity providers)
Strategic mindset with strong execution skills
Fluency in both Russian and English (spoken and written)
Why Join Us
STON.fi is one of the leading projects in the TON ecosystem, building critical DeFi infrastructure at scale. You’ll get full ownership of a complex, strategic product — and help build the infrastructure that will power next-generation DeFi applications.
