Technical Product Manager - Remote

Overview

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 Short

• 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.

Requirements

• 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.

Benefits

• Full ownership of a complex, strategic product.
• Opportunity to help build the infrastructure that will power next-generation DeFi applications.
• Work with a leading project in the TON ecosystem.
