Software Engineer - Solana
Propr is an onchain prop trading firm that funds traders with its own capital to trade crypto, equity, commodity and forex perpetuals as well as prediction markets. Traders who pass a funded challenge keep 80% of profits, with instant USDC payouts and transparent, publicly trackable execution. Propr serves individual traders as well as AI agents and algorithmic trading systems via a public API, and also offers a funding layer that other trading apps can integrate.

About Propr
Propr describes itself as the onchain prop trading firm, funding traders with its own capital to trade 150+ markets, including Hyperliquid perpetuals (crypto, equities, commodities, forex) and Polymarket prediction markets. Traders pay a one-time fee to complete a challenge by hitting a profit target within daily loss and drawdown limits, then get verified via a one-time KYC to become funded and keep 80% of profits, with instant on-demand USDC payouts settled onchain and publicly trackable with transaction hashes. The platform emphasizes radical transparency, publishing real-time trading, payout and revenue data, and is built to be agent-friendly, offering a REST API and Python/JS SDKs so AI agents and algorithmic traders can access funded capital in minutes. Propr also positions itself as a funding layer that other trading apps can integrate, giving their users native funded challenge accounts, particularly for products already built on Hyperliquid and Polymarket. It does not serve traders in the US, UK, Russia, or OFAC-sanctioned regions.
Skills
About the Role
You will design and build Solana programs using Rust and the Anchor framework, integrating with major Solana DeFi protocols such as Jupiter, Drift, Meteora, and Raydium. You'll implement real-time WebSocket feeds for Solana accounts, transactions, and program logs, and build automated trading strategies that execute on Solana with sub-100ms latency. You'll develop on-chain risk management systems including position limits, liquidation triggers, and PDA-based account validation. You'll write comprehensive integration tests against devnet and mainnet RPC nodes, optimize transaction construction for compute unit limits, priority fees, and account pre-fetching, and design secure PDA schemas and CPI patterns.
Requirements
- 3+ years of software engineering experience, 1+ years building on Solana
- Production experience writing Solana programs in Rust with Anchor framework
- Deep understanding of Solana architecture: accounts, PDAs, CPIs, compute units, rent
