[Hiring] Web3 Frontend Developer @Bitso

Role Description

onchain.cc is Bitso's onchain trading terminal: 50,000+ traders, over $10M in daily volume, and roughly 300% growth since we turned it into a terminal in April 2026. Perps and prediction markets carry most of the revenue, and all of it happens on the client surface. That surface is the product, and it is the one you would own.

• Own the client surface of the onchain.cc terminal end to end: trenches, perps, and prediction markets, across Solana and EVM.
• Take sole ownership of at least one revenue-bearing surface, from proposal to production, including its execution and fill-quality UX.
• Take the trenches terminal to parity or beyond against pump.fun, Axiom, and FOMO on the interactions that decide a fill: latency, snipe controls, live data, and one-click execution.
• Unify Solana and EVM wallet and transaction flows into a single surface, holding the Capacitor mobile app at feature parity.
• Propose what to build. Product judgment on latency-critical trading UX is the part of this job that does not get delegated.
• Drive down front-end latency on the trading surfaces, measured as p95 time to interactive and time to fill.
• Own the production defect rate and incident recurrence on the surfaces you ship.

Qualifications

• Shipped onchain product to production. Real products carrying users and real money: perps, DEXs, launchpads, prediction markets, or trading terminals.
• Experience with Solana and EVM, both, with no friction.
• Traded trenches yourself and understand a fill, slippage, priority fees, and why an entry gets lost.
• Demonstrable ownership: proposed features, built them, and shipped them without a spec, a ticket, or permission to move.
• Experience with latency and real-time in the browser: websockets, RPC streams, optimistic UI, reconnection, and backpressure.
• Familiarity with trading UI depth: charting (TradingView), order flow, PnL, fills, transaction states, and handling onchain failures.
• Experience with wallet UX: Solana adapters, embedded wallets (Privy or similar), signing and approval flows.
• Genuinely AI-native in your daily work, with a clear account of what you delegate to an agent and how you review what comes back.
• Comfortable in high-performance remote work, with reasonable overlap with a global team.

Requirements

• Individual contributor role with no direct reports.
• Work alongside one other frontend engineer and a UX engineer, with backend and DevOps in the same eight-person unit.
• Reports directly to the Head of onchain.cc.

Benefits

• Me Time program, including unlimited paid time off.
• Remote-first work environment.
• Employee Stock Option program.
• Zero trading fees through our Bitso app.
• Extended Family Leave policy: all birthing parents, non-birthing parents, and adopting parents are eligible for a 4-month leave.
• Premium health, dental, and life insurances in Mexico, Brazil, and Argentina.
• Volunteering days.
