Role overview
Bitso is seeking a Frontend Developer for its onchain trading terminal, onchain.cc, to own the client surface end to end across Solana and EVM — covering trenches, perps, and prediction markets. The role is for a trader who actively participates in the trenches (pump.fun, Axiom, FOMO, etc.) and wants to build the product they already use, shipping features autonomously with no spec or permission layer in a small, intense, AI-native team.
Responsibilities
- 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
Requirements
- Shipped onchain product to production — real products carrying users and real money: perps, DEXs, launchpads, prediction markets or trading terminals (e.g., Hyperliquid, Polymarket, pump.fun, Axiom or equivalent). Side projects do not count
- Solana and EVM both, with no friction — not "I know EVM and I will learn Solana" and not the reverse. You have shipped on both
- You trade trenches yourself — you understand a fill, slippage, priority fees, and why an entry gets lost. We want a user of the product, not an observer of the category
- Demonstrable ownership: you have proposed features, built them and shipped them without a spec, a ticket or permission to move
- Latency and realtime in the browser — websockets, RPC streams, optimistic UI, reconnection and backpressure. You can explain a performance problem by its cause, not by reciting a recipe
- Trading UI depth — charting (TradingView), order flow, PnL, fills, transaction states, and handling onchain failures in a way a trader can act on
- 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
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-months leave
- Premium health, dental and life insurances in Mexico, Brazil and Argentina
- Volunteering days
Additional details
- onchain.cc is Bitso's onchain trading terminal: 50,000+ traders, over $10M in daily volume, and roughly 300% growth since it was turned into a terminal in April 2026
- Perps and prediction markets carry most of the revenue, and all of it happens on the client surface
- Reports to the Head of onchain.cc
- Individual contributor role with no direct reports
- The team is eight people, five in engineering, with no intermediate layer
- You work alongside one other frontend engineer and a UX engineer, with backend and DevOps in the same eight-person unit
- We are AI-native across the whole workflow, not as decoration, and deep into post-agile practices
- We compete for onchain distribution against terminals that move fast, and have watched a few go past us in the rearview already
- With over 8 million users, Bitso is the leading cryptocurrency platform in Latin America, developing the cryptocurrency ecosystem in the region and enabling financial inclusion
- Bitso cultural values and traits tested when hiring: Mission-Driven (passionate about crypto and resilient facing industry challenges), High Sense of Urgency, Exceptional Hard Skills (no room for mediocrity), Self-Management (independently manage work, career, and professional development)
- Diversity note: Research suggests individuals may hesitate to apply if they don't meet all listed criteria; at Bitso, unique strengths could be exactly what is looked for, so if the role excites you but you don't match every point, they still want to hear from you
- This role is expected to work remotely
