Were building a next-generation prediction-market protocol that redefines how people trade on outcomes. Users can buy outcome tokens, trade against self-bootstrapping liquidity, and rely on modular oracles all through a mobile-first, localized experience designed to onboard the next billion traders.
Were looking for a smart contract engineer who cares deeply about precision, security, and elegant design. Someone who optimizes away repetitive work, enjoys tearing apart complex mechanisms to rebuild them better, and has a healthy respect for the fact that on-chain code is immutableand users are trusting you with real money.
As a Senior Smart Contract Developer, you will own the design, implementation, and evolution of the protocols on-chain systems. Your day-to-day will involve:
Designing and developing secure, gas-efficient smart contracts for core protocol components.
Building outcome-token mechanics, automated liquidity logic, oracle integrations, and settlement flows.
Conducting rigorous internal audits, fuzzing, property-based testing, and testnet simulations.
Working with backend and product teams to ensure seamless off-chain on-chain interactions.
Monitoring production contracts, identifying risks, and deploying improvements with minimal disruption.
Contributing to protocol architecture decisions, future roadmap planning, and economic mechanism design.
Writing documentation that makes the system understandable for auditors, integrators, and your future self.
4+ years of software engineering experience, with 2+ years focused on Solidity or other EVM-based smart contract development.
Deep understanding of EVM internals, gas optimization, state management patterns, and security best practices.
Hands-on experience with Hardhat, Foundry, or similar testing and development frameworks.
Strong background in designing upgradeable systems, proxy patterns, or immutable architecture.
Familiarity with oracle frameworks, AMMs, prediction markets, or other complex on-chain mechanisms.
Proficiency in at least one backend language (TypeScript, Python, or Go) for integration and simulation work.
Strong grasp of economic incentives, adversarial thinking, and attack-surface reduction.
Experience building or auditing smart contracts in trading, DeFi, or derivatives protocols.
Knowledge of L2 ecosystems, account abstraction, signature schemes, or cross-chain messaging.
Prior contributions to open-source protocol codebases.
Familiarity with formal verification, fuzzing frameworks, or invariant testing.
We operate as a tight, flat team. You should be someone who:
Treats security, correctness, and clarity as non-negotiable.
Is comfortable challenging assumptions and defending technical decisions.
Communicates clearly with engineers, product managers, and non-technical stakeholders.
Stays resourceful when solving unfamiliar or novel problems.
Thinks several steps ahead and spots design risks early.
Ownership and autonomy over key protocol components.
A collaborative culture that values pragmatism, rigor, and innovation.
The opportunity to shape one of the most ambitious prediction-market protocols in the space.
Real influence on protocol design, roadmap direction, and long-term architecture.
