Job description

We’re hiring an experienced, pragmatic blockchain engineer to own core smart-contract development and backend integration work. You’ll build and test Solidity contracts (Foundry), implement secure MPC / BLS signing integrations, develop robust Python backend services that talk to exchanges and oracles, and help design production-grade token / stablecoin mechanics. You’ll be expected to ship high-quality, audited code and iterate quickly with product and security teams.

What you’ll do

  • Design, develop and maintain Solidity smart contracts (wallets, vaults, stablecoin logic, tokenomics).
  • Write thorough unit & integration tests using Foundry; fuzzing and property tests a plus.
  • Integrate smart contracts with Python backend services (attestations, session tokens, keeper / monitoring services).
  • Implement and integrate MPC / BLS signing flows with the backend and client SDKs.
  • Integrate with third-party APIs : price oracles, DEXs, CEXs, fiat on / off-ramps (REST / WebSockets).
  • Build secure mint / burn, collateral, liquidation, and fee systems for a stablecoin product.
  • Hardening, code review, working with auditors; help prepare audit packs and remediation.
  • Help run CI / CD, deployments, and maintain release processes for mainnet / testnets.
  • Mentor junior devs and drive engineering best practices.

Must-have

  • ≥5 years professional experience in blockchain development.
  • Strong Solidity skills and production experience writing & deploying EVM contracts.
  • Deep Foundry experience (writing tests, scripts, fuzzing).
  • Strong backend experience in Python (building API services, job / worker systems).
  • Experience integrating with CEX / DEX APIs and oracles.
  • Solid understanding of token mechanics, stablecoin design, and collateralized lending (LTV, liquidation).
  • Familiarity with MPC / TSS and / or BLS signing workflows (practical integration experience preferred).
  • Security-first mindset : experience with audits, threat modeling and secure development.
  • Excellent problem-solving, communication skills, and ability to work autonomously in a startup environment.

    • Nice-to-have

  • Experience with Account Abstraction / ERC-4337 and paymaster patterns.
  • Experience with OpenZeppelin, Clones (EIP-1167), UUPS / Beacon upgrade patterns.
  • Frontend exposure (JS / TS) or experience building SDKs or wallet integrations.
  • Experience with Chainlink or other oracle networks.
  • Familiarity with GitHub Actions / CI and Docker deployments.

    • What we offer

  • Meaningful equity for early hires (negotiable).
  • Up to ₹12 LPA depending on experience.
  • Opportunity to design and ship novel DeFi primitives used by everyday people.
  • Flexible / hybrid working arrangement, supportive team, and fast decision-making.
  • Hands-on role — influence product, security and go-to-market decisions from day one.

    • Interview process (typical)

    1. Quick screening call (20–30m) — background & motivation.

    2. Technical interview — Solidity & Foundry, system design (1–2 sessions).

    3. Live / Take-home challenge — small Foundry test + Python integration task.

    4. Final culture / compensation discussion.
