About Boundless

Boundless is a protocol for accessing verifiable compute on any chain and rewarding nodes for contributing useful work. Our mainnet launch in September 2025 pioneered Proof of Verifiable Work (PoVW), a novel mechanism for verifiably rewarding provers for generating ZK proofs, and raised $71M from its community sale (18× oversubscribed). Through The Signal campaign, we raised ~300 ETH to prove the finality of every Ethereum block using ZKasper, the first ZKVM-friendly implementation of Casper FFG. We've built a network of 2,500+ provers generating billions of proofs daily. With breakthrough products like Kailua (the leading ZK fraud-proof system reducing rollup finality from days to hours) and Zeth (the first Type 0 zkEVM), we're making zero-knowledge proofs practical and accessible across Web3. Our technology powers critical infrastructure including EigenLayer’s slashing system, BOB’s hybrid ZK rollup, and Citrea’s Bitcoin zkRollup.

We’re looking for a strong middle-plus Blockchain Integrations Engineer to join us at the ground level. You’ll play a key role in designing and implementing integrations between rollups, bridges, and ZK systems across our ecosystem. You’ll be working on these projects and more :

  • Kailua
  • Steel
  • Blobstream0

We have a long list of upcoming integrations in the pipeline as well. We welcome international applicants, Boundless is built by a global team, and we love working across time zones and cultures.

What You'll Do

  • Develop state-of-the-art integration solutions for rollups and bridges using zero-knowledge technology.
  • Work closely with other Boundless engineers to expand and enhance existing integrations.
  • Implement and maintain smart contracts and off-chain components that connect different blockchain systems.
  • Participate in code reviews, architecture discussions, and open-source contributions.

    • Tech Stack

  • Smart Contracts : Solidity.
  • Backend / Infra : Rust.
  • Zero-Knowledge : RISC Zero / Boundless Market.

    • Requirements

    • Nice to Have

  • Experience writing Go.
  • Familiarity with non-EVM chains.
  • Previous work on early-stage startups or solo product builds.
  • Interest in building clean, minimal UI / UX experiences.
