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.

• Strong foundation in blockchain architecture and interoperability concepts.

• Production experience with Solidity and/or Rust.
• Understanding of cross-chain communication, rollup mechanics, or bridge protocols.
• Ability to work independently and deliver robust integrations from scratch.
• Clear communication skills and collaborative mindset.

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.
• Strong product vision and systems thinking.

At Boundless, we take care of our people, because building the future of decentralized computing starts with an empowered team. Here’s what you can expect when you join us:

• Competitive Salary.
• Annual Offsites.
• Bi-Weekly Virtual Coffees.
• Home Office Budget.
• 401(k) Plan (USA Only).
• Healthcare, Dental & Vision.
• Professional Development.
• Fully Remote Work.
• An Exceptional Team.
