Blockchain Integrations Engineer

About Boundless

Boundless is the universal ZK protocol making blockchains internet-scale. It turns zero-knowledge proofs into a tradable resource: a global marketplace where anyone can contribute compute and power applications, rollups, and infrastructure across every ecosystem. Boundless introduced Proof of Verifiable Work (PoVW), a new incentive model that rewards nodes for generating proofs that strengthen the network. As more provers join, capacity grows and computation becomes abundant rather than scarce, transforming how blockchains scale and interact. Since launch, Boundless has become the world’s largest proof network, uniting hundreds of provers, processing more than 500 trillion cycles of compute, and producing the first consensus proof of Ethereum.

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.
