Solutions Engineer, Japan

OP Labs builds Optimism, a blockchain network that powers the next generation of financial infrastructure. Hundreds of companies, from the world's largest enterprises like Sony, Coinbase, Kraken, Uniswap, OKX, and Bitpanda to the most ambitious early-stage builders, use the OP stack to launch their own blockchains and bring their users onchain. Today, over 65% of Layer 2 activity on Ethereum runs through the OP stack.

We are a small team building at the speed of the ecosystem we support. The NYC office is our center of gravity, and we have a strong preference for people who can join us there on a hybrid schedule. We've raised $178M from a16z, Paradigm, and others. We have our work cut out for us and are looking for exceptional people to join us.

Role and Responsibilities

We are looking for a Japan-based Sales Engineer to support Optimism’s enterprise and institutional adoption across the Japanese market. This role sits at the intersection of sales, product, and engineering, and is critical to helping large institutions evaluate, design, and deploy production-grade on-chain systems using the OP Stack.

You will partner closely with the Sales, Product and Engineering teams to leverage Optimism’s technology into institution-ready solutions; supporting technical diligence, performance testing, architecture design, and integration planning for Japan’s largest and most innovative enterprises. **This role must be based in Japan.**

What are the role responsibilities?

  • Translate enterprise requirements into clear technical feedback for OP Labs product and engineering teams

  • Help shape roadmap priorities related to institutional needs (e.g., performance, compliance tooling, privacy, sequencing models)

  • Support integrations with wallets, custody providers, cloud infrastructure, and system integrators (e.g., Fireblocks, AWS, SIs)

• Enable partners for production readiness

  • Guide partners through OP Stack architecture, deployment models, upgrade paths, and operational best practices

  • Support documentation localization and technical enablement in Japanese

  • Help customers compare and migrate from private / permissioned experimentation to public or hybrid production deployments

• Represent Optimism technically in Japan

  • Participate in technical workshops, partner meetings, and industry events alongside sales and Business Development

  • Serve as a trusted technical advisor to Japanese enterprises evaluating Layer 2 and blockchain infrastructure

  • Collaborate with local ecosystem partners (SIs, exchanges, wallets) to accelerate adoption
