Who are we?

We believe Ethereum has the potential to solve some of humanity’s most crucial coordination issues. Since our initial inception as a research group, we have sought to scale both its technology and values.

At present, the most pressing bottleneck to the growth of Ethereum is its performance and scalability. We are building the most elegant solution to this problem. We do this in the open (under an MIT open source license) because we believe in open source innovation and its ability to accelerate growth.

OP Labs contributes to the Optimism protocol, an extension to Ethereum that scales both its technology and values. Optimism enables orders of magnitude of improved performance and scalability to Ethereum while doubling down on its commitment to public goods.

The Optimism Collective leads the blockchain protocol landscape, dedicated to fostering a scalable and sustainable ecosystem. Optimism’s ethos, in sync with Ethereum's vision, tackles pivotal coordination challenges of the digital age. Optimism’s goal is to harmonize private incentives with public good, shaping a resilient future for the Internet. Optimism’s scope spans diverse areas like Gaming, DeFi, NFTs, and Enterprise.

If you're passionate about building in the open, thrive on tinkering with new technologies, have full stack experience and love being an active voice in the developer community, we'd love to hear from you!

What are the role responsibilities?

Your north star is to serve app developers building on the Superchain via several workflows:

• Build and maintain Developer tooling: Actively contribute to the improvement of our developer tools like supersim and super-cli.

• Build and Maintain public API/Services: Build tools like relayers, faucets, and specialized APIs that enable developers to build seamless superchain UX.

• Community engagement: Interact with the developer community to gather feedback and share it internally to help drive product enhancements.

• Internal collaboration: Work closely with engineering, product, and marketing teams across the organization to align on product specs and requirements and ensure our tools target the right use cases and personas.

• Open source contributions: Prefer open source efforts, working in the open to improve the superchain developer experience.

What skills do you bring?

• Strong background in full stack software engineering with experience building full stack application and APIs (experience building developer tools and/or blockchain applications is nice to have, as is some understanding of JSON-RPC and the EVM).

• Our code is largely written in Typescript, Solidity, and Golang. You should be comfortable writing in these languages or confident that you can pick them up quickly.

About the Team:

Zark Lab is building foundation models for blockchain transactions and information. Our work focuses on search, retrieval, and generative modeling applied to on-chain and off-chain data. We are developing systems that enable efficient indexing, retrieval-augmented generation (RAG), and vector search for structured and unstructured blockchain datasets. Our models process billions of transactions and smart contracts across multiple blockchains, applying sequence modeling, graph-based learning, and language models to extract insights and improve data accessibility.

The team consists of former founders, senior engineers, and executives from Google, Meta, Goldman Sachs, and other leading technology and financial institutions. Our backgrounds span large-scale distributed systems, machine learning, engineering, and information retrieval, and we are focused on advancing the state of AI-driven search and computation for blockchains.

What you will do:

• Build large-scale web scraping and ingestion pipelines for on-chain and off-chain blockchain data
• Develop and optimize search architectures, integrating vector search, ANN retrieval, and ranking models
• Fine-tune LLMs for query expansion, semantic search, and retrieval-augmented generation (RAG)
• Reduce query latency through index optimization, ANN search, and distributed execution
• Scale distributed indexing pipelines for efficient storage, deduplication, and retrieval
• Optimize distributed storage and compute with Snowflake, ClickHouse, RocksDB, and vector databases
• Build scalable systems to process high-throughput blockchain transactions and queries
• Deploy and optimize cloud workloads on GCP with Kubernetes and containerized processing

You might thrive in this role if you:

• BS/MS/PhD in Computer Science or a related field.
• 5+ years of experience in AI/ML, distributed search, or large-scale data processing.
• Strong programming skills in Python, TypeScript, or Node.js.
• Expertise in database design (SQL and NoSQL) and high-throughput data systems.
• Experience with web crawling, data scraping, and large-scale ingestion pipelines.
• Knowledge of vector search, retrieval-augmented generation (RAG), and embedding models (preferred).
• Hands-on experience with GCP, Kubernetes, and Docker for cloud-scale deployment.
• Passion for blockchain, AI search, and distributed systems.

Why join us?

• Work on cutting-edge generative AI and search technologies applied to blockchain
• Solve complex challenges in large-scale indexing, vector search, and AI-powered retrieval
• Be part of a high-caliber team of former founders, engineers, and executives from leading tech and financial firms
• Competitive salary and equity opportunities
• Fully remote team with a fast-moving, high-impact culture
• Own and shape the future of AI-driven search and retrieval for Web3

If you’re excited about search, generative AI, and real-time blockchain inference, we’d love to hear from you.
