Known for its lean and high-impact development culture, ChartHouse Labs empowers developers to work autonomously on meaningful problems in decentralized technology.

They are currently seeking a TypeScript Developer to take ownership of the Wallet Connector Frontend and Core SDK for an advanced Account Abstracted (AA) Wallet. This role involves building secure, event-driven, and stateful infrastructure that enhances wallet UX and connects smart contracts to real-world applications.

Key Responsibilities:

• Manage SDK interactions and connector state reliably.

• Follow a defined interface spec to support downstream developers.

Wallet SDK:

• Design and build a robust TypeScript SDK.

• Integrate with scripts and smart contracts tailored for AA wallets.

• Convert UTXO transactions into AA-compatible formats.

• Handle cryptographic signatures and transaction responses effectively.

Key Requirements:

• Deep expertise in TypeScript – strong typing, generics, modular design.

• Skilled in Web Components frameworks and frontend architectures.

• Understanding of Browser Wallets and secure UI/UX principles.

• Solid grasp of UTXO models, inputs/outputs, transaction structure.

• Experience with Account Abstraction, signing abstracted transactions.

• Familiarity with standards like EIP-712 and EIP-191.

• A strong security mindset focused on delivering safe user experiences.

• Ability to reverse-engineer systems, debug across stack layers, and build in low-documentation environments.

Nice to Have:

• Experience testing wallet/connector interfaces using Playwright, Puppeteer, or Cypress.

• Knowledge of blockchain gas fee estimation and optimization.

• Contributions to open-source SDKs or blockchain development libraries.

Ideal Candidate Traits:

• Self-driven, seasoned developer with a background in Web3, JavaScript/TypeScript, and smart contracts.

• Curious, adaptable, and aligned with decentralization principles.

• Comfortable exploring new blockchain frameworks and debugging unfamiliar codebases.
