Senior Executive Assistant to General Partner - Investment Firm

Compensation: $125K - $150K

Location: New York City, USA (Fully Office-Based Required)

We are a premier global investment firm focused on the future of decentralized technology and blockchain ecosystems. Since 2018, we have partnered with over 150 visionary startups, combining deep technical expertise with a hands-on approach to help founders scale transformative projects. As a highly institutionalized fund, we manage relationships with some of the world’s most sophisticated investors, including sovereign wealth funds and global endowments.

We are seeking a senior, high-trust Executive Assistant to work directly with our Founder. This is not a traditional administrative role; it is a high-leverage position designed for a strategic thinker who can operate in ambiguity and act as a true extension of the Founder. You will be responsible for filtering noise, synthesizing complex information, and ensuring that strategic priorities are executed with precision.

As we transition our global operations to a new flagship office in New York City, this role will be central to maintaining the Founder's momentum and organizational clarity.

We are looking for a highly capable Smart Contract Engineer (Rust) to join our core engineering team and shape the technical backbone of our protocol.

Senior Frontend Engineer - High-Performance Financial Platform

Location: New York, San Francisco (Office)

Compensation: $185K - $300K

We are hiring on behalf of our client who are building a revolutionary Multi-Asset Margin solution for one of the fastest-growing ecosystems in decentralized finance.

Their platform allows users to post variable forms of collateral without needing to sell their assets for stablecoins. By building sophisticated blockchain-integrated systems "under the hood," they extend liquidity to the venues of their users' choice, bringing the market to them rather than forcing them to navigate multiple fragmented platforms.

As a member of their Product & Platform team, you will build and maintain the applications that power these services. You will collaborate closely with designers, backend engineers, and product managers to deliver responsive, high-performance user interfaces that define the future of DeFi trading.

The Frontend Engineer will be responsible for the full lifecycle of application development, focusing on performance, user experience, and real-time data visualization.
