Personal Assistant to Managing Partner
Kieran McLoughlin has navigated the highest levels of traditional finance as the former Head of the Central Bank of Ireland. Today, as Managing Partner at Astralis, he is at the frontier of Web3 investment. We are looking for a unique individual to bridge these two worlds: someone who understands the rigor of institutional finance but lives and breathes the decentralized future.
This isn't a traditional "admin" role. This is a high-bandwidth, high-stakes position for a Web3 native who can act as a technical filter, a marketing scout, and a strategic executor.
The Mission
Technical Intelligence: You are the "eyes" on-chain. You’ll be responsible for vetting protocols, testing dApps, and analyzing tokenomics. You should be able to break down a complex ZK-rollup or liquid staking architecture into a concise briefing.
Marketing & Alpha Hunting: You live on X (Twitter), Farcaster, and in closed Discord research groups. You identify emerging meta-narratives before they hit the mainstream. You understand why a community thrives and how a project builds its "moat" through marketing.
Strategic Operations: Managing the flow of a Managing Partner’s world. This includes coordinating with founders of top-tier Web3 projects, preparing materials for the Investment Committee, and ensuring Kieran’s digital and technical stack is always optimized.
Executive Presence: You will represent the office of the Managing Partner. You must be able to switch from degen-speak in a Telegram chat to professional discourse with institutional LPs.
The Profile (Who You Are)
On-Chain Native: You have a DeBank profile that tells a story. You’ve bridged, swapped, provided liquidity, and perhaps been "rugged" once or twice. You don’t just read about crypto; you use it daily.
Technical Literacy: You understand the difference between consensus layers and execution layers. You can read a smart contract (at least the basics) and understand the implications of governance proposals.
Marketing Intuition: You know what "good" looks like in Web3. You can distinguish between organic community growth and paid bot engagement.
Hyper-Organized: You are a master of calendars, task management, and information flow. You thrive in high-pressure environments where speed and accuracy are non-negotiable.
Discretion & Integrity: Working with an ex-regulator requires the highest level of ethics and confidentiality.
Why This Role?
Direct Mentorship: Work side-by-side with Kieran McLaughlin. This is a masterclass in macroeconomics, regulatory strategy, and venture capital.
Access: You will be in the room for the deals that will define the next cycle of Web3.
Impact: Your technical and marketing insights will directly inform the Investment Committee’s decisions.
How to Apply:
Standard CVs are fine, but we care more about your "proof of work." Along with your resume, send us:
A brief summary of your most interesting on-chain move or investment thesis.
