The primary responsibilities of the Portfolio Manager will be portfolio and risk management for Alternative Investment Funds (“AIFs”) and Separately Managed Accounts (“SMAs”, i.e. discretionary portfolio management mandates) dedicated to professional investors, with a particular focus on crypto-assets, tokenized assets and decentralised finance (“DeFi”).
You will also play a central role in building CS AM’s on-chain asset management capability, from strategy design and smart-contract-based execution to the risk monitoring of DeFi protocols and tokenized real-world assets. In this role, you will report to the Senior Portfolio Manager and CEO.

- Contributing to investor, audit and regulatory reporting and producing risk reports.
- Researching, back-testing and implementing new systematic strategies based on derivatives, crypto-assets, tokenized assets and DeFi protocols.

- Assessing DeFi protocols and tokenized assets before any investment (smart-contract, oracle, liquidity, counterparty and governance risks) and monitoring them on an ongoing basis.
- Building and maintaining production-grade tools (data pipelines, signal generation, portfolio construction, pre-trade and post-trade controls) together with the group development team.
- Participating in the expansion of the alternative and on-chain investment offering.
- Working closely with the risk, compliance, research, development and marketing teams of CS AM and the CoinShares Group.
