Smart Contract Engineer

About HODL 

HODL Markets tokenizes sophisticated investment strategies and provides distribution access to a wide audience. The company has been operating since the beginning of 2025 with a successful launch of a DeFi app MVP.  

In July 2026, HODL undertook a significant company pivot, which involves the relaunch of our flagship product, previously known as HODL Protocol. The new, V2 product, will be more focused on enabling simpler integrations with distribution partners using AI-agent-friendly documentation. It will also integrate a much-improved workflow for our partnered managers, automating the strategy licensing and trading process. 

Our objective is simple: democratize accessibility to gated investment products and asset classes. The first step of this mission is by bringing tokenized hedge fund strategies to a widespread audience.  

Company Milestones 

Before the end of this year: We’re aiming to complete a strategic fundraising round, in partnership with major Fintechs who will be our first, and exclusive (for some hedge fund strategies) distribution partners. 

• By the end of this year: We’re aiming to relaunch our platform and serve our first institutional customers through one or more strategic distribution partners. 

• By early next year: We’re aiming to expand our offering to Canada and Switzerland. 

• By this time next year: We’re aiming to partner with most of the U.S.’ major registered investment advisors, so they can seamlessly direct their client portfolios into hedge fund strategies when appropriate. 

The Role – Smart Contract Engineer 

HODL is seeking a Smart Contract Engineer to design, build, and maintain the smart contracts that power its tokenized vault platform.

• Implement on-chain accounting.  

• Develop access-control and compliance mechanisms.  

• Maintain contract security lifecycle.  

• Collaborate with third-party security audits.

• Experience in at least one backend language (Python, Rust, Go) for off-chain services.   

• Disciplined approach to testing, documentation, and code review.
