About Aqua

Aqua is the operating system for wealth channel alternatives. We are building the platform for independent broker-dealers (IBDs) and independent financial advisors (RIAs) to invest in alternative assets. We are on track to process $5B in new transactions for 2025, with customer logos including some of the largest RIAs/BDs in the nation and asset managers including Blackstone, Apollo, JLL, Blue Owl, etc. 

About the Role

We're hiring a talented and dynamic founding engineer to help us reimagine how alternative investments are managed. The alternative investment industry is notoriously manual and operationally complex—we're building technology to change that.

You'll be responsible for:

  • Developing our core product that streamlines complex investment workflows for clients
  • Building intelligent automation systems
  • Creating the technical foundation that enables institutional-quality service delivery at scale
  • Owning end-to-end projects from conception to deployment, working directly with the CTO
  • Shaping our technical architecture and engineering culture as a founding team member

This is a rare opportunity to define how a modern alternative investment platform should work, building both client-facing products and the operational infrastructure that makes scalable service possible.

Who You Are

  • 3-5+ years building scalable applications, ideally at fast-growing startups
  • Product-minded—you stay connected to users and business context, using technology to solve real pain points
  • Thrive in high-autonomy, ambiguous environments and move fast
  • Measure success by organizational impact, not lines of code
  • Write robust, high-quality code and design scalable, reliable systems
  • Comfortable working across the stack when needed
  • Experienced with cloud infrastructure and distributed systems architecture
  • Communicate effectively with both technical and non-technical stakeholders
  • Familiar with AI-driven applications and agentic workflows
  • Willing to roll up your sleeves and do whatever it takes to solve problems

Bonus Points:

  • Experience architecting and building AI applications or agents
  • Strong UI/UX intuition and have built polished interfaces

Our Stack

  • Frontend: Angular, React
  • Backend: Python, Express (Node.js)
  • Infrastructure: AWS, Terraform
  • Database: PostgreSQL, MySQL
Technology
