Design and build core systems for a chartered trust company: ship React/TypeScript UIs, create agent-driven workflows for compliance and document generation, integrate with custodians/banks, and architect backend systems that ensure data integrity and correctness.
We are building a new modern trust company.
What you will do
Who we are looking for
The team
Trusts hold trillions of dollars and are one of the main ways wealth moves between generations. A trust company acts as a trustee for trusts, essentially a legal bridge between generations by holding assets and executing the specific wishes of a family. Sava is building a new full-stack, chartered trust company. Not just software for banks and lawyers, but the actual regulated entity.
We have raised a $10M seed round from Y Combinator, Gradient Ventures, Max Mullen (Instacart founder), SV Angel and other great investors.
You will design and build the core systems of the company.
You will:
- Build and ship product surfaces that make complex financial and legal structures understandable
- Develop high-quality interfaces using React and TypeScript
- Build agent-driven workflows for compliance, document generation, and asset movement
- Integrate with custodians, banks, and legacy financial systems
- And much more.
You will be one of the first engineers. The architecture you build will shape the company for years.
You are someone who likes hard problems that matter.
You probably:
- Have been a founder, early engineer, or technical lead at a strong startup
- Care deeply about systems, data integrity, and correctness
- Are comfortable owning big pieces of a product with little structure
- Understand modern AI tooling and how to use it for both software development and real automation
- Have good product and UI taste and can be trusted to make clear, competent interface decisions
You do not need prior finance experience.
You will work in person in NYC with the founders:
- Nimit Maru, 2x YC founder, previously started and sold two companies to public companies, most recently Fullstack Academy
- Rush Sadiwala, experienced serial founder with deep financial and operational experience
We are building a small, high-caliber team. The first engineers define the technical culture of a company. This role is that.
If you want to build something foundational, difficult, and important, you should talk to us.
