Senior Software Engineer (Full Stack)
Sonar, New York City
The role
Engineering at Sonar sits at the intersection of AI, finance, and infrastructure. You’ll be designing systems that power AI-driven fund diligence and portfolio management for institutional investors. You’ll work across the stack, from distributed systems and scalable data ingestion pipelines to AI agents and reporting interfaces that LPs rely on daily.
This role is ideal for someone who’s looking to jump into an early-stage environment (i.e. you’ll be figuring out a ton of things with us), enjoys thinking from first principles, and wants to build durable systems that reimagine how capital allocators evaluate and invest.
What you will do
- Build core systems from the ground up. Design and implement the foundations of Sonar’s product—from scalable APIs and distributed data pipelines to intuitive interfaces that bring complex information to life.
- Work across the stack. You’ll move between backend services, frontend components, and infrastructure, shipping features end-to-end.
- Apply AI pragmatically. Develop, evaluate, and productionize LLM-based features that make complex analysis simpler and faster for real users.
