Join us as a Senior Frontend Engineer to drive cutting-edge solutions while growing in a collaborative, forward-thinking environment. 

The Project

We are building a financial platform that will research and run systematic trading strategies.  We collaborate with the quant team on strategies research, risk modeling, and portfolio optimizations. Our software engineering team embeds the corresponding logic into the platform.  Similar systems already exist on the market, but quants need to use several of them to research and run trading strategies. Our client’s idea is to build a system that can do it all.  

Client: Several quants with 15+ years of Wall Street experience.  

Team: 15+ people divided into independent sub-teams. These are Backend Software Engineers, Frontend Software Engineers, SRE engineers, Team Leads, Project Manager, QA Lead, and SDET​.

Project’s Stack:

Frontend: Material UI, React, Jest.

Backend (Microservices): Kotlin, Groovy, Micronaut, Spock, Python, Dagster, Flask, Locust, FastAPI, Pytest, Pandas, NumPy, SQLAIchemy.

Databases: PostgreSQL.

Infrastructure/pipelines: AWS, Terraform, Terraspace, Docker, GitHub Actions.
