    Software Engineer, Full Stack (Frontend-Leaning)

    Location: New York City (SoHo) — In-Person

    About Our Client

    Our client is building the next-generation platform for institutional finance. The OTC derivatives market moves trillions of dollars daily on infrastructure that hasn’t meaningfully evolved in decades—this team is modernizing that foundation with a delightful user experience, a modern cloud-native stack, and an AI-native architecture designed for how financial services will operate over the next 10–20 years.

    The team comes from trading, quantitative, and engineering roles at top-tier financial institutions, and they’re building systems capable of processing complex, high-stakes transactions across global markets. Their customers include sophisticated banks, hedge funds, and asset managers—meaning the problems are hard, the expectations are high, and the impact is real.

    Tech Stack

    • Cloud-native architecture (serverless-first) + Infrastructure-as-Code (IaC)

    • Backend services in Python and Java

    • Frontend in TypeScript / React

    • AI tooling leveraging modern foundation models

    • Automated SDLC with tools like GitHub, Logfire, Vercel, and rapid intraday deployment practices

    • Partner with product and design to translate complex workflows into intuitive user journeys

    • Integrate with backend services (Python/Java) through REST and/or GraphQL APIs

    • Contribute to scalable architecture, clean code practices, testing, and deployment automation

    • Help enhance platform reliability and performance in a high-expectation, high-velocity environment

    • Experience with databases (e.g., MongoDB or other object/document databases)

    • Experience integrating with RESTful and/or GraphQL APIs

    • Familiarity with cloud infrastructure and deployment (AWS, GCP, or Azure)

    • Strong software design fundamentals across frontend and backend

    • Ability to collaborate cross-functionally (engineering, product, design)

    • Strong debugging, problem-solving, and communication skills

    Bonus Qualifications

    • Financial systems knowledge: reference data, pricing, market data integrations

    • Experience with trade capture, valuation, risk, or post-trade workflows

    • Familiarity with derivatives, FX, or fixed income products

    • Experience with reconciliation and operational data pipelines

    • Prior experience supporting institutional clients in capital markets

    • Experience building or integrating Generative AI (OpenAI, Anthropic, Gemini) into financial applications

    What Success Looks Like (First 90 Days)

    • Ship meaningful frontend improvements that reduce friction in core workflows

    • Build confidence with the domain (OTC derivatives + post-trade lifecycle) and the platform architecture

    • Improve UI performance, reliability, and developer velocity through clean patterns and automation

    • Become a trusted owner of key product surfaces used by sophisticated institutional customers
