This is a full-stack engineering role within a high-performance quantitative trading firm, where precision, security, and craftsmanship matter. The team designs and builds internal platforms that integrate with best-in-class third-party systems (UKG, ADP, payroll, compliance, and others) while also developing custom solutions that cannot be purchased off the shelf. The group operates a dedicated on-premises hardware environment to support systems responsible for highly sensitive firm data. As a Senior Developer, you will work end-to-end - from architecture and application design to deployment and operational support - in collaboration with experienced engineers and cross-functional stakeholders. What You'll Do * Build solutions leveraging LLMs running on our on-prem GPU infrastructure * Design and build secure, scalable applications supporting critical business functions * Architect and maintain integrations across enterprise systems (HR, payroll, compliance, compensation) * Build internal tools and platforms where commercial solutions do not meet business needs * Work across the full SDLC: architecture ? development ? deployment ? monitoring * Contribute to a dedicated on-premises infrastructure environment * Collaborate with engineers, analysts, and system owners to translate complex requirements into production-ready systems End-to-End Ownership Engineers contribute across application, integration, and infrastructure layers. Security-Focused Engineering Systems support highly sensitive data (e.g., compensation, performance, firm-wide workflows) and are designed with strict isolation and reliability standards. Complex Systems Environment Multiple integrations, diverse data flows, and enterprise-scale workflows require thoughtful system design and strong engineering fundamentals. Firm-Wide Impact The platforms built by this team directly support critical operational functions across Susquehanna. ## Related Videos - [API Design - Getting Started](https://www.wearedevelopers.com/videos/33-api-design-getting-started) - [Fault Tolerance and Consistency at Scale: Harnessing the Power of Distributed SQL Databases](https://www.wearedevelopers.com/videos/1146-fault-tolerance-and-consistency-at-scale-harnessing-the-power-of-distributed-sql-databases) - [Python-Based Data Streaming Pipelines Within Minutes](https://www.wearedevelopers.com/videos/1233-python-based-data-streaming-pipelines-within-minutes) - [HR & Tech: Why can't we be friends?](https://www.wearedevelopers.com/videos/1493-hr-tech-why-can-t-we-be-friends) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [The Software Engineer 2030: From Coder To AI Orchestrator? - Patrick Schnell](https://www.wearedevelopers.com/videos/1825-the-software-engineer-2030-from-coder-to-ai-orchestrator-patrick-schnell) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [6 Reasons to Use Java For Your Next AI Project](https://www.wearedevelopers.com/magazine/111-6-reasons-to-use-java-for-your-next-ai-project) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
