Job description

Key Responsibilities

• Design and build internal core platform services (e.g., authentication, user permissions, UI frameworks, data access layers) that power business‑critical applications.
• Partner with PMs, operations, risk, compliance, investment teams, and other enterprise‑scale business functions (e.g., marketing, or data platforms) to understand use cases, prioritize features, and deliver thoughtful, well‑scoped solutions.
• Own core components of the application stack including service orchestration, observability, error handling, deployment pipelines, and shared libraries.
• Define standards for application architecture, frontend/backend patterns, and platform onboarding for internal developer teams.
• Drive the delivery of reusable frameworks that reduce development time and promote consistency across teams.
• Collaborate with infrastructure, data, and security teams to ensure resilience, security, and scalability of platform components.
• Mentor engineers and champion best practices across product development, testing, and operational support.
• Design and integrate generative AI workflows, vector databases, and LLM‑powered services to accelerate internal application development.

Qualifications

• 6+ years of experience as a software or core platform engineer in complex, high‑performance environments (e.g., hedge funds, fintech, capital markets, enterprise SaaS, or large‑scale data/AI platforms).
• Proven success delivering internal tooling or shared platforms with a clear focus on user needs and business alignment.
• Strong software engineering skills in Python; experience with C++, Java, C#, or other compiled languages a plus.
• Familiar with multi‑threading concepts building high throughput, low latency systems; experience with backend frameworks (e.g., FastAPI, Node.js).
• Hands‑on experience with building cloud‑native apps, containerization (Docker), orchestration (Kubernetes), CI/CD (GitHub Actions, ArgoCD, Jenkins, Spinnaker, or equivalent tools), and cloud infrastructure (AWS preferred, GCP experience welcome).
• Experience integrating generative AI and LLMs into modern technical solutions (e.g., LLM orchestration, RAG, embeddings, vector databases).
• Familiarity with RBAC/ABAC, microservice architecture, and service mesh patterns.
• Excellent communication skills; ability to translate between technical and non‑technical audiences and drive cross‑functional initiatives.
