Job description

Job Title: Senior Core Platform Developer

Location: New York City

Team: Technology – Engineering & Infrastructure

Reports to: Head of Core Platform and Analytics

About Jain Global: Jain Global is an innovative multi-strategy / multi-manager investment firm founded on the basis of achieving scale on Day 1 across regions, markets and investors. With over 400 employees operating from offices in New York, Houston, London, Singapore, and Hong Kong, we are looking to add to our growing teams.

Role Overview

We are seeking a Senior Core Developer who combines deep technical expertise with strong product intuition and stakeholder alignment. This role is central to the design and evolution of the firm’s internal core platform, enabling the delivery of high-impact, scalable software solutions across front, middle, and back‑office teams. The ideal candidate will be a product‑oriented engineer—comfortable working closely with business users to understand their workflows and pain points, and delivering tooling, frameworks, and services that directly improve the speed and quality of internal application development. This is a high‑ownership, cross‑functional role within a global, fast‑moving environment.

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.

Preferred Experience

• Experience working with non‑technical stakeholders (e.g., operations, risk, compliance, finance) to co‑design workflows and applications.
• Exposure to low‑code/no‑code platforms or internal developer portals.
• Prior experience in building application platforms or shared component libraries in fast‑growing organizations.
• Knowledge of operational or risk‑related workflows in a hedge fund, financial institution or similarly regulated/high‑performance industries.

Why Join Jain Global?

• Shape the foundation of the firm’s technology platform at a fast‑growing investment firm with global scale and startup dynamism.
• Work with modern technologies in a high‑impact environment where platform engineering is a strategic priority.
• Collaborate with world‑class talent across disciplines—from trading to data science to infrastructure.
• Competitive compensation and benefits, with strong emphasis on growth, innovation, and ownership.
