Job Overview

Role Summary

The Applications Development Technical Lead Analyst is a senior engineering and architectural leadership role based in India, operating as a key regional anchor within the global Position Management technology organization.

In this capacity, you will serve as the principal designer, systems architect, and hands-on lead engineer for mission-critical, low latency, and high-throughput platform. This platforms powers real-time controls, intraday position aggregation, P&L, commissions, anomaly detection, and live risk enforcement across global trading desks.

As an engineering leader, you will collaborate extensively with other global teams and stakeholders across Asia, Europe, and Americas. You will champion modern engineering practices - actively designing, building, and prototyping using AI-augmented tools such as GitHub Copilot, Devin to accelerate development of lifecycles, elevate code quality, and modernize enterprise architectures. Additionally, you will serve as the primary regional and global technical contact for Risk Managers, Product Owners, Front-Office Trading Desks, and cross-functional technology partners.

Key Responsibilities

• Architecture, System Design & Core Engineering (Hands-on)
• Architect & Design: Lead the end-to-end technical architecture and low-level design for distributed, fault-tolerant, high-concurrency risk calculation and position management engines supporting global trading sessions.
• Hands-on Development: 10+ years of experience toactively write, review, and optimize high-performance, multi-threaded production code primarily in C++, with targeted high-performance/low-latency modules in Java and exploring Rust where ultra-low latency memory safety and deterministic execution are required.
• AI-Augmented Engineering: Champion the adoption of modern AI development workflows (e.g., GitHub Copilot, Devin, AI-driven code review, and automated test generation) to enhance developer productivity, modernize legacy components, and accelerate time-to-market.
• Middleware & Event Streams: Design resilient, low-latency, event-driven pipelines using enterprise messaging backbones such as Apache Kafka, Solace PubSub+, and other low-latency middleware fabrics.
• Relational Databases: Proficiency in SQL writing queries and improve efficiency
• Performance Tuning: Profile, benchmark, and optimize CPU usage, memory layout, network serialization, and IPC for low latency.

Global Stakeholder Collaboration & Technical Advisory

• Key Technical Liaison: Act as a technical contact and subject matter expert (SME) for Risk Managers, Product Owners, Trading Desks, Quantitative Analysts, and Operations across APAC and global hubs.
• Global Team Alignment: Partner closely with regional and global engineering pods across Singapore, London, New York, and other tech centers to ensure seamless platform rollouts, operational stability, and cohesive architecture standards.
• Cross-Technology Coordination: Interface closely with upstream Order Management Systems (OMS), Execution Management Systems (EMS), Market Data feeds, and downstream Clearing/Settlement and Regulatory reporting platforms across multiple asset classes (FX, Equities, Rates, Commodities, Credit).
• Requirement Translation: Translate complex quantitative risk models, margin methodologies, and regional/global regulatory requirements into scalable, deterministic technical architecture

Mentorship & Regional/Global Leadership

• Lead, coach, and mentor junior engineers in regional teams in distributed systems design, clean code practices, and modern AI-assisted engineering techniques.
• Lead architectural design reviews and rigorous peer code reviews to ensure reliability, security, and maintainability across distributed codebases.
• Partner with engineering managers and Scrum Masters across time zones on sprint planning, technical estimations, dependency resolution, and milestone delivery.

Technical Proficiencies

• Java: Practical experience or working knowledge of Java for performance-critical, memory-safe, or low-latency system components and cross-language interoperability
• C++: Proficiency in modern C++, memory management/profiling, lock-free data structures, concurrent programming, and low-latency tuning in Linux platforms.
• SQL: Hands-on experience writing
