Member of Technical Staff C++

Job Title : Backend Engineer (AI-First | FinTech/Crypto)

Experience : 3 to 6 Years

Location : Gurugram (Sector 49)

Working Hours : 10:00 AM – 6:00 PM

Work Mode : On-site | 6 Days Working

Employment Type : Full-time

Role Overview :

This is not a typical ticket-based engineering role. You will take end-to-end ownership of systems—designing architecture, building scalable solutions, and solving real-world performance challenges.

We operate in an AI-first engineering environment, leveraging advanced tools and automation workflows to build high-performance distributed systems.

Mandatory Skills :

Java/Spring Boot or Node.js, System Design (HLD/LLD), Distributed Systems, Event-Driven Architecture (Kafka/RabbitMQ), Low-Latency APIs, PostgreSQL/MongoDB, CI/CD, Docker/Kubernetes, AI-assisted development (Copilot/Cursor/Claude)

Key Responsibilities :

• Design and build scalable backend systems (Java/Spring Boot, Node.js, or similar).
• Architect and implement event-driven systems (Kafka, RabbitMQ, pub/sub).
• Develop secure and reliable financial systems with strong data integrity.
• Solve scalability and performance challenges in fintech/crypto environments.
• Own features end-to-end: design → development → deployment → monitoring.
• Work with real-time data pipelines (WebSockets, streaming, event sourcing).
• Define service contracts and optimize system architecture.

AI-First Engineering (Must-Have Mindset) :

You will :

• Use tools like GitHub Copilot, Cursor, and Claude in daily development
• Follow spec-driven development using structured instructions
• Review, validate, and ship AI-generated code with strong engineering judgment

Core Requirements :

• 3+ years of backend development experience.
• Strong expertise in Java (Spring Boot) or Node.js.
• Solid understanding of System Design (HLD/LLD, Distributed Systems).
• Experience with event-driven architectures (Kafka, RabbitMQ, async pipelines).
• Hands-on experience building low-latency, high-throughput systems.
• Strong database knowledge (PostgreSQL, MongoDB, etc.).
• Understanding of security, performance optimization, and reliability.
• Experience with CI/CD, Git, Docker, Kubernetes.
• Exposure to React / React Native is a plus.

Good to Have (Differentiators) :

• Experience in FinTech / Crypto / Web3 / Blockchain.
• Built systems for trading, payments, or real-time financial data.
• Experience with AI agents, automation pipelines, or agent-based systems.
• Exposure to parallel AI workflows (coding / testing / refactoring).
• Contributions to open source or technical blogs.
• Experience handling production-scale systems.

• Proficient experience of minimum 3 years into C++ & experience using MFC library.
• Good experience into C# programming.
• Working experience into COM.
• Good Communication skills.

Key Responsibilities:

Backend Ownership

• Own the design, evolution, and reliability of mission-critical backend systems.
• Ensure scalability, performance, maintainability, and overall system health.
• Lead technical initiatives to address scaling challenges, technical debt, and architectural improvements.

System Design & Architecture

• Drive both High-Level Design (HLD) and Low-Level Design (LLD).
• Design scalable APIs, data models, service boundaries, and asynchronous workflows.
• Make sound engineering trade-offs balancing delivery speed with long-term system health.

Code Quality & Engineering Excellence

• Improve backend code quality through architecture reviews, code reviews, and refactoring.
• Simplify complex codebases and establish maintainable engineering patterns.
• Introduce best practices and guardrails to improve long-term maintainability.

Database & Performance Optimization

• Optimize PostgreSQL performance through schema design, indexing, query optimization, and tuning.
• Improve application performance using caching strategies and asynchronous processing.
• Design and operate analytics pipelines using ClickHouse or similar large-scale data systems.
• Work with messaging systems such as RabbitMQ or equivalent.

Technical Leadership

• Mentor backend engineers on architecture, debugging, and engineering best practices.
• Influence technical direction through thoughtful design discussions and strong technical reasoning.
• Raise overall engineering standards across teams.

Production Ownership

• Own production stability, incident management, and root cause analysis.
• Improve observability, monitoring, debugging, and operational excellence.
• Drive long-term reduction in production incidents and operational overhead.

Required Skills & Experience

Must Have

• 7+ years of backend engineering experience.
• Strong expertise in Node.js.
• Deep experience with PostgreSQL, including performance tuning and optimization.
• Experience designing and operating distributed backend systems.
• Strong understanding of system design, scalability, and microservices architecture.
• Experience owning backend services end-to-end—from architecture to production support.
• Strong debugging and problem-solving skills.
• Experience improving code quality, maintainability, and engineering standards.

Good to Have

• Experience with RabbitMQ or similar messaging systems.
• Experience with ClickHouse or large-scale analytics platforms.
• Experience deploying and managing applications on AWS.
• Strong knowledge of observability, monitoring, and production reliability.

What We're Looking For

Engineering Mindset

• Passion for improving existing systems rather than simply building new ones.
• Ability to simplify complex architectures and create maintainable solutions.
• Strong focus on writing clean, readable, and scalable code.
• Testing mindset with emphasis on reliability and long-term quality.
• Ability to evaluate technical trade-offs and design for future scalability.

Leadership Without Authority

• Influence technical decisions through expertise and clear reasoning.
• Challenge scope or timelines when necessary to protect system health.
• Mentor engineers and elevate overall engineering standards.
• Lead by example through hands-on technical excellence.
