Back-End Developer (Node.js, TypeScript, MongoDB) for Scalability in a Crypto Trading Platform

We are Gainium, a fast-growing platform specializing in automated crypto trading. We’re looking for an experienced Back-End Developer with expertise in Node.js, TypeScript, and MongoDB to help us scale our platform to handle a high volume of users and trading bots efficiently.

Our current challenge is scaling the platform to support 1M+ trading bots while optimizing performance and minimizing costs. You’ll work closely with our team to design and implement solutions for high-concurrency systems and ensure our backend architecture is robust and future-proof.

Key Responsibilities:
• Design and implement scalable backend solutions using Node.js and TypeScript.
• Optimize MongoDB and Redis for high-volume data processing and real-time performance.
• Collaborate on API design to handle millions of concurrent processes.
• Work with cloud infrastructure and containerized environments for seamless deployment.
• Diagnose and resolve bottlenecks in existing systems, improving performance.

Qualifications:
• 3+ years of experience with Node.js and TypeScript in production environments.
• Proven expertise in scaling applications, including optimizing databases like MongoDB and caching layers with Redis.
• Experience building high-concurrency systems or distributed architectures.
• Familiarity with cloud platforms (AWS, GCP, or Azure) and containerization tools (Docker, Kubernetes).
• Strong problem-solving skills and ability to diagnose complex issues in real-time.
• Knowledge of security best practices for APIs and data handling.

Preferred Skills:
• Experience with real-time systems or trading platforms (crypto or otherwise).
• Familiarity with message brokers (e.g., RabbitMQ, Kafka) for asynchronous processing.
• Contributions to open-source projects or demonstrable personal projects.

Why Work With Us?
• Gainium is a community-focused platform that empowers traders with cutting-edge tools.
• You’ll be working on a challenging, high-impact project with a talented team.
• Opportunity to shape the architecture of a rapidly growing platform.

Project Scope:
This is a long-term position starting with a trial phase. You’ll start with addressing specific scalability issues and move into a more integral role in the platform’s development.

How to Apply:
Please share:
1. Your relevant experience with Node.js, TypeScript, MongoDB, and Redis.
2. Examples of systems you’ve scaled successfully.
3. A brief description of how you would approach handling 1M+ bots in a high-concurrency environment.

=== IMPORTANT ===
Do not apply using AI, it's very easy to tell who's using it and your application will come across as not genuine. I am interested in what you have to say even if it's not perfect, not in what the AI has to say.

We look forward to hearing from you!
