We are seeking a Senior Backend Software Developer who is an expert in distributed systems and passionate about artificial intelligence . This role involves designing, developing, and maintaining backend microservices with high scalability and reliability. You will also explore ways to integrate AI / ML (e.g. large language models) into our products and development processes to enhance functionality and efficiency. As a senior engineer, you'll drive best practices in coding and architecture, and mentor others on the team.

Technologies we use  NodeJS, TypeScript, MongoDB, Redis, Elastic Search, AWS, Git, Docker, Kubernates, Distributed systems, Queueing systems

Key Responsibilities :

• Design and implement robust, scalable backend microservices and APIs in Node.js / TypeScript, following high coding standards and architectural best practices.
• Identify and implement opportunities to leverage AI within our platform or workflows – for example, using machine learning models or LLM APIs to improve features (such as fraud detection, personalization, or automation in our fintech products) or to streamline engineering tasks.
• Lead complex system design discussions, making architectural decisions that ensure our systems can handle high load, low latency, and high availability.
• Write high-quality, efficient code and unit / integration tests; debug and resolve issues across the software stack. Focus on code optimization, maintainability, and performance tuning.
• Perform peer code reviews and occasional pair programming, ensuring code quality and knowledge sharing within the team.
• Implement and maintain CI / CD pipelines and automated deployment workflows. Champion the use of testing frameworks and continuous integration to catch issues early and often.
• Produce clear technical design documents and contribute to product requirement discussions. Work closely with cross-functional stakeholders to translate requirements into scalable technical solutions.
• Collaborate with other engineers, data scientists, product managers, and operations to deliver end-to-end features. This includes potentially integrating AI models or analytics developed by data science into the production backend.
• Provide technical guidance and mentorship to junior engineers. Lead by example in adopting new technologies or practices (for instance, introducing a new AI toolkit or a performance optimization technique to the team).
• Ensure smooth delivery of code to production, including monitoring deployments and quickly fixing any post-release issues. Proactively monitor system health and respond to incidents, using automation or AI tools where possible to improve detection and response.
• Continuously improve our codebase and developer workflows. For example, you might propose a new internal tool, refactor a legacy service, or introduce an AI-powered code review assistant to increase team efficiency.
• Stay up-to-date with technology trends , especially in AI and backend development, and bring innovative ideas forward. Maintain a “get things done” attitude with a strong sense of ownership for the services you build.
