Job description

As a Senior Software Engineer - Backend (AI Agent Platform), you will play a key role in designing, developing, and deploying the backend systems that power our AI agent platform. You will work on challenging problems related to distributed systems, scalability, real-time processing, and the integration of AI/ML models into production. You will work closely with data scientists, machine learning engineers, frontend engineers, and other stakeholders to build a robust and innovative platform. You will be a hands-on developer, writing high-quality code and contributing to architectural decisions.

Key Responsibilities:

• Design, develop, and maintain scalable, reliable, and performant backend services for the AI agent platform.
• Implement APIs and microservices for interacting with AI models, data pipelines, and other platform components.
• Write high-quality, well-tested, and maintainable code (primarily in Go, potentially with some Java or Python).

AI/ML Integration:

• Work closely with data scientists and machine learning engineers to deploy and integrate AI/ML models into the platform.
• Develop and maintain infrastructure for model serving, monitoring, and retraining.
• Optimize model performance and scalability in a production environment.
• Experience with deploying LLM and SLM models.

Real-time Processing:

• Design and implement systems for real-time data processing and event handling.
• Work with technologies like WebSockets, message queues (Kafka, RabbitMQ), and streaming platforms.
• Collaborate with data engineers to integrate the AI agent platform with data pipelines for training and inference.
• Work with various data storage technologies (SQL, NoSQL, data warehouses).

Scalability and Performance:

• Design and implement systems that can handle high volumes of data and traffic.
• Identify and address performance bottlenecks.
• Optimize system performance for speed, scalability, and cost-effectiveness.

Security: Implement secure coding practices and work closely with the security team to ensure the security of the platform.

• Work effectively in a cross-functional team, collaborating with product managers,
• designers, frontend engineers, data scientists, and other stakeholders.
• Communicate technical concepts clearly and concisely.
• Provide technical guidance and mentorship to junior engineers.
• Participate in code reviews and contribute to improving engineering best practices.
