About Us:

At Bytebricks, we are at the forefront of the AI revolution, building intelligent, large-scale systems that redefine what's possible. We don't just use technology; we architect the future of it. We are seeking a brilliant and highly skilled LLM Engineer who is passionate about building the complex backend systems required to power cutting-edge generative AI applications. If you are driven to solve intricate problems and build robust, scalable AI solutions from the ground up, we want to hear from you.

What You'll Do:

As an LLM Engineer, you will be the architect behind our most innovative AI features, responsible for the entire lifecycle of our generative AI solutions, from model integration to the underlying infrastructure.

• Architect Advanced AI Systems: Design, develop, and deploy sophisticated LLM-powered applications, including complex multi-agent workflows using frameworks like LangGraph, CrewAI, and OpenAI Swarms.
• Build and Optimize RAG Pipelines: Engineer and fine-tune state-of-the-art Retrieval-Augmented Generation (RAG) systems. You will work with vector databases like Pinecone to create highly contextual and multi-modal AI experiences.
• Deploy and Fine-Tune Language Models: Manage the deployment and continuous optimization of various LLMs (including models from OpenAI, Claude, Groq, and open-source alternatives) on hosted Linux virtual machines, ensuring low latency and high throughput.
• Engineer Core Backend Infrastructure: Build the robust, scalable backend that our AI depends on. This includes designing and implementing secure REST APIs using Python (FastAPI, Django), managing authentication (JWTs, sessions), and ensuring system reliability.
• Optimize Data and Performance: Manage and optimize relational databases (PostgreSQL, MySQL) and leverage in-memory caching with Redis to ensure our AI systems are highly responsive and performant under load.
• Develop Real-Time Voice AI: Construct high-performance, low-latency pipelines for Text-to-Speech (TTS) and Speech-to-Text (STT) to enable seamless real-time conversational AI.

What We're Looking For:

Core AI/LLM Expertise:

• Deep, hands-on experience designing and building applications with LLM orchestration frameworks like LangChain and LangGraph.
• Proven expertise in architecting and optimizing RAG systems and deep familiarity with vector databases (e.g., Pinecone).
• Demonstrable experience with multi-agent systems (Agents SDK, etc.) and the principles of collaborative AI.
• Practical experience fine-tuning and deploying LLMs on custom infrastructure, with a strong focus on performance and scalability.
• A solid understanding of multi-modality in AI systems.

Essential Backend Engineering Foundation:

• Advanced proficiency in Python and modern backend frameworks, particularly FastAPI (Django/Flask experience is a plus).
• Strong command of relational databases (PostgreSQL, MySQL) and extensive experience with Redis for high-performance caching.
• Solid experience building, securing, and scaling RESTful APIs and a deep understanding of authentication patterns (e.g., JWTs).

Soft Skills:

• A collaborative mindset with a proven ability to work effectively in a distributed team.
• Exceptional problem-solving skills, with a focus on creating scalable, high-performance solutions.
• A relentless passion for learning and staying at the frontier of artificial intelligence.

Why Join Us?

• Pioneering Projects: Work on genuinely innovative projects that leverage the absolute latest in AI and backend technology.
• Deep Technical Challenges: Solve complex, meaningful problems that will push your skills to the limit.
• Flexibility & Autonomy: Enjoy the freedom of remote work and the autonomy to architect solutions your way.
• Growth & Development: Be part of a culture that invests in continuous learning and professional growth.
• Competitive Compensation: We offer a top-tier salary and benefits package that recognizes and rewards your expertise.
