Senior Full Stack AI Engineer

About the Role

We are looking for a skilled Senior Software Engineer with a strong background in Generative AI, Agentic AI, and applied software engineering. You will play a key role in building agentic AI systems, designing prompt-driven workflows, integrating tools with LLMs, and mentoring the team on the latest advancements in AI technologies.

Roles and Responsibilities

• Architect and build AI-powered tools using LLMs (OpenAI, Claude, Mistral, etc.) with best practices in prompt engineering and context engineering.
• Integrate and customize AI agents using frameworks like Lang Chain, Google ADK, Claude Agent SDK, or custom solutions.
• Utilize observability and evaluation tools such as Langfuse.
• Collaborate with product and research teams to translate requirements into prompt workflows and agent behaviors.
• Design and implement scalable systems and infrastructure to support AI agents and workflows, using suitable tools and technologies.

Prompt Engineering & Agentic Workflows

• Design advanced, multi-agent workflows that incorporate memory, dynamic context injection, and multi-step reasoning.
• Experiment with and optimize agentic architectures for real-world tasks (retrieval, generation, summarization, etc.).

Front-End Integration

• Collaborate with UI/UX or front-end teams to integrate AI-powered features into user-facing applications as needed.

Adaptability & Learning Mindset

• Willingness and ability to quickly learn and adapt to new technologies, frameworks, and tools as needed. Open to working across the stack to support the development of AI-powered solutions. Comfortable stepping beyond core skill sets to contribute wherever needed in the AI application lifecycle.

Testing & Dev Ops

• Write unit and integration tests to ensure reliability.
• Participate in code reviews, CI/CD pipelines, and deploy models/services using best practices.

Mentorship & Collaboration

• Upskill peers in GenAI, prompt engineering, and best practices.
• Contribute to knowledge-sharing and architectural reviews across teams.
• Stay updated with evolving AI ecosystems, tools, and research.

Requirements Technical Proficiency

• Strong programming fundamentals (OOP, security, performance).
• Experience building scalable and modular systems using modern frameworks and tools.
• Proficiency with LLMs, OpenAI/Anthropic APIs, Lang Chain or similar.

Full Stack Development

• 6+ years of experience in full stack development.
• Strong experience with:
• API design and service-oriented architectures
• Backend development in one or more modern languages (Python, Java, PHP, Type Script or similar)
• Distributed systems and cloud-based infrastructure
• SQL and relational databases
• Proven ability to design systems with performance, reliability, and scalability in mind.

GenAI & Agentic AI

• 1+ years of experience working with GenAI and LLMs.
• 1+ years of experience in prompt engineering and AI agent architectures.
• Familiarity with agent frameworks like Lang Chain, Google ADK, and Claude Agent SDK.
• Experience with Agentic IDEs such as Cline, Cursor, and Replit.
• Strong understanding of the Cursor Rule (intent → context → action), a principle for structuring agent behavior, and real-world experience applying it in workflows.
• Solid understanding of how to construct and pass dynamic context to LLMs, including techniques like session memory and prompt templating.
• Experience adapting or customizing LLMs is a plus.

Additional Technical Exposure (Good to Have)

• Familiarity with vector databases and graph databases is a plus.

Soft Skills

• Excellent communication and collaboration skills.
• Self-driven and eager to mentor and share knowledge.
