- Implement full-stack features using React.js, Next.js, and TypeScript on the frontend, with Python (FastAPI) and/or Node.js backends.
- Architect and oversee microservices, APIs, and service integration strategies.
- Own and evolve Cloud(AWS/Azure/GCP)-based infrastructure for web and backend workloads, using Terraform for infrastructure as code.
- Lead containerization and orchestration strategy using Docker and Kubernetes.
- Drive system reliability, security architecture, and cost optimization across services.
- Size and estimate projects across full-stack and AI workstreams; guide planning and prioritization.
- Operate within an Agile delivery model,



using Jira for planning and cross-team coordination.
- Mentor senior and mid-level engineers; champion high engineering standards through code and design reviews.

AI Engineering (Secondary)

- Set the technical direction for GenAI development, including model selection, pipeline architecture, and scalability strategy.
- Define and own best practices for LLM development, evaluation, and production deployment.
- Architect end-to-end LLM pipelines from experimentation to production, including RAG systems and retrieval infrastructure.
- Develop and standardize advanced prompt engineering frameworks across the team.
- Lead rigorous model evaluations and define performance optimization strategies.
- Design and oversee CI/CD pipelines tailored for AI systems.
- Architect and maintain AWS-based infrastructure for AI workloads (SageMaker, etc.).
- Build and evolve monitoring, observability, and evaluation tooling for LLM applications.

Candidate Requirements (Must Have)

- 10+ years of software engineering experience, including meaningful time in senior or lead roles.
- Deep full-stack development expertise using React.js, Next.js, and TypeScript.
- Strong proficiency in Python (FastAPI) and/or Node.js for backend services.




- Strong experience with Terraform and CI/CD pipelines (GitHub Actions or similar).
- Expert-level knowledge of Cloud Services (Eg. AWS Lambda, ECS, S3, etc.), Docker, and Kubernetes.
- Excellent background in system design, API architecture, distributed systems, and microservices.
- Experience driving engineering standards, cross-team alignment, and technical decision-making.
- Solid communication skills able to influence technical direction with peers and leadership.
- Proven track record of building and deploying LLM or GenAI applications
- Deep understanding of prompt engineering, LLM evaluation, and RAG systems.

Preferred

- Experience with fine-tuning, RLHF, or training LLMs.
- Familiarity with LangChain, LlamaIndex, or similar frameworks.
- Background in MLOps, model monitoring, and AI observability.
- Experience with A/B testing and experimentation frameworks.
- Open-source contributions or thought leadership in GenAI or distributed systems.
