Full-Stack Software Developer – AI Engineering

Rubenius Interior Wellbeing LLP | Bengaluru, India | On-site | Full time

About Rubenius

Rubenius Interior Wellbeing LLP is a design-and-build organization where spaces meet technology.

We work across commercial environments, experience centres, workplaces, retail, hospitality and experiential projects — bringing together design, software, AI, automation, IoT and interactive technology to build smarter, more engaging experiences.

We don’t just build spaces. We build what happens inside them.

You’ll work across the stack — frontend, backend, databases, APIs, AI, automation and cloud infrastructure — and collaborate with product, design and business teams to turn ideas into reliable, production-ready solutions.

What You’ll Build

- Build responsive web applications using React, Next.js, TypeScript, Python and Angular.
- Develop backend services and REST APIs using Node.js, Express.js and FastAPI.
- Design databases and data models using PostgreSQL, MongoDB, Prisma, SQLModel and related technologies.
- Integrate LLMs, AI agents, RAG, embeddings and document-processing workflows into real applications.
- Build background jobs and workflow automation using technologies such as Kafka, Camunda, Redis, BullMQ or Temporal.
- Integrate authentication, role-based access, payments, email services and cloud storage.
- Deploy and maintain applications on AWS using Docker and CI/CD pipelines.
- Write tests, review code, troubleshoot production issues and improve application performance.
- Work closely with product, design and delivery teams to plan, build and ship features.

What You Need to Bring

- Proven experience building and deploying full-stack applications.
- Strong JavaScript/TypeScript fundamentals with hands-on React experience.
- Experience developing REST APIs and backend services.
- Good understanding of relational databases and data modelling.




- Working knowledge of Git, code reviews and collaborative development.
- Ability to write clean, maintainable code and communicate technical concepts clearly.

Good to Have
- Next.js, Angular, Tailwind CSS, shadcn/ui
- Python, FastAPI, GraphQL, Socket.IO, Microservices
- LangChain, RAG, AI Agents, Qdrant
- AWS, Docker, Kubernetes, GitHub Actions, GitLab CI/CD
- Kafka, Temporal, Camunda, BullMQ, Redis
- Exposure to mobile applications, sensor-integrated systems or interactive installations

AI Engineering — Your Edge

Experience with any of the following will be a strong advantage:

- OpenAI, Gemini or open-source LLM integrations
- LLM applications, RAG, embeddings, vector databases and AI agents
- Machine-learning fundamentals including data preparation, training, validation and evaluation
- Model development or fine-tuning using PyTorch, TensorFlow or Hugging Face
- Dataset preparation, model evaluation and output testing
- AI model deployment and inference using Docker or cloud platforms
- Prompt engineering, structured outputs and responsible AI practices

What We’re Looking For

We’re not looking for someone who only writes frontend code or only experiments with AI.

We’re looking for an engineer who can move from:

Idea → Architecture → Code → AI Integration → Deployment → Production and take ownership of the result.

Why Join Rubenius?

Work on products and digital experiences that combine software, AI, automation and interactive technology across a design-and-build environment.

You’ll have the opportunity to work across disciplines, solve real business problems and contribute to products from development through deployment.
