- Design and implement RAG pipelines, AI agents, and LLM integrations
- Own systems end-to-end — from architecture to deployment and scaling
- Integrate and optimize LLMs (Claude, GPT, Gemini) for real-world production use cases
- Build high-performance distributed systems with observability and cost efficiency
- Lead backend and AI initiatives with strong technical ownership
- Mentor engineers and raise the technical bar across teams
- Collaborate with product and AI teams to deliver AI-native solutions
What We're Looking For
- 6–10 years of strong backend engineering experience
- Hands-on expertise in Python (FastAPI / Django / Flask)
- Deep understanding of Generative AI and LLM-based systems
- Strong experience with RAG pipelines and Vector Databases (Pinecone, FAISS, ChromaDB, Weaviate)
- Solid knowledge of Agentic AI — building autonomous agents and multi-agent workflows
- Proficiency in AWS or GCP in production environments
- Experience with distributed systems, microservices, and system design
- Strong grasp of Data Structures, Algorithms, and Design Patterns
- Familiarity with WebSockets, Git, Linux/Unix, and CI/CD
Nice to Have
- Experience with Anthropic Claude API and Claude Code
- Familiarity with real-time data systems or streaming (Kafka, etc.)
- MLOps and AI system lifecycle experience
- Optimizing AI systems for latency, cost, and scalability
Who You Are
- You think in systems, not just features
- You take full ownership of what you build
- You are comfortable navigating fast-moving, ambiguous environments
- You stay updated with the latest in Generative AI and backend technologies
- Strong communicator who can collaborate across teams and global clients
What We Offer
- Competitive compensation (Best in Industry)
- Work on production-grade AI systems used by global clients
- Exposure to cutting-edge AI tools and frameworks
- A culture that values clarity, integrity, and continuous growth

Planning to Apply? Consider this:
Make sure you go through this section very carefully before applying. Here are the most crucial aspects on which we evaluate on:
1: FIT: “We’re on a crusade for something greater than any one of us”!
We are a tight-knit team that works and plays together where ‘fit’ is the most important point that you need to keep in mind while evaluating us- we will be spending a majority of our time together, in office, on calls, even weekends (sometimes) so you’ll really need to assess whether this is the right place for YOU to be in. Are you able to relate to or feel passionate about the problems we’re solving?
2: INTENT: “You won’t just be working with us, you would be investing in us!”
‘Why’ do you want to work with us? Why an early stage startup? Why Original4Sure? We are an industrious team, working tirelessly to achieve our goals so the work hours will be long and with it will come with a steep learning curve. Joining an early stage startup also means you’ll be asked to take on new things with little guidance and you’ll have to figure stuff out on your own, and in doing so, help shape the future of the company. Does that sound scary, exciting, both?
3: CAPABILITY: “Get work done!”
As long as you are working as hard as you can and giving it your best all day, every day, we will get along just fine. No one ever built one of the most valuable businesses in the World without the core team having to make a few sacrifices along the journey. It could be lesser time spent with your family or loved ones or finding lesser time to do to watch TV shows! But that's a call you need to make.
