Our team has built and scaled products at Google, Akamai, NetApp, ADP, Cognizant, and Capgemini.
About the Role
This is not a feature-delivery role. We are looking for an AI Lead who can architect, own, and scale intelligent backend systems end-to-end. You will drive both technical direction and execution — working across LLM integrations, RAG pipelines, agentic AI workflows, and cloud-native backend systems for global clients.
What You'll Do
- Architect and scale backend systems powering AI-driven applications
- 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
Role : Java Developer
Location : Bangalore

Over 1.8 billion non-salaried informal sector workers globally, and roughly 700m Indians are
not eligible for pension or other social protection benefits. Without an urgent and effective
response to pension exclusion, they face the grim prospect of extreme poverty for over 20
years once they are too old to work.
pinBox is the only global pensionTech committed exclusively to mass-scale digital micropension inclusion among self-employed women and youth. We deploy our white-labelled,
API-enabled pension administration and delivery platform, our unique deployment model and
a simple and intuitive UI/UX to make access to regulated pension, savings and insurance
products easy and simple for non-salaried informal sector workers. We're working actively
with governments, regulators, multilateral aid agencies and leading financial inclusion
stakeholders in Asia and Africa. The pinBox model is already operating in Rwanda, Kenya
and India. We will expand to Bangladesh, Uganda, Chile, Indonesia and Nigeria by 2023.
Governments and pension regulators use the our pensionTech to jumpstart digital micropension and insurance inclusion among informal sector workers. Pension funds and insurers
use our pensionTech to build a mass market for their products beyond their traditional agentled customer base. Banks, MNOs, cooperatives, MFIs, fintech firms and gig-platforms use
our plug-and-play pensionTech to instantly offer an integrated social protection solution to
their clients, members and employees without any new investments in IT or capacity
enhancement.
We’ve recently completed our first equity fundraise to enhance our engineering, business
and delivery capacity and embark on the next stage of pinBox pensionTech development
and expansion. By 2025, we aim to enable and assist 100 million excluded individuals to
start saving for their old age in a secure, affordable and well-regulated environment.

solve difficult, real-life problems at scale across multiple countries.

(consistent and thoughtful patterns, improved observability, unit and integration testing,
etc.),
5. Adhere to national and global architecture standards, risk management and security
policies,
