Job Title: Software Engineer II
- Backend & Applied AI

Location:
Gurgaon/ Full Time] Department: Engineering

About the Role
We are looking for a highly skilled Software Engineer to build the ultra-low-latency, event-driven systems that power our core platform, and to build the next-generation AI layer on top of them. You will operate at the intersection of correctness, latency, and scale. You won't just be building faster pipelines; you will be building systems that reason. In this role, you will bridge classical distributed systems (Kafka, Redis, microservices) with modern AI inference layers, deploying Applied AI and Agentic workflows over high-throughput operational data. If you are an engineer who cares more about why a system fails than why it works, and you prefer staring at flame graphs and Kafka consumer lag over building purely greenfield CRUD apps, this is the role for you. What You Will Do
• Architect High-Scale Backend Systems: Design and re-architect critical pipelines around event-driven processing to drive down processing times (e.g., from T+2 to T+0).
• Optimize for Performance: Radically reduce DB CPU utilization through query optimization, table partitioning, and Redis-backed caching strategies. Eliminate redundant queries and decouple databases to remove shared bottlenecks.
• Build Applied AI & Agentic Workflows: Develop LLM-powered workflows and RAG pipelines for transaction intelligence and anomaly detection.
• Design Autonomous Agents: Build agents utilizing tool-use, function calling, and multi-step reasoning that can dynamically decide when to query SQL versus retrieving from a vector store.
• Modernize Legacy Architecture: Lead the migration of legacy microservices (e.g., PHP to Java/Spring Boot) to cut latency and unblock future scaling.
• Evaluate & Monitor: Implement strict evaluation harnesses for AI retrieval quality (precision@k, MRR) and end-to-end agent reliability. Set up comprehensive dashboards and alerting (Grafana) for strict SLAs.
• Develop Reusable Frameworks: Design generic rule engines and auxiliary services to offload processing from core operational hot-paths. What We Are Looking ForExperience: 4+ years of software engineering experience, ideally in healthtech or healthcare industry Core Backend Stack:
• Deep expertise in Java and Spring Boot.
• Strong experience with Event-Driven Architecture using Kafka (or ActiveMQ).
• Proficiency in database architecture and caching: MySQL (optimization, partitioning) and Redis.
• Solid understanding of Microservices architecture and handling concurrency (producer-consumer patterns, worker-pools). Applied AI / ML Stack:
• Proficiency in Python and FastAPI for AI service layers.
• Hands-on experience with LLMs, Prompt Engineering, and APIs (OpenAI, Anthropic).
• Experience building RAG pipelines and working with Vector Databases (e.g., pgvector).
• Familiarity with AI orchestration frameworks like LangChain and LlamaIndex. Tooling & DevOps:
• Kubernetes, Docker, Linux.




• Strong testing practices using JUnit and Mockito (aiming for 95%+ coverage on critical paths). Observability and monitoring using Grafana. Who You Are
• A First-Principles Thinker: You know that prompts and models are the easy part of AI; you focus on the real engineering challenges of latency, cost, evaluation, and reliability.
• A Performance Nut: You are comfortable reading slow query logs and flame graphs to squeeze out every millisecond of latency.
• An Owner: You take full ownership of the reliability, latency, and cost of the systems you ship. We’re looking for a Founding Platform Engineer / Senior Staff Engineer to help architect and build the technology foundations of AviniaHCS.
