Associate/Fullstack Architect

Job Description

We are looking for a hands-on Technical Lead Engineer (Full Stack) to spearhead the design, development, and delivery of our scalable web platforms and core application ecosystems. In this role, you will bridge the gap between front-end experiences and robust back-end systems. You will lead an agile development team through technical architecture, feature implementation, integration, testing, deployment, and production support.

The ideal candidate has deep technical expertise in both frontend and backend modern frameworks, a passion for system design, and practical experience building secure, scalable, and high-performance distributed web applications.

Key Responsibilities

• Technical Leadership: Lead end-to-end full-stack software development, architectural design, and system evolution.
• Backend Architecture: Design scalable, fault-tolerant backend architectures, optimizing high-volume data ingestion pipelines and processing engines.
• Frontend Excellence: Direct the development of highly responsive, intuitive, and modular user interfaces that ensure a seamless user experience.
• API & Integrations: Architect secure RESTful APIs and integrate external enterprise platforms, third-party microservices, and identity providers.
• Team Mentorship: Mentor developers, run strict code reviews, define engineering best practices, and guide sprint-level execution.
• Data & Messaging: Maintain and optimize relational, NoSQL, and time-series databases alongside message queues for real-time application events.
• Production Ownership: Own technical troubleshooting for live production bottlenecks, system latency issues, and deployment bugs.
• Documentation: Create clean technical documentation, structural architecture diagrams, and system deployment guidelines.

Required Skills

• Experience: 6+ years of software development experience with at least 2+ years leading engineering teams or owning technical delivery.
• Backend Core: Advanced hands-on experience with Java, Spring Boot, Spring Cloud, multithreading, and REST API development.
• Frontend Core: Mastery of modern JavaScript/TypeScript frameworks (such as React, Angular, or Vue.js), HTML5, and responsive CSS architectures.
• Data Platforms: Proficient with relational databases (MySQL, PostgreSQL) and NoSQL/Caching systems (Redis, MongoDB).
• Messaging Systems: Experience implementing asynchronous workflows using message brokers like Kafka or RabbitMQ.
• Design Patterns: Strong grasp of microservices patterns, distributed system caching, load balancing, and failover mechanisms.

Preferred / Nice-to-Have Skills

• Experience deploying workloads to Cloud environments (AWS, Azure, or GCP).
• Familiarity with containerization tools like Docker and orchestration via Kubernetes.
• Hands-on experience setting up continuous integration and automated deployment pipelines (CI/CD).
• Exposure to system observability tools (Prometheus, Grafana, ELK stack).

Education Requirement

• Bachelor's degree in Computer Science, IT, Electronics, Electrical Engineering, or a related field. Candidates with equivalent exceptional hands-on full-stack engineering experience will be highly considered regardless of formal degree background.

About Techjays

At Techjays, we build production-grade AI platforms for global clients. We operate at the intersection of backend engineering, distributed systems, and applied AI — delivering secure, scalable, and enterprise-ready intelligent systems. 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
