Backend Engineer - Core Java

Gimmy Keil · India

Backend Engineer – Core Java | AI-Assisted Engineering

Location: Bengaluru, Chennai or Ahmedabad

Work Model: Hybrid – 2 days/week

Experience: 2–6 years

Engagement: 3-Month Contract (Extendable)

Joining: Immediate / Within 1 Week

We’re looking for a Backend Engineer with strong Core Java fundamentals to join a product engineering team working on business-critical backend services and customer-facing data integrations.

This is not a framework-heavy Java role. We’re looking for engineers who understand Core Java, backend architecture, microservices and scalable systems deeply and can independently take ownership of production features.

A key part of this role is also AI-assisted software development . You should already be using tools such as Claude, GitHub Copilot or Cursor as part of your daily engineering workflow — not simply experimenting with them.

What You’ll Work On

• Design and develop moderately complex backend features with minimal supervision.
• Build and maintain scalable backend services and microservices.
• Own business-critical production components from development through deployment and maintenance.
• Contribute to system design and architecture discussions.
• Build and maintain customer-facing connectors handling large volumes of data and events.
• Troubleshoot production issues, bugs and customer escalations.
• Implement security fixes and improve reliability of existing services.
• Use AI coding assistants to scaffold features, write tests, debug issues, review code and accelerate development.
• Break down engineering problems into precise tasks and prompts to get effective output from AI tools.
• Review and validate AI-generated code for correctness, security, performance and engineering standards before it reaches production.
• Write clean, maintainable and production-ready code.

What We’re Looking For

Must Have

• 2–6 years of hands-on backend software engineering experience.
• Strong and current Core Java expertise.
• Strong understanding of backend engineering fundamentals.
• Hands-on experience building Microservices .
• Experience designing and implementing moderately complex features independently.
• Ability to contribute meaningfully to system design and architecture discussions.
• Experience owning production systems/components and resolving real-world production issues.
• Experience working with scalable, distributed or high-volume backend systems .
• Experience in a product-based company , preferably B2B SaaS or B2C product environments.
• Hands-on, regular use of AI coding assistants such as Claude, GitHub Copilot or Cursor .
• Ability to effectively prompt AI tools, decompose engineering tasks and critically review AI-generated code before production use.
• Ability to join within 1 week .
• Must currently be based in or near Bengaluru, Chennai or Ahmedabad .

Good to Have

• Python development experience.
• Database/JDBC integration experience.
• Experience working with connectors, integrations or data-intensive backend systems.
• Experience with distributed systems or event-driven architectures.

Who This Role Is For

This role is ideal for a hands-on backend engineer who can operate independently , understands Java beyond frameworks, has worked on production-grade product systems, and is already incorporating AI into their daily coding workflow.

If your experience is primarily Java support, testing, maintenance or enterprise application configuration , this role is unlikely to be a fit.

Interested? Apply only if you meet the Core Java, Microservices, Product Company and AI-assisted development requirements.
