Backend Java Developer | $60-$110/hr Remote
Overview
Your Java skills will shape how AI models learn and reason. In this remote contract role, you'll build and maintain backend services using Java and Spring Boot, with a strong focus on Microservices architecture. The customer's team depends on you to review technical specs, ship production-ready code, and jump in when something needs debugging or extra performance. No prior AI experience is required, so bring your deep backend knowledge and put it to work on real training data.
What You'll Do7
- 1Design, build, and maintain scalable Java backend services that support AI training systems.
- 2Architect microservices solutions that meet demanding application needs.
- 3Work alongside the customer's team to review technical specs and ship high-quality code.
- 4Bring expert insight to improve application performance, reliability, and security.
- 5Participate in code reviews and offer teammates clear, constructive feedback.
- 6Document technical processes and solutions in concise written explanations.
- 7Troubleshoot, debug, and tune backend systems when issues surface.
Requirements7
- 1Expert-level Java skills, including modern language features and common design patterns.
- 2Hands-on Spring Boot experience building production backend systems.
- 3Strong microservices design knowledge and real examples of applying it.
- 4A track record of writing clean, maintainable code that teammates can read easily.
- 5Exceptional written and verbal communication, with sharp attention to detail.
- 6Comfortable collaborating with remote, distributed teams and different time zones.
- 7Solid understanding of REST APIs, core data structures, and backend best practices.
Who Should Apply
Backend engineers who reach for Java and Spring Boot first and can explain their microservice choices with confidence will thrive here. The role is fully remote, so clear written updates and readable code matter a lot. If you're mostly a frontend developer or your Java experience is stale, this is probably the wrong fit. The biggest reasons people get screened out are shallow microservice design rationale and code that other maintainers can't follow easily. Cloud platform exposure (AWS, Azure, or Google Cloud) or a background in distributed, high-availability systems can help your case, but they are not required.
Salary Insight
The hourly rate for this contract role is $60 to $110, based on experience and skills.

VerifiedBackend Engineer ( Core Java, 3 Months Contract )
You own backend feature delivery on a 3-month contract in Chennai, steering work from system design conversations to code that reaches production. The core language is Core Java, and on any given day you touch microservices, database access, and JDBC integration paths. You sit with a group that builds data intelligence software for enterprises, where peers use Claude, GitHub Copilot, and Cursor as standard kit. Backend roles usually let you ignore AI tools; this one expects you to use them for scaffolding, writing tests, reviewing code, and debugging. What makes it different is the twin demand: ship at a faster cadence and still catch the errors in AI-written code before anyone else does.
