Entrylevel Java Backend Developer Jobs in Belleville, NJ

We are sharing a specialised part-time consulting opportunity for experienced backend engineering professionals with strong backgrounds in API development, microservices, database architecture, query optimisation, distributed systems, and scalable server-side engineering.

This role supports current and upcoming remote consulting opportunities focused on backend engineering evaluation, technical scenario review, systems design, API architecture, database performance, and production-grade engineering workflows. Selected professionals may apply experience across backend services, distributed architectures, data models, system reliability, integration patterns, and real-world software engineering practices.

Key Responsibilities

Professionals in this role may contribute to:

API Development & Backend Services

• Review backend engineering tasks involving API design, service architecture, authentication flows, request handling, and integration patterns
• Assess REST, GraphQL, RPC, or comparable API scenarios for clarity, correctness, maintainability, and practical relevance
• Evaluate backend logic, service boundaries, data flow, error handling, and production-readiness
• Provide structured feedback on technical accuracy, implementation quality, and engineering judgment

Microservices & Distributed Systems

• Review scenarios involving microservices architecture, distributed services, event-driven systems, queues, messaging patterns, and service communication
• Evaluate system design choices related to scalability, latency, consistency, reliability, fault tolerance, and observability
• Identify architectural gaps, unclear assumptions, or weak technical reasoning in backend system scenarios
• Contribute practical expertise on designing and maintaining scalable backend platforms

Database Architecture & Optimisation

• Assess database schema design, indexing strategies, query performance, data modelling, and transactional behaviour
• Review tasks involving SQL, NoSQL, caching layers, replication, sharding, and backend data access patterns
• Evaluate trade-offs related to performance, consistency, storage design, and long-term maintainability
• Provide feedback on database architecture and optimisation decisions based on real-world backend experience

Technical Documentation & Scenario Review

• Support the development, review, or refinement of backend engineering tasks and technical deliverables
• Provide clear explanations and feedback based on hands-on engineering experience
• Review technical materials for accuracy, completeness, and practical usability
• Help ensure outputs reflect real-world backend engineering standards and production system expectations

Ideal Profile

Strong candidates may have:

• Professional experience in Backend Engineering, Software Engineering, Systems Engineering, Platform Engineering, or related technical roles
• Hands-on experience building APIs, backend services, microservices, databases, and distributed systems
• Strong familiarity with server-side languages such as Python, Java, Go, JavaScript/TypeScript, C#, Ruby, PHP, or comparable technologies
• Experience with relational and non-relational databases, query optimisation, caching, message queues, and service integration patterns
• Ability to evaluate technical workflows, identify practical issues, and explain backend engineering reasoning clearly
• Strong written communication skills and comfort working independently in a remote, project-based environment

Educational Background

• A degree in Computer Science, Software Engineering, Information Systems, Computer Engineering, or a related technical field is helpful
• Equivalent professional experience in backend engineering, software architecture, distributed systems, or production software development is also highly relevant

Nice to Have

• Experience with AWS, GCP, Azure, Docker, Kubernetes, Terraform, CI/CD pipelines, or cloud-native backend systems
• Background in systems design, high-scale applications, distributed databases, event-driven architecture, or backend reliability
• Experience with PostgreSQL, MySQL, MongoDB, Redis, Kafka, RabbitMQ, Elasticsearch, DynamoDB, or similar technologies
• Experience creating technical documentation, evaluating engineering tasks, mentoring developers, or reviewing software architecture

Why This Opportunity

• Flexible, remote consulting work aligned with your backend engineering expertise
• Opportunity to contribute to technical projects involving real-world software architecture, APIs, databases, and distributed systems
• Suitable for experienced professionals who enjoy technical evaluation, structured feedback, and practical engineering problem-solving
• Project-based work that can align with part-time availability and remote schedules

Contract Details

• Independent contractor engagement
• Fully remote and flexible scheduling
• Part-time, project-based availability
• Expected commitment may vary by project, with many opportunities ranging from approximately 15–30 hours per week
• Competitive hourly compensation in the range of $60–$120/hour, depending on project scope, experience, and fit
• Payments are made weekly via Stripe or Wise based on services rendered
• Projects may be extended, shortened, adjusted, or concluded based on project needs and performance
• Candidates requiring H1-B or STEM OPT sponsorship support are not eligible at this time
• Work must not involve sharing confidential or proprietary information from any employer, client, or institution
