Java Backend Engineer

Position Description:
We are looking for a strong Senior Java Backend Engineer to join our engineering team and help build scalable, reliable, high-quality backend systems for our platform. This role is for someone with deep expertise in Java and Spring Boot, strong system design capability, and excellent engineering fundamentals.
The right candidate is not just someone who can write backend code. We want someone who can think through architecture, design clean services and APIs, make sound technical decisions, and build systems that are maintainable, performant, and production-ready. This person should be highly comfortable working in a modern backend environment involving microservices, distributed systems, integrations, data flows, and real-world scale.
You will play a key role in designing and building backend services, improving system reliability and performance, reviewing technical designs, and helping raise the engineering bar across the team. This is a strong fit for someone who enjoys solving hard backend problems, building clean systems, and taking ownership of backend-heavy product and platform initiatives.
Roles and Responsibilities:
Design, build, and maintain backend services and APIs using Java and Spring Boot
Own the design and implementation of scalable, reliable, and maintainable backend systems
Translate product and business requirements into sound backend architecture and technical solutions
Design clean service boundaries, data flows, integration patterns, and API contracts
Contribute to system design for microservices, distributed systems, and backend workflows
Write clean, efficient, well-structured, and production-quality code
Review code and technical designs with a high bar for quality, maintainability, and performance
Troubleshoot complex production issues and drive root cause analysis and long-term fixes
Improve backend performance, reliability, scalability, and observability
Work closely with product, frontend engineers, DevOps, and leadership to deliver complete solutions
Help identify and reduce technical debt while improving engineering standards and backend architecture
Contribute to best practices in testing, monitoring, documentation, and software delivery
Mentor junior and mid-level engineers through strong technical guidance and code review
Participate in architectural discussions and help shape backend engineering decisions across the platform
Qualifications:
Strong professional experience in Java backend development
Deep hands-on experience with Spring Boot
Strong experience designing and building backend APIs and service-based architectures
Strong system design skills with the ability to think through scalability, reliability, performance, and maintainability
Experience building and working with microservices and distributed systems
Strong understanding of software design principles, object-oriented design, and clean code practices
Experience with relational databases, data modeling, and query optimization
Strong debugging and problem-solving ability in production environments
Experience with concurrency, transactions, integrations, and backend performance optimization
Ability to independently own backend-heavy technical initiatives from design through deployment
Strong communication skills and ability to explain technical decisions clearly
Ability to thrive in a fast-moving product environment with high ownership and accountability
Preferred Qualifications
Experience with event-driven architecture, Kafka, RabbitMQ, or similar messaging systems
Experience with AWS, Kubernetes, Docker, CI/CD, and cloud-native backend systems
Experience with observability and monitoring tools for production systems
Familiarity with security, authentication, authorization, and API protection patterns
Experience in B2B SaaS or high-growth product engineering environments
Experience mentoring engineers and contributing to technical leadership within a team
What Success Looks Like in This Role
You design backend systems that are clean, scalable, and easy to maintain
You can independently own complex backend features and services end to end
You improve system quality, performance, and reliability over time
You raise the engineering bar through strong technical judgment, clean implementation, and high-quality code reviews
You are someone the team trusts for backend architecture, problem-solving, and execution.
