Software Architect Backend

Job Description

We are looking for a highly experienced and technically strong Software Architect tojoin our backend team.

Software Architect is responsible for designing and evolving the technical architecture of backend services, with a primary focus on Java, Spring Boot, distributed systems, and domain-oriented design. In this role, you will translate complex business and product requirements into scalable, maintainable, and high-quality architectural solutions, ensuring long-term sustainability, performance, and reliability across systems.

As a Software Architect, you will collaborate closely with engineering teams, product managers, QA, DevOps, and peer architects to establish architectural standards, guide best practices, and ensure alignment across teams. You will drive the design of modular and scalable backend systems, oversee service architecture, APIs, data flows, and integration patterns, and ensure that software solutions are secure, observable, and aligned with both business and engineering objectives.

If you are curious by nature, adaptive, collaborative, and always one step ahead, then join us and be a Commencer!

Responsibilities

• Providing active hands-on architectural guidance and leadership through the entire lifecycle of backend products and services
• Designing backend architectures using Java, Spring Boot, and related technologies in alignment with scalability, maintainability, performance, and security goals

• Collaborating closely with other architects, engineering managers, and development teams across the organization in architecting and delivering robust backend solutions
• Structuring and delivering technical documentation for HLDs, architecture decision records, solution designs, analysis inputs, API contracts, sequence diagrams, and backend design artifacts, and establishing standard practices for co-workers to adapt easily
• Investigating and assessing emerging technologies, backend frameworks, and architectural patterns to determine the best approach for product and platform needs
• Defining non-functional requirements from availability, scalability, security, observability, extensibility, and operational support perspectives, and designing backend solutions to meet those requirements
• Supporting teams in troubleshooting system-level backend, integration, performance, data consistency, and production issues
• Designing and guiding API-first, event-driven, and asynchronous integration patterns between internal and external systems
• Driving architectural decisions for distributed systems including resilience, retries, idempotency, fault tolerance, transaction boundaries, caching, and messaging patterns
• Reviewing and improving service boundaries, backend code structure, data access patterns, deployment architecture, and technical debt areas
• Developing and leading proof-of-concept projects for backend frameworks, platform capabilities, and architectural improvements
• Driving discussions with senior co-workers regarding trade-offs, best practices, project delivery risks, and backend modernization strategies
• Cross-training peers and mentoring teammates on software design principles, backend architecture patterns, and engineering standards
• Conducting code reviews and design reviews, and providing feedback to team members with a focus on backend quality attributes and architectural sustainability
• Assisting in technical audits and ensuring audit recommendations are implemented in line with secure software development and platform standards

• Strong knowledge of software architecture patterns such as layered architecture, hexagonal architecture, clean architecture, modular monoliths, and microservices
• Experience with domain-driven design, domain modeling, and designing systems across different domain structures and business capabilities
• Experience with containerization and orchestration frameworks such as Docker and/or Kubernetes
• Working knowledge of application and system availability, scalability, observability, and distributed data platforms
• Expertise in backend performance optimization, transaction management, concurrency handling, and scalable system design
• Experience with relational database design, SQL optimization, and data consistency patterns, with additional familiarity in non-relational and NoSQL databases
• Experience with messaging and streaming technologies such as Kafka, RabbitMQ, or similar platforms
• Expert-level understanding of CI/CD principles, knowledge of various tools, and strong focus on engineering quality gates and delivery practices
• Knowledge of cloud services, especially AWS and related AWS services
