Job Description

As Java Backend Architect at Atradius, you will define and guide the architecture of Java-based backend services, APIs, microservices, and reusable integration components. Working closely with enterprise architecture, cybersecurity, DevOps, engineering teams, and product stakeholders, you will translate business and platform needs into secure, scalable, maintainable technical solutions. In this role, you will set backend architecture principles, promote modern Java frameworks and engineering practices, review solution designs, and provide technical leadership to teams delivering mission‑critical backend services.

Responsibilities

In this position, your key responsibilities will be:

Java Backend Architecture & Modern Frameworks

• Define target architectures for Java backend services, microservices, APIs, and reusable integration components, ensuring alignment with enterprise architecture and platform standards.
• Design scalable, resilient, and maintainable backend solutions using modern Java frameworks and patterns, including Spring Boot, Spring Cloud, Quarkus, Micronaut, Jakarta EE, RESTful services, asynchronous messaging, and event‑driven integration where appropriate.
• Establish backend architecture principles covering modularity, clean architecture, domain‑driven design, dependency management, performance, scalability, and long‑term maintainability.
• Define and promote API design standards, including contract‑first design, OpenAPI documentation, versioning, error handling, pagination, idempotency, lifecycle management, and backward compatibility.
• Review technical designs and implementation approaches to ensure consistency, code quality, performance, security, observability, and operational readiness across backend and API solutions.
• Guide teams in selecting the right backend framework and architecture approach based on workload, deployment model, maintainability, runtime performance, and enterprise standards.

Backend Security, APIs & Operational Excellence

• Embed security‑by‑design principles into Java backend and API solutions, including authentication, authorization, secure communication, secrets management, input validation, secure coding, and dependency vulnerability management.
• Define and review API security patterns such as OAuth2, OpenID Connect, JWT, mTLS, API gateways, rate limiting, threat protection, access control models, and integration with enterprise identity providers.
• Collaborate with cybersecurity teams to assess vulnerabilities, security findings, penetration test results, and remediation plans affecting backend services, APIs, shared components, and integration of assets.
• Promote observability, structured logging, distributed tracing, monitoring, alerting, and operational readiness standards for Java backend services and API platforms.
• Support performance, scalability, resilience, availability, and fault‑tolerance assessments for critical Java services, APIs, and integration flows.
• Ensure architecture decisions consider compliance, auditability, data protection, risk management, and secure operation in cloud‑native and containerized environments.

Technical Leadership & Stakeholder Engagement

• Act as a senior technical reference for Java backend, API, integration, and backend security topics across delivery teams.
• Provide architectural guidance, mentoring, and technical coaching to engineers, helping teams make sound design and implementation decisions.
• Facilitate architecture discussions, design reviews, proof‑of‑concepts, and technical decision records with clear rationale and trade‑offs.
• Collaborate with product owners, solution architects, enterprise architects, cybersecurity, DevOps, and operations teams to align technical solutions with business and platform objectives.
• Contribute to technical roadmaps, modernization initiatives, platform standards, and continuous improvement activities for APIs and backend services.
• Stay current with Java, API management, cloud‑native, DevSecOps, and backend security trends, assessing their relevance for Atradius.
