WHAT YOU CAN EXPECT 

Full-Stack Ownership & Modernization 

• Take ownership of both backend (Java/Oracle) and frontend development within the project. 

• Contribute to the transition phase, including knowledge transfer from the external supplier and stabilization of existing systems. 

• Drive modernization initiatives across the stack — from the legacy ExtJS frontend to the Java/Oracle backend — and address performance bottlenecks. 

• Actively contribute to architectural decisions spanning backend services and frontend applications. 

Software Design & Development 

• Design, build, and maintain scalable, maintainable, and high-performing software across the full stack. 

• Design, implement, and maintain scalable, modular, and accessible UI components. 

• Ensure clean integration between backend services and frontend applications, following API-first and BFF patterns. 

• Apply best practices in coding, security, performance, and technical debt management. 

Partnering with Product & Design 

• Collaborate with Product Managers and Designers to validate ideas, estimate effort, and assess feasibility. 

• Balance business needs with technical realities when implementing solutions. 

Delivery & Execution 

• Deliver high-quality, production-ready features reliably and on time, end-to-end. 

• Support CI/CD pipelines and containerized deployments (Docker) for backend and frontend. 

• Ensure high code quality through TDD, code reviews, and automated testing. 

• Help identify and mitigate technical and operational risks early. 

Innovation & Experimentation 

• Support rapid prototyping and technical validation before full implementation. 

• Support A/B testing and iterative development. 

• Stay current with emerging technologies and suggest improvements. 

Backend Engineering (Java / Oracle) 

• Help stabilize a large legacy Java/Oracle application and support its gradual modularization over time. 

• Develop and maintain Oracle stored procedures and triggers implementing business workflows and logic. 

• Work with large, complex database schemas (1000+ tables), including schema design and migrations. 

• Design and implement REST APIs; integrate with internal and external systems. 

• Build file-processing capabilities (XML, CSV, Excel) and asynchronous workers/background jobs. 

Frontend Engineering 

• Contribute to frontend features, primarily using modern frameworks as part of the roadmap to replace the legacy ExtJS frontend. 

• Design accessible, responsive UI components. 

• Optimize applications for performance, accessibility (a11y), and SEO. 

WHAT YOU BRING ALONG  

Architecture & System Design 

• Understanding of cloud-native, distributed systems (microservices, DDD, event-driven, micro-frontend architectures). 

• API-first mindset; experience with API Gateway and Backend-for-Frontend (BFF) patterns. 

• Familiarity with resiliency, scalability, and observability patterns. 

Backend Engineering 

• Highly proficient in Java SE and modern Java coding principles. 

• Experience with the Spring Framework (not Spring Boot) — e.g. Spring Core, MVC, and Context. 

• Experience working on large, complex Java projects with extensive dependencies, using Maven (lifecycle and modules). 

• Skilled in database modeling (SQL & NoSQL); strong hands-on experience with Oracle (stored procedures, triggers, complex schemas 1000+ tables, migrations). 

• Proficient with Hibernate and Liquibase. 

• Builds REST APIs (OpenAPI); experience with event-driven services (Kafka, RabbitMQ, NATS) is a plus. 

Frontend Engineering 

• Strong proficiency in JavaScript and/or TypeScript. 

• Experience with at least one modern frontend framework (React, Angular, Vue.js, Svelte). 

• Development of modular, scalable, responsive UI components. 

• Focus on accessibility (a11y), performance optimization, and SEO. 

• Prior exposure to ExtJS is a plus, not required. 

Quality & Security 

• Applies OWASP, secure coding, and threat-mitigation practices. 

• Strong in TDD, unit/integration/E2E testing, code reviews, and static analysis. 

• Advanced knowledge of Git and version control workflows. 

Cloud, DevOps & Automation 

• Hands-on with AWS/Azure/GCP, cloud networking, and IAM. 

• Strong with Docker, Kubernetes, CI/CD pipelines, and Infrastructure as Code. 

• Experienced with monitoring and observability tools (Prometheus, ELK/EFK, OpenTelemetry). 

Collaboration & Professional Skills 

• Strong communication and stakeholder interaction skills. 

• Ownership-driven, customer-centric mindset. 

• Ability to learn quickly and adapt to change. 

• Strong problem-solving and time-management skills.
