Job Description

As a Senior Software Engineer, you will design, build, and operate full-stack features across a Java/Spring Boot microservices backend and a React/TypeScript frontend. You will own end-to-end delivery — from database schema and API design through UI implementation — and collaborate with product, QA, and other engineering teams to ship reliable, production-grade software. This role combines hands-on technical depth with the leadership to mentor junior engineers, raise the engineering bar, and drive sound architectural decisions across the stack.

  • Design, develop, and maintain features across the full stack — Java/Spring Boot microservices and React/TypeScript frontend

  • Own end-to-end delivery of features from database schema through API to UI

  • Build and optimize RESTful APIs, WebSocket real-time communication, and inter-service messaging via RabbitMQ

  • Write and maintain database migrations, optimize PostgreSQL queries, and manage Redis caching strategies

  • Collaborate with product and QA to define requirements, estimate effort, and deliver iterative improvements

  • Participate in code reviews, architectural discussions, and incident response

  • Contribute to CI/CD pipelines, observability, and deployment processes

Requirements

Required Skills

Backend (Primary)

  • 5+ years of professional experience with Java (Java 17+, ideally Java 21)

  • Strong proficiency with Spring Boot 3.x, Spring Security, and Spring Cloud

  • Experience building and maintaining microservices architectures — service decomposition, API gateway patterns, inter-service communication

  • Solid understanding of PostgreSQL — schema design, indexing, query optimization, migrations (Flyway or Liquibase)

  • Hands-on experience with message brokers (RabbitMQ, Kafka, or similar) for event-driven architectures

  • Experience with Redis for caching, session management, or pub/sub patterns

  • Familiarity with OIDC/OAuth2 authentication and RBAC authorization models

  • Strong unit and integration testing practices — JUnit 5, Mockito, Testcontainers

Frontend

  • 3+ years of professional experience with React (v16+) and TypeScript

  • Comfortable with React Context API, custom hooks, and component composition patterns

  • Experience consuming RESTful APIs and working with WebSocket/STOMP for real-time UIs

  • Understanding of responsive design and mobile-first development

  • Familiarity with build tools like Vite or Webpack

General

  • Strong grasp of REST API design principles and experience with OpenAPI/Swagger documentation

  • Experience with Git workflows (feature branches, pull requests, code reviews)

  • Ability to read and write SQL comfortably — not just ORM queries

  • Strong debugging, profiling, and troubleshooting skills across the stack

  • Clear written and verbal communication in English

Required Experience and Qualifications

  • Bachelor’s degree or equivalent combination of education and directly related experience.

  • 5+ years of professional experience in full-stack software design and development

  • Proven track record of delivering production-grade microservices and modern web applications

  • Experience working in agile, cross-functional teams across global time zones

Desired Skills and Experience

  • Experience with Docker and Docker Compose for local development and production

  • Experience with CI/CD pipelines (Bitbucket Pipelines, Jenkins, GitHub Actions)

  • Familiarity with observability stacks — Grafana, Loki, Prometheus, or similar

  • Experience with WebSocket horizontal scaling (Redis Streams, Redis Pub/Sub)

  • Experience with Playwright or Cypress for E2E testing

  • Exposure to k6 or JMeter for load/performance testing

  • Experience with OWASP security scanning or SonarQube code quality tools

  • Knowledge of Change Data Capture (CDC) patterns or data replication pipelines

  • Working with AI coding assistants like Cursor or Claude Code
