Overview

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.

Role Description

• 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

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
