Description

Join GoOpti and help shape the future of shared transport in Europe.

We’re GoOpti — a dynamic transportation platform helping tens of thousands of people move efficiently between cities and airports. Our system powers complex marketplace logic, real-time scheduling, and partner integrations — and it’s time to grow our backend team.

👨‍💻 The Role

We’re looking for a mid-level backend developer who’s not afraid to roll up their sleeves and dive into legacy Java code and help modernize and optimize key system components. You’ll work as part of a tight-knit team of 4 developers — we collaborate closely, review each other’s work, and share responsibility for code quality and system performance.

Requirements

🔧 What You’ll Work On

Maintain and evolve our Java-based monolithic system (Java 11, Spring Boot, Wildfly 24)
Build and refine REST APIs and integrate with our microservices (written in Java and C#)
Write clean, testable code and help improve coverage with unit tests and integration tests
Troubleshoot and resolve performance bottlenecks or scaling issues
Support gradual migration from monolith to microservices on AWS + Kubernetes
Participate in code reviews, team discussions, and product grooming sessions (Scrum)

🧠 Our Stack

Languages & Frameworks: Java 11 (Spring Boot), C#, JRuby (legacy frontend)
Infrastructure: AWS (EKS), Docker, Kubernetes, GitHub Actions (CI/CD)
Databases: MySQL, PostgreSQL (via AWS RDS)
Messaging: Kafka (MSK), RabbitMQ
Caching & Observability: Redis, DataDog
Security & DNS: Cloudflare, OAuth via Keycloak

We build domain-driven microservices around fleet optimization, pricing, geo-routing, financial clearing, and customer communication.

✅ What We’re Looking For

3+ years of experience as a backend developer (ideally with Java 8+)
Comfort working in large codebases and identifying legacy issues
Familiarity with REST APIs, SQL databases, Git
Experience with Docker/Kubernetes or willingness to learn
Proactive, collaborative mindset — you enjoy working as part of a small team
Solid communication skills in English; Slovenian is a plus

💡 Nice to Have

Experience with RabbitMQ, Kafka, or Keycloak
Knowledge of AWS infrastructure
Familiarity with performance profiling and optimization

🔍 The Practical Stuff

Remote-first (EU-based preferred for timezone overlap)
Expectation: Full-time, with occasional on-call (~2x/month)
Work language: English + optionally Slovenian
Real impact on a system used by thousands of customers daily

Benefits

🎁 What We Offer

Competitive salary based on experience and skills
Fully remote work with flexible hours (EU time zones preferred)
A supportive, close-knit development team — we help each other grow
Opportunities to work on complex architecture and real-world logistics problems
Impact — our software moves people across Europe daily
Regular team buildings and occasional in-person meetups
Continuous learning environment — we value ideas and initiative
25+ days of vacation, depending on location and agreement

If you enjoy technical challenges, making systems faster and cleaner, and working on something real and used — we’d love to hear from you.

Apply now and let’s build the future of smart intercity transport.
