Job Description

We’re looking for a Senior Backend Engineer with strong experience in Java (Spring Boot) and/or Go, who enjoys working on distributed systems, understands real-world trade-offs, and leverages AI tools to move faster and smarter

This is not just about writing code — it’s about building resilient systems, making solid technical decisions, and shipping with confidence.

What you’ll be doing

• Design, build and scale distributed backend systems using Java and/or Go

• Work deeply with microservices architectures, understanding trade-offs and system design decisions

• Implement and maintain event-driven systems and messaging solutions

• Collaborate on CI/CD pipelines and deployment strategies

• Contribute to architecture discussions, bringing clarity and pragmatic thinking

• Use AI tools (Copilot, ChatGPT, Claude, etc.) to accelerate development and problem-solving

What we’re looking for

Technical Expertise

• Strong, hands-on experience with Java (Spring Boot) and/or Go

• Proven experience building and scaling microservices-based systems

• Solid understanding of:

  • Idempotency

  • Service discovery

  • Resilience patterns (retries, circuit breakers, etc.)

Messaging & Distributed Systems

• Experience with messaging systems (Kafka, RabbitMQ, NATS, etc.)

• Deep understanding of:

  • Consumer groups

  • Dead-letter queues

  • Delivery guarantees ( at-least-once vs exactly-once)

DevOps Mindset

• Experience working with CI/CD pipelines

• Familiarity with deployment strategies:

  • Blue/Green

  • Canary

  • Feature Flags

AI-Driven Productivity

• Comfortable using tools like GitHub Copilot, ChatGPT, Claude (or similar)

• Ability to integrate AI into daily workflows to improve speed and quality

What makes you a great fit

• You think in systems, not just code

• You’re comfortable discussing trade-offs, not just “best practices”

• You care about reliability, scalability, and maintainability

• You’re proactive, autonomous, and own what you build

Nice to have

• Experience with cloud platforms (AWS, GCP or Azure)

• Exposure to high-throughput systems

• Background in event-driven architectures

Advanced English is required, as you’ll work directly with US-based clients in a fully collaborative environment 🇺🇸

🚀 What we offer

• 20 days of paid time off per year

• Flexible working hours (we care about results, not clocking in)

• Remote-first culture

• Health insurance + fitness benefit

• Learning & development support

• In-company English classes

• Internal knowledge-sharing sessions

• A collaborative, friendly, and human-centered team environment
