• improving system resilience and uptime
• making architectural decisions and setting technical direction

In the first months, you’ll deliver key tax functionality and lay a solid foundation for future product and team growth.

We rely on automated testing over manual QA — unit, integration, functional, and e2e tests are a core part of how we ship and scale safely.

You’re a great fit if you have

• 4+ years of backend engineering experience
• 1.5+ years of commercial Go development
• Strong understanding of high-load system design
• Solid experience with PostgreSQL
• Experience with queues or streams
• Strong testing culture: unit, integration, functional, e2e

• Proactive, independent, result-oriented mindset

   

Nice to have

• Kafka
• AWS services
