The core of our achievements is our team. We believe in people and shared values SELECT. That’s why, together with Vladyslav Kiriushkin - Engineering Manager at Platform tribe, we’re looking for a Senior Software Engineer to join our new team transforming the EdTech industry.
 

What will you do:

• Build and evolve backend services for a new mission-critical product, from MVP to broader adoption.
• Implement reliable transactional workflows: clear state handling, safe retries, and consistent data persistence.
• Integrate with external partners/systems and make integrations production-grade (edge cases, timeouts, partial failures).
• Ensure operational readiness: monitoring/alerting, debugging, incident participation, and performance improvements.
• Contribute to engineering standards: code quality, tests, documentation, and continuous delivery practices.
   

What do you need to join us:

• 5+ years of backend engineering experience;
• Strong backend fundamentals: API design, concurrency, databases, distributed systems basics
• Solid experience shipping and maintaining production services;
• Experience of integrating external systems/APIs, building robust adapters, and handling edge cases at scale
• Reliability mindset: observability, failure-mode thinking, and pragmatic testing.
   

Challenges you will face:

• Ambiguity of a new product: requirements will evolve as we validate the MVP, so you’ll need to iterate quickly and make pragmatic trade-offs;
• High correctness expectations: you’ll work on mission-critical flows where edge cases matter (retries, duplicates, partial failures, inconsistent partner responses);
• Operational ownership: you’ll help run what you build – monitoring, debugging, incident participation, and improving reliability over time;
• Balancing delivery and engineering quality: shipping fast while still keeping the codebase maintainable (tests, clear interfaces, documentation);
• Cross-team dependencies: progress may depend on aligning with other teams’ timelines and changes in existing systems, so communication and coordination are part of the job.
   

What do we offer:

• Work within an ambitious team on a socially impactful education product.
• An office with a reliable shelter, generators, satellite internet, and other amenities.
• Access to our corporate knowledge base and professional communities.
