On the Ledger side that means commission terms, revenue splits, and the contracts between developers, sellers, and the platform. On the Promotion side it means coupons, promo codes, redeem codes, and gift cards, and the acquisition and gifting models built on them.\nYou’ll work with complex business logic, third-party integrations, and existing systems, collaborating closely with product and engineering teams. We’re looking for someone curious, proactive, and responsible who enjoys learning, taking ownership, and improving solutions.\nOur back-end stack: Go, Temporal, PHP 8.0+ (Symfony Components, Doctrine ORM); PostgreSQL, Redis, RabbitMQ; PHPUnit; Cloud-Native: AWS, GCP, K8s, Docker.\nIn this role, you will:\nOwn the solution design end to end: take an ambiguous business task, propose how the system should evolve, defend it in a peer design review, and then build it\n\nModel new commercial concepts for Ledger and Promotion capabilities so they stay consistent with the rest of the platform's domain model\n\nWork closely with PMs, EMs, and cross-functional teams to clarify requirements, handle edge cases, and find the most effective implementation paths\n\nGradually refactor and migrate parts of the monolith into independent, high-performance services\n\nTake full responsibility for code quality by writing Unit/Functional tests and actively participating in E2E testing (our engineers drive quality alongside QA)\n\nWrite clean, efficient, and scalable code using Go and PHP (Symfony)\n\nSkills you’ll need to bring:\n5+ years building production services in Golang\n\nSolution and system design as a primary skill\n\nDDD in practice: bounded contexts, aggregates, when to split a service, and why a shared database isn't a boundary\nConfident work with PostgreSQL/relational databases: schema design, complex SQL queries, migrations, and performance optimization (indexes, profiling)\n\nExperience with RabbitMQ (or similar message queues): pub/sub and work queue patterns, producers/consumers, basic configuration concepts\n\nAPI design: resource modeling, versioning, idempotency keys, error contracts, backward compatibility for public APIs\n\nGo depth: concurrency and graceful shutdown, detecting data races and goroutine leaks, pprof, table-driven testing\n\nDocker, plus working knowledge of Kubernetes objects and probes\n\nCI/CD, feature flags, trunk-based development, safe migrations\n\nObservability: logs, metrics, traces, SLI/SLO/SLA\n\nAwareness of secure coding principles (OWASP)\n\nAt least an intermediate English and fluent Ukrainian\n\nAs a plus:\nWorkflow orchestration (Temporal or similar) for compensation and retries in long-running money flows\n\nPHP (Symfony), since parts of the current system still live there\n\nTerraform, Redis,
