Senior Backend Engineer - Plans Squad

Nasze wymagania: Strong backend engineering experience, including modernizing monolithic legacy systems into microservices, and event-driven architectures. Hands-on experience with event-driven systems (e.g., Kafka) and real-time lifecycle event processing. Proven ability to design orchestration layers for complex end-to-end customer flows. Proficiency in Golang (JVM/Kotlin and PHP are a plus), plus experience with PostgreSQL, Docker, Kubernetes, and CI/CD pipelines. Solid understanding of TDD/BDD/DDD and distributed systems; experience with e-commerce, subscriptions, and GraphQL is a plus. Solid hands-on experience working with AI coding agents (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents as thought partners to onboard on unfamiliar codebases and navigate new areas of the code with confidence. You have a practical sense of how the context you provide to AI tools - specifications, constraints, examples - shapes output quality, and a developing awareness of how agentic outputs can fail, with growing habits around verifying, testing, and setting boundaries on AI-generated work.
