Staff Backend Engineer - Active Journey Alliance

Nasze wymagania: Agentic Engineering: Strong hands-on experience working with AI coding agents (e.g., Claude Code, Cursor, Copilot) in production or near-production environments. You think beyond prompts to context engineering, structuring specifications, tool configurations, and information flow so agents produce reliable results. You can reason about how to decompose complex workflows across multiple agentic components and identify when agentic outputs are unreliable, diagnosing problems to improve outputs in an iterative way. You have strong processes around adding guardrails, both in understanding where and when they’re needed and how to implement them. 8+ years of backend engineering experience with deep expertise in microservices and distributed event-driven architectural patterns Expert-level proficiency in at least one of the programming languages: Go, PHP, and/or JVM languages Proven track record of leading large-scale technical projects and driving architectural decisions in complex distributed systems Advanced experience with Docker, Kubernetes, and cloud-native architectures, including production operations at scale Extensive experience building event-driven architectures using message bus technologies (Kafka, RabbitMQ, SQS/SNS, etc.) Deep expertise with database technologies (relational and NoSQL), including performance optimization, schema design, and operational best practices Demonstrated ability to mentor engineers and drive technical standards across teams Excellent communication and collaboration skills, with experience working with senior stakeholders and distributed teams GraphQL experience for client-backend integration is a plus Zakres obowiązków: Work on the architecture, design, and technical strategy for complex microservices systems, establishing patterns and best practices across multiple teams.
