Zusammenfassung

Atos/Eviden in Vienna is seeking a Lead Software Developer to drive mission-critical backend communications. You will lead an agile team, design scalable, low-latency services and mentor engineers.

The role emphasizes AI-assisted workflows, event-sourced CQRS architectures, and secure, high-availability systems, with hybrid work from Wien HQ. Strong leadership and a Go-first background are valued.

Qualifikationen

• Experience Minimum 7+ years in software engineering, with at least 2 years in a technical leadership or team-lead capacity.
• Language Proficiency 5+ years of hands-on experience building enterprise-grade systems in at least one of Go, C++, Java, C#. Go strongly preferred (or proven ability to ramp quickly to a Go-first stack).
• Distributed Systems Mastery Proven experience designing and operating horizontally scalable architectures and event-driven systems (Kafka, RabbitMQ, or similar).
• Event Sourcing & State Practical experience with event-sourced and/or CQRS architectures, deterministic state machines, and replay-based recovery.

Aufgaben

• Leadership & Mentorship Provide technical, hands-on leadership to the software engineering team, ensuring alignment with architectural best practices.
• Modern Engineering & Agentic Development Champion the adoption of AI-assisted coding tools and agentic development workflows to automate repetitive tasks, accelerate feature delivery, and raise quality - while establishing the guardrails that keep AI-generated code correct, reviewed, and production-safe.
• High-Availability Architecture Lead the design and evolution of a horizontally scalable, cloud-native services architecture optimized for 99.999% uptime and zero single points of failure.
• Real-Time Distributed Computing Design and implement resilient, event-driven systems built on high-throughput distributed messaging (e.g., Kafka, RabbitMQ) to handle concurrent data and media streams.
• Event-Sourced State Management Architect event-sourced services and CQRS-style read/write models with deterministic, replayable state - ensuring auditability and consistent recovery across nodes.
• Security & Data Protection Drive security-by-design across the platform encryption in transit and at rest, key management, authentication/authorization, and secure handling of sensitive traffic in regulated, high-assurance environments.
• Programming Excellence Drive high code quality standards, leveraging deep expertise in a fully-fledged backend language (Go, C++, Java, C#) while establishing validation guardrails for AI-generated code.
• Orchestration & Containerization Oversee containerization strategies and manage complex service orchestration.
• High-Performance Networking Implement secure, fast service-to-service communication protocols, optimizing for low-latency network performance and efficient data serialization.
• Performance Engineering Actively identify architectural bottlenecks, troubleshoot complex distributed-tracing issues, and optimize services for sub-second response times and high concurrency.
• Cross-Functional Alignment Collaborate closely with Product, QA, and DevOps teams to ensure seamless CI/CD execution and timely delivery of critical features.
