Role Description Join us as an AI Platform Engineer (AppCompass, Devex & Cloud Enablement Team) to own the AI capabilities layer, working at the intersection of AI infrastructure, developer experience, and platform engineering. - Operate and evolve the centralized LLM Gateway that routes all company AI API traffic (Cursor, Claude Code, Kiro, Toqan, LUMI), with disaster recovery runbooks and SLA enforcement (≥ 99.5% uptime). - Instrument observability through Langfuse — latency, cost per model tier, error rates, and usage patterns. - Enforce AI license and access policies (Cursor seat limits, agentic tool controls) through self-service tooling. - Build RAG pipelines and develop MCP servers. - Track AI adoption across the SDLC and own the AI Skills Marketplace and AI Guilds coordination tooling in Backstage. - Build the Slash AI Assistant — a natural language interface over Backstage and internal tooling. - Own the AI Incident Investigator feature — cross-system analysis across GitLab, Jira, and monitoring through Backstage. - Integrate AI capabilities into the self-service action catalog and productionize agentic workflows (tool-use, multi-step reasoning, agent orchestration). - Maintain audit trails for AI tool usage and data classification compliance. - Build the AI Adoption Best Practices guide and surface it through Backstage. Qualifications - 3+ years of backend or platform engineering experience (TypeScript/Node.js or Python). - Hands-on experience with LLM APIs (OpenAI, Anthropic, Gemini) — building integrations, not just prompting. - Understanding of API gateway patterns, observability, and cost instrumentation. - Familiarity with Docker/Kubernetes and CI/CD (GitLab CI preferred). - Experience with Langfuse, LangChain, or similar LLM observability/orchestration tools. - Experience with MCP (Model Context Protocol) server development. - Agentic workflow design (tool-use, multi-step reasoning, agent orchestration). - Background in developer productivity, DevEx, or platform engineering teams. - Experience with React/TypeScript for frontend plugin development. - Experience building or extending Backstage plugins, or equivalent internal developer portal work. - You think in systems, not features, and you're comfortable navigating the moving target of agentic AI tooling. - You measure your own impact — cost saved, adoption rate, uptime — and document what you build so others can extend it. Benefits - Medical subscription: Medicover or Regina Maria. - A flexible budget that you can invest in yourself as you wish: meal tickets, holiday tickets, cultural vouchers, private pension, foreign language classes, eMAG, Fashion Days, Therme & Genius, membership to different gyms or even professional development classes. - Different discounts from our partners: banking, mobile, dental medicine, or wellness. - Access to the Bookster library and free credits on the Hilio psycho-emotional health platform. - An accelerated learning environment, with access to over 100,000 curated online resources and platforms, learning academies, and development programs. - New headquarters, where sleek design, natural light, and versatile spaces create an energizing and comfortable environment for hybrid work.
