• We believe that team events during working hours play a vital role in building an exceptionally effective team, and we encourage them
• We are enthusiastic about technology and committed to using it to improve the world
• We follow the "You build it, you run it" approach and take pride in it

What You’ll Be Doing

• Build High-Impact Solutions: Spend ~60% of your time as a hands‑on contributor, leading the implementation of scalable backend services and AI-native applications
• Technical Problem Solver: Act as the technical "special forces" across 2-3 high-priority teams, solving the most complex architectural puzzles
• Bridge Prototype to Production: Partner with PMs and ML engineers to turn experimental AI ideas into high‑availability, production‑grade services
• Own the AI Lifecycle: Take "You build it, you run it" ownership of the end‑to‑end pipeline from data retrieval (RAG) and ingestion to monitoring token usage, cost, and latency
• Architect Agentic Systems: Design and build complex conversational states, multi‑agent communication protocols, and the infrastructure that supports them.
• Technical Leadership: Champion engineering excellence. Influence the org’s technical direction by building prototypes and setting the standard for AI development at Staffbase

What You Need To Be Successful

• 10+ years of Experience: A proven track record in backend software development, including previous experience in a Tech Lead or Staff Engineer capacity
• Backend Mastery: Expert-level proficiency in GoLang in microservice architecture
• AI in Production: Hands‑on experience building, deploying, and scaling AI-native applications in a production environment (not just local experiments)
• Infrastructure Expertise: Deep knowledge of cloud platforms (Azure preferred) and container orchestration (Docker, Kubernetes)
• Distributed Systems: Strong understanding of event-driven architectures and high-concurrency systems

Preferred Experience

• AI Operations (AIOps): Experience with LLM observability and evaluation frameworks (e.g., Langfuse, Arize Phoenix, or custom "Golden Dataset" evals)
• Efficiency Expert: Proven ability to optimize RAG pipelines for both latency and cost (e.g., semantic caching, prompt engineering, or model distillation)
• Agentic Frameworks: Familiarity with building multi-agent workflows (e.g., using LangGraph, CrewAI, or similar)
• Developer Tooling: Experience building internal SDKs or libraries that help other engineering teams adopt AI features faster

What You’ll Get

• Competitive Compensation – we offer attractive salary packages including LTIP (unit-based Long Term Incentive Plan)
• Flexibility – we offer flexible working time models and the option of hybrid work, and support this with a yearly flex work allowance of €1560
