Lead Engineer - AI Studio

Jobtailor; Deutschland; Vor Ort; EUR 120.000 - 180.000; Vollzeit

Zusammenfassung

Jobtailor is seeking a senior backend architect in Germany to lead the technical direction for our AI Studio app-builder architecture and mentor engineers building the app generation engine.

You will partner with product, infra, and design to shape the roadmap, and design scalable, low-latency systems supporting high-throughput generative workloads with modern tech such as Go, Node/NestJS, PostgreSQL, and Cloudflare.

Qualifikationen

• 6+ years of backend engineering experience including distributed system design and high-scale platform development.
• Strong proficiency in Go (Golang) for building high-performance, concurrent backend services, alongside Node/NestJS experience.
• Hands-on experience building and operating edge/serverless services with Cloudflare Workers and Cloudflare KV (or comparable edge compute and distributed key-value stores).
• Deep expertise in event-driven architectures, asynchronous workflows, and high-throughput data pipelines.
• Strong command of relational (PostgreSQL) and NoSQL data models, query optimization, and complex transactional data.
• Fluency in LLM integrations, vector search, embeddings, RAG patterns, and generative AI frameworks.
• Familiarity with frontend architecture using Vue, and a solid understanding of UI/UX principles.
• Experience with monitoring, alerting, and incident response for production systems.
• Strong instincts for scaling, latency optimization, and reliability under real-world load.
• Experience implementing structured generation, verification layers, retrieval-based grounding, and guardrails to reduce hallucinations.
• Understanding of prompt engineering patterns, context injection, and model evaluation.
• Exceptional communication and cross-functional leadership capabilities.
• Pragmatic decision-making with a balance of long-term vision and iterative execution.

Aufgaben

• Drive the technical direction for our AI-driven application-builder architecture.
• Lead complex system design decisions.
• Serve as a hands-on technical leader and mentor for the engineers building AI Studio’s app generation engine.
• Partner with product, infra, and design to shape the roadmap.
• Build scalable, fault-tolerant LLM pipelines for content generation, layout creation, experimentation, and AI-driven user guidance.
• Work hands-on with technologies like Go, NestJS, Node, PostgreSQL, Firestore, vector databases, Cloudflare Workers, Cloudflare KV, and microservices.
• Design distributed systems that handle high-throughput generative and analytical workloads while ensuring correctness and low latency.
• Drive improvements in observability using Prometheus/Grafana, OpenTelemetry, and structured logging.
• Mentor engineers through code reviews, design discussions, and pairing.
• Participate in reviews, deep dives, and on-call rotations to maintain a culture of accountability and operational excellence.
