AI Software Engineer (m/f/x)

Your Mission

At Simply Deliver & Rail-Flow, you will build AI-powered solutions that enhance transport management and offer processes. Your work will make rail freight more efficient, competitive, and sustainable—supporting the shift from road to rail and helping cut CO₂ emissions.

• AI Feature Delivery: You are able to design and implement robust AI features for the TMS Offer Module, including AI agents for planning, customer service, pricing, lane recommendations, and automated tender responses.
• RAG/LLM Pipeline Engineering: You are able to build and optimize RAG/LLM pipelines—document ingestion, chunking, embeddings, vector search, prompt orchestration, and structured output parsing.
• Evaluation, Safety & Guardrails: You are able to create and maintain golden datasets, enforce content filters and guardrails, and instrument telemetry for cost, latency, and quality.
• Engineering Excellence: You are able to write production-grade, testable code, collaborate on architecture, and automate tests and reliability drills for AI flows.
• Data & Privacy-by-Design: You are able to operationalize data pipelines, apply privacy and security best practices, and ensure tenant isolation and consent policies.

Your Profile

• Education & Experience: You have 5+ years in software engineering, with at least 3 years of hands-on experience building LLM/RAG or ML-backed applications in production (not just hobby projects).
• Technical Skills: You are proficient in Python, TypeScript, or Java, and experienced with microservices, APIs, event-driven patterns, LLM frameworks, and vector search.
• Data & Evaluation: You have strong data skills (schema design, ETL, feature pipelines) and deep understanding of evaluation methods (golden datasets, A/B tests, accuracy, grounding rate, latency, cost).
• Security & DevSecOps: You are skilled in PII handling, tenant isolation, access control, CI/CD, automated testing, and performance optimization.
• Collaboration: You have excellent communication and documentation skills, and can translate business needs into AI solution designs.
• Preferred: Experience in transportation/logistics, optimization/OR, cost optimization for AI workloads, and building guardrails/safety systems is a plus.
