Pleo is a spend-management platform for businesses that provides company cards, automated expense management and configurable spend controls. Its product messaging highlights AI-powered reviews, card limits, approval flows and other tools to manage corporate spending for small, medium and enterprise customers. Pleo is delivered as software to help finance teams control, track and automate business expenses and card usage.

📋 Description

• Design, build, and operate core GenAI platform components used by product teams at Pleo, including LLM routing gateway, vector search and RAG infrastructure, tool registry and MCP gateway, AI observability and evaluation tooling (tracing LLM calls, supporting human and automated evaluation, detecting drift, and tracking costs) and infrastructure for multi-step, long-running agentic workflows. • Own production-quality delivery of platform features, from design through rollout, monitoring, and follow-up. • Contribute to resilient system design: sensible APIs, failure handling, rate limiting, retries, idempotency, and safe change management. • Improve reliability and observability through metrics, dashboards, alerting, incident follow-ups, and operational improvements. • Partner with Applied AI Engineers and product teams to understand platform needs and help them build AI-powered features safely. • Build internal SDKs, templates, and guardrails that let product engineers build AI features without needing deep infrastructure expertise. • Support other engineers through pairing, code reviews, technical feedback, and clear documentation. • Help evaluate build-vs-buy decisions in the rapidly evolving LLMOps tooling landscape.

🎯 Requirements

• Strong backend/systems engineering background, with experience building and operating production services with reliability and observability requirements. • Experience designing and delivering shared platform or infrastructure components used by multiple teams. • Strong production ownership: monitoring, alerting, incident response, debugging, and post-incident learning. • Distributed systems fundamentals, including async workflows, idempotency, consistency tradeoffs, and designing for failure. • Hands-on experience with LLM APIs or strong interest in learning their production failure modes: rate limits, context windows, multi-vendor routing, latency variance, and cost control. • Security mindset for AI systems, including prompt injection risks, PII in logs, data leakage, and safe credential handling. • Strong programming experience in either a JVM-based language or Python. We operate a polyglot platform with components written in both Kotlin and Python, and you’ll be expected to contribute to both. • Clear communication and collaboration skills, especially when working with product teams and other engineers to turn ambiguous platform needs into practical solutions.
