Full Stack AI Engineer

Remote (Europe) | Full-time | Experienced Hires

Zalion is on a mission to eliminate repetitive procurement work through agentic AI. We’re building autonomous agents that operate deep within enterprise procurement — navigating messy data, legacy systems, and complex workflows to deliver real impact.

Join us early and help define how enterprise AI is done right.

🚀 What You’ll be responsible for

You will:

Own and ship agent-powered features end-to-end – from idea and prototype to production rollout and iteration.

Design, build, and deploy AI agents in production that interact with real systems (ERPs, email, supplier portals) and deliver measurable outcomes.

Work with both structured and unstructured data (RFQs, emails, quotes, contracts) to power memory, retrieval, and decision-making.

Build scalable memory, reasoning, and orchestration pipelines using tools like LangChain/LangGraph and evaluation frameworks.

Integrate with external APIs and legacy systems , dealing with real-world messiness, rate limits, and failure modes.

Contribute to our cloud infrastructure for scalable agentic workloads (observability, CI/CD, reliability, cost-awareness).

Solve hard problems around context management, latency, robustness, and guardrails – making agents debuggable and trustworthy, not magic.

You’ll work closely with the founders and early customers to understand real procurement workflows and turn them into robust, AI-native product experiences.

Python (LangChain, LangGraph, LangSmith, FastAPI)

AWS (Bedrock, ECS Fargate, Lambda, S3, SQS/SNS)

Next.js , React , TanStack Query/Router

GitHub CI/CD , Sentry & Grafana & Prometheus

Large Language Models (LLMs) and AI infrastructure (evaluation, tracing, guardrails)

Whatever the future brings that helps us ship faster and better

✅ What We’re Looking For

Strong Python skills and a track record of writing clean, maintainable, well-tested backend code

Solid experience designing and building RESTful APIs and data models in production environments

Experience with data engineering concepts (ETL, data quality, performance) and backend architecture

Hands-on experience building something real with LLMs (OpenAI, Claude, etc.) – side projects are fine as long as they’re concrete

Comfort working in the cloud (ideally AWS) with CI/CD, logging, and monitoring

A builder mindset – you like to ship small, iterate quickly, and own your work end-to-end

Comfort with ambiguity and ownership : you spot problems, propose solutions, and drive them to completion without waiting for perfect specs

Roughly 4+ years of professional experience, including at least one role where you owned a production service, subsystem, or major feature.

Build AI agents that actually do things

Immediate impact, your work ships fast to real customers

Competitive salary + meaningful equity

High-end equipment

We’re looking for someone who has already shipped real systems to production — but we care more about what you’ve built and how you think than your exact number of years. If you're excited about autonomous agents and backend challenges, and owning features end-to-end — let’s talk.

Links to things you’ve built (GitHub, blog posts, talks, etc.)
