Zalion is an international AI start-up revolutionizing industrial procurement. We use cutting-edge AI agents to automate manual Source-to-Pay processes, freeing up procurement teams for strategic work.
We are live with the largest companies in Europe & the US.
We love what we do. We get stuff done. We progress fast.
Tasks
- 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.
Requirements
- 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.
Benefits
- Build AI agents that actually do things
- Massive autonomy, zero bureaucracy
- Immediate impact, your work ships fast to real customers
- Modern stack, no legacy
- Competitive salary + meaningful equity
- High-end equipment
🛠️ Tech Stack You’ll Work With
- 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
- Postgres , Redis
- Large Language Models (LLMs) and AI infrastructure (evaluation, tracing, guardrails)
- Whatever the future brings that helps us ship faster and better
