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
