At
5Plus
(part of Pentadoc Group), we build
production-grade AI systems
that solve real operational problems for our customers.
As a
AI Engineer
(m/f/d), you will
take technical responsibility for customer-facing AI solutions
— from early design decisions to production deployment and operation. You will design, build, and operate AI applications ranging from
LLM-powered workflows
(e.g., intelligent document processing, RAG systems) to
agentic AI systems
that are actively used in customer environments.
German language
skills at
C1 level
and above are
mandatory
for this role.
You’ll work closely with customers and internal engineers to translate ambiguous requirements into reliable, scalable systems and guide AI-driven product development within customer projects. This role is
hybrid
, with
predominantly remote work
and
occasional on-site presence
at customer locations across Germany and our office in Würzburg, Bavaria.
Your profile
Several years (3–6)
of hands-on experience building and operating
AI/ML systems in real-world projects
.
- Solid experience implementing agents on the
LangChain stack
(
LangGraph
,
DeepAgents
) in
Python
, including
FastAPI
interfaces.
- Experience with
AWS
(e.g.
ECS
,
CDK
, …)
Strong Python expertise (
app.
5 years)
and experience with modern AI/LLM tooling; framework-agnostic mindset.
- Proven experience with
LLM-based systems
(e.g., RAG, embeddings, tool usage) and an understanding of trade-offs between quality, cost, latency, and complexity.
- Ability to work
independently in customer-facing environments
, taking ownership of technical decisions under uncertainty.
- Professional communication skills in customer contexts.
- Residence in
Germany
.
Bonus points to score
- Deeper experience with
agentic architectures
(planning, memory, multi-agent coordination).
- Contributions to open-source projects, technical writing, or applied research.
Your daily business
- Design and ship end-to-end AI systems, from prototype to production.
- Build LLM-powered applications (incl. RAG, tool usage, validations) with a focus on reliability and cost-efficiency.
- Develop and operate agentic AI systems (e.g., planning, tool orchestration, multi-step workflows) with clearly defined safety and integrations into customers’ systems.
- Define evaluation strategies (offline + online), including metrics, benchmarks, and monitoring.
- Optimize system performance across latency, cost, and quality.
Take technical leadership within customer project teams
, coordinating architecture, implementation, and iteration cycles.
- Act as a
technical point of contact for customers
, explaining trade-offs and guiding solution decisions.
- Work directly with customers and internal teams to turn ambiguous, real-world problems into concrete AI solutions.
- Contribute to architectural decisions and
support less-experienced engineers through technical guidance
(no people management).
