Overview
At apeirum we exist to turn bold visions into digital realities with focus sharp execution and no waste. But what really sets us apart is how we work together :
* We stick together. No one is left alone with a tough challenge. We back each other up share knowledge and solve problems as a team.
* We push each other forward. Growth is part of our DNA whether thats learning new tech improving processes or challenging each other to aim higher.
* We win together. Success is collective. Every contribution matters and every team member has a visible impact on the product and the client.
Life at apeirum is not about bureaucracy endless meetings or overpromising. Its about building real solutions that last learning constantly and having the autonomy to do your best work. Youll find space to experiment colleagues whove got your back and leadership that values transparency and trust.
Currently we are seeking support for our client an innovative start-up to build the factories of tomorrow. Theyre redefining smart for manufacturing SMEs with Industrial IoT data and cloud solutionsmoving from visibility to optimization to AI-driven decision support.
In this role youll design and implement services that connect real factory systems (IoT ERP MES) with scalable cloud components. Youll make sure our solutions run reliably in production : clean code CI / CD observability and pragmatic use of AI where it adds value. We value engineers who are self-driven collaborative and transparent (I dont know yetlets figure it out together beats over-promising).
Location : Spain (remote-first). Preference for North of Spain (Galicia Asturias Cantabria Basque Country). No profiles outside Spain. Occasional travel to Switzerland and within Spain.
Process : Intro team chat tech deep-dive short practical final chat.
Responsibilities
* Build and maintain backend services & APIs in Python and C# (.NET).
* Integrate with IoT / ERP / MES systems and cloud components (Azure preferred).

* Ensure observability (logging tracing metrics) and production readiness.
* Collaborate closely with domain experts and teammates to turn prototypes into stable maintainable products.
* Contribute to architecture discussions and bring a pragmatic devops mindset.
* Experiment with AI / LLM components where useful but keep the focus on robust engineering.
IN YOUR FIRST 90 DAYS YOU MIGHT
* Ship a small Python or C# service that connects to an ERP / MES system.
* Set up CI / CD pipelines and monitoring for a new production component.
* Deploy a cloud-native service with proper authentication and alerting.

NICE TO HAVE
* Microservices development experience (e.g. Dapr Kafka Redis).
* Retrieval-Augmented Generation (RAG) workflows or vector search integration.
* Exposure to industrial / edge tech (OPC UA MQTT) time-series data or IoT.
* Experience with Kubernetes Terraform or infrastructure as code.
* Basic knowledge of AI / LLMs and when to use them (but not mandatory).
* German language skills.
Benefits
