- Maintain device abstraction layers and transform data for internal use.
- Build reusable tools and templates for faster onboarding.

**Quality, Testing & Observability**
- Contribute to CI pipelines, testing frameworks, and system reliability checks.
- Improve system observability using Open Telemetry, metrics, and logs.

**Product Collaboration**
- Collaborate with product and core engineering teams to strengthen edge capabilities.
- Modularize and standardize configuration logic for scalability.

**What We’re Looking For**:
**Hard Requirements**
- Degree in Engineering (Software, Electrical, Telecommunications, or related fields).
- **3+ years of relevant experience in engineering or technical integration.**
- 2+ years of experience working with **Linux systems**(Ubuntu preferred).

- Excellent communication skills in English; able to collaborate across tech and non-tech teams.

***:
**Nice to Have**:

- Hands-on experience with industrial protocols like Modbus TCP/IP, OPC UA.
- Familiarity with AWS IoT, Open Telemetry, Kafka, or Grafana.
- Experience in SCADA systems, BESS, or other energy/automation environments.
- Background in monitoring, telemetry optimization, and config-driven device onboarding.

***:
**What’s in it for you**:

- A unique opportunity to contribute to the clean energy transition.
- A salary range between **€47,000 - €55,000 gross/year**, depending on experience.
- Be part of a fast-growing company with a highly talented, international team.
