What engineers work on

At Clemios, engineers work on technical systems for real-world applications. Every line of code must be traceable and verifiable.

  • Analyse technical requirements and translate them into documented development steps

  • Embedded firmware for EV chargers, gateways and industrial controllers using C/C++

  • Backend integrations and technical interfaces for connected systems

  • Validation and interoperability testing on real charging systems

  • Long-term system architecture for connected technical systems

How technical development works at Clemios

  • 1

    Engineers work directly with one another. No proxy layers and no account managers in between.

  • 2

    Clear ownership from design through validation. Develop, test, ship.

  • 3

    No artificial deadlines for demos. Quality and correctness matter more than speed theatre.

  • 4

    Technical decisions are documented, reviewed and recorded in a traceable way.

  • 5

    All work follows documented technical requirements: structured documentation, full traceability and systematic testing.

Who thrives at Clemios

A good fit for Clemios:

Value correctness and system behaviour

Work confidently across firmware, backend and protocols

Prefer clear technical discussions over vague alignment meetings

Want to understand entire systems, not just one part

Value production responsibility over conference-driven innovation

This role is less suited to people who:

Prefer exclusively greenfield projects without constraints

Prefer to avoid production responsibility

Expect strictly predefined task divisions with no ambiguity

Are looking for a remote-first, purely asynchronous work culture

About this role

This six-month trainee programme at Clemios provides practical foundations in embedded hardware and software development for connected technical systems such as EV chargers, gateways and industrial controllers. Participants work under the guidance of experienced engineers on real development tasks from circuit concept through firmware. Further collaboration may be considered for suitable participants after documented review.

Responsibilities

  • Learn the fundamentals of specifying and implementing hardware and software building blocks for embedded systems in an interdisciplinary team
  • Get familiar with analogue and digital circuit design and practise schematic and layout creation in the PCB design tool Altium Designer under guidance
  • Learn hardware commissioning in the lab and development-accompanying tests at the ESD test bench with oscilloscopes
  • Apply simulation-based circuit development with LTspice to validate hardware concepts before layout
  • Learn firmware development in C/C++ for microcontroller platforms and be introduced to the fundamentals of real-time operating systems (RTOS)
  • Get familiar with communication interfaces such as CAN, LIN, SPI, I2C, Ethernet, MQTT, Bluetooth/BLE and Profinet and apply them in guided tasks
  • Learn the fundamentals of motor control and control engineering for DC and BLDC drives (including FOC algorithms)
  • Learn version control with Git, CI/CD, automated testing and AI-assisted development tools
  • Learn requirements management and technical documentation in Polarion along the Clemios development process
  • Learn the fundamentals of functional safety in embedded systems development
  • Carry out module, integration and system tests including validation and documentation under guidance

Technical requirements

  • Basic C/C++ knowledge for microcontrollers
  • Understanding of electronic systems and communication protocols (SPI, I2C, UART)
  • Basic knowledge of PCB design and hardware-software integration
  • Initial exposure to analogue or digital circuit design is an advantage
  • Strong interest in embedded systems, eMobility and connected devices

Requirements

  • Completed bachelor's degree or completed technical vocational training in electronics, electrical engineering or mechatronics
  • Evidence of very good performance through study or training certificates and relevant transcripts to be submitted
  • Evidence of very good academic performance, for example a very good GCE Advanced Level or an equivalent school qualification
  • Education in English or in an English-speaking environment
  • Evidence of very good mathematics skills through certificates or comparable proof of training
  • Applicants residing in Cameroon

Programme benefits

  • Free accommodation and meals for the entire duration of the trainee programme
  • Hands-on experience with technical development tasks from circuit concept through to firmware
  • Access to lab equipment including an ESD test bench and oscilloscopes
  • Work with professional development tools (Altium Designer, LTspice, Polarion, Z2Data, Git, CI/CD, AI-assisted development support)
