Senior Embedded Software Engineer

At Everllence, we transform cutting‑edge technology into solutions that help decarbonize global trade. As the world’s leading provider of energy‑efficient and fuel‑flexible large marine engines, we are driving the transition toward greener shipping.

You will join the embedded software team in the Automation department in Copenhagen. The team develops firmware and middleware that connects the two‑stroke control application with the control system hardware.

The engine control system is a highly distributed embedded platform where multiple controllers communicate over dual‑redundant Ethernet networks using PRP (Parallel Redundancy Protocol) to ensure deterministic, zero‑loss failover. Each controller is built on proprietary hardware, featuring an AMD UltraScale processor running an open‑source RTOS to execute control algorithms and interface with sensors, actuators, and user interfaces.

You will play an important role in:

As a Senior Embedded Software Engineer, you will develop, extend, and maintain firmware and middleware across key platform components running on a range of processors, including ARM Cortex‑R5. This includes updates and improvements to the open‑source RTOS, new hardware interfaces, and other core platform services.

This platform provides the foundation that enables application teams to develop efficient control algorithms, support multiple fuel types, and implement advanced emission reduction technologies.

Your primary responsibility will be designing and developing embedded software that connects application layers with hardware. You will:

Contribute across the full development lifecycle, from requirements and architecture to implementation and maintenance

Build interfaces to actuators and sensors communicating over various protocols

Design and implement automated tests to ensure robustness and quality

Analyse, troubleshoot, and improve existing solutions

Improve internal tools, ways of working, and CI/CD pipelines

Collaborate with hardware and application teams to ensure seamless integration

We imagine that you:

A degree in software engineering, computer science, electrical engineering, or a related field, or equivalent practical experience

Experience in embedded software development (typically around 8+ years, though equivalent experience is also valued)

Solid experience with C and C++

Hands‑on experience developing embedded software on RTOS‑based systems

Understanding of or experience with cybersecurity in embedded systems (e.g., IEC 62443 or similar)

A collaborative approach, with the ability to work independently and take ownership when needed

Interest in solving complex technical challenges

Strong communication skills and the ability to work with a range of stakeholders

Experience with or interest in using AI‑driven tools such as Copilot, Claude, or similar to improve productivity, quality, and automation across the software development lifecycle

Welcome to the embedded software team

We care about well‑being and foster a relaxed, informal atmosphere where it is easy to collaborate and exchange ideas. You will work closely with skilled engineers who are passionate about embedded systems and take pride in building robust, high‑performance solutions.

The team shares knowledge openly, supports each other’s development, and continuously evolves the platform. If you enjoy working on complex challenges, discussing architecture, and learning with others, you will feel welcome here.
