Embedded Software Engineer, Marine CAN & Onboard Linux

X Shore; Nyköpings kommun; On-site; SEK 600,000 - 900,000; Full time

Job summary

X Shore is seeking an Embedded Software Engineer to build and maintain software for our electric boats. You will own from firmware on control units to services on the onboard gateway, ensuring verifiable operation on target hardware.

The role is hands-on with on-site days in Nyköping and a hybrid work model. You will develop, test, and document software, contribute to CAN networks, and collaborate across hardware and software teams.

Qualifications

• Solid programming skills in C, applied to embedded targets.
• Working knowledge of Python.
• Comfortable with AI tools in daily development, and able to review and verify what they produce.
• Confident with Git in a team setting.
• Practical experience with CAN bus — development, integration, or diagnostics.
• Hands-on with hardware: flashing, probing, measuring, and building simple test setups without waiting for someone else to do it.
• Able to read a schematic well enough to work with electrical engineers on bring-up and fault-finding.
• Fluent in English; Swedish is an advantage.
• Able to be on-site in Nyköping on a regular basis.

Responsibilities

• Develop and maintain embedded software in C for onboard control units, and in Python for tooling, diagnostics, and test automation.
• Design, implement, and debug CAN-based communication between onboard systems, including NMEA 2000 traffic.
• Test your own code on target hardware — on the bench, on test rigs, and on boats.
• Build the test setups, harnesses, and simple rigs needed to verify the code when no test environment exists.
• Take part in bring-up of new hardware together with electrical engineering.
• Debug field issues together with service: read logs and CAN traces, reproduce the fault, and deliver a fix.
• Maintain build, flashing, and provisioning tooling so releases are reproducible and traceable.
• Own the interface documentation for the systems you work on — message definitions, signals, parameters, and service procedures.
• Take part in code reviews and technical discussions across the software team.
• Support production with end-of-line test and software procedures on the line.
• Contribute to release decisions by stating clearly what has been verified, on which hardware, and what has not.
• Feed lessons from delivered boats back into the software — better diagnostics, better logging, fewer repeat visits.
