Arbetsbeskrivning

Turn ship physics into software people actually use

At Cetasol we build the monitoring and analytics platform that commercial fleets use to cut fuel consumption, understand how their vessels really perform, and stay on the right side of CII and EU MRV reporting. A growing part of that platform is predictive maintenance: catching when an engine, generator, thruster, or the vessel as a whole starts behaving differently than it should, before it becomes a failure.

Getting there takes two things that rarely live in the same person: an understanding of the physics behind how these assets actually behave, and the engineering skill to ship that understanding as a working product.

We're looking for that person.

What you'll do

• Build physical and data-driven models of vessel assets — engines, generators, thrusters, and the ship as a whole — that capture what "normal" operation looks like
• Detect when an asset deviates from its expected behaviour, and trace that deviation back to the sensors and signals driving it
• Work with noisy, real-world sensor data from vessels: clean it, validate it, and decide what it can and cannot support
• Take your own models from notebook to production on AWS, and build the React interfaces where the results actually land in front of customers
• Own features end to end, with our UX designer, full stack developers and data scientist alongside you
• Help us decide where a first-principles model beats a statistical one, and where it doesn't

What we're looking for The balance here is genuinely 50/50. You should be comfortable deriving a model and deploying it.

On the modelling side:

• Strong applied mathematics, physics or engineering foundation — fluid dynamics, thermodynamics, control theory, numerical methods, or similar
• Experience with anomaly detection or condition monitoring on physical systems — knowing how to separate a genuine fault signature from normal operating variation
• Solid Python and the usual scientific stack; experience with time series and sensor data
• The judgement to know when a model is good enough and when it's fooling you

On the engineering side:

• Practical experience building and running services on AWS
• Comfortable in React and modern frontend work — you don't need to be a specialist, but you should be able to build the view your model deserves
• Familiarity with the ordinary craft of software: version control, testing, code review, CI

And:

• You explain technical work clearly to people who aren't specialists
• You're happy to sit somewhere between disciplines rather than in the middle of one

We're open on years of experience. If you can do the work, the title follows.

Nice to have Predictive maintenance or condition-based monitoring · maritime, automotive, aerospace or energy domain experience · digital twins or physics-informed machine learning · edge computing or embedded data collection

Why Cetasol

Shipping accounts for roughly 3% of global CO₂ emissions, and a meaningful share of that is avoidable through better operational decisions. The work here is technically interesting and the impact is measurable in tonnes of fuel.

• You'd be joining a small engineering team where your work is visible and your scope is wide. We're based in Gothenburg and work hybrid — we value time in the same room, without counting days.
