Acoustic Signal Processing Engineer
Do you get excited about turning raw acoustic and sensor data into meaningful insights? Are you excited by developing robust signal‑processing algorithms that bridge acoustics, applied science, and real‑world ML applications? If you’re passionate about building solutions that are both scientifically sound and computationally efficient, let’s connect!
At Fluves and Marlinks, we deliver cutting-edge monitoring solutions for critical infrastructure in the offshore wind, water supply and chemical sectors. Our monitoring applications support clients worldwide, and we need skilled engineers to deploy, configure, and maintain these essential services.
DAS technology turns fiber-optic cables into dense arrays of acoustic and vibration sensors, generating rich spatio-temporal data streams. Making sense of that data, detecting anomalies, classifying events, filtering noise and localising sources, is at the core of our company. You bring knowledge on how acoustic and vibrational signals propagate in physical systems, and you will apply that knowledge to building algorithms and models that are not just scientifically sound, but also interpretable, computationally efficient and deployable in an operational context.
YOUR ROLE
As an Acoustic Signal Processing Engineer you will:
- Design and implement signal processing pipelines for DAS data: filtering, denoising, feature extraction, beamforming, and event detection. Work on source localisation, anomaly detection, and classification of acoustic events;
- Develop physics-informed algorithms that exploit the acoustic and mechanical properties of subsea cables and water distribution networks;
- Collaborate with the delivery team to understand the physical context of the data you are processing;
- Translate your findings into production-ready components that integrate into our broader data platform, handling large data volumes efficiently and scalably on the edge;
- Stay current with state-of-the-art techniques in signal processing, evaluating their applicability, within the context distributed fiber sensing and our operational monitoring systems;
- Write production-quality code and, with an eye for opportunities to optimize performance-critical components;
- Actively engage in both product development as well as R&D projects in close collaboration with your colleagues of the product development team.
YOUR PROFILE
You are someone who brings technical expertise, hands-on experience, and a strong sense of ownership.
You have:
- A Masters or PhD degree in Physics, Acoustics, Electrical Engineering, Applied Mathematics, or related field;
- A solid understanding of acoustics and wave propagation in fluid and solid media;
- A strong background in digital signal processing theory (Fourier analysis, filtering, spectral methods, time-frequency representations, wavelet transforms…);
- Scientific rigor combined with agetting things done mentality: you can design experiments and commit to rigorous model validation with a pragmatic mindset to meet deadlines;
- The ability to communicate complex technical concepts clearly, document appropriately, be transparent and open;
- Proficiency in programming, in particular the scientific Python stack. Familiarity with software engineering good practices, including comprehensive unit testing, version control, CI pipelines, and documentation.
The following are a plus
- Experience with fiber-optic sensing (DAS, DTS, FBG);
- Familiarity with array signal processing or spatio-temporal data;
- Hands-on experience with acoustic sensing systems or underwater acoustics;
- Practical experience applying machine and deep learning to signal or sensor data;
- Exposure to embedded or edge deployment of signal processing pipelines;
- Experience using MLOps tools like MLflow;
- Publications, code repositories or projects demonstrating digital signal processing experience.
WHAT WE OFFER
- A role where your scientific knowledge genuinely matters
- Real-world impact: your algorithms will protect critical subsea infrastructure and help water utilities detect leaks
- A collaborative, intellectually open team where ideas are debated and curiosity is valued
- Flexibility: Hybrid working, requiring 2 or 3 days per week in the office in Ghent in accordance with company policy
- Competitive salary and benefits package, tailored to your experience
- The opportunity to grow with a company at an exciting stage: your work will shape how we scale
