Acoustic Signal Processing Engineer

Optics11AmsterdamHybridFull-time6 Oct 2026

Optics11 is expanding its Underwater Acoustics R&D team with an Acoustic Signal Processing Engineer to solve challenging scientific and engineering problems. The role involves developing sonar processing algorithms, mathematical models, and software for fiber-optic sensing systems. Requires an MSc in a quantitative discipline, 1-3 years of experience, and strong programming skills.

What you'll do

Execute acoustic modelling and signal processing tasks: Implement and improve algorithms and mathematical models for underwater acoustic sensing systems using principles from signal processing, applied mathematics, statistics, physics, and numerical methods.
Analyze and interpret experimental data: Process and evaluate fiber-optic datasets from laboratory and field trials to extract insights that support design improvements and validation.
Develop and test algorithms: Contribute to the development and testing of algorithms for beamforming, event detection, filtering, and data classification under guidance from senior engineers.
Document and communicate progress: Maintain clear, structured documentation of methods, results, and conclusions. Proactively communicate progress, challenges, and proposed solutions to the team.
Collaborate across functions: Work closely with software, embedded, and hardware engineers to ensure smooth data flow, model integration, and system testing.
Improve team workflows and tools: Identify opportunities to improve data handling, simulation scripts, and processing pipelines, contributing to better team efficiency and clarity.
Share knowledge and provide feedback: Contribute to internal discussions by sharing your learnings, simplifying complex findings for others, and offering constructive feedback on shared work.
