We bring together physics, AI, and simulation to give teams the synthetic data and development tools to design devices, develop algorithms, and train and evaluate AI systems at scale. From wearables and voice AI to physical AI, world models, and multimodal foundation models, our ambition is to shape how intelligent systems hear, understand, and interact with the world. Our customers include some of the world's leading companies in AI and consumer electronics, putting our technology at the heart of ambitious developments in audio and intelligent devices.\nFounded in 2020, Treble is growing rapidly. With strong funding, deep scientific roots, and an exceptional international team, we are expanding our presence in the US and building technology with global reach. Joining now means helping shape both our platform and its adoption by teams working at the frontier of AI.\nAs we continue to grow, we are looking for a Senior R&D Engineer to join our Core Technology team and develop advanced acoustic simulation capabilities for audio devices.\nAbout the role\nYou will help extend Treble's ability to model how audio devices emit, receive and interact with sound. Working with our simulation and software teams, you will develop numerical methods and production software for device-scale acoustics, and connect these capabilities to the wider simulation platform. There is also scope to improve the geometry processing and meshing workflows used to prepare CAD models for simulation.\nThe role covers the path from physical formulation and numerical implementation to verification, validation and reliable use in a product. You will bring deep expertise in audio device simulation and experience turning numerical methods into reliable software. You will help identify the level of modelling detail needed for useful, accurate results at practical computational cost.\nYour tasks include\nDevelop and implement numerical methods for acoustic device modelling, including finite element formulations\nExtend device models with vibroacoustic or other coupled effects where these are important for accurate results\nDevelop appropriate source models, boundary conditions and material representations for priority device applications\nHelp improve CAD model preparation and meshing workflows, working with software engineers on geometry quality and simulation requirements\nVerify implementations against analytical solutions and numerical benchmarks, and validate models against measurements\nImprove solver accuracy, robustness and computational efficiency across relevant device configurations\nIntegrate new methods into maintainable production software with clear tests, documentation and examples\nWork with Product, Applications and customers to identify valuable capabilities and demonstrate their practical impact\nThe specific areas you work on will depend on product priorities and customer needs.\nWhat we are looking for\nSubstantial industry experience developing acoustic simulation software or solver capabilities for audio devices\nDeep expertise in modelling microphones, transducers, wearables, hearing devices or comparable audio systems, grounded in practical work with these devices\nDeep knowledge of computational acoustics and finite element methods, including numerical linear algebra, discretisation, convergence and sources of modelling error\nStrong programming skills and experience implementing, testing and maintaining scientific computing software\nA rigorous approach to verification and validation, including comparison with measurements or established reference solutions\nA track record of turning simulation methods into robust, maintainable software used by engineers in device development\nAn ability to turn research into practical capabilities and collaborate across scientific and software engineering disciplines\nProficiency in using AI tools to improve the quality and efficiency of your work, and an interest in exploring and shaping AI-powered workflows in your field\nNice to have\nAn MSc or PhD in acoustics, computational physics, engineering or a related field\nExperience with thermoviscous acoustics, porous materials, narrow passages or electroacoustic coupling\nExperience coupling device-scale models with larger acoustic environments or computing directional device responses\nExperience with high-performance computing, parallel solvers or production C++ and Python workflows\nExperience with computational geometry, CAD processing or mesh generation, including geometry repair and simplification for numerical simulation\nKnowledge of geometrical acoustics and hybrid acoustic simulation methods\nIf you have built simulation capabilities for audio devices and enjoy turning deep technical expertise into tools engineers can rely on, we would love to hear from you. You do not need to match every nice-to-have to apply.\nWhat we offer\nCompetitive compensation, including stock options and the opportunity to share in Treble's growth\nChallenging work at the intersection of physics, simulation and AI, with direct impact on customers' products and commercial success\nCollaboration with leading AI and consumer technology companies building next-generation devices and intelligent systems\nA key role in extending Treble's core simulation technology, with direct influence on the capabilities available to device developers\nA highly flexible, family-friendly work environment built on trust, ownership and autonomy\nAn ambitious, collaborative international team with deep expertise in acoustics, simulation and audio technology\nCompetitive benefits\nLocation\nTreble HQ in Reykjavik, Iceland, or remote.\nDeadline for application\nOctober 15th 2026.
