Mechanical Engineer

Omnisent is pioneering scalable acoustic sensing powered by AI — transforming audio into real-time intelligence.

We build hardware + software tailored for acoustic data, designed to extract insights from complex acoustic signals. Our proprietary ultra-low-power sonic devices capture and process acoustic signals in real-time, training what we call a Large Acoustic Model (LAM) — our foundation model built to decode the rich, messy, and untapped world of non-speech audio.

We’re starting with the manufacturing industry, applying our tech to compressed air systems — one of the most overlooked sources of energy waste. From there, we’re expanding into energy, defense, space, and smart cities — sectors where sound is the next frontier.

Tasks

Mechanical Design & Prototyping

• Design, make, and test an innovative sensor at the heart of our acoustic platform, in close collaboration with the technical lead.
• Perform dynamics and vibrations calculations and use FEA methods to simulate acoustic and mechanical responses.
• Design microphone arrays to characterize physical parameters of various geometries and environments.
• Develop test setups to characterize acoustic transmission through different materials (e.g., air, walls, machinery).
• Prototype an enclosure for an IoT sensor using additive methods like FDM, SLS, SLA.
• Select materials and fastening methods for tool-less assembly in harsh environments with vibrational loads and EM noise.

Device Integration

• Collaborate with electronic, mechatronics and signal processing engineers to ensure proper mechanical integration of acoustic devices and PCBs and accessories.
• Iterate and enable the physical systems to adapt seemlessly to changing real-world requirements to develop ground-breaking technology.

Certification & Documentation:

• Prepare hardware for environmental and regulatory certifications, including IP (e.g., IP67/IP68), CE marking, and mechanical stress testing (vibration, shock, temperature cycling)
• Document designs and key learnings throughout the development lifecycle, building our collective knowledge base.

Cross-Functional Collaboration:

• Work closely with firmware, hardware, and AI teams to ensure tight integration between mechanical, electrical, and software components.
• Support prototype development, functional testing, and iterative field deployment at our ongoing pilots in-field.
• Assist in coordinating research collaborations with test labs and well-renowned institutes to translate findings into the mechanical systems of our sensor.
• Contribute to developing best practices and design documentation, ensuring that knowledge is continuously shared among teams
