Job description

Acoustic Engineer

Team: Product Development

Hours: Full Time

Location: Copenhagen, Denmark

Start Date: October 2026 or ASAP

Responsible for acoustic development of product line, ensuring durability, sound quality, and performance in aggressive environments.

Responsibilities

• Select and design acoustic components based on product and market requirements.

• Define initial enclosure concepts.

• Build and evaluate proof‑of‑concept prototypes to validate acoustic concepts.

• Collaborate with Mechanical Engineering during early development to mature acoustic concepts.

• Perform acoustic simulations focusing on sound pressure level (SPL), sound quality, and system efficiency.

• Validate simulation results through physical testing.

• Collaborate with suppliers to refine acoustic components based on simulation and test results.

• Own technical specification of loudspeaker drivers toward suppliers.

• Define driver specifications and tolerances.

• Support manufacturing verification with suppliers.

• Participate in acoustic verification of the final product toward mass production.

• Collaborate with the Audio team on audio signal handling, including crossovers, compressors, and limiters.

Qualifications

• Proven experience designing and simulating loudspeakers, including transducer design and specification, enclosure design, and acoustic measurements.

• BSc or higher in Audio, Acoustics, Mechanical, or a related engineering discipline.

• Experience with loudspeaker simulation and measurements, using both to validate and refine designs.

• Experience with loudspeaker development from concept through verification, and ideally with external manufacturing partners.

• Familiarity with crossover design, FEM simulations, or failure analysis is an advantage.

• Experience building physical speaker mock‑ups or collaborating with large‑scale loudspeaker manufacturing partners is ideal.

• Ability to work independently, take ownership, and collaborate closely with engineers across disciplines.

• Curiosity, creativity, and continuous learning mindset.

• Motivation to contribute to SoundBoks mission and products.
