Chief Technology Officer

About the role

We reached 12,000+ headphones sold and 100,000+ app downloads without a technology executive. The founders are not engineers, and the next stage of the product needs one at the table.

The mandate fits in one sentence. Own the technology that turns a biometric signal into a frequency that changes how someone feels, and build the engineering organization that ships it at scale.

You join the founding executive team with the CEO and the CMO. The 2027 roadmap is written. The second half of it needs you to exist.

What you will own

• Technical strategy. Set the architecture for app, firmware, cloud, and data through 2028. Decide what we build and what we buy.
• Scale and reliability. Rebuild the sound engine for tens of thousands of concurrent sessions, each layering up to 7 sounds.
• Hardware integration. Own firmware, SDK, and app integration with our hardware partner on the next generation of headphones, including heart rate and HRV sensing.
• The biometric-to-frequency loop. Design and ship the recommendation algorithm: read the listener's state, select or generate the frequency, measure the shift.
• Generative sound. Build the engine that generates frequency and meditation audio on demand.
• Product roadmap. Co-own it with the CMO: activation, retention, and subscription conversion from headphone buyers.
• Engineering leadership. Lead the current engineers and QA, set a weekly release cadence, and hire the next two engineers.
• Technical diligence. Be the technical voice in investor and partner conversations.
• Budget. Own the engineering, AI, and infrastructure spend.

What you will not own

Marketing, paid media, creative, customer support, supply chain, and manufacturing. You are consulted on all of them and responsible for none.

Your first 90 days

What you bring

• 8+ years building and shipping software, with 3+ years leading engineers.
• A consumer mobile app you shipped and scaled, on iOS, Android, or both.
• Real depth in at least one of these: audio and DSP, machine learning and recommendation systems, generative audio, or wearables and biosignals.
• Experience working with hardware and firmware teams, or proof you learn a new domain in weeks.
• The ability to explain a technical tradeoff to non-technical founders in two minutes.
• A daily AI-assisted workflow. You ship faster because of it and can show how.
• Comfort being the only technical executive in the room.

Nice to have

• Generative music or audio ML in production.
• PPG, HRV, or other biosignal processing.
• Bluetooth Low Energy and embedded firmware.
• A startup you helped take from early traction to scale.
• Experience on the technical side of a fundraise or acquisition.

What we offer

• A founding executive seat with founding equity.
• A team from day one: senior engineer, platform engineer, QA engineer, design, and a hardware partner.
• An engineering budget you control.
• Advisors who have spent their careers in audio hardware.
• Work from anywhere, with Los Angeles for the moments that matter.
• A room at the Creator House in LA whenever you want it. Optional.

How to apply

• Your LinkedIn or resume.
• One thing you built that you are proud of, with a link.
• Three or four sentences on which part of the mandate you would attack first and why.
