Brain Training Jobs in California (NOW HIRING)

NextSense is a Google X spinout democratizing access to brain health through proprietary biosensing technology. NextSense recently launched Smartbuds, advanced neurotech disguised as a premium consumer earbud. Using EEG sensors and motion tracking, Smartbuds measure what your brain is doing in real time, then deliver precisely timed, brain-responsive audio to guide it back into rhythm — for deeper sleep, sharper focus, and more genuine relaxation. This is just the beginning. We believe the brain is the next frontier in wellbeing, and that closing the gap between what your brain is doing and what your day demands — in a form factor people already live in — can help them live with more joy, energy, and purpose.

Responsibilities

• Own the near- and long-term product strategy across several retention-critical areas at once, translating ambiguous problems into clear, prioritized decisions

• Take ownership of core retention and engagement KPIs — develop a deep understanding of the user experience and prioritize the highest-leverage improvements to hit ambitious growth goals

• Lead end-to-end product discovery, delivery, and iteration — research, ideation, requirements, prototyping, and testing — partnering closely with engineering, design, data science, and marketing to ship on accelerated timelines

• Design and run a rigorous experimentation program: form explicit hypotheses, structure tests, and turn learnings into a compounding roadmap of wins

• Write clear product requirements and act as the directly responsible individual for execution quality from discovery through launch and post-launch iteration

• Serve as the internal voice of the customer — understand user needs, pain points, and behavior deeply enough to shape product decisions and drive cross-functional alignment

• Anticipate complexity and de-risk long-term initiatives through smart scoping, phasing, and technical foresight, in partnership with engineering

• Partner with marketing, operations, and leadership to align cross-functional initiatives around the retention roadmap

• Bring new core competencies to the team in areas such as onboarding, habit formation, gamification, loyalty, or churn reduction

• Contribute to team best practices and help improve the team's operating cadence

Qualifications

• 5–8+ years of product management experience (or equivalent in growth-related roles), with a track record of shipped products that produced measurable, long-term business impact

• Self-sufficient and highly dependable; comfortable defining problems and driving clarity in fast-moving, loosely defined spaces — small team, CEO-level visibility, no PM org to hide

• Demonstrated ability to build coherent product strategy from ambiguous problem spaces and translate it into phased, executable roadmaps — ideally in areas like onboarding, habit formation, gamification, loyalty, or churn reduction

• Strong analytical and problem-solving skills; highly proficient with product analytics

• Direct experience with consumer subscription or hardware-linked products, digital growth funnels, and running structured experimentation programs at scale

• Fluency building with AI tools (Claude Code, Cursor, or similar) — small team; the tools are the leverage.

Nice to Haves

• Experience with sleep tech, wearables, or other health and wellness products

• Background in consumer electronics product launches, including coordinating hardware and software release cycles

• UX design experience, with an eye for reducing friction in onboarding and everyday use

• App development experience (iOS/Android), enough to work fluently with engineering on technical tradeoffs

• Familiarity with biosensing or other physiological signal data

Why This Role

• Own product for a shipping neuro-wearable and take it from zero to one

• Report to the CEO; "Head of Product" is the trajectory if you earn it

• Equity at a stage where it matters, at a company with a hardware moat + AI for feature development

• In our Labs feature, we can demo your brain on an IBM quantum computer or use Tetris for brain-training. If we can do these things, what can't we do with your insight into what consumers really want?

Location

This is a hybrid position based in Mountain View, CA, requiring at least 3 days per week in the office.

Compensation

$120,000–$150,000 base + meaningful equity.
