What are the responsibilities and job description for the Marketing Lead position at Proper Voltage?
Please note that we are unable to provide visa sponsorship for this position.
About Us
At Proper Voltage we are unlocking the next generation of battery technology across robotics, data centers, and defense.
We're building intelligent battery systems that make advanced chemistries (sodium-ion, lithium-titanate, lithium-silicon) work in products that were never designed for them. Humanoid robots can upgrade power systems without redesigning their entire platform. Data centers get safer, cheaper backup power. Drones and autonomous vehicles get higher energy density without lengthy integration cycles.
If you want to work on hard engineering problems that matter, this is the place for you.
Job Overview
This role is built for someone hungry, talented, and at a point in their career that they are still excited by the opportunity to build a marketing function from the ground up and has enough experience to ship excellent work without hand-holding.
You will work directly with our CEO, COO, and head of sales to establish strategy and positioning. You will own execution across the entire marketing surface: brand, content, website, events, demand generation, sales enablement, and external partner management. You will be the only marketer on day one, and you will hire a small team underneath you as we grow.
This is a high-trust, high-autonomy job for someone who wants to operate two levels above their resume. The right person sees this as the role that defines the next phase of their career.

This role will be a great fit for someone who lives these every day.

What You'll Do
First 90 days
- Help shape and then own the day-to-day execution of our market positioning, translating company strategy into messaging, content, and assets that move buyers.
- Lead in-house quarterbacking of our flagship commercial product launch, including managing the external production firm running the event, the PR partner, and the press and analyst activation around it.
- Build the launch-grade version of our website, sales collateral, datasheets, and customer-facing brand assets.
- Stand up the marketing technology stack and the first version of our demand generation motion.
- Source, vet, and manage external partners on defined-scope projects (event production, video, design, PR) and run them tightly to schedule and budget.
- Own and operate the full marketing surface: brand, content, web, events, demand generation, sales enablement, and channel marketing.
- Drive qualified pipeline against revenue targets through paid, ABM, content, and field marketing.
- Build the cadence of customer stories, case studies, and reference programs that turn early wins into sales leverage.
- Establish our presence at the events that matter on both sides of our business: data center events such as DCD Connect, Data Center World, and 7x24 Exchange; energy storage events such as RE ; and robotics events such as Automate and Humanoids Summit.
- Hire one or two marketers underneath you (likely a content and creative generalist and a demand generation specialist) as the function grows.
- Three to six years in B2B marketing, ideally at a strong early-stage or Series A or B company where you were one of the first marketing hires and reported to a senior leader you learned a lot from.
- Real range. You have personally written copy that converted, run campaigns that hit numbers, edited a website launch, briefed a podcast or press contact, managed an agency, and produced an event. You do not need a specialist for everything because you have done a lot of it yourself.
- Genuine curiosity about technical products. You do not need to be an engineer, but you find power systems, batteries, robotics, and data center infrastructure interesting, and you will read everything you can find about them in your first 30 days.
- High output. You move fast, ship a lot, and do not need a long ramp before you are producing real work. References will describe you as one of the highest-output people they have worked with.
- Excellent writer. Most of your job is going to be turning technical reality into language that buyers and the market understand. If you cannot write well, you cannot do this job.
- Coachable. This is a role for someone who wants to take direction from a CEO and a head of sales who will be deeply involved in marketing strategy. The job is to take strong inputs and turn them into excellent execution, not to operate fully independently.
- Carries a network you will actually use: designers, freelancers, podcast hosts, newsletter operators, peers at adjacent startups, agency contacts. The kind of network you can put to work in your first month.
- Came from a deep-tech, hardware, defense, robotics, energy, or AI infrastructure company where you marketed a technical product to a technical audience.
- Was the #2 or #3 marketer at a company that meaningfully grew during your time there, and you can speak specifically to what you owned and what moved as a result.
- Comfortable around founders. You can hold your own in a room with the CEO, push back when something is wrong, and translate strategic intent into work that ships.
- Has run an event with a real production component, such as a launch, a customer summit, or a conference activation, and knows what good external production looks like.
This role will be a great fit for someone who lives these every day.
- Customer needs at the core. We start with the customer and work backwards.
- Extraordinary as standard. We expect extraordinary results from ourselves and each other.
- High-energy collaboration. Our best ideas are inspired by working together.
- Empowered ownership. Every member of our team takes ownership of their work.
- Strength through scrappiness. We use resourcefulness and resilience to overcome challenges.
- Base salary in the range of $120,000 to $160,000, depending on experience.
- Annual performance bonus targeted at 10 to 15 percent of base, tied to pipeline and launch execution.
- Series A equity grant in the range of 0.15 to 0.35 percent, with the top of the range reserved for exceptional candidates.
- Comprehensive medical, dental, and vision coverage.
- 401(k) program.
- Hybrid schedule based out of our Carlsbad, California headquarters.
- Relocation support available for the right candidate.
Salary : $120,000 - $160,000
