Chief of Staff to the Founders

ABOUT SENTIS

Sentis is capturing the most accurate state of the human body. We build at the intersection of physical AI and healthcare. We are live in US ICUs, piloting with academic medical centers, and scaling from single units to full-hospital deployments. Our ambition is simple: shaping the future of medicine.

THE ROLE

Sentis is expanding on two fronts at once: across hospitals, from first pilots to multi-unit and multi-site rollouts, and across the business, from hardware and software to clinical research, regulatory, partnerships and capital. You will work directly with our founders, Tim Topper and Christin Seltmann, and help them stay close to the work that matters most across this growing surface.

You will also build the operating and financial backbone Sentis runs on: the models, systems and processes that let a small team scale without losing speed.

WHAT YOU WILL DO

Run meticulous project management. You will hold the threads across dozens of topics, from hospital deployments and IRB processes to investor workstreams and hiring, and make sure nothing falls through the cracks. You coordinate the founders' meetings, draft responses on their behalf and keep every commitment moving.

Shape the strategy. You will work on how Sentis gets from A to B and find the fastest path to each goal. You structure and challenge the founders' thinking, pressure-test plans as an honest broker, and turn ideas into memos, models, decks and plans that move people inside and outside the company.

Extend the founders' execution. You will prepare Tim and Christin for key decisions, from board and investor meetings to hospital partnership negotiations, make sure things happen afterwards, and own strategic workstreams end to end. You lead the special projects that fit no one else's job description.

Build the financial backbone. You construct and maintain the financial model, scenario-plan budget and runway, and work with our external accountants on the monthly close. You keep spend, payroll and treasury under control, so the founders always know where the company stands.

Stand up the company's infrastructure. You set up equity administration, benefits, payroll, corporate policies, compliance and vendor systems. You choose tools pragmatically and replace them when we outgrow them. You own how the company runs day to day, from IT and vendors to the office, with our Executive Assistant handling the daily logistics.

Drive recruiting and people operations. You source candidates, run the process from scheduling to offer and onboarding, and help design the culture and operating cadence of the company as the team grows.

Move hospital deals across the finish line. You support our hospital and partner engagements operationally, from proposals and contracts to security reviews, IRB submissions and procurement workflows, so that a clinical yes becomes a signed and deployed site.

Build and work the network. You know who matters in health AI, digital health and venture, spot the most relevant people early and create strategic connections that open doors for Sentis, from hospital leadership to investors and industry partners.

Represent Sentis and close the loop. When needed, you step in for the founders with hospital partners, investors, regulators and vendors, and you do it with the same bar of care a founder would apply. You bring back what you learn from them and translate it into the decisions and priorities that shape how we run.

WHAT MAKES THIS DIFFERENT

Health AI is one of the defining opportunities of the coming decade. Healthcare is a multi-trillion dollar industry, and whoever builds the data foundation that health AI runs on will shape how that market works for a generation. Sentis is in that race, and we intend to win it.

We are backed by iconic investors (776, Valor Equity Partners, Bling Capital among others) and operators who have built and led at the very top of healthcare and AI, including senior leaders from Merck and from Anthropic, alongside experienced healthcare founders.

Christin has built companies before. She scaled and sold her previous company, holds a Harvard MBA, and brings years at McKinsey and Siemens. Sentis is her third company, and she knows what it takes to go from zero to scale. Tim started as a paramedic, where he experienced firsthand how missing data at the bedside can put a patient's life at risk. That moment became Sentis. He went on to AWS, Columbia and Stanford, and, for good measure, ranks number one worldwide at the Excel World Championship.

This role puts you next to both of them, with a front-row seat across the full breadth of building a company and direct responsibility for turning ideas and decisions into action. The scope is broad, the feedback loops are short and the learning curve is steep. If you want to compress ten years of learning into two, and be part of the team that defines health AI, this is the role.

This is a tour of duty. We ask for a commitment of at least two years, with the explicit prospect of shaping a longer-term role together once we know where you shine.

YOU MIGHT BE A FIT IF

• You have 3+ years in a high-ownership, high-tempo role: in management consulting, or as a Chief of Staff, Founder's Associate or early operator at a venture-backed startup. Exposure to healthcare or health tech is a plus.
• You own projects end to end in ambiguous environments, with minimal structure and minimal supervision. You see problems and fix them yourself rather than wait for someone else, and you stay persistent until they are done.
• You are fluent with numbers. You build financial models in Excel, run scenario analyses and reason from data under time pressure.
• You write and speak at the bar of the most senior people in the room. You draft memos, investor updates and external materials, and you hold your own with clinicians, hospital executives and investors alike. German is a plus, not a requirement.
• You are structured and fast, and you can act with confidence in the founders' stead.
• You are organized to the last detail. The things no one else is tracking are the things you make sure get handled.
• You have range and depth. You can switch context many times a day and still go deep when it counts. One hour you are on an ICU floor or fixing something in the office, the next you are in the room with a hospital executive or a top-tier investor.
• You bring calm and good judgment. You know what matters and what can wait, read people well, and hold them accountable with kindness.
• You are discreet and trustworthy, because you will see everything.
• You have an exceptional work ethic and are comfortable with a demanding role that includes travel to hospital sites and investor meetings across the US.
• You are based in the US and authorized to work here.

HUGE BONUS

• You were on board while a startup went from Seed to Series B or beyond, ideally as one of its first non-engineering hires, and you know firsthand what breaks at each stage.
• You have spent some time as a project manager at McKinsey, BCG, or Bain.
• You have set up finance and people operations systems from scratch.
• You have worked on early-stage fundraising, from the model and data room to investor updates and the process itself.

THE ENVIRONMENT

You will work in person with Tim and Christin in San Francisco and around the globe. We are a small team, and as one of our first hires you will help shape how Sentis works, not just what it does.

COMPENSATION

$120,000 to $165,000 base salary plus meaningful early equity.

NEXT STEPS

We move fast, and we aim to complete our hiring process within two weeks: an intro call, a working session on a real Sentis problem, and a conversation with both founders. If this sounds like your kind of work, we would love to hear from you.
