Founders Factory builds and funds startups together with exceptional entrepreneurs and the world's leading companies. Headquartered in London and operating globally, Founders Factory backs visionary founders with capital, dedicated support from a team of expert operators, and unrivalled access to a coalition of industry leading corporate partners.

We are looking for a Venture Builder who is passionate about building the future of occupational safety.
Climate change is no longer a background risk for the people who work outdoors or underground — it's an active occupational hazard. Miners and construction workers are increasingly exposed to extreme heat and degraded air quality, driving up rates of heat stress and pulmonary disease.
You’ll be working on our new venture: a medical-grade wearable device paired with a real-time data dashboard, designed to monitor at-risk profiles among miners and construction workers, flag early signs of heat stress and respiratory strain, and give employers the visibility they need to intervene before a health incident becomes a fatality.
As a Venture Builder, you specialise in taking ideas from zero to venture-backable businesses. You work closely with founders to shape strategy, validate problem spaces, build MVPs, and find early product market fit. This is a hands on, high ownership role. You'll operate across product, design, growth and tech, moving fast, making decisions, and focusing relentlessly on what creates the most leverage at each stage of a venture. You have a varied skill set and will have demonstrated an interest in tech and entrepreneurship. You will be an advocate for FF's values and mission and be committed to supporting founders. You are opinionated but evidence led, creative but commercial, and comfortable operating in ambiguity. You care deeply about building products people actually want and businesses that can scale.
Please note that we are looking for Venture Builders who are available for an initial 6 month contract (freelance). Our preferred location is London.
Owning the end-to-end early build: from problem definition and MVP scoping through to shipping, testing, and iteration
Getting products into users' hands fast, using lean, experimental approaches to validate assumptions and generate learning
Shaping the customer experience and product vision, balancing user needs with commercial and technical realities
Working closely with founders to challenge thinking, sharpen focus, and drive momentum, especially when things feel unclear or uncomfortable
Helping ventures progress through studio stage gates, supporting founders towards strong, evidence-backed IC decisions
Spotting opportunities early by staying close to market dynamics, emerging tech, and real user behaviour
Communicating clearly and regularly, sharing progress, learnings, trade-offs, and recommendations with founders and the wider studio
You’re coming from a background in digital health, medicine or wearables
You think in systems, not just devices: you can connect a sensor on someone's body to a dashboard an employer actually checks, and you understand what "real-time" needs to mean when the risk is heatstroke, not a missed notification
You've been through a regulatory clearance or licensing process for a health or safety product and know that compliance isn't a box to tick at the end — it shapes the product from day one
Driving momentum by subscribing to lean methodologies and an experimental approach, you prioritise speed, learning, and focus over perfection
Comfortable wearing multiple hats (product, design, tech, growth) and knowing when to pull in specialist support
Strong technical mindset, with the ability to build no-code / low-code solutions, prototypes, or proofs of concept to accelerate validation
Commercially curious with the ability to think about ICPs, value propositions, pricing hypotheses, and early GTM alongside product
Bonus if you have research or clinical exposure to pulmonary disease or occupational safety
Thrive in ambiguity and enjoy solving messy problems
Quick thinking and intuition, someone who can balance creativity with objective data
A passion for creating products people love, caring about product performance is key
The ability to adapt and operate in an ambiguous environment
Comfortable with taking calculated risks and learning fast
Wanting to continuously improve your skills and productivity, challenging yourself when you can
Strong leadership that drives outcomes
Being approachable and optimistic
