Custodian

Retro develops therapies for diseases driven by the biology of aging. We focus on cellular reprogramming and autophagy to rejuvenate cell and tissue function with the ultimate aim of adding 10 years to healthy human lifespan.

We’re building a mission-driven team of accomplished and kind individuals who embrace our startup culture of rapid iteration, transparency, and versatility.

We are hiring a Custodian whose primary focus will be keeping our facility clean and in order. You will be a part of the Science Operations team- a close-knit group of dedicated, resourceful humans, handling all things labs, facilities, and logistics.

You’re a hands‑on caretaker who treats the building like your home – stepping in to keep every corner welcoming and functional. Meticulous and resourceful, you follow routines, tackle minor issues before they grow, and pivot effortlessly as needs shift. You have a “find it, fix it” mentality and are always willing to jump in and help where needed, even without being asked.

• Clean office spaces and common areas – vacuuming, mopping, trash collection, wiping down surfaces, and more.
• Maintain spotless restrooms and kitchenettes across both buildings.
• Assist with inventory, stocking, and ordering supplies.
• Proactively identify upkeep needs (spills, scuffs, clutter) and tackle them without waiting for direction.
• Assemble furniture, mount fixtures, and handle basic workspace reconfigurations (including the occasional event setup).
• Partner on team projects that improve facility functionality and organization.
• Provide occasional weekend or holiday coverage, with opportunities for overtime as needs arise.

• Aren’t intimidated by getting dirty and cleaning things you have never cleaned before.
• Enjoy variety and wearing multiple hats, switching between cleaning, stocking, and simple upkeep duties.
• Are detail‑oriented and organized and take pride in keeping work spaces, surfaces, and supply closets in top shape.
• Adapt quickly to changing needs and priorities, staying flexible in Retro’s dynamic environment.
• Have the physical stamina to lift up to 50 lbs, climb ladders safely, and move around the facility with ease.
• Are comfortable using basic digital tools for simple inventory tracking and supply requests.
• Show a “find it, fix it” mindset, proactively spotting and addressing small issues to improve our labs and offices.

Hourly compensation is $28–$31 per hour. Total compensation also includes generous equity and other benefits such as:

• Medical, dental, and vision insurance for you and your family.
• 401(k) plan with 4% matching.
• Unlimited time off and 10 company holidays per year.
• Annual learning & development stipend.
• Free lunch and snacks.

We take pride in cultivating an environment that fosters collaboration, open communication, and authenticity. We believe that great results are best delivered by a highly creative team working in concert. We are an equal opportunity employer; we do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. We are diverse in background and singular in mission.
