About Us:

At Zealthy, our mission is to make high-quality healthcare accessible to everyone, no matter their location. We are building the world’s largest and most trusted virtual healthcare platform, transforming how care is delivered to ensure anyone, anywhere, can receive the healthcare they need.

Founded by a healthcare entrepreneur with a proven track record, including scaling a previous company to a $5B valuation, Zealthy is positioned for sustainable growth as we rapidly scale to achieve our ambitious vision. Our unwavering commitment to quality and accessibility drives everything we do.

We are a team dedicated to serving our patients. While our in-person work culture runs Monday to Friday and typically extends beyond typical work hours, the true reward lies in the impact we create. Every team member is essential in building something groundbreaking. As a full-time team member, you won’t just shape the future of healthcare—you’ll also share in our success through equity ownership, because we believe that every contributor should be a literal and figurative owner of what we’re creating.

If you are not prepared to fully commit to your role and contribute to the goal of creating the world’s largest and highest quality telemedicine company by working in-person four days a week, please refrain from applying.

Join us and help redefine the future of healthcare.

The Role:

We are actively looking for a full-time Full Stack Developer. Please note that this is a full-time, in-person role based in New York, NY. If you are interested in remote or hybrid opportunities, this position may not be suitable for you.

What You'll Do:

    • You will start as a Full Stack Software Engineer for Zealthy, joining a team of 5 full-time engineers who are currently working at Zealthy and you will also collaborate closely with the Founder / CEO (who oversees product). You will move quickly to iterate on the existing, early product build to make sure the product is ready to scale to users to transform access to high-quality healthcare.
    • You will work in person and participate in daily standup meetings, weekly sprint meetings(or a more fluid Kanban process), and hold yourself accountable to an aggressive product development roadmap.
    • We are an early-stage startup and oftentimes that comes with wearing many hats, which means working across front-end and back-end as well as potentially participating in or leading system architecture or DevOps decision-making.
    • As the organization scales, you will have the opportunity to scale into a leadership role if your performance is strong and you wish to become a leader. This will not need to be decided on Day 1, and will be an evolving conversation between you and the existing leader(s) on the team.

Requirements

    • 1+ year experience in an engineering position at early-stage high-growth startup.
    • It is preferred that you have 1-5 years of experience.
    • It is preferred that you graduated from a top 25 university OR graduated from college with a GPA above 3.7.
    • Experienced in Typescript and able to accommodate a modern tech stack.
    • Relentless resourcefulness and an ownership mindset.
    • Comfortable in a fast-paced environment that requires adaptability.
    • Always learning and curious; open to new ideas and experimentation.
    • Strong work ethic and can do attitude.
    • A desire to be part of a fast-paced startup.

Benefits

  • Time Off: Paid vacation and sick leave, increasing with tenure. Flexible time off handled case-by-case.
  • Holidays: Paid for major US holidays.
  • Equity & Reviews: Equity ownership with regular performance reviews that can impact salary and/or equity.
  • Health: Medical coverage provided. Other benefits to be revisited with plan renewal.
