We are seeking a technically curious, resourceful, and highly motivated web developer to join our team and help build, maintain, and optimize Pacagen’s digital experience across all web properties.

As a part of our team, you will have the opportunity to directly impact the online presence of a rapidly growing consumer biotechnology brand. You will support ongoing development of Pacagen’s website, landing pages, and digital funnels to ensure seamless user experience.

Why work with us?

We’re a fast-paced startup that is delivering life-changing consumer products powered through cutting-edge biotechnology. We have a relentless team that works hard to make sure that we can get those products into the hands of the people that need them most. Working at Pacagen will be an exciting growth opportunity for your career as you’ll get exposure to world-class partners, mentors, and innovative people from every field.

Why NOT work with us?

You’ll notice that the phrase “fast-paced” is in this job description multiple times. Building an amazing, profitable company in a few years is not easy and we aren’t here to pretend like it is (believe us, we’ve done this before). Startups are stressful and not made for everyone, but on the flip-side extremely rewarding. The best performers get a career boost more drastic than anything they could imagine, but not everyone is fit for the job.
