Jellyfish is looking for a creative, detail-obsessed, and results-driven Web Developer. You’re passionate about building beautiful, functional digital experiences that help internal teams, prospects, and customers engage with a world-class Software Engineering Intelligence platform. You’ll help bring our story to life across our website, campaigns, and interactive experiences – making complex ideas intuitive and impactful.
We need a humble, hungry, and people-smart team player who will thrive in a fast-moving, high-growth environment – someone who cares deeply about user experience, sweats the technical details and brings bold ideas. You’ll play a pivotal role in how Jellyfish shows up.
You’ll report to our Creative Director and work closely with stakeholders across design, product marketing, content, and growth teams. You’ll take ownership of our web infrastructure and user experience and help us scale how we communicate value through our digital presence.

Let’s talk about us!
This is all about you, but you want to know a little about us.

With the help of our customers, we have built the first Engineering Management Platform, providing visibility into engineering organizations, their work, and how they operate. We enable leaders to align engineering decisions with business initiatives and deliver the right software efficiently and on time.
