About us:
Web Summit brings together founders, investors, speakers, partners and attendees at technology events around the world. We're headquartered in Dublin, with engineering teams in Dublin, Lisbon and throughout Europe.
We build our own software because tightly integrated software lets us run the best events in the world. Our software helps attendees prepare, find relevant people and activities, and make connections.
What you'll achieve
Build and improve the web app attendees use before and during our events, working closely with Product and Design.
Ship small improvements often, working end to end, and use what you learn to shape what comes next.
Keep the app fast and reliable with tens of thousands of people on it at once, and safe to change while an event is running.
Help engineers grow through clear expectations, useful feedback, pairing and opportunities to take on responsibility.
Work on site at events, watch people use what you've built, and bring that back into the product.
Who you are
You care how it feels to use, not just how it's built.
You measure your work by what people do differently, not by what shipped.
You enjoy finding the version of an idea that needs less software.
You'd rather find out this week than be sure next quarter.
You explain your decisions clearly and make it easy for colleagues to question them.
You've built something small that people ended up using for things you never planned.
You share what you know.
What we're looking for
Strong Ruby on Rails and PostgreSQL experience. You're happy with server-rendered views and JavaScript where it earns its place.
Experience shipping and improving customer-facing software in small, useful increments.
Experience growing a product from a small set of building blocks, and keeping them small as the product grows.
Experience making production changes safe through appropriate tests, monitoring, staged rollout and recovery plans.
Demonstrated skill in developing engineers: setting clear expectations, giving useful feedback, delegating responsibility and addressing performance concerns fairly.
