Senior Frontend Developer

We're looking for a Senior Frontend Developer to join our Product Department - the ~20-person crew behind Sol

Develo's apps for the Atlassian Marketplace and monday.com Marketplace. Think Worklogs, QAlity, and Checklists: tools relied on by everyone from small teams to huge, well-known corporations to run their Jira workflows. We build what our users actually ask for - closely listening to their feedback and shipping the features that matter to them, so what you build gets used, fast.

You'll join one of our two Scrum teams (each with 3-4 developers, a tester, a product owner, and a UI/UX specialist), each owning a set of products. You'll also lend your frontend expertise across teams when they need it - this is a role for someone who's happy being the frontend go-to person, not just a team member.
