Junior Fullstack Developer, HubSpot CMS (all genders)

About the Role

You'll join our Lisbon engineering hub as a Junior Fullstack Developer focused on HubSpot CMS. Day to day, you'll deliver tickets across custom modules, HubL templates, serverless functions, and QA fixes for our enterprise client websites.

The work is real client work, not warm-up tickets, and you'll be paired with senior engineers from day one. The bar at 12 months is independent ticket delivery across 5+ client projects with a bug-reopen rate below 5%.

This is the first foundation hire of our Lisbon engineering hub, which will scale over the next two years.

A note on platforms. We deliver on HubSpot CMS, but at Junior level we hire for component-driven CMS thinking and learning velocity, not platform-specific tenure. If your experience is on Webflow, Contentful, Sitecore, Storyblok, Sanity, or Strapi (professionally, in a bootcamp, or in a personal project) and you're excited to ramp into HubSpot CMS in your first 3 months, we want to talk to you.

We fund the HubSpot CMS for Marketers and CMS for Developers I certifications and pair you with senior HubSpot engineers from day one.

What You'll Do

• You'll onboard into our HubSpot CMS workflow within 3 months and start delivering reviewed PRs independently

• You'll ship your first custom module or feature to a live client HubSpot environment within 3 months

• You'll deliver 40+ merged tickets across custom modules, HubL templates, and small serverless functions on live client projects within 12 months

• You'll keep your bug-reopen rate below 5% on your own deliverables, tracked in Jira

• You'll contribute at least 3 reusable components to our internal HubSpot CMS module library

• You'll pair reliably with senior engineers and participate in code reviews at a level that improves your own output month over month

• You'll handle first-line async communication with Managed Services PMs in English

• Exposure to multiple component-driven CMS platforms

• Experience with HubSpot serverless functions, REST APIs, or webhook handling
