About the job

SummaryBy Outscal

Experienced front-end developer with expertise in ES6, Vue.js, and pub/sub architecture to join a talented team working on BMWUSA.com. Strong communication and collaboration skills are essential, as well as experience with responsive design, web performance optimization, and WCAG accessibility.

The Critical Mass technology team is looking for an inspired, motivated, and experienced web developer to join our team. We are an experience design agency with a focus on the customer, which means that multi-discipline collaboration and prototyping are at the heart of our process. This role will join a talented team working on BMWUSA.com. We're using the latest technologies including ES6, pub/sub architecture, and a clean component-based approach to deliver reusable, innovative, and responsive experiences. Web performance & accessibility are also key concerns because of their respective importance to user experience and perception of a premium experience. 

Our team culture thrives on a balance of collaboration and focused time, which means you won't be spending your days turning Figma files into HTML or simply pulling tickets off a JIRA queue - rather you'll be part of the design and prototyping process using data and user research feedback as input. You'll help balance the team between innovation and pragmatism. Additionally, the team has several remote members so we use screenshares and Slack as to keep communication flowing. We have a lot of fun and hope you'll join us.

Our new hires & employees are the future of our organization, and we want to set you up for long-term success. In an effort to do so, we expect our team to work from an office a minimum of 3 days a week.


You will: 

  • Collaborate with Design and UX to prototype user interactions 
  • Mentor other front-end developers 
  • Ensure compatibility of code across devices and viewport sizes 
  • Assess and optimize page performance and WCAG compliance 
  • Work with delivery team to ensure overall quality of the experience and support this with tests and documentation.

You have: 

  • Advanced English Proficiency (B2+ reading, writing, and conversation)
  • Strong communication skills with a team-centric approach to discussion and decision making within a distributed team. 
  • Expertise in JavaScript - specifically ES6, Vue.js, pub/sub architecture, and REST APIs. 
  • Experience using HTML5 semantic markup, CSS3, and CSS & SVG-based animation on responsive consumer-facing websites. 
  • Full command of Git, the terminal, continuous deployment and integration, and other modern fundamentals. 
  • Strong troubleshooting ability and technical analysis skills - web performance optimization included. 
  • WCAG accessibility experience. 

You may have: 

  • Experience developing within CMS platforms, preferably Adobe Experience Manager 6.4 or newer. 
  • Experience with performance optimization techniques 
  • Experience using and configuring build automation tools (Vite, npm, etc.) 
  • Agency experience.

What We Offer:

  • Competitive benefits packages
  • Vacation, compassionate leave, sick days, and flex days
  • Access to online services for families and new parents
  • End-of-year closure days (not deducted from vacation balance)
  • Diversity and Inclusion Board with 12 affinity groups
  • Internal learning and development program.
  • And more…
