What you will do:

1. Create cross-browser, fully functional web pages using HTML5, CSS3, and JavaScript, while strictly adhering to accessibility and W3C web standards.
2. Collaborate with developers, product managers, designers, web publishers, producers and back-end engineers to support revenue operations and meet project deadlines.
3. Review new code (self and peer) following W3C web standards and strict QA guidelines.
4. Evaluate technical feasibility and offer suggestions & guidance for product development. Build proof-of-concept prototypes for new projects.
5. Create scoping timelines and development project plans for new projects.
6. Participate in interviewing, hiring, on-boarding, and training new employees.
