About the Role

We are looking for a highly accomplished Generalist Fullstack Engineer for an immediate long-term track opportunity.

What We Avoid

• Profiles with less than 5 years of absolute engineering depth.
• Frequent job hoppers with multiple short stints.
• Developers whose frontend knowledge is restricted to basic styling rather than complete end-to-end logic/state implementation.

Expected Date of Joining Immediate/ 30 days
