We are looking for candidates with extremely strong programming skills and rich experience in React Native. A typical day at work would start with discussions with product managers about requirements. The candidate is expected to understand these requirements, use his/her logical reasoning to determine the gaps in the requirements discussed, determine the fastest approach to deliver the output, and implement the solution in a timely manner – all this while maintaining the quality of the output with at least 90-95% completeness and accuracy. You are responsible for the software that you develop and hence, unit/system testing is part of your job.
Candidate Profile:
Our requirement is extremely specific, and we are very particular about the candidate we are looking for. The selected candidate would be a street-smart individual with a focus on the completion of tasks at hand. We are NOT looking for candidates who require hand-holding at every stage. The candidate is expected to be enterprising enough to read between the lines (of the requirements) and deliver them in a ‘deployable’ state. We do not have the liberty to document every requirement and provide the same to the developers. Hence, as mentioned above, the requirements would be provided swiftly and only through conversations.
If you believe you fit the role well and would like to grow in a great work environment, we would like to talk to you!
