Senior Drupal Developer needed

We are looking for a Senior Drupal 7/8/9 Developer for 15-30 hours of help per week in an ongoing basis. We are consulting/development agency that helps enterprise organizations to better understand their problems and identify opportunities where Open Source technologies can be utilized to solve these problems. In order to do so, we collaborate with our clients on requirements and estimates to create a project plan and we then provide development talent for the project. Progress is managed by a proprietary methodology that helps us reach our goals while staying within our clients' budgets. DUTIES AND RESPONSIBILITIES: As an agency, we are currently involved in several large projects which require a variety of skills. In order of importance, they are Drupal 7, Drupal 8/9, and finally general PHP, ideally also with experience in Node.js/React/MongoDB. As a full-stack senior developer, you will be working on both backend site-building and frontend theming. You will be working on several projects and should be open to learning new technologies or improving your current skills when other needs arise. In order to complete your tasks, you will be working within the client’s proprietary methodology. As a developer, you will need to be compatible with 3 major aspects of this methodology: 1) You would be dealing with JIRA tickets estimated at a maximum of 2-3 hours at a very granular level. For each one of them, you would be provided with the user story, technical approach, and acceptance criteria. 2) Tasks are sometimes estimated by another internal team member, so you would need to: Communicate if you disagree with the estimate and offer suggestions or alternatives to make things happen within budget, while explaining trade-offs required to achieve the deadline, even if that involves offering implementation modifications to your project manager or the client. 3) Track your time by using Toggl, which allows the company to collect metrics around time spent on work, and properly invoice the client. RELATIONSHIPS - WHO YOU'LL BE WORKING WITH: You will be reporting to the agency Principal who is also a senior software engineer and communicating using Slack and email. START DATE: As soon as possible. EXPECTED CONTRACT DURATION: We have a number of large Drupal 7 to 8/9 migrations that we need to implement ASAP and which will last for 5-6 months.
