Description

Syneos Health® is a leading fully integrated biopharmaceutical solutions organization built to accelerate customer success. We translate unique clinical, medical affairs and commercial insights into outcomes to address modern market realities.

Our Clinical Development model brings the customer and the patient to the center of everything that we do. We are continuously looking for ways to simplify and streamline our work to not only make Syneos Health easier to work with, but to make us easier to work for.

Whether you join us in a Functional Service Provider partnership or a Full-Service environment, you’ll collaborate with passionate problem solvers, innovating as a team to help our customers achieve their goals. We are agile and driven to accelerate the delivery of therapies, because we are passionate to change lives.

• We are passionate about developing our people, through career development and progression; supportive and engaged line management; technical and therapeutic area training; peer recognition and total rewards program.
• We are committed to our Total Self culture – where you can authentically be yourself. Our Total Self culture is what unites us globally, and we are dedicated to taking care of our people.
• We are continuously building the company we all want to work for and our customers want to work with. Why? Because when we bring together diversity of thoughts, backgrounds, cultures, and perspectives – we’re able to create a place where everyone feels like they belong.

Job Responsibilities

• Develop regulatory documents for submission to regulatory agencies globally including Clinical Study Reports, Clinical Summaries of Efficacy and Safety, and Clinical Overviews, in accordance with ICH and other global guidelines, standards and processes, and Incyte authoring standards, as applicable, in adherence with study/project timelines and corporate objectives.
• Manage medical writing projects, including developing timelines (working with the study/project teams, as necessary) and communication with cross‑functional team members to maintain awareness of review cycles and expectations.
• Participate in cross‑functional meetings to provide input regarding medical writing deliverables, timelines, and any process(es) needed for the completion of regulatory documents.
• Review other documents associated with the assigned project(s) (eg, Protocols and Statistical Analysis Plans), as appropriate.
• eCTD submission experience preferred.
• We don’t need this person to mentor junior writers, manage external vendors, or participate in the standard operational procedures or other department initiatives. And I don’t have a preference for the EU versus US. We have writers located on both sides and work globally as a team.
