Job Title

Senior Administrative Assistant

Who We Are

Jennison Associates is a global investment management firm with over $200 billion in Assets under Management spanning across a range of various equity and fixed income investment strategies. Jennison was founded in 1969 on the principle that doing what’s best for clients will always be right for the business. Grounded in our firm values of integrity, collaboration and client focus, the mission across all areas of our firm is to deliver superior long-term investment returns and excellence in client service. This singular focus is embedded in our culture and reflected in the way we invest, the service we provide to our clients, and the people we hire. We recognize that each employee plays a key part in achieving our mission, regardless of their role or title. As a result, we continually strive to make Jennison a fulfilling and rewarding place to work for all employees.

Our Function

The Senior Administrative Assistant (Admin) is a mission-critical partner to our Healthcare Team, acting as a Research Assistant, delivering proactive support and seamless organization to a team of Managing Directors operating at the highest level of pace, complexity, and connectivity within our firm. This role is distinct from other Administrative support roles at Jennison given this Admin will be supporting the only hedge fund team in the firm and is the only Admin role supporting a single sector (Healthcare). One of the key requirements is building relationships with external as well as internal stakeholders.  This role requires an individual skilled in building relationships, maintaining team cohesion, and driving operational excellence almost entirely via Microsoft Teams, email and phone calls.

Your Impact

Your responsibilities will include but are not limited to the following:

  • Serve as the organizational and communications hub for the healthcare team of four investment professionals, acting as a liaison to sales counterparts—including Healthcare Specialty Sales and Sales teams at various investment banks—by proactively building virtual relationships and staying ahead of evolving priorities.
  • Own all travel bookings (domestic/international), with an understanding that each team member has different preferences, so customized planning for each individual is imperative.
  • Maintain an ongoing end-of-day (EOD) summary that serves as a workflow document compiling all outstanding travel, RSVPs, and scheduling questions in a single concise communication, reducing inbox overflow and allowing the team to respond to non-urgent questions after market hours. 
  • Utilize Microsoft Teams for rapid communication—quick check-ins and approvals (such as travel screenshots/questions) are handled via Teams chat only, ensuring efficiency and responsiveness in a virtual work environment.
  • Monitor, track, and add all sector events (including conference calls, bus tours, symposiums, conferences, medical meetings, quarterly earnings, analyst and company road shows, (in person and virtual) etc.) to our shared calendars and keep the team apprised of new events that are released (there are multiple new events released daily) so they can divide and conquer. 
  • Minimize training requirements by demonstrating high autonomy—seek out information, ask questions, use the detailed “how to” documents to learn how to do many parts of the job. 
  • Learn to anticipate needs, and adapt quickly with limited direction, understanding that you are joining a busy and dynamic team.
  • Act as the bridge and “eyes and ears” for the team: proactively manage systemic communication with external contacts and internal stakeholders.
  • Arrange and coordinate both on-site and virtual meetings, ensuring pre-meeting materials are prepared and distributed ahead of time and all guests are registered with security (using an internal system) and ZOOM is set up.
  • Ensure that individual and team calendars are accurate and updated, with a keen eye on optimizing the team’s time and providing all relevant information for the event in the invite (most up to date agenda, ZOOM link, confirmation code, meeting addresses, etc.)
  • Handle expense management (via Concur) with accuracy and timeliness.
  • Assist with email monitoring and responses to help Portfolio Managers focus on their core responsibilities

Your Required Skills

Your required skills must include:

  • 5-10 years’ experience in an administrative assistant capacity
  • Experience at an Asset Management firm or in Financial Services Industry
  • Interested in healthcare investments and relationship building across the sell side (investment banking, sales & trading and research)
  • Proven success as a proactive self-starter in remote or virtual-first roles, with a demonstrated ability to build and manage relationships entirely via Teams/email/phone.
  • Exceptional verbal and written communication skills, with an emphasis on clarity, brevity, and professionalism in virtual environments.
  • Advanced fluency with Microsoft Teams, Outlook, Concur, and online travel booking platforms.
  • Familiarity with common AI concepts as well as ability to leverage AI tools and platforms (e.g., Perplexity, Copilot) to improve productivity, automate tasks or enhance decision-making
  • High adaptability, organizational prowess, and ability to tailor communication and support to different personalities and work styles within the team.
  • Ability to handle sensitive or confidential information with discretion.
  • Confronts each assignment with a sense of urgency, ownership and strong attention to detail
  • Team player; possesses a high level of interpersonal skills
  • Forward thinker: anticipates issues and pro-actively makes recommendations and changes
  • Receptive to real-time constructive feedback and able to adapt to current needs
