Our core values serve as the guiding principles that define our desired culture, direct our behavior, and shape how we work together and with clients. Alignment with our core values is a key consideration in hiring and performance reviews.

Community – We contribute to the growth of our agency, our industry and our communities. Accountability – We show up, keep our word, and take ownership of our work and results.

Our Hiring Process

Our hiring process is designed to help us get to know you and give you a genuine feel for our culture and team. It typically includes short conversations with our recruiting team and hiring manager, a team and / or leader interview, and final selection.

To support fairness and consistency, we use AI tools to assist with parts of the process. Résumés may be reviewed initially with an AI assistant that compares experience and skills to the job description and highlights potential matches for our recruiting team. Candidates can choose to opt out of AI résumé screening when applying.

We also use AI to record and transcribe interviews to promote accuracy and equity. Transcripts may be reviewed by HR to confirm that all candidates are treated respectfully and evaluated fairly. Candidates can opt out of this transcription feature at any stage.

While AI helps us stay organized and consistent, every decision to move a candidate forward is made by real people. Our recruiting and hiring teams remain hands-on throughout the process and use AI only as a tool, not as a decision-maker for how to find talent.

At Marcus Thomas, we believe diversity is a strength and that great ideas come from different perspectives. We’re committed to creating opportunities for talented individuals who have been historically underrepresented in our industry and to fostering an inclusive culture where everyone can grow, thrive and do their best work.

We encourage women, people of color, LGBTQIA+ individuals, immigrants, people of all religions and nationalities, and people with disabilities to apply. All qualified applicants will receive consideration for employment regardless of race, color, religion, sex, sexual orientation, gender identity or expression, national origin, age, marital status, protected veteran status, or disability.
