- Model Fine-tuning: Fine-tune transformer models for custom tasks, including text classification, information extraction, and named-entity recognition (NER).
- Conversation Engine Development: Build and maintain scalable pipelines for conversational assistants.
Must-Have Qualifications
- Experience in Machine Learning/AI, focused on large language models and conversational systems.
- Hands-on expertise with OpenAI APIs (ChatGPT, function call) and/or Anthropic Claude; familiarity with open-source LLMs (e.g., Llama, Mistral).

Nice-to-Have

ADP Sales – Why Come, Why Stay
[TEXT] ADP Voice of Sales: Why Come, Why Stay
[MUSIC PLAYING]
[JULIANNA, CENTRIC, DISTRICT MANAGER] My job first out of college was a sales job. I was definitely not given the right tools for success.
[ROMARR, ASSOCIATE SALES MANAGER] First job out of college, I did some consulting with my fraternity. Loved it. It was great. The pay wasn't exactly the greatest. And I wanted to come back to my hometown. ADP was just kind of a way to get back here, make a little bit more money. It was not supposed to be a be-all, end-all situation.
[CAT, VICE PRESIDENT, ADP] I actually worked for a competitor. So I had been in the industry for about five years before coming to ADP. And I had an acquaintance that worked for ADP. And she had gotten promoted, and reached out to me and said, I need you to come work for me. And I kind of laughed it off because I had been doing well working for my competitor.
[CHRISTOPHER, SALE EXECUTIVE, ADP] Graduated high school at 18. Immediately joined the Air Force, where I spent four years. I joined the Air National Guard, did another six years there. And then subsequently became a police officer. My career kind of got cut short there, so I took some time off. I went to school full-time in my 30s. And then ultimately took a job with ADP.
[LAUREN, SALES EXECUTIVE, ADP] I'd worked in the start-up space for a while. So I had some sales experience, but never with an established company.
[JULIANNA] I was just looking on LinkedIn, and I saw the opening for ADP Outside Sales. And I was like, you know what? I'm just going to do it. And I am so, so thankful that I took that plunge.
[ROMARR] I just fell in love with the atmosphere. Coming from an athletic background, the sales environment and the culture that's built at ADP, it motivates you to always want to win. There is always an opportunity for you to be coached to be better. That's what's kept me, now going into my sixth year.
[CAT] I love payroll. I love HCM. And for me, to work for the best of the best, work for the culture that is ADP, it was literally a no-brainer.
[CHRISTOPHER] When I initially got hired by ADP, I had wanted to get into sales previously. And to find an entry-level position in sales that was going to give you all the tools that you needed with really competitive compensation, ADP was it. I didn't know much about ADP at the time, but I found out quickly, within my first few weeks, that the culture was magnificent. The people were just unbelievable. The training program was second-to-none. They really set you up for success from day one.
[LAUREN] Sometimes I'm asked, why have you stayed at ADP so long? I firmly believe that the grass is greener where you water it. And I think that ADP has provided me a safe space to be able to cultivate my career, be able to grow, be able to push myself and challenge myself. And for anyone that's looking to start their sales career, I would absolutely recommend working at ADP.

[DESCRIPTION: Martha Bird speaks. ]
No matter where you are and no matter what time period you're from, we value being part of a community. We want to be close to friends and family. We seek meaning for ourselves as individuals, where we can be acknowledged and recognized.
[DESCRIPTION: Martha walks through an office. ]
My name is Martha Bird. I'm a cultural anthropologist. And I worked for ADP.
[DESCRIPTION: Exterior view of ADP headquarters. ]
I look for patterns. I study beliefs, routines, aspirations, and behaviors to inform the digital tools we're building at ADP.
[DESCRIPTION: Martha views papers under lamplight]
I often look at new technologies in reference to what is the human need behind that.
[DESCRIPTION: Martha stands in a server room. ]
You have the assembly line. You can imagine in the '50s, people had to work at a stationary terminal. And then you get into the PC in the '80s. And now you have the mobile phone. And people can kind of work anywhere.
ADP as a company is really aware of the importance of having a human perspective on technology. And that's one of the reasons I'm here, is to try to surface what it is that people actually need in the tools that they use.
[DESCRIPTION: Martha converses with a colleague in a cubicle. ]
I spend a lot of time deeply hanging out with people. I do a lot of asking questions that seem straightforward to people who are insiders.
[DESCRIPTION: Martha works with a colleague. ]
I'm able to bring together human insights and observations that, when applied, can impact one in six workers in the US.
[DESCRIPTION: Various floors of the office are viewed. ]
When employees work on teams where they feel that they are respected, they have a tendency to produce more. So I think companies understand that in order to create greater productivity, you have to really work on some of these levers of engagement.
At ADP, I feel really supported on a number of levels. I think the company has used all of the factors that conspire to actually make a more productive workforce. I have a great team that respects my opinion. It's about being authentic. It's about being open to diversity and different perspectives. I get to wake up every day and do exactly what I love doing, just really spending time with people, understanding people. It's about tending to other people and tending to yourself.

Text: Scott, VP, Finance Strategy
[SPEECH]
Hi, I'm Scott. I'm a VP in Finance Strategy here at ADP. I've been here for two years.
[MUSIC PLAYING]
[DESCRIPTION]
Text: What is your favorite part of your role?
[SPEECH]
My favorite thing about working here is just the opportunity. And so in my current role-- it's a fairly new role and I get to shape what it is. I get this brand new opportunity to create the finance strategy of the company. And so having that blank sheet of paper and filling it in with what the finance strategy might look like, that's phenomenally exciting.
[MUSIC PLAYING]
[DESCRIPTION]
Text: Why do you stay @ ADP?
[SPEECH]
The reason I stay at ADP and the reason I see a future in ADP is just the career progression. And so one of the things I've found in ADP is you've got people with significant tenure, 20, 25 years of tenure. But within that 25 years, they’ve done 6, 8, 10 different jobs. And so career mobility is big at ADP. And in other companies, as people have moved sideways, it's viewed as a bad thing that you've moved sideways. Here, it's encouraged to get exposure, too. So for myself, I was in the field. And now I'm being exposed to corporate. And then obviously, global is another thing for me to get exposure to. So that's really why I stayed.
[MUSIC PLAYING]
[DESCRIPTION]
Text: What would you tell someone looking to apply to ADP?
[SPEECH]
So to somebody looking outside into ADP, what they really need to know is it's not a payroll company. And I definitely had that perception when I came in. And it's only really once you get inside it that you realize there's so many different facets to ADP. And it wasn't until I really dug into the role and the company that I realized that it was more than payroll. It was a pretty sophisticated technology company that was global in reach.
