Scientist – NLP / Generative AI<\/span><\/b>
<\/p>
Location:
Hybrid – Arlington, Virginia<\/span>
<\/p>
Employment
Type: Full -time<\/span>
<\/p>
<\/p>
BizFirst
is assisting our client with the hiring of a Data Scientist specializing in
natural language processing and generative AI to help the organization move
from early experimentation into production -ready AI capabilities. This is a
hands -on research and engineering role where you will own the design and
delivery of NLP and GenAI solutions applied directly to the client’s most
complex internal workflows.<\/span>
<\/p>
Our
client is a mid -market professional services organization that is actively
rethinking how it designs and executes its core business operations through
artificial intelligence and automation. The company is building a dedicated AI
capability to embed machine learning and generative AI into its most critical
internal workflows – from decision support and process automation to real -time
analytics and intelligent document processing.<\/span>
<\/p>
<\/p>
What
will you do<\/span><\/b>
<\/p>
The
ideal candidate brings 5–8 years of applied data science experience with a deep
specialization in NLP and a working command of modern generative AI techniques.
You have built production NLP systems, worked with transformer -based
architectures, and have direct experience with large language models –
including fine -tuning, prompt engineering, and retrieval -augmented generation
(RAG). You are comfortable moving between research and engineering as the work
demands.<\/span>
<\/p>
<\/p>
Responsibilities:<\/b>
<\/p>
• <\/span><\/span>Design
and build NLP and generative AI solutions applied to internal business
processes, including document understanding, classification, summarization, and
conversational AI.
<\/p>
• <\/span><\/span>Develop,
fine -tune, and evaluate large language models and transformer -based
architectures for domain -specific applications.
<\/p>
• <\/span><\/span>Build
and iterate on retrieval -augmented generation (RAG) systems, embedding
pipelines, and vector search infrastructure.
<\/p>
• <\/span><\/span>Work
closely with business and operations stakeholders to scope problems, define
evaluation criteria, and validate model outputs against real -world
requirements.
<\/p>
• <\/span><\/span>Analyze
and interpret model behavior, identify failure modes, and develop mitigation
strategies to ensure reliable, responsible outputs.
<\/p>
• <\/span><\/span>Collaborate
with ML engineers and platform teams to move experiments into production
pipelines.
<\/p>
• <\/span><\/span>Document
experimental methodology, data lineage, and model evaluations to support
reproducibility and knowledge sharing.
<\/p>
• <\/span><\/span>Stay
current on developments in NLP research and GenAI tooling, bringing relevant
advances into the team’s work quickly.
