Who We Are
At JuiceLabs (part of HumanX), we're pushing the boundaries of what AI can elevate human
insights and creativity. We're a tight-knit team of experienced founders who are committed on
solving real-world problems for the domains of advertising, consumer insights and ecommerce.

The Opportunity

This isn’t your average engineering role. As our AI/ML Engineer, you’ll work closely with our
Cofounder/CTO to shape the next generation of AI-powered tools. You’ll have a front-row seat
to strategic decision-making and the chance to turn bold ideas into reality. Your work will directly
empower our Insights team to uncover game-changing trends and our Creative team to push
the boundaries of imagination—all while solving complex, real-world challenges with state-of-
the-art technology.

We’re looking for someone who doesn’t just write code but takes ownership of outcomes. You’ll
be entrusted with high agency to design, build, and refine systems that scale, delight, and
deliver measurable impact. If you’re excited by the idea of bridging AI research with production-
grade solutions—and thrive in a collaborative, fast-paced environment—this is the role for you.

What You’ll Do

● Collaborate with Leadership: Partner directly with the Cofounder/CTO to define the
technical roadmap for AI tools that supercharge our Insights and Creative teams,
translating high-level vision into actionable systems.

● Build Cutting-Edge AI Solutions: Design, develop, and fine-tune machine learning
models—including large language models (LLMs)—to power intelligent, intuitive tools
that solve real user needs.

● Engineer Robust Systems: Write clean, scalable, and production-ready code, from AI
evaluations and LLM response generation to backend architectures that stand the test of
time.

● Innovate with Purpose: Leverage your experience in prompt engineering to craft AI
interactions that are precise, reliable, and delightful for end users.

● Own End-to-End Projects: Take full accountability for your work, from ideation and
prototyping to deployment and iteration, ensuring our tools perform at their peak in
production environments.

● Push the Envelope: Experiment with personal AI projects and bring fresh ideas to the
table, helping us stay ahead of the curve in a rapidly evolving field.

Who You Are

You’re a self-starter with a passion for AI and a track record of turning complex concepts into
tangible results. You’re comfortable wearing multiple hats—part coder, part innovator, part
communicator—and you thrive in environments where you can take initiative and drive impact.
Specifically, you bring:

● Technical Mastery:
○ Fluency in Python and hands-on experience with PyTorch, scikit-learn, and
Hugging Face for building and fine-tuning ML models.
○ Proven ability to write robust AI code, including evaluation frameworks,
grounded in best practices.
○ Expertise in designing production-grade backend architectures that scale
seamlessly.
○ Experience with cloud platforms like Google Cloud Platform (GCP), AWS, and
Azure to deploy and manage AI solutions.

● Real-World AI Experience:
○ A portfolio of personal AI projects that showcase your creativity and technical
depth.
○ Professional experience applying AI at work, including prompt engineering to
optimize model outputs.
○ A history of working on ML projects, from experimentation to deployment, with a
focus on measurable outcomes.

● High Agency & Ownership:
○ A proactive mindset—you see challenges as opportunities and take the lead to
solve them.
○ Comfortable navigating ambiguity and driving projects forward with minimal
hand-holding.

● Communication That Connects:
○ Strong ability to articulate technical concepts to both technical and non-technical
stakeholders—because great prompt engineering starts with clear thinking.
○ A collaborative spirit that fuels teamwork and aligns efforts toward shared goals.

Why Join Us?

● Impact: Your work will directly shape tools that redefine how our Insights and Creative
teams operate, with ripple effects across the company.
● Influence: Collaborate elbow-to-elbow with our Cofounder/CTO, gaining unparalleled
exposure to strategic leadership and decision-making.
● Growth: Tackle some of the toughest problems in AI today, with the freedom to
experiment, learn, and grow in a supportive, forward-thinking environment.
● Culture: Join a team that values curiosity, ownership, and bold ideas—where your voice
matters and your contributions shine.
