What You'll Be a Part Of

Working at Built In is the chance to help shape a fast-growing company. With venture funding of $30 million to date, we're expanding not just our geographic footprint but our products and technology. You'll also be a part of changing the lives of professionals like you, ambitious people with a passion for tech and love of learning. As a result, you'll understand the impact of your work in a deeply personal, especially meaningful way.

We're looking for an Applied AI Engineer

We're seeking an experienced Applied AI Engineer to design and develop intelligent, agentic systems that take action on behalf of users. You'll work at the intersection of AI automation and user experience—building conversational UIs and AI-driven workflows that solve real-world problems with minimal user input.

This is an ideal role for someone who's passionate about Large Language Models (LLMs), intelligent agents, and the future of user interaction. You'll have the opportunity to shape how AI behaves autonomously within product ecosystems.

How you'll contribute

• Architect and build agentic workflows that can interpret intent, plan tasks, and execute operations on behalf of users.
• Develop and iterate on chat-based user interfaces for rich, dynamic interactions.
• Leverage LLM platforms (e.g., OpenAI, Anthropic) and orchestration tools like LangChain, Semantic Kernel, or custom frameworks.
• Work cross-functionally with backend engineers, product managers, and designers to integrate conversational features into the platform.
• Design robust systems for evaluating agent performance, user feedback loops, and improving reliability.
• Stay current with cutting-edge developments in LLM tools, RAG pipelines, memory/state handling, and prompt engineering.

What you need 

• 4+ years in a Data Science, Machine Learning, or Applied AI role
• Deep experience with Python, LLM APIs, and libraries like transformers, langchain, OpenAI, etc.
• Experience building chatbots or conversational UIs, and strong understanding of natural language processing
• Solid grasp of SQL, APIs, and structured/semi-structured data
• Familiarity with vector databases, tool use orchestration, and agent memory design
• Excellent collaboration and communication skills, especially in cross-functional teams
• Bonus: experience in reinforcement learning, retrieval-augmented generation (RAG), or AI monitoring systems

Why Work With Us

• Help shape intelligent systems that act autonomously in real-world environments
• Be part of a product-led, engineering-driven culture
• Remote-first team with collaborative, flexible work structure
• Opportunities for leadership and technical ownership in AI development

What We Value

We're revolutionizing tech recruitment. So we question everything, because the best answers sit just to the right of a question mark. That's our heritage as a disruptive company — as a company whose future depends on our capacity to innovate with a sense of drive, purpose and urgency. If you join Built In, you will work from this set of values: 

• Be Inclusive, Always. We're committed to a culture where all people are respected, have a say and can be their whole selves. We will uplift and advocate for one another. Always.
• Be Unreasonably Passionate. Our passion is borderline obsessive, and we're ok with that. No one ever built anything great on a "meh." We work with outsized passion to fulfill our mission.
• Be Humble. You don't have all the answers. Luckily, you don't have to. Don't worry about being right. Be humble instead. 
• Stay Curious. Curiosity is a springboard to the future. It can transform the wisp of an idea into a breakthrough. We ask "what if." We work with wonder. It's how we innovate.
• Lead with Solutions. Question everything. But offer solutions as you do. Raise issues. But propose a few answers. For every hole you poke, offer a way to patch it up. 
• Own the Result. We have no time for blame or shame. When you stumble, own it, learn from it + get back to business. 
• Do More. Do more than your job description. Take initiative. Take charge. No job is beneath you, and no job is too big. Be a leader and do more — do whatever it takes. 

Be Inclusive, Always

Research shows that women and other marginalized groups tend to apply to roles only when they check every point on a job description. We encourage you to apply if you meet the majority of qualifications and this role is aligned with your career trajectory.
