Why This Job is Featured on The SaaS Jobs
Applied AI engineering roles are increasingly central in SaaS as products shift from workflow software to systems that embed decision support and automation. This listing stands out because it sits at that intersection of platform engineering and product delivery, where model behavior, evaluation, and user experience need to operate reliably in an enterprise setting. The domain focus on legal and professional services also reflects a broader SaaS pattern: vertical products where accuracy, traceability, and trust matter as much as raw capability.
For a long-term SaaS career, the work described signals exposure to the full loop that differentiates durable AI features from demos: data collection, experimentation, offline and online measurement, and iterative improvements tied to real product outcomes. Experience building pipelines like retrieval and multi-step workflows maps well to other SaaS environments adopting LLMs, especially where teams must balance state of the art techniques with operational constraints.
This role is best suited to engineers who prefer ownership across the stack and who enjoy translating ambiguous product problems into measurable systems. It fits professionals who are comfortable collaborating closely with domain experts and who want their engineering decisions to shape how customers experience an AI-enabled SaaS product.
The section above is editorial commentary from The SaaS Jobs, provided to help SaaS professionals understand the role in a broader industry context.
Job Description
Why Harvey
At Harvey, we’re transforming how legal and professional services operate — not incrementally, but end-to-end. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.
This is a rare chance to help build a generational company at a true inflection point. With 500+ customers in 50+ countries, strong product-market fit, and world-class investor support, we’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.
Our team is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle — from early thinking to long-term outcomes. We stay close to our customers — from leadership to engineers — and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.
At Harvey, the future of professional services is being written today — and we’re just getting started.
Role Overview
As an Applied AI Engineer on the Engineering team at Harvey, you will own and lead engineering projects across our various product lines. We are looking for individuals who have worked across the stack on incredible products and have experience building products where machine learning models are a core component.
This role is based in New York City, NY. We use an in-person work model and offer relocation assistance to new employees.
What You'll Do
Conduct data collection, experimentation, and analysis to drive algorithmic development for RAG and multi-step AI pipelines.
Zero-to-one product development: rapidly prototype, evaluate, integrate, and test new product features in close partnership with our legal team.
Develop new AI native workflows: implement streaming, long-running tasks, procedural UX, etc. for new AI tasks, finding the balance between state-of-the-art and pragmatism.
Representative Projects
Partner with our legal team to design and implement a method for evaluating the correctness of document citations. Use this to build a large dataset of ground-truth citations and then improve our core citation algorithm. You can read about some of our work on evaluation and citations here (1, 2, 3).
Make targeted improvements to our RAG pipelines to improve answer quality for user questions over corpuses of complex data, like massive banks of spreadsheets or Japan’s tax code.
Design and build systems that leverage state-of-the-art LLMs from multiple model providers, including custom models.
Work across the stack and with our legal team to create seamless multi-step AI workflows for complex legal tasks, like corporate merger due diligence.
What You Have
7+ years of experience (post-BS/MS) in an engineering role.
Experience with shipping a scaled and impactful product powered by machine learning: how to use offline datasets, online experiments, and recent research to build simple and high performance systems. Prior experience with LLMs and retrieval pipelines is not required.
Track record of shipping reliable products and a strong attention to detail.
Experience building backend platforms that can support multiple product lines.
Grit - experience working at early-stage startups is a plus.
Compensation Range
$201,000 – $264,000 USD
