Why This Job is Featured on The SaaS Jobs
This Staff Software Engineer, Fullstack role sits at the intersection of modern SaaS delivery and AI-native product development. The listing signals a product-led company building generative AI capabilities into real user workflows, including deep integrations with familiar tools and high-accuracy retrieval and extraction. Within the SaaS ecosystem, that combination of application UX, data-heavy backends, and model orchestration reflects where many teams are heading as AI shifts from features to core platform behavior.
From a career perspective, the work described maps to durable SaaS engineering skills: designing end-to-end systems that ship, operate reliably at scale, and evolve with customer usage patterns. The emphasis on processing large document volumes, building pipelines, and balancing performance with usability aligns with common challenges in mature SaaS products, while still providing exposure to newer patterns around LLM-driven systems and evaluation.
This is best suited to an engineer who prefers broad ownership across frontend and backend, and who enjoys translating messy domain problems into pragmatic software. It also fits someone comfortable collaborating closely with non-technical stakeholders, since the product area depends on tight feedback loops with domain experts.
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
Engineering at Ivo
Engineers at Ivo are inventors. Ivo was first-to-market with:
• An AI agent that lives in MS word and edits the document for you [2023]
• Ditching imprecise embeddings models in favor of agentic RAG [2023]
• Large-scale LLM-based legal fact extraction [2024]
• A legal assistant that can search large contract databases, without sacrificing accuracy [2024]
• Clustering legal documents descended from the same family [2025]
• Automatic deviation analysis to locate buried risk in huge contract databases [2025]
• Merging contracts with their amendments to make a time series of “composite” contracts (a customer actually cried when we showed her this) [2025]
Role
Engineers at Ivo design, create and deploy generative AI products. You’ll work across the stack on:
• Developing full stack generative AI functionality
• Shipping high performance UI code and backend systems that process and analyze millions of contracts reliably
• Designing pipelines that orchestrate LLMs, data extraction, and clustering algorithms at scale
• Collaborating with designers, lawyers and other engineers to re-imagine how lawyers work in the AI age
Mission
Every major business has an in-house legal team, and all of those lawyers are overworked. 80 hour weeks, tight deadlines and contract-reading death marches are the industry norm. Up until recently, there wasn’t anything technology could do to help this situation.
LLMs have given us the ability to give these lawyers their lives back, and at Ivo, that’s our mission.
We’re building an AI-native platform to automate legal drudgery. People love our software - despite high competition, we have the highest trial win rate on the market (85%). We’re genuinely improving people’s lives, and we’re only just getting started.
