Job description

Backstory helps companies understand the state of their revenue business by answering questions that span customer interactions, sales activity, pipeline health, and deal execution. The platform operates over trillions of sales activities, millions of deals, and more than 160 million business contacts, giving customers a unified view of the signals that drive revenue. Companies such as Nvidia, OpenAI, AMD, Red Hat, and Databricks rely on Backstory to surface risks, identify opportunities, and understand what's happening across their business.

Backstory is building AI systems that reason over massive amounts of enterprise data to help business leaders understand what's happening in their business and what to do next. We work at the intersection of large language models, retrieval, evaluation, distributed data systems, and product design, turning billions of signals from across the enterprise into insights people can trust. The underlying challenges span reasoning, search, ranking, data quality, knowledge representation, and operating AI systems against continuously evolving real-world information.

As a Senior Software Engineer on the Matching team, you will work on Backstory's foundational technology — matching business activities to business context. You will handle a vast amount of business data, perform data-driven research, design and develop algorithms and microservice architecture, write machine learning and automation code, and build scalable systems that power the AI-engine behind Backstory's products.

We value ownership highly — the ability to take an idea through all the stages from conception to shipping a product. This reflects throughout our company, but is especially true in engineering. As an engineer at Backstory, you'll be a part of a highly independent and autonomous team. Since we're building out a robust data layer that needs to be presented elegantly to the end-user, you'll be working with a large array of different technologies and fields. Expect lots of interesting challenges.

What applying to People.ai usually looks like

Based on publicly available information, candidates applying through Lever, the ATS used by People.ai, can generally expect a structured but streamlined process. Applications typically begin with an online submission through a Lever-hosted careers page, followed by an initial recruiter screen if the profile aligns with role requirements. From there, the process may include multiple stages such as hiring manager conversations, functional or technical assessments, and panel interviews with cross-functional team members, depending on the role type—whether in sales, customer success, engineering, or product. Communication is often handled directly through Lever's system, including automated acknowledgments and status updates. Response times vary based on internal hiring needs and team availability, so candidates should follow up politely if they have not heard back. Overall, the experience tends to be organized, transparent, and candidate-friendly relative to other ATS platforms.
