Senior Software Engineer — Data Modeling (Europe)

As a Senior Software Engineer on the Data Modeling team, you will help us complete the biggest re-architecturing project in Backstory history - Unified Data Platform (UDP) - that unifies all Backstory products under one architecture and improves the data freshness. You will build and maintain the services, REST APIs, databases, and big data jobs that provide Backstory’s insights.

Working with the larger Engineering and Product teams, you will take “activity” and “CRM objects” data provided by other teams and make it available for consumption to end users, building higher-level customizable insights that power not only our web application, but also use cases like Account 360, Opp 360, search functionality, and our new Generative AI features.

What you will do:

Design, build, and maintain backend services, REST APIs, databases, and big data pipelines that power customer-facing insights and analytics.

Implement and maintain near-real-time stream-based data processing pipelines in collaboration with batch-oriented data refresh workflows.

Develop and evolve a query engine capable of answering complex, cross-deal/account questions and delivering actionable insights for sales managers and executives.

Scale data processing and insights generation pipelines to handle growing volumes of activity data (emails, meetings, transcripts, CRM objects) while managing infrastructure costs.

Collaborate with Engineering and Product teams to translate business and customer needs into robust, well-documented technical solutions.

Follow and promote software development best practices, delivering clean, maintainable, and well-monitored code.

Build internal tooling to enable customer support teams to investigate and resolve support requests in a self-service manner.

Ensure high-quality alerting, dashboards, tracing, and runbooks are in place for all production services.

What you will bring:

5+ years of professional experience building backend systems in an enterprise environment

2+ years of experience programming in Python or Scala

Experience with distributed systems and service-oriented architecture (SOA)

Experience with large-scale data processing frameworks (Spark, Hive, Hadoop, MapReduce, or similar)

Experience with stream processing technologies such as Kafka, Apache Samza, or Apache Storm

Experience with Elasticsearch is a plus

Experience with LLMs or NLP is a plus

Familiarity with analytical databases and ETL pipeline design

Strong analytical and problem-solving skills with a track record of delivering elegant, practical solutions

Experience taking ownership in an unfamiliar or legacy codebase and incrementally improving it

Strong inclination toward automation and reducing manual operational toil

About Backstory.ai:

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.

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.
