Senior Software Engineer II, Backend - Intelligence Team

Who you are

You have 5+ years of backend engineering experience building production systems at scale — you've owned services from design through deployment and have war stories from debugging complex distributed systems issues. You possess deep expertise in Java and Spring — you've shipped high-throughput APIs that handle millions of requests and have strong opinions on service architecture, dependency injection, and testing strategies. Your experience includes working with machine learning models — you understand how to integrate contextual signals into real-time decision-making systems. You are a strong collaborator who can partner closely with product managers and AI teams to translate user problems into technical solutions. You have a knack for improving the scalability, reliability, and performance of data integrations and synchronization pipelines. Mentoring peers and shaping long-term technical strategies is something you enjoy, and you thrive in environments where you can influence the technical direction of projects.

Desirable

Experience with cloud platforms and data-driven systems is a plus, as is familiarity with agile methodologies and cross-functional team dynamics.

As a Senior Backend Engineer II on the Intelligence Backend team, you will design and build scalable backend systems that deliver personalized recommendations and adaptive customer journeys. You will lead the technical direction for services such as the Tasks Recommendation Service, which personalizes onboarding tasks based on each user’s goals and context. You will partner closely with AI, data, and product teams to integrate contextual signals and machine learning models into real-time decisioning systems. Collaborating with product managers, you will deeply understand customer needs, pain points, and workflows, translating user problems into technical solutions that enhance end-user experiences. You will also focus on improving the scalability, reliability, and performance of third-party data integrations and synchronization pipelines. Mentoring peers and helping shape the long-term technical strategy for the Intelligence product will be key aspects of your role.
