Job description

What is Box?

Box (NYSE:BOX) is the leader in Intelligent Content Management. Our platform enables organizations to fuel collaboration, manage the entire content lifecycle, secure critical content, and transform business workflows with enterprise AI. We help companies thrive in the new AI-first era of business. Founded in 2005, Box simplifies work for leading global organizations, including JLL, Morgan Stanley, and Nationwide. Box is headquartered in Redwood City, CA, with offices across the United States, Europe, and Asia.

By joining Box, you will have the unique opportunity to continue driving our platform forward. Content powers how we work. It's the billions of files and information flowing across teams, departments, and key business processes every single day: contracts, invoices, employee records, financials, product specs, marketing assets, and more. Our mission is to bring intelligence to the world of content management and empower our customers to completely transform workflows across their organizations. With the combination of AI and enterprise content, the opportunity has never been greater to transform how the world works together and at Box you will be on the front lines of this massive shift.

Why Box Needs You

As a Software Engineer III (Backend) on the Automate team, you will be at the heart of Box's workflow automation platform — a product that empowers millions of users to automate complex business processes without writing code. The Automate team is a growing organization of ~30 engineers across four specialized teams, responsible for building the intelligent automation engine that enables organizations to transform how they work.

Box Automate is a keystone in Box's overall AI strategy — one of the primary entry points for AI into Box. The platform drives recurring usage, supports upsell to higher tiers, and increases AI token consumption. Launched recently, Automate is scaling rapidly across both external enterprise customers and internal Box use cases (including Shield, Governance, and Archive).

In this role, you will design and develop sophisticated backend systems at the core of the Box Automate workflow engine. You'll work primarily in Java to build and optimize the engine that represents, executes, and manages complex workflows modeled as graphs. You'll tackle algorithmically rich challenges — from graph traversal and optimization to the design of a meta-language that enables dynamic, variable-driven workflow composition. Your work will directly impact how thousands of enterprises automate their most critical business processes.

What You'll Do

• Design and implement backend services powering the Box Automate workflow engine, writing clean, maintainable Java code with a focus on correctness, performance, and scalability.
• Build and optimize algorithms for workflow graph representation, traversal, and execution, ensuring reliable processing of millions of workflow instances daily.
• Develop and extend the Automate meta-language that enables creation of complex, variable-driven workflows beyond standard CRUD operations.
• Collaborate with cross-functional teams including product, design, and infrastructure to define requirements, propose technical solutions, and deliver features on schedule.
• Participate in code reviews, mentor junior engineers, and contribute to engineering best practices and architectural decisions.
• Participate in our on-call rotation, available at all times while on-call to help respond to and triage any issues that arise.
• Attend and engage in weekly stand-ups, team meetings, and manager 1:1s to ensure alignment and continuous improvement.

• You have strong foundations in computer science — ideally with a background in mathematics or computer science — and are comfortable working with graph algorithms, optimization problems, and complex computational concepts.
• You have experience building scalable backend systems, including database design, caching strategies, and asynchronous processing.
• You are able to assess, communicate, and complete project milestones with your manager and team members in a time-sensitive manner.
• You are fluent in English (written and verbal).
