Software Engineer III

Job Description:

Our Opportunity

Chewy is seeking a highly driven and technically strong Senior Software Engineer (SE3) to join our Inventory Technology team in Fort Lauderdale, FL; Boston, MA; or Seattle, WA.

This team owns a suite of critical services that power inventory visibility, placement, availability, and movement across Chewy’s supply chain network. These systems span distributed services and data pipelines supporting both real-time and batch processing at scale.

As a senior engineer, you will play a key role in shaping the technical direction of these systems, acting as an authority across multiple services, mentoring engineers, and helping the team evolve how we build software—particularly through the practical adoption of AI-assisted development and LLM-powered capabilities.

This is not a purely backend role. While deep expertise in backend systems is expected, you’ll operate across the stack when needed and contribute to end-to-end solutions in a complex, system-heavy environment.

What You’ll Do

• Act as a technical owner and domain expert across multiple critical services, driving system understanding, stability, and long-term maintainability

• Provide technical leadership across initiatives, influencing architecture, design decisions, and engineering protocols

• Design and build scalable, resilient distributed systems using Java, Spring Boot, and AWS

• Own and deliver moderately to highly complex features and services end-to-end, from design through production

• Work across backend services, APIs, data pipelines, and, when needed, user-facing applications

• Raise the technical bar of the team through mentorship, design reviews, and hands-on guidance

• Lead the adoption of AI-assisted engineering practices to improve developer productivity, including code generation, testing, and development workflows

• Identify and implement opportunities to embed LLM-powered capabilities into production systems, integrating with existing services and business processes

• Apply strong engineering judgment to ensure solutions are scalable, maintainable, and reliable, balancing speed with long-term quality

• Partner with product, TPMs, and other engineering teams to solve complex supply chain and operational problems

• Drive operational excellence, including system reliability, observability, and performance optimization

What You’ll Need

• Bachelor’s degree in Computer Science, Engineering, or related field

• 5+ years of professional software development experience with increasing technical ownership

• Strong experience with Java (8+), Spring Boot, and microservices architectures

• Proven experience building and operating distributed systems and data pipelines at scale

• Strong understanding of system design, APIs, data modeling, and event-driven architectures

• Demonstrated ability to lead technical initiatives from ambiguous problem spaces through production delivery

• Experience mentoring engineers and contributing to raising team-wide engineering standards

• Experience with AWS, CI/CD pipelines, and infrastructure as code

• Strong communication skills and ability to collaborate across teams

• Ability to operate effectively in fast-paced, ambiguous environments

AI & Modern Development Experience

We are looking for engineers who can apply AI pragmatically in real-world systems and development workflows. This may include:

• Using LLM-powered tools (e.g., Copilot, Cursor, Codex) to improve development efficiency

• Applying LLMs (e.g., OpenAI, Anthropic) to solve engineering or business problems

• Familiarity with frameworks such as LangChain or LangGraph

• Finding opportunities to incorporate AI into existing systems in a safe, maintainable, and scalable way

Bonus

• Experience delivering full-stack applications (e.g., React, Vue)

• Experience integrating AI capabilities into production systems

• Familiarity with spec-driven development or planning workflows

• Background in supply chain, logistics, inventory systems, or e-commerce

• Experience with high-volume data processing or operational systems

Join Us

If you’re excited to own critical systems, mentor engineers, and help shape how AI is applied within modern software development and supply chain platforms, we’d love to hear from you.
