Software Engineer | MBA @ Chicago Booth | Stanford Engineer

Who We Are

McMaster-Carr is a privately held e-commerce company trusted by industrial customers for over 120 years. We help professionals—from engineers to facilities teams—work more efficiently and precisely by offering the right products, delivering them quickly, and making it easy to find what they need. Our industry-leading website and logistics systems bring over 300,000 customers to our site daily—and we’re just getting started.

How You’ll Make an Impact

Our technology team builds the software that powers our e-commerce experience and our world-class operations. From customer-facing web features to distribution center automation, we design and scale critical systems that enable McMaster-Carr to deliver same-day or next-day orders reliably and efficiently.

As a Senior Software Engineer, you’ll work on projects like:

• Building modern web experiences using React, Storybook, and experimentation frameworks to improve how customers find what they need and solve problems.
• Optimizing front-end and back-end code and infrastructure to make performance a competitive advantage.
• Designing scalable automation systems that integrate with third-party technologies and streamline distribution center operations.
• Creating custom software and algorithms that improve speed, accuracy, and quality across fulfillment and shipping.
• Exploring the integration of GenAI tools to improve customer support and internal workflows

What You’ll Do

As a Senior Software Engineer, you’ll play a key tech leadership role on high-impact projects. You will:

• Own the full lifecycle of projects—from research and design to development, deployment, and iteration.
• Write high-quality, maintainable, and scalable code using object-oriented design and SOLID principles.
• Improve system architecture, testing, and monitoring to ensure reliability and performance.
• Mentor other engineers through code reviews, technical guidance, and knowledge sharing.
• Collaborate cross-functionally with operations, product, and UX teams to ensure business value and user impact.
• Contribute to long-term technical strategy while remaining close to the details of execution.

This role is a pathway to senior technical leadership or people management—your growth is determined by your impact, not by tenure.

Cash Compensation

• Total cash compensation is generally around $235,000 to $310,000 and includes a profit sharing based on company profitability.
• You will also receive a relocation stipend and signing bonus.
• Informal and formal mentorship
• Employee resource groups
• Medical, dental, pharmacy, and vision plans with no monthly premiums

Family & Future

• Paid parental leave for all new parents
• Adoption and surrogacy assistance
• First-time home buyer assistance
• Industry-leading company-funded retirement accounts

Time Off

• Paid vacation and personal time

Who You Are

We’re looking for curious, driven engineers who thrive in collaborative environments and love solving hard problems. Ideal candidates will have:

• Experience designing and delivering large-scale, service-oriented systems.
• Strong proficiency in compiled languages such as C#, Java, C++, or Rust.
• A thoughtful, analytical approach to problem-solving and software design.
• Clear, confident communication skills across technical and non-technical audiences.
• Interest in mentoring, coaching, and growing as a leader.
