Job Details

We are seeking a senior-level Java Engineer to join a high-performing team building a next-generation platform for industrial automation and manless yard operations. This Chicago-based company is launching a secure, scalable, event-driven microservices architecture to transform logistics, steel mills, and warehouse operations-and they need a strong backend builder to help lead the way.

You'll be the most senior engineer on the team (aside from the hiring manager), playing a central role in shaping the technical direction, mentoring junior developers, and driving the evolution of a complex, high-availability platform. This is not a role for someone who just takes tickets-the ideal candidate has built systems end-to-end, sees the big picture, and brings a real-world, hands-on approach to architecture and problem-solving. Required Skills & Experience
  • 10+ years of hands-on Java development experience
  • Deep understanding of system architecture, design patterns, and algorithms
  • Expert-level Spring Boot and Spring Security knowledge
  • Strong grasp of secure communication protocols and auth standards (OAuth2, OpenID Connect, SAML)
  • Experience with network-level protocols (TCP/UDP, REST, SOAP, gRPC, AMQP, MQTT)
  • Proficiency with testing frameworks (JUnit, TestNG)
  • Hands-on experience with containerization (Docker) and scripting (PowerShell, Bash) in Linux and Windows environments
  • Strong fundamentals in refactoring, architecture cleanup, and technical mentorship
  • Proven ability to operate independently and provide technical leadership
  • Git, Gradle, and DevOps toolchain familiarity
Desired Skills & Experience
  • Cloud platform experience (AWS, Azure, Google Cloud Platform)
  • Real-world experience with observability, monitoring, and SRE practices
  • Additional language proficiency (Python, C++)
  • Exposure to a variety of database technologies (SQL, NoSQL, Graph, Time Series)
  • Prior experience in logistics, manufacturing, or industrial automation
  • Experience contributing to platform or infrastructure builds from the ground up
What You Will Be Doing
  • Designing and building scalable backend systems using Java and Spring
  • Leading architecture discussions and refactoring efforts to improve system integrity
  • Implementing secure, high-availability services for real-time industrial environments
  • Mentoring junior developers (especially those based in Chicago)
  • Driving platform-wide decisions and helping shape long-term infrastructure
  • Acting as the technical right hand to the hiring manager on a small, fast-growing team
The Offer You will receive the following benefits:
  • Medical, Dental and Vision Insurance
  • High-impact role as the most senior engineer on the team
  • Chance to lead technical direction and shape the future of an industry-changing platform
  • Hybrid work model: 3 days onsite in downtown Chicago with lake and river views
  • 2 days remote
  • Medical, Dental, and Vision Insuranceetitive compensation
Applicants must be authorized to work in the U.S. on a full-time basis now and in the future.
