ENGINEERING Principal Mainframe Developer - HLASM Remote, United States See more
Dynatrace · $161,000–$241,000 (stated in the posting)
Your role at Dynatrace
Let’s be clear: this is not a typical mainframe role.
At Dynatrace, we’re redefining what’s possible on the mainframe - bringing AI-driven observability to the most critical systems in the world. Our OneAgent runs in millions of environments, and we’re going deeper into z/OS CICS internals to deliver visibility that simply doesn’t exist anywhere else. We’re looking for engineers who don’t just write code, they understand how systems actually work at the lowest levels.
If you live in HLASM, read dumps like a second language, and care about performance down to the instruction level, keep reading.
What You'll Own
- Build low-level, high-performance instrumentation inside CICS and z/OS
- Push the limits of what’s possible with HLASM
- Design and ship features used by the largest enterprises on the planet
- Diagnose complex behavior using dumps, traces, and deep system insight
- Deliver code that runs in mission-critical environments where overhead is unacceptable
- Work directly with a small, elite team of highly experienced engineers
- Raise the bar—technically and operationally
Why This Role Stands Out:
- You’ll work on problems most engineers never get access to
- Your code will run in the most demanding production environments in the world
- You’ll join a team that prioritizes deep expertise over process
- You’ll help shape the future of AI-powered mainframe observability
This Is For Engineers Who:
- Obsess over performance, efficiency, and control
- Want to go deeper than application-level development
- Take pride in solving problems most people don’t even understand
What will help you succeed
Must Have:
- 7+ years of real-world HLASM experience
- Deep expertise in z/OS internals, CICS internals, systems programming and runtime behavior
- Strong hands-on experience with CICS
- Daily proficiency with JCL, SDSF, and USS
- Proven ability to analyze dumps, traces, and performance bottlenecks
- Working knowledge of COBOL, PL/I, or C for testing and debugging
Nice to Have:
- Experience with DB2, MQ, networking, CTG, security, or WebSphere (WAS)
- Familiarity with z/OS Connect or modern hybrid mainframe architectures
- Some Java experience
- AI experience
