What is a mainframe developer?

Mainframe Developers are specialized software engineers who design, develop, maintain, and troubleshoot applications on mainframe computer systems, such as IBM's z/OS. They typically work with languages like COBOL, JCL, and CICS, and are responsible for ensuring the performance, security, and reliability of mission-critical business applications. Mainframe Developers are commonly employed in industries like banking, insurance, and government, where large-scale, high-volume transaction processing is essential.

What are the key skills and qualifications needed to thrive as a mainframe developer?

To thrive as a Mainframe Developer, you need expertise in programming languages such as COBOL, JCL, and SQL, along with a strong understanding of mainframe operating systems and batch processing concepts. Familiarity with tools like IBM z/OS, DB2, CICS, and version control systems is typically required, and certifications from IBM or related organizations can be beneficial. Strong problem-solving abilities, attention to detail, and effective communication skills help Mainframe Developers excel in troubleshooting and collaborating with cross-functional teams. These skills are crucial for maintaining, optimizing, and modernizing legacy systems that are vital to many large organizations’ operations.

What are some common challenges mainframe developers face when integrating legacy systems with modern applications?

Mainframe Developers often encounter challenges such as ensuring compatibility between legacy systems and newer technologies, managing data migration without disrupting business operations, and maintaining the security of sensitive data. Effective communication with cross-functional teams, such as application developers and infrastructure engineers, is essential to address these challenges. Staying updated on both mainframe and modern programming practices helps ease integration and ensures long-term system reliability.

What is the difference between Mainframe Developer vs Mainframe Analyst?

AspectMainframe DeveloperMainframe Analyst

Work EnvironmentDevelopment teams, coding in mainframe environmentsSupport teams, system analysis, user support
Industry UsageFinancial services, insurance, government agenciesFinancial institutions, healthcare, government agencies

While Mainframe Developers focus on creating and implementing mainframe applications, Mainframe Analysts primarily analyze, troubleshoot, and maintain existing systems. Both roles require similar technical skills and often work within the same industries, but their core responsibilities differ in development versus support and analysis.

Is a mainframe developer a good career?

A mainframe developer is a specialized IT professional who maintains and develops applications on mainframe systems, which are used by large organizations for critical data processing. The role offers stable employment, competitive salaries, and opportunities to work with legacy technologies like COBOL and JCL, but it may require ongoing learning of evolving mainframe tools and certifications. Overall, it can be a good career for those interested in enterprise computing and system stability.

Is a mainframe developer hard to learn?

Mainframe developers typically need to learn specialized programming languages like COBOL and understand mainframe environments, which can have a steep learning curve for beginners. However, with prior programming experience and training, acquiring the necessary skills is achievable, and many employers offer on-the-job training or certification programs.

Is mainframe developer still in demand?

Mainframe developers are still in demand in industries such as finance, insurance, and government, where legacy systems remain critical. They typically work with COBOL, JCL, and mainframe environments, and demand depends on the organization's reliance on mainframe technology and ongoing maintenance needs.

Job description

About Us:
Based in San Francisco, California, Turing is the world’s leading research accelerator for frontier AI labs and a trusted partner for global enterprises deploying advanced AI systems.

Turing supports customers in two ways: first, by accelerating frontier research with high-quality data, advanced training pipelines, plus top AI researchers who specialize in software engineering, logical reasoning, STEM, multilinguality, multimodality, and agents; and second, by applying that expertise to help enterprises transform AI from proof of concept into proprietary intelligence with systems that perform reliably, deliver measurable impact, and drive lasting results on the P&L.

Project Overview:
As a Software Engineering evaluator, you will create cutting-edge datasets for training, benchmarking, and advancing large language models, collaborating closely with researchers. This includes curating code examples, providing precise solutions, and making corrections in Python, JavaScript (including ReactJS), C/C++, Java, Rust, and Go; evaluating and refining AI-generated code for efficiency, scalability, and reliability; and working with cross-functional teams to enhance enterprise-level AI-driven coding solutions.

What Does a Typical Day Look Like?
  • Working on AI model training initiatives by curating code examples, building solutions, and correcting code in Python, JavaScript (including ReactJS), C/C++, Java, Rust, and Go.
  • Evaluate and refine AI-generated code to ensure that it is efficient, scalable, and reliable.
  • Collaborate with cross-functional teams to enhance AI-driven coding solutions against industry performance benchmarks.
  • Build agents that can verify the quality of the code and identify error patterns.
  • Hypothesize on steps in the software engineering cycle (prototyping, architecture design, API design, production implementation, launch, experiments, monitoring, operational maintenance) and evaluate model capabilities on them.
  • Design verification mechanisms that can automatically verify a solution to a software engineering task.

Required Skills:
  • 3+ years of software engineering experience.
  • Strong expertise in building full-stack applications and deploying scalable, production-grade software using modern languages and tools.
  • Deep understanding of software architecture, design, development, debugging, and code quality/review assessment.
  • Excellent oral and written communication skills for clear, structured evaluation rationales.

Engagement Details:
  • Commitment: flexible engagement, minimum 10 hrs/week, up to 40 hrs/week (partial PST overlap required).
  • Type: Contractor (no medical/paid leave).
  • Duration: 1 month (starting next week; potential extensions based on performance and fit).
  • Location: Candidates must be based out of US, Canada or WEU countries (UK, Netherlands, Italy, Germany).

Note: As part of assessments you will go through an AI video interview.
