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
Primary RoleDesigning, coding, and testing mainframe applicationsAnalyzing and maintaining existing mainframe systems
Skills & CertificationsCOBOL, JCL, DB2, certifications like IBM Certified DeveloperCOBOL, JCL, system analysis, troubleshooting skills
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.

Key responsibilities

  • Own end-to-end systems design for key components of the scanning engine, from initial design through implementation, deployment, and ongoing iteration

  • Design and implement high-quality services in Python and Go that power scanning workflows, ensuring code is maintainable, well-tested, and observable

  • Diagnose and resolve complex production issues related to scanning performance, accuracy, and stability, collaborating with SRE/Infra teams where needed

Job description

About the role
We are looking for a Senior Software Engineer to provide technical leadership on Coalition's Scanning Engine & Data Collection team. This team is responsible for the distributed systems that continuously scan the internet and our customers' environments to collect the security data that powers our cyber insurance underwriting and our attack surface management product, Coalition Control.

In this role, you will design, build, and operate large-scale cloud services that run internet-wide and customer-specific scans, ingest and normalize third-party threat intelligence, and surface high-quality findings into our underwriting, risk, and security workflows. You'll work closely with other senior engineers, security, product, and data teams to evolve the architecture of our scanning platform, improve its performance and reliability, and help mentor engineers across a distributed team spanning the US, Canada, and EU.
Responsibilities
  • Own end-to-end systems design for key components of the scanning engine, from initial design through implementation, deployment, and ongoing iteration
  • Design and implement high-quality services in Python and Go that power our scanning workflows, ensuring code is maintainable, well-tested, and observable.
  • Improve performance, scalability, and reliability of the scanning engine, optimizing for large-scale, distributed scanning workloads and strict SLAs.
  • Partner with security, product, and data teams to translate detection and scanning requirements into robust, production-ready systems and APIs.
  • Drive technical excellence and standards in the scanning engine codebase, including code review rigor, design documentation, and best practices for secure coding.
  • Contribute to architecture and roadmap decisions for the scanning platform, evaluating tradeoffs and proposing solutions that balance speed, quality, and risk.
  • Diagnose and resolve complex production issues related to scanning performance, accuracy, and stability, collaborating with SRE/Infra teams where needed.
  • Mentor and support other engineers on the team through design feedback, pairing, and knowledge sharing around systems design and scanning domain concepts.
Skills and Qualifications
  • Strong experience as a Senior Software Engineer (or equivalent) working on backend or systems-level services.
  • Proficiency in at least one of Python or Go, with the ability and willingness to work in both languages over time.
  • Demonstrated experience with systems design for distributed or high-availability services, including clear understanding of scalability, reliability, and observability.
  • Hands-on experience building or maintaining scanning, detection, or similar engine-like systems (e.g., vulnerability scanning, security scanning, data processing pipelines, or similar high-throughput engines).
  • Strong software engineering fundamentals: data structures, algorithms, concurrency, and performance optimization.
  • Experience working in a cloud-native environment (e.g., microservices, containers, CI/CD, monitoring, logging).
  • Ability to collaborate effectively across teams, including product, security, and platform/infra, and communicate tradeoffs clearly to technical and non-technical stakeholders.
  • Proven track record of owning projects end-to-end, from problem definition and design through implementation, rollout, and iteration.
  • Comfort operating in a fast-paced, evolving environment, making pragmatic technical decisions while maintaining quality and security.
  • Experience with code quality practices (testing, static analysis, code reviews) and building maintainable systems.
Bonus Points 
  • Cyber security domain knowledge in scanning through endpoints.

The US base salary for this position ranges from $150,000/year in our lowest geographic market up to $215,000/year in our highest geographic market. Consistent with applicable laws, an employee's pay within this range is based on a number of factors, which include but are not limited to relevant education, skills, job-related knowledge, qualifications, work experience, credentials, and/or geographic location.
