What Does a Remote Mainframe Developer Do?

As a remote mainframe developer, you work from home to design, code, test, and configure software and applications used on a mainframe system. Mainframes are large computers with particularly high processing power and are often used for critical tasks like bulk data processing or enterprise resource planning. In this role, you may help ensure all new software is fully backward-compatible, monitor system performance, isolate errors, and work collaboratively with other developers as needed. Most mainframe developers work for larger companies. As a remote employee, you use virtual office software, phone, chat, or email to remain connected to other employees.

How much do mainframe programmers make?

Mainframe programmers typically earn between $70,000 and $120,000 annually, depending on experience, location, and certifications. Senior roles or those with specialized skills in COBOL, JCL, or mainframe tools can command higher salaries, especially in industries like finance and government. Remote positions may also influence compensation levels.

Is mainframe still in demand?

Mainframe developers are still in demand due to the continued reliance of many large organizations on legacy systems for critical operations. Skills in COBOL, JCL, and mainframe environments remain valuable, especially in finance, insurance, and government sectors where mainframes handle high-volume transactions.

What are the key skills and qualifications needed to thrive as a Remote Mainframe Developer, and why are they important?

To thrive as a Remote Mainframe Developer, you need strong programming skills in languages like COBOL, JCL, and experience with mainframe operating systems, often supported by a degree in computer science or related field. Familiarity with tools such as IBM z/OS, DB2, CICS, and version control systems is typically required, along with relevant certifications. Excellent problem-solving abilities, independent work ethic, and effective virtual communication are standout soft skills for this remote role. These skills ensure smooth maintenance, modernization, and support of critical legacy systems in distributed teams.

Can mainframe be replaced by AI?

Mainframe developers work with large-scale, legacy systems that require specialized knowledge of mainframe environments, programming languages, and security protocols. While AI can automate certain tasks like code analysis and testing, it is unlikely to fully replace the need for skilled mainframe developers who manage complex, mission-critical systems. Instead, AI tools are increasingly used to augment their work and improve efficiency.

Does mainframe need coding?

Yes, mainframe developers typically need coding skills in languages such as COBOL, PL/I, or Assembler to create, maintain, and update mainframe applications. Proficiency in these languages is essential for working effectively in mainframe environments and often includes understanding of tools like JCL and DB2. Coding is a core part of mainframe development roles.

How does a Remote Mainframe Developer typically collaborate with on-site teams and manage communication challenges?

As a Remote Mainframe Developer, you'll often work closely with on-site IT teams, business analysts, and project managers through virtual meetings, chat platforms, and shared documentation tools. Effective communication is key, so regular check-ins and proactive status updates help ensure alignment on project goals and troubleshooting efforts. Many companies use agile methodologies, which means you'll likely participate in daily stand-ups and sprint planning sessions remotely. While time zone differences can be a challenge, flexible scheduling and clear communication protocols are common strategies to keep everyone connected and productive.

What is a Remote Mainframe Developer?

Job description

Nuuly is hiring a Senior Software Engineer to join our Technology team. Building performant scalable cloud service environments is hard. Nuuly knows this firsthand, having built a cloud-based microservices platform from the ground up to power our online customer experience and drive the logistics and processing of our garment distribution centers. We're looking for a Senior Engineer with the initiative and expertise to help mature this platform into a stable, scalable, and robust backbone for launching the next wave of Nuuly innovations.

You'll need strong experience designing and building microservices backed by relational and non-relational databases. Solid confidence with JVM-based tools such as Kotlin, Spring, and data persistence with Postgres and other database technologies. You’ll also need a reasonable amount of aptitude in designing and integrating Kubernetes services with cloud-based platform APIs such as Google Cloud Platform (GCP), AWS, or Azure focused on driving toward zero-downtime deployments.

As a Senior Engineer, you'll bring experience that extends beyond personal code contribution: leading design for moderately complex features, driving communication between teams, providing critical feedback, coordinating with others, and providing mentorship as needed. You'll participate in incident response and post-mortem processes to improve system reliability. You should be adept at picking up new technologies and patterns and comfortable discussing and debating the pros and cons of various approaches. Most of all, you should be ready and willing to tackle new challenges with a supportive team of creative and hard-working professionals.


  • Producing architectural proposals and engaging in discussions and decision-making for new features and platform evolution
  • Collaborating with the product team to design solutions for stakeholder features and inform product decisions through technical feasibility analysis
  • Mentoring junior engineers through code review, pair programming, and design discussions
  • Delivering the whole lifecycle of deployable features: design, code, testing, configuration, documentation, deployment, and support
  • Contributing to operational guidelines, system reliability practices, and post-mortem analysis for production incidents
  • Teaching and enforcing development methodologies while proactively identifying improvement opportunities in codebase, tooling, and processes
  • Collaborating with QA and Platform Engineering teams to test code and keep our integrated testing environments unblocked
  • Providing technical guidance to cross-functional teams on integration approaches and system constraints to deliver features and evolve our architecture

  • 5-7 years of software engineering experience with ~2 years of senior-level responsibilities such as taking ownership of designs or projects and working to coordinate work across teams
  • Operational knowledge of one or more server-side object-oriented programming languages (Java, Kotlin, Scala, or other JVM languages preferred; Python, Go, Node/TypeScript also considered)
  • Able to talk comfortably about microservices architecture, distributed system design, streaming data, messaging technologies, and database design patterns
  • Experience and enthusiasm for testing, test-driven development, and building reliable systems
  • Proficient with leveraging AI tools in day-to-day development tasks such as code generation, debugging, and documentation
  • Able to hit the ground running and quickly familiarize yourself with an existing codebase and toolset
  • Able to propose and walk through solutions in technical leadership discussions and communicate effectively across functional teams
  • Operational knowledge of Java, Kotlin, Scala, or other JVM languages (Python, Go, Node/TypeScript also considered)
  • Strong experience designing, building, and operating microservices architectures; expertise with RESTful APIs, HTTP protocols, and service integration patterns
  • Experience with Google Cloud Platform (GCP) or other major cloud providers (AWS, Azure); knowledge of container technologies (Docker, Kubernetes)
  • Hands-on experience with relational databases (Postgres, AlloyDB) and understanding of data modeling, query optimization, and schema evolution.
  • Understanding of distributed system design patterns, consistency models, and trade-offs in microservices architectures  (e.g., Kafka, Spark, Storm , etc.)
AI/LLM Proficiency:
  • Practical experience using Large Language Models (ChatGPT, Claude, Cursor, Windsurf, Copilot etc.) for work tasks
  • Understanding of prompt engineering and how to provide effective context to AI tools
  • Familiarity with structured AI guidance methods (system prompts, rules files, agent configurations)
  • Knowledge of AI tool integration concepts (MCP, connectors, agentic workflows)
  • Ability to identify opportunities where AI can drive efficiency improvements
