What is a senior engineer?

Senior engineers develop and design software programs and applications, but are designated senior because they have more extensive knowledge and years of experience than other engineers on their team. As a senior engineer, you work closely with company managers to ensure the software is created to the required specifications and must troubleshoot issues with applications when they arise. Most senior engineers have mastered a specific set of programming languages, databases, and operating systems.

What is a senior engineer?

A Senior Engineer is an experienced professional responsible for designing, developing, and overseeing complex engineering projects. They often lead teams, mentor junior engineers, and ensure that technical solutions meet organizational goals and industry standards. Senior Engineers are typically experts in their field, possessing advanced problem-solving skills and a deep understanding of relevant technologies and methodologies. Their role also often involves collaborating across departments, managing timelines, and contributing to strategic planning.

How does a senior engineer typically mentor junior team members, and what impact does this have on the team's success?

Senior Engineers often play a key role in mentoring junior developers by providing guidance on technical challenges, reviewing code, and sharing best practices. This mentorship helps foster a collaborative environment where less-experienced team members can develop their skills more rapidly. As a result, the entire team benefits from improved code quality, faster problem-solving, and a culture of continuous learning. Senior Engineers also help set standards and encourage professional growth, which contributes to the overall success and cohesion of the engineering team.

What are the key skills and qualifications needed to thrive as a senior engineer, and why are they important?

To thrive as a Senior Engineer, you need advanced technical expertise in your engineering discipline, a relevant degree, and several years of industry experience. Familiarity with project management software, CAD tools, and compliance with engineering standards or certifications like PE (Professional Engineer) is typically required. Critical thinking, leadership, and effective communication are essential soft skills for mentoring teams and managing complex projects. These skills and qualities ensure successful project delivery, innovation, and strong team performance within engineering environments.

This position will play a key role in the migration of three major legacy applications currently operating in a NOMAD environment. The successful candidate will help evaluate, design, and execute migration strategies to move these applications either to a NOMAD-based MVS environment or directly to an MVS platform while ensuring uninterrupted support for critical HR and Timekeeping functions used by 5,000–7,000 employees statewide.

This is a highly visible position requiring strong technical expertise, business interaction skills, and the ability to collaborate across Mainframe, MVS, and business teams.

  • Analyze existing NOMAD applications, data structures, business rules, and dependencies.
  • Design and develop solutions supporting modernization and migration initiatives.
  • Work closely with business stakeholders, HR teams, payroll personnel, and operational users to gather requirements and address production issues.
  • Troubleshoot application, database, batch, and interface issues within NOMAD and MVS environments.
  • Develop and maintain technical documentation, data mappings, and migration artifacts.
  • Support system testing, integration testing, user acceptance testing, and production deployments.
  • Participate in code reviews, knowledge transfer activities, and application support rotations.
  • Collaborate with senior developers and cross-functional technical teams to ensure successful project delivery.

The team supports both NOMAD and MVS platforms and works closely with business users across the department.

Required QualificationsTechnical Skills
  • 5+ years of experience developing and supporting NOMAD applications.
  • Strong knowledge of NOMAD database structures, dictionaries, attributes, segments, and reporting capabilities.
  • Experience with NOMAD commands, queries, screens, reports, and application development.
  • Extensive Mainframe development experience.
  • Experience working within MVS/zOS environments.
  • Strong understanding of batch processing, JCL, and job scheduling.
  • Experience with data migration and legacy application modernization initiatives.
  • Knowledge of database design, data analysis, and application troubleshooting.
  • Experience supporting large enterprise business applications.
Business & Communication Skills
  • Ability to communicate effectively with both technical and non-technical stakeholders.
  • Experience working directly with business users to gather requirements and resolve issues.
  • Strong analytical and problem-solving skills.
  • Ability to work independently in a small team environment.
  • Experience supporting production-critical systems with high visibility.
Preferred Qualifications
  • Experience supporting Human Resources, Payroll, Benefits, or Timekeeping systems.
  • Experience working within government organizations or large public-sector environments.
  • Knowledge of employee lifecycle processes and workforce management systems.
  • Experience participating in platform migration or data conversion projects.
  • Familiarity with legacy system modernization strategies.
