Remote | COBOL Software Engineering Consultant — $120–$150/hour in London

We are sharing a specialised remote consulting opportunity for U.K.-based software engineers with experience in COBOL, software engineering, legacy systems, technical evaluation, code review, and structured engineering problem-solving. This role supports current and upcoming remote consulting opportunities focused on AI-assisted software engineering evaluation, high-quality technical training data, COBOL-related engineering tasks, code reasoning, and structured project execution. Selected professionals will translate real-world software engineering expertise into structured examples, review AI-generated technical outputs, and provide detailed feedback based on practical engineering experience.

Key Responsibilities

• COBOL Engineering Task Creation & Documentation
  • Create structured software engineering tasks involving COBOL, legacy system logic, debugging scenarios, code comprehension, or technical problem-solving.
  • Document engineering workflows, implementation approaches, code reasoning, and expected solution paths clearly.
  • Translate real-world software engineering experience into task-based deliverables, technical examples, and structured evaluation materials.
  • Support work involving legacy codebases, enterprise system logic, data processing workflows, procedural programming, or related software engineering topics depending on project needs.
• Technical Review & AI Output Evaluation
  • Review and refine AI-generated code, technical explanations, debugging steps, software design suggestions, or COBOL-related engineering outputs.
  • Evaluate outputs for correctness, completeness, maintainability, clarity, and alignment with practical software engineering standards.
  • Identify inaccurate logic, missing edge cases, weak reasoning, unclear implementation steps, or technically incorrect assumptions.
  • Validate content against professional software engineering experience, COBOL knowledge, and real-world development practices.
• Structured Feedback & Quality Control
  • Provide clear written feedback explaining engineering reasoning, code behavior, technical tradeoffs, and quality concerns.
  • Follow detailed task instructions, review rubrics, quality criteria, and project-specific standards accurately.
  • Review discrete technical deliverables and identify areas for improvement.
  • Collaborate through remote project workflows to improve AI-assisted software engineering outputs and training data quality.

Ideal Profile

• At least 5 years of full-time software engineering experience.
• Professional experience working with COBOL in production, enterprise, legacy systems, modernization, maintenance, debugging, or related engineering contexts.
• Work experience at a large technology company, product-led software company, enterprise software environment, or comparable high-quality engineering organization.
• Strong ability to reason through code, explain technical decisions, and evaluate engineering outputs clearly.
• Experience reviewing code, debugging technical issues, documenting implementation logic, or creating engineering tasks.
• Strong attention to detail and ability to identify incorrect assumptions, incomplete reasoning, code-quality issues, or missing requirements.
• Comfort reviewing AI-generated software engineering content and applying detailed evaluation criteria.
• Excellent written communication skills.
• Ability to work independently in a remote, asynchronous, project-based environment.
• Current U.K. location.

Nice to Have

• Senior-level experience in software engineering, systems programming, legacy modernization, enterprise applications, financial systems, mainframe environments, or large-scale production systems.
• Familiarity with COBOL-related tools, mainframe workflows, batch processing, data pipelines, database interactions, or enterprise integration patterns.
• Experience creating technical documentation, coding assessments, debugging exercises, training materials, or structured engineering evaluation tasks.
• Experience reviewing AI-generated code, rubric-based technical assessments, code explanations, or software engineering benchmark tasks.
• Ability to explain complex technical concepts clearly for both specialist and non-specialist audiences.

Why This Opportunity

• Apply COBOL and software engineering expertise to structured remote project work.
• Contribute to high-quality AI-assisted software engineering evaluation and technical training workflows.
• Use practical engineering judgment in a focused review and task-creation environment.
• Work on discrete deliverables aligned with software engineering background and subject-matter expertise.
• Remote structure with competitive compensation.

Contract Details
