Role Title: COBOL Developer Role Type: Contractor Location: Remote micro1 is engaging COBOL Developers to contribute their expertise to a high-impact customer project. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.
Scope of Work
- Analyze, interpret, and provide guidance on existing COBOL codebases for the creation of AI training data.
- Develop clear, accurate documentation of COBOL logic, workflows, and business rules to inform AI-driven systems.
- Evaluate sample code and project scenarios, offering expert feedback and identification of potential edge cases or ambiguities.
- Review and annotate COBOL scripts or pseudo-code, supporting the development of robust machine learning datasets.
- Contribute to designing test cases and scenario outlines that represent real-world COBOL applications.
- Collaborate with project coordinators and other technical experts through effective written and verbal communication.
- Ensure technical accuracy and completeness in all submitted materials to enhance AI learning outcomes.
Preferred Qualifications
- Proven experience and deep proficiency in COBOL development across diverse business domains.
- Strong analytical skills with the ability to decode complex legacy systems and articulate their function.
- Demonstrated capability to produce precise, user-friendly technical documentation.
- Exceptional written and verbal communication skills, with attention to clarity and detail.
- Previous experience with large-scale migration, integration, or modernization projects (a plus).
- Familiarity with mainframe environments and related tooling.
- Ability to work autonomously, manage deliverables, and meet project milestones in a remote setting.

Frequently Asked Questions
Can I apply to Micro1 from outside the US or UK?
Yes. Micro1 accepts applicants from most countries worldwide, unlike DataAnnotation or Outlier, both of which cap access to a handful of English-speaking countries. Most roles still require strong written and spoken English.
Does Micro1 monitor your computer while you work?
On many projects, yes, through time-tracking tools that take periodic screenshots to verify active hours. Check the specific project's requirements before accepting if desktop monitoring is a dealbreaker.
What does the Micro1 application process look like?
Expect a screening interview with Zara, Micro1's AI recruiter. Prepare for it like a real video call: good lighting, clear audio, verbal answers to technical questions. A human manager reviews the recording afterward, and some roles add a short skills assessment on top.
Is AI training work the same as traditional consulting?
No. Instead of client deliverables, you're given complex scenarios to evaluate: grading the AI's logic, correcting its hallucinations, and supplying expert-level reasoning it doesn't have on its own. The job is closer to teaching than consulting.
Why do these AI training roles pay so much?
Because general knowledge isn't what's being tested. The model already knows the basics; what it needs is expertise on edge cases, the rare, difficult, highly technical judgment calls only a senior professional in the field would make correctly.
What does the day-to-day workload look like for elite-expert AI training roles?
Slow and deep, not fast and repetitive. A single task can take 45-60 minutes of researching citations or verifying complex calculations. Quality is what's being measured here, not throughput.
What does Data Science work look like for a Mainframe Developer (COBOL)?
Tasks here are scoped to Data Science, not generic labeling. As a Mainframe Developer (COBOL), expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Data Science) rather than following a one-size-fits-all rubric. If you don't have hands-on Data Science background, this is likely not the right listing to start with.
What does the 'openings' count on this listing mean?
It's Micro1's live count of how many candidates it's still trying to place for this specific role, 25 right now, not a countdown on your individual application. A higher number signals more active demand; it doesn't lower the bar for acceptance.
What happens when I click Apply on this listing?
You'll be taken to Micro1's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
