What is a Part Time SQL Developer?

A Part Time SQL Developer is a professional who designs, develops, and maintains databases using SQL (Structured Query Language) while working less than full-time hours, often on a flexible or project basis. Their primary duties include writing SQL queries, optimizing database performance, and supporting data-related needs for organizations. Part-time roles are ideal for those seeking work-life balance or supplementing their income, while still contributing valuable technical skills. These positions may be remote or on-site, depending on the employer.

What Does a Part-Time SQL Developer Do?

Standard Query Language (SQL) is a computer language for communicating with databases. As a part-time SQL developer, you help design databases using SQL code. Your duties may also include creating applications that help users interface with databases. After you develop a database or related tools, your responsibilities shift to testing your code to ensure quality and usability. As a part-time developer, you may design and test one data application or one facet of a larger database development project. Since you work part-time, you need to document your work and adhere to the development methodologies that your team is using.

How does working as a part-time SQL Developer typically impact collaboration with full-time team members?

As a part-time SQL Developer, you’ll often coordinate closely with full-time developers, database administrators, and project managers to ensure your work aligns with ongoing projects.

Job description

United States • Remote • Part-Time

Are you an expert at navigating the complex logic of Large Language Models? Welo Data is seeking a technical Prompt Engineer to lead the end-to-end migration of template workflows into high-performance LLM autoraters.

This isn't just about writing prompts—it’s about engineering a technical bridge. You will use advanced APG/APO tools and manual refinement to ensure our automated systems meet (and exceed) human accuracy baselines.

The Mission: Architecting the Future of Rating
  • Technical Migration: Take ownership of the workflow for transitioning templates to LLM autoraters.
  • Optimization Leadership: Run and supervise Automated Prompt Optimization (APO) tools, identifying where logic plateaus and providing the manual "spark" to overcome deadlocks.
  • Metrics-Driven Accuracy: Continuously measure quality against gold data, calculating critical performance metrics like precision, recall, and $F_1$ scores.
  • Edge-Case Engineering: Solve complex scenarios by designing manual prompts that handle anti-patterns and broken logic in legacy architectures.
Project Details
  • Schedule: Part-Time (Flexible hours within project milestones)
  • Location: 100% Remote (Must be based in the United States)
  • Employment Type: Freelance / Independent Contractor
 Who We Are Looking For
  • Linguistic & AI Mastery: 2+ years of experience as a Prompt Engineer. You must be comfortable tuning LLMs for structured outputs and complex classification tasks.
  • Academic Background: BS, MS, or PhD in Computer Science, Data Science, Computational Linguistics, or a related analytical field.
  • Technical Agility: Fast learner capable of mastering proprietary internal tools and interfaces (like the Goose API) with minimal supervision.
  • Data Fluency: Strong ability to identify error patterns and use SQL or data analytics tools to analyze model performance.
Preferred Skills
  • Familiarity with shadowbot disagreement tracking between humans and LLMs.
  • Hands-on experience with Chain-of-Thought (CoT) and few-shot learning.
  • Proven ability to draft high-level Launch Certification Documentation.
