Molecular Biology Sequence Design Expert

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We help experienced contributors consolidate work, track projects, and grow a durable freelance career focused on the human side of AI.

OpenTrain AI is the hiring organization for this role. We run specialist, short-start projects that connect subject-matter experts with tasks that directly improve how AI systems reason about real-world scientific problems.

Why AI training in the life sciences matters

AI models learn from curated, expert-created examples. In the life sciences, that means high-quality sequence designs, rationale, and review from people who understand experimental constraints and biological reasoning.

Contributors do remote, flexible work that shapes how future scientific tools behave. This project gives you the chance to embed rigorous design practices into model training data used across research and applied biology.

The role

You will serve as a Molecular Biology Sequence Design Expert focused on designing and reviewing DNA and RNA constructs used as training examples. The work centers on creating accurate solutions and evaluating model outputs for correctness and reasoning.

This is a contract, part-time role starting with an initial cohort of roughly 50–100 design tasks and the possibility of extension based on project needs and performance.

What you'll do

• Design and review DNA and RNA sequence constructs (primers, plasmids, RNAs, repair templates) prior to experiments.
• Author clear, well-documented expert solutions that serve as ground truth for model training.
• Evaluate AI-generated outputs against expert solutions and provide written feedback on correctness, rigor, and reasoning.
• Collaborate with other subject-matter experts to maintain consistency and quality across the training set.
• Complete an initial set of approximately 50–100 design tasks with careful documentation and justification for each decision.

Minimum requirements

• Hands-on experience designing nucleic-acid sequences for experimental use (primers, plasmids, RNAs, repair templates).
• Current practice or recent practice as a molecular biologist.
• Ability to write accurate, reproducible ground-truth scientific solutions and justify design choices in writing.
• Strong judgment for evaluating AI outputs on correctness and reasoning.
• Able to work 20+ hours per week as a contractor; must be located in the United Kingdom and fluent in English.

Preferred qualifications

• Advanced degree (MS, PhD) in molecular biology, genetics, biochemistry, synthetic biology, bioengineering, or a related life-science field is strongly preferred.
• Peer-reviewed publication record in respected life-science venues (Nature, bioRxiv, CSHL Press, eLife, or similar).
• Experience contributing expert feedback on technical or scientific work and familiarity with construct design workflows.

Logistics, pay, and format

Employment type: Contract, part-time. Time commitment: 20+ hours per week to start. Location: United Kingdom only; English required.

Compensation: USD $70–$105 per hour (rate band provided in posting). Work is remote and asynchronous; tasks are document-style (designs and evaluations). Labeling task types include evaluation/rating and text-generation.

How the project works and how to apply

OpenTrain projects begin with a defined task set, written guidelines, and example solutions. You will receive instructions and collaborate with other experts on quality and consistency.

To apply, create a free OpenTrain account, complete your profile, and submit your application for this role. Applications should highlight hands-on sequence-design experience, relevant publications, and availability for a 20+ hr/week contractor engagement.
