This researcher will assist the research team in conducting soil sampling in the field and assess soil functions using multi-omics analyses. The major tasks will include but are not limited to:
- Quantify microbial functional genes using qPCR.
- Develop AI-driven bioinformatics pipeline and analyze multi-omics data.
- Perform soil sampling and experiment design.
- Measure soil properties—soil pH, moisture content, Inorganic N, etc.
- Soil incubation and activity measurement.
- Training undergrad and graduate students in the laboratory.
BASIC QUALIFICATIONS:
Applicants should have the following qualifications to be considered:
- PhD in microbial ecology/microbiology, and bioinformatics or related field.
- Experience in multi-omics pipeline development and analyses are required.
- Experience in wet lab: soil incubation, qPCR, DNA/RNA extraction.
- Evidence of scientific productivity in the form of peer-reviewed publications.
- Ability to take a leadership role for the project.
SALARY AND BENEFITS:
Salary is commensurate with experience. Health insurance benefits are provided. The appointment is for 1 year with the possibility of an additional year pending satisfactory progress.
APPLICATION DEADLINE:
This position will be open until it is filled.
APPLICATION:
Interested applicants should send (1) a cover letter detailing the applicant’s research experience and starting date availability, (2) curriculum vitae, and (3) name, telephone numbers and e-mail addresses of three professional references to Dr. Laibin Huang (laibin.huang@slu.edu). Please, include the following in the subject line of the e-mail: “Your Last Name - Postdoc Application.”

If accommodation is needed for completing the application and/or with the interviewing process, please contact Human Resources at 314-977-5847.
CRITICAL OR ESSENTIAL:
The postdoc hire is critical to the department’s research mission and important for supporting ongoing research in Dr Huang’s Microbial Ecology Lab. The primary focus of this role is to support ongoing research, establish lab protocols, and generate preliminary data for securing extramural funding. Below are the specific aspects related to this position:
a) Developing standard protocols for Molecular techniques. This will require different kinds of training skills, including field soil sampling and soil nutrients analyses, experimental design, gene clone, PCR and qPCR, sequence library preparation. These skills are critical for maintaining lab productivity and data integrity.
b) Data analyses: skills in bioinformatics and high-throughput data analyses (metagenomic/transcriptomic analysis). These are critical for interpreting complex datasets and translating them into publications for supporting grant proposals.
c) Mentoring and training graduate students: training the graduate students with these hands-on experiences and data analysis skills. This will strengthen the lab’s research output as well as the department’s mission of fostering high-quality training in graduate research.

Get Access To All JobsTips for Finding TN Visa Sponsorship as a Research Engineer
Align your credentials to TN engineer criteria
The TN visa engineer category requires a degree in engineering or a closely related field. A computer science or physics degree can qualify for research engineer roles, but you'll need documentation showing the field directly supports the position's technical scope.
Target labs with visa sponsorship experience
National laboratories, university-affiliated research centers, and large technology companies have recent visa filings and are experienced with work visa sponsorship, often hiring for roles that qualify for TN status. Focusing your applications on employers with this sponsorship background simplifies the process—they're already familiar with visa requirements and can move quickly with your support letter and port-of-entry application.
Get your support letter ready before your port of entry
Your employer must prepare a support letter before your TN application is submitted. Flag this requirement to your hiring manager during the offer stage, not after signing. For Canadian applicants, you'll present this letter at the U.S. port of entry; for Mexican applicants, it's submitted with your consulate application. The process typically moves quickly once documentation is ready.
Distinguish applied research from pure research in your offer letter
CBP officers evaluate whether your role fits the engineer definition, not a scientist or researcher category. Your offer letter should describe engineering methods, systems, or applied technical problem-solving rather than open-ended or theoretical research.
Use Migrate Mate to find TN-ready research engineer openings
Searching general job boards surfaces roles with no sponsorship pathway. Migrate Mate filters for employers actively offering TN visa sponsorship for research engineer positions, so you apply only where the visa pathway already exists.
Prepare a credential package before your first interview
Have your degree transcripts, a credential evaluation if your degree is from outside the U.S. or Canada, and a current employment verification letter ready before offers begin. Delays in gathering these documents are the most common bottleneck after an offer is extended.
Research Engineer TN Visa: Frequently Asked Questions
Does a research engineer role qualify for TN visa status?
Yes, if the position falls under the TN engineer category and requires a degree in engineering or a directly related technical field. Roles focused on applied R&D, systems development, or computational engineering typically qualify. Roles framed as pure scientific research may be assessed under the scientist category instead, so your offer letter's language matters.
How does TN compare to H-1B for research engineer positions?
TN has no lottery, no annual cap for Canadians, and can be approved at the border on the same day for Canadian citizens. H-1B visa requires entering a lottery with roughly a 25% selection rate and waiting months for processing. For research engineers who qualify under USMCA, TN is a faster and more predictable path to U.S. employment.
What documents does my employer need to sponsor my TN visa as a research engineer?
Your employer must prepare a support letter describing your engineering duties and qualifications, confirming that the role qualifies under the TN category for professionals. Canadian citizens present this support letter at a U.S. port of entry; Mexican citizens submit it as part of a visa application at a U.S. embassy or consulate.
Where can I find research engineer jobs that already offer TN visa sponsorship?
Migrate Mate is built specifically for Canadian and Mexican professionals seeking roles with active TN visa sponsorship. Rather than filtering through general postings where sponsorship availability is unclear, Migrate Mate surfaces research engineer positions from employers who have confirmed they will support the TN process.
Can I switch research engineer employers while on TN status?
Yes, but your TN status is tied to your current employer. You cannot begin working for a new employer until your new TN is approved. Your new employer must prepare a support letter and either support a new port-of-entry application for Canadians or a new consular application for Mexican citizens before your start date.
