About the Role
We’re looking for someone who wants to bring a full-stack perspective to data. As a Software Engineer supporting our Data function, you will be responsible for creating and maintaining pipelines that enable our Data Science, Engineering, and Product teams, and the wider Mercor organization.
Your focus will be on data reliability, availability, and timeliness, with a focus on collaboration (and significant operational crossover with) our Data Science team and the many partner functions.

- Implementing scalable, fault-tolerant data workflows with Fivetran, dbt, SQL, and Python.
- Partnering with engineers, data scientists, and business stakeholders to ensure data availability, accuracy, and usability.
- Owning data quality and reliability across the stack, from ingestion through to consumption.
- Continuously improving pipeline performance, monitoring, and scalability.
What We’re Looking For
- Proven experience in data engineering, with strong knowledge of SQL, Python, and modern data stack tools (Fivetran, dbt, Snowflake or similar).
- Experience building and maintaining large-scale ETL/ELT pipelines across heterogeneous sources (databases, analytics platforms, SaaS tools).
- Strong understanding of data modeling, schema design, and transformation best practices.
- Familiarity with data governance, monitoring, and quality assurance.
- Comfort working cross-functionally with engineering, product, and operations teams.
- Bonus: prior experience supporting machine learning workflows or analytics platforms.
Why Mercor
- Impact: Your work powers how the world’s leading AI labs train and test their models.
- Learning: Get early insights into frontier model capabilities months before the market.
- Growth: Work on both infrastructure and research-adjacent projects with fast paths to ownership.

Get Access To All JobsTips for Finding MERCOR E-3 Visa Sponsorship Jobs USA
Align your degree to MERCOR's technical roles
MERCOR's E-3 roles in AI and software require a specialty occupation match between your degree field and the job. A computer science or engineering degree tied directly to the posted role strengthens your application significantly more than a general STEM background.
Target roles with LCA filing history
Before applying, use Migrate Mate to check which MERCOR job categories have active Labor Condition Application filings, so you can prioritize roles where the E-3 sponsorship pathway is already established rather than negotiating it from scratch.
Confirm MERCOR's E-Verify enrollment before your interview
E-3 employers must be enrolled in E-Verify to sponsor the visa. Confirm this during your hiring process rather than after an offer lands, since it affects how quickly your LCA and visa paperwork can move through DOL.
Prepare a prevailing wage crosscheck for your role
Use the OFLC Wage Search to look up the prevailing wage for your specific job title and MERCOR's location before negotiating salary. Your offer must meet or exceed this figure for the LCA to be certified by DOL.
Clarify the filing ownership in your offer stage
At MERCOR, confirm whether the company files the LCA directly or routes it through external immigration counsel. Knowing who owns each step of the E-3 filing process helps you set realistic start-date expectations during the offer negotiation.
Map your occupation to the right O*NET code
MERCOR's AI and software roles can span multiple occupation categories. Cross-referencing your actual job duties against O*NET ensures your specialty occupation classification accurately reflects what you'll be doing, reducing the risk of an LCA mismatch.
MERCOR E-3 Visa Sponsorship: Frequently Asked Questions
Does MERCOR sponsor E-3 visas?
Yes, MERCOR sponsors E-3 visas for eligible Australian nationals in qualifying specialty occupation roles. The company's hiring activity in technology and software means E-3 sponsorship is primarily available for technical positions such as engineering, AI research, and product development. Confirm sponsorship availability directly with MERCOR's recruiting team during the interview process.
Which roles at MERCOR typically qualify for E-3 sponsorship?
E-3 sponsorship at MERCOR is most commonly attached to roles requiring a bachelor's degree or higher in a directly related technical field. Software engineering, AI and machine learning, and product roles are the most likely candidates. Roles without a clear degree-to-job-title connection are harder to qualify as specialty occupations under USCIS standards.
How do I navigate the E-3 application process at MERCOR?
Once MERCOR extends an offer, the employer files a Labor Condition Application with DOL, which must be certified before your visa application. You then apply directly at a U.S. consulate in Australia with the certified LCA, your offer letter, and supporting credentials. USCIS is not involved in consular E-3 applications, so there's no petition waiting period.
How long does E-3 sponsorship take at MERCOR?
DOL typically certifies an LCA within seven business days. After that, your consulate appointment wait time drives the overall timeline, which varies by location and season. Most applicants in Sydney or Melbourne complete the full process within four to eight weeks of receiving a certified LCA from MERCOR's team.
How do I find E-3 jobs at MERCOR and confirm sponsorship?
Migrate Mate surfaces roles at employers with verified E-3 LCA filing history, making it easier to identify MERCOR positions where sponsorship is already in motion. When you apply directly, ask the recruiter explicitly whether the role is approved for E-3 sponsorship, since not every open position at MERCOR will have an active LCA on file.
What is the prevailing wage for E-3 sponsorship at MERCOR?
E-3 employers must pay at least the prevailing wage, determined when they file a Labor Condition Application with the Department of Labor. The rate is based on the role, location, and experience level, ensuring Australian hires are paid comparably to U.S. workers in the same position. You can look up prevailing wage rates for any occupation and location using the DOL's OFLC Wage Search tool.
