About the Role
As a Member of Technical Staff of talent experience, you'll own the shared backend architecture that underpins every user journey for talent network at Mercor.
Mercor's products—talent matching, assessment, expert workflows—are growing faster than any single team can architect for. You'll define the technical direction of the systems they all depend on: core services, data models, APIs, and infrastructure patterns that must scale with a network of tens of thousands of experts and the demands of the world's leading AI labs. You'll set the standards that dozens of engineers build on, pay down the architectural decisions that no longer fit, and make the ones that will still be right three years from now.
This is a hands-on technical leadership role, not a management role. You'll write code, review the designs that matter most, and act as the connective tissue between product teams—partnering directly with engineering leadership to shape how the organization builds.
- Own the architecture of Mercor's shared backend systems—core services, data models, APIs, and cross-product infrastructure.
- Define and drive the long-term technical strategy for backend architecture across the organization.
- Design systems for scale, reliability, and evolvability, and lead the highest-stakes technical decisions and design reviews.
- Identify and pay down architectural debt that slows product teams, and lead complex cross-team migrations.
- Establish backend engineering standards, patterns, and best practices adopted across all product teams.
- Stay hands-on: prototype critical systems, ship production code, and unblock teams on their hardest technical problems.
- Mentor senior engineers and raise the technical bar across the engineering organization.
- Partner with engineering and product leadership on build-vs-buy decisions, platform investments, and technical hiring.
What We're Looking For
- 8+ years of professional backend engineering experience, including 3+ years operating at a Senior level or above.
- Deep expertise in distributed systems, service architecture, data modeling, and API design at scale.
- A track record of owning architecture across multiple teams or an entire organization—and of decisions that aged well.
- Experience leading large, complex technical migrations in production without stopping the business.
- Strong opinions, loosely held: you drive alignment through technical judgment and clear writing, not authority.
- Fluent in using modern AI development tools (e.g. Cursor, Claude Code, GitHub Copilot, or similar) to improve engineering productivity.
- Experience mentoring senior engineers and raising the technical bar across an organization.
- Excellent communication skills—able to make complex tradeoffs legible to both engineers and leadership.
- High ownership, pragmatism, and a bias toward shipping.
Why Mercor
- Impact: Own the architecture that every Mercor product is built on, at a company scaling faster than almost any in its category.
- Ownership: Organization-wide technical scope with a direct line to engineering leadership and real authority over technical direction.
- Learning: Work alongside world-class engineers, product leaders, and AI researchers building products at the frontier of AI.
- Growth: Shape the engineering organization itself—its standards, its architecture, and its next generation of technical leaders.
Benefits
- Generous equity grant vested over 4 years
- A $20K relocation bonus (if moving to the Bay Area)
- A $10K housing bonus (if you live within 0.5 miles of our office)
- A $1.5K monthly stipend for meals
- Free Equinox membership
- Health insurance
Compensation Range: $250K - $500K

Get Access To All JobsTips for Finding E-3 Visa Sponsorship as a Backend Engineer
Align your credentials to specialty occupation standards
USCIS evaluates whether your specific degree field matches the Backend Engineer role. A computer science or software engineering degree is the cleanest fit. If yours is in a different field, document how your coursework maps to the technical requirements of the position.
Target employers with active DOL LCA filings
Search the DOL's Office of Foreign Labor Certification disclosure data for companies that have filed LCAs for backend or software engineering roles. Employers already familiar with the LCA process move faster and are less likely to withdraw offers due to paperwork uncertainty.
Clarify sponsorship scope before accepting an offer
Some employers will cover the E-3 visa LCA filing but expect you to fund the consular visa fee yourself. Confirm in writing which costs each party covers before you sign, so there are no surprises when the government fees come due.
Use Migrate Mate's E-3 filing service for end-to-end support
Once you have an offer, Migrate Mate's E-3 filing service handles the LCA submission with DOL, prepares your visa paperwork, and guides you through the consulate appointment in Sydney, Melbourne, or Perth, reducing the risk of documentation errors that delay your start date.
Convert contractor roles into E-3 eligible positions
Some backend roles are initially posted as contractor or freelance arrangements, which don't meet the E-3 employer-employee relationship requirement. Ask the hiring team whether the role can be structured as direct employment before you invest time in interviews.
Prepare for E-Verify enrollment requirements
Federal contractors and companies above certain size thresholds must enroll in E-Verify when hiring E-3 workers. Confirm your prospective employer is enrolled or willing to enroll before the LCA is filed, since unenrolled employers can't complete the I-9 process legally.
E-3 Visa Backend Engineer: Frequently Asked Questions
How do I find Backend Engineer jobs that offer E-3 visa sponsorship?
Migrate Mate is built specifically for Australian professionals searching for U.S. roles with E-3 sponsorship. You can filter by job title, location, and employer type to surface companies that have a demonstrated history of hiring on the E-3. General job platforms don't surface sponsorship intent reliably, so a targeted search saves significant time.
How much does it cost to get an E-3 visa?
Migrate Mate's E-3 filing service covers the entire process for $499, including the Labor Condition Application, visa document preparation, and consulate appointment guidance. Traditional immigration lawyers charge $2,000–$5,000+ for the same work. The E-3 has less paperwork than most work visas, so paying thousands for legal help is usually unnecessary.
Does a Backend Engineer role qualify as a specialty occupation for the E-3 visa?
Yes, provided the position genuinely requires a bachelor's degree or higher in a specific technical field such as computer science or software engineering. If the job description lists the degree as preferred rather than required, USCIS may not classify it as a specialty occupation. Ask the employer to revise the job description before the LCA is filed to avoid a Request for Evidence later.
How does the E-3 compare to the H-1B for Backend Engineers?
The E-3 has no annual lottery and no numerical cap that affects availability. For Australian Backend Engineers, this means you can apply and start as soon as an employer files the LCA and you clear your consulate interview, rather than waiting up to a year for an October 1 start date under the H-1B cap. The trade-off is exclusivity: only Australian nationals qualify.
Can I switch employers or change projects while on an E-3 as a Backend Engineer?
You can change employers, but each new employer must file a fresh LCA with DOL before you start work. Moving to a different team within the same company is generally fine without a new filing, unless your job duties change substantially. You can begin work with a new employer as soon as the LCA is certified, without waiting for a new visa stamp if your current E-3 is still valid.
