Millions of domain experts on the platform are paid over $4 million per day to train frontier AI models. Mercor's APEX benchmark family measures AI's real-world impact on professional work. Mercor Enterprise brings this same infrastructure to Fortune 500 companies: helping companies capture how their best people actually work, translating that expertise directly back into agents.
Mercor is creating a new category of work where expertise powers AI advancement. Achieving this requires an ambitious, fast-paced and deeply committed team. You’ll work alongside researchers, operators, and AI companies at the forefront of shaping the systems that are redefining society. Mercor is a profitable Series C company valued at $10 billion. We work in-person five days a week in our San Francisco, NYC, or London offices.
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 Software Engineer
Align your resume to U.S. conventions
U.S. hiring managers expect a one- to two-page resume, not a multi-page CV. Lead with a technical skills summary listing your languages, frameworks, and cloud platforms, since these are the first things backend engineering recruiters filter on.
Target employers with LCA filing history
Search the DOL's Office of Foreign Labor Certification disclosure data to find companies that have filed LCAs for backend or software engineering roles. These employers already understand the process and are far less likely to withdraw an offer when sponsorship comes up.
Clarify E-3 specifics early in interviews
Many U.S. engineering hiring managers confuse the E-3 with the H-1B visa and assume a lottery is involved. Correcting this in the recruiter screen, by explaining the E-3 has no cap and no lottery, prevents the sponsorship conversation from stalling at the offer stage.
Confirm your degree satisfies specialty occupation
USCIS requires your bachelor's degree field to directly relate to backend software engineering. A computer science, software engineering, or information systems degree qualifies cleanly. If yours is in a different field, document how your coursework and work history bridge the gap.
Use Migrate Mate's E-3 filing service for paperwork
Once you have an offer, the LCA and DS-160 filings move quickly. Migrate Mate's E-3 filing service manages the entire process from LCA certification through consulate appointment, so you and your employer aren't coordinating government portals under deadline pressure.
Negotiate your start date around consulate wait times
E-3 visas are issued at Australian consulates in Sydney, Melbourne, and Perth, and appointment availability fluctuates. Build at least four to six weeks between your offer acceptance and proposed start date to absorb any scheduling delays without putting the role at risk.
E-3 Visa Backend Software Engineer: Frequently Asked Questions
How do I find backend software engineer jobs with E-3 sponsorship?
Migrate Mate is built specifically for Australian professionals searching for E-3 visa roles in the U.S. You can filter backend engineering positions by employers who have active sponsorship history, which removes the guesswork of approaching companies unfamiliar with the E-3. Most general job boards don't surface visa sponsorship data, so searching without that filter wastes 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 backend software engineering qualify as an E-3 specialty occupation?
Yes. Backend software engineering consistently meets the USCIS specialty occupation standard because the role normally requires at minimum a bachelor's degree in computer science, software engineering, or a directly related field. Job postings that list a relevant degree as required, rather than preferred, are the strongest fit. Roles described as general IT support or requiring any bachelor's degree are harder to support under E-3.
How does the E-3 compare to the H-1B for backend engineering roles?
The E-3 has no annual lottery and no numerical cap, so you can apply any time of year after receiving a job offer. The H-1B is subject to an annual lottery with a roughly 25 to 30 percent selection rate for most applicants. For an Australian backend engineer, the E-3 is the direct path, and there's no reason to pursue H-1B sponsorship when the E-3 is available.
What does my employer actually have to do to sponsor my E-3?
Your employer files a Labor Condition Application with the DOL certifying that your offered wage meets the prevailing wage for the role and location. That's the main employer obligation before your visa interview. The employer doesn't file a petition with USCIS for consular E-3 applications, which makes the process significantly lighter than H-1B sponsorship and a common reason engineers can move faster from offer to start date.
