Full-time | Annual salary: $90,000 - $135,000

Compensation varies based on location, experience and qualifications.

Put your tax expertise to work changing an entire industry.

You've spent years learning how to solve complicated tax problems. At MiraFlores AI, that expertise can shape the technology that solves them next.

Our ambition is to make sophisticated financial expertise accessible to everyone. Born inside GreenGrowth CPAs, MiraFlores brings the experience of a working tax practice into AI product development. We're building toward a lasting change in financial services, starting with how taxes are prepared and understood.

As our Global Mobility Tax Manager, you'll lead complex client engagements and work with product and engineering teams to improve the tools behind them. A difficult case, a recurring error or a better review process can become the starting point for a product improvement that helps many more people.

What you will own

Manage and review U.S. individual tax compliance for expatriates, inbound and outbound assignees, and internationally mobile employees.

Advise clients on cross-border tax matters, global mobility programs, tax equalization, international assignments and related payroll and compliance requirements.

Research complex tax questions, document your conclusions and review returns and workpapers for accuracy and completeness.

Build trusted client relationships, explain complicated issues clearly and manage multiple engagements through delivery.

Translate recurring client problems into clear product requirements, tax logic and workflows with our product and engineering teams.

Help test AI-generated work against source documents and authoritative guidance. Develop realistic cases that expose errors and guide improvements.

Identify repetitive manual work and help redesign how it gets done, with accuracy and client outcomes guiding every change.

What you bring

CPA or EA designation and 5+ years of experience in Global Mobility Tax.

Strong knowledge of U.S. individual taxation and international tax concepts, with sound judgment on complex technical questions.

Experience managing client relationships and multiple engagements, supported by excellent written and verbal communication.

Curiosity about AI and a willingness to learn new tools, question their output and help make them better.

The initiative to spot a problem, propose a practical solution and follow through on it.

How we work

We give people room to make decisions and expect them to take responsibility for the results. Our values show up in the work every day.

Own the Outcome.

Stay with a client issue or product problem until it is resolved. Measure your contribution by the difference it makes.

Ship, Test, Learn.

Put improvements into practice, check the results and use what you learn. In tax, that includes rigorous review before clients rely on the work.

Builder First.

Notice where a process breaks down and help create a better one. Bring your ideas and take an active role in making them real.

Grow or Go.

Keep developing your skills and raising your standards. Be open to direct feedback and turn it into better work.

Why this role is worth your ambition

You'll bring a tax expert's perspective directly into product decisions. The patterns you recognize in client work can shape what we automate, how we test it and where professional judgment matters most.

You'll build experience at the intersection of global mobility tax and AI, and help turn your ideas into tools other professionals can use. Your influence can extend across the returns, teams and clients those tools serve.

The pace is fast, the problems are demanding and priorities evolve as we learn. You'll thrive here if you enjoy taking initiative and seeing an idea through to a useful result.
