Location: San Francisco; New York City Workplace: Hybrid ABOUT THE JOB We're looking for an experienced Global Mobility Lead to build and run the programs that help employees join, move, and work across borders. You will own our mobility policies, immigration casework, and vendor relationships, and partner with Legal, Finance, and People Ops to make cross-border moves clear, compliant, and well supported. WHAT YOU’LL OWN GLOBAL MOBILITY - Own the mobility policy suite end to end: relocation, permanent transfers, short-term and long-term international assignments, remote/cross-border work arrangements, and business travel thresholds. - Run individual mobility cases from scoping to landing: package design, cost estimates, immigration sequencing, tax and social-security implications, payroll setup, relocation logistics, and post-arrival support. - Manage employment-based immigration casework in partnership with outside counsel: H-1B (including cap-subject and change-of-employer/AC21 timing), L-1, TN, E-3, O-1, F-1 OPT/CPT, and employer-sponsored permanent residence. Own the internal timeline, the start-date reality check, and the manager/candidate communication. - Own daily immigration intake and case execution, including employer questionnaires, supporting documents, employment verification letters, signatures, counsel follow ups, and case closure. - Own right-to-work compliance across jurisdictions: I-9 and E-Verify in the US, Home Office share-code checks in the UK, and equivalent checks in our EU and other markets. - Decide and document the entity/employment model for each new market (direct entity, EOR, or non-resident payroll registration) with Finance and Legal. - Own our mobility vendor stack (immigration counsel, relocation, tax, EOR/global payroll): scope, SLAs, cost, and performance. - Model and track mobility cost, including sponsorship and premium-processing fees, so leadership can make go/no-go calls with real numbers, and obtain and document required approvals before committing sponsorship or spend DATA AND SYSTEMS - Build the tracking layer: mobility case pipeline, immigration deadlines and expirations, compensation comparisons, etc. - Stand up mobility dashboards: case volume, cycle time, cost per move, band penetration, offer-to-band variance, and equity-gap trend. - Write the employee-facing documentation so moves and pay decisions are predictable and explainable, not one-off negotiations. What we’re looking for REQUIRED - 6+ years of experience in global mobility, with real ownership of cross-border moves and immigration casework, not just vendor hand-offs. - Working fluency in US employment-based immigration and at least one other major jurisdiction’s work-authorization regime (UK, EU, or Canada). - Strong analytical skills: comfortable in spreadsheets and HRIS reporting, able to build a defensible model and explain the assumptions behind it. - Judgment about risk. You know when to escalate to Legal, when to flag classification or permanent-establishment exposure, and how to say no clearly. - Excellent written communication: you’ll draft policies, verification letters, offer rationales, and executive-facing recommendations. - Comfort with ambiguity, high volume, and shifting priorities.

QUALIFICATIONS - Pursuing a Bachelor's or Master’s degree in computer science, engineering, or another related field. Must graduate before December 2027. - Previous mobile internship experience. - Working towards a proficiency of one or more programming languages such as Kotlin, Java, Typescript, Node.js, Swift, Go, Python, or Rust. - You find large challenges exciting and enjoy discovering problems as much as solving them. - You are able to problem-solve and adapt to changing priorities in a fast-paced, dynamic environment. - This internship will take place from Jan - Apr and you will need to be able to work out of our SF or NY office during this time. SKILLS YOU'LL NEED TO BRING: - Thoughtful problem-solving: For you, problem-solving starts with a clear and accurate understanding of the context. You can decompose tricky problems and work towards a clean solution, by yourself or with teammates. You're comfortable asking for help when you get stuck. - Put users first: You think critically about the implications of what you're building, and how it shapes real people's lives. You understand that reach comes with responsibility for our impact—good and bad. - Not ideological about technology: To you, technologies and programming languages are about tradeoffs. You may be opinionated, but you're not ideological and can learn new technologies as you go. - Empathetic communication: You communicate nuanced ideas clearly, whether you're explaining technical decisions in writing or brainstorming in real time. In disagreements, you engage thoughtfully with other perspectives and compromise when needed. - Team player: For you, work isn't a solo endeavor.

Location: United States About Us Moongate is building the world's leading sound therapy app, helping people sleep better, get focused, and relieve stress. We're bootstrapped, profitable, and focused on scaling to eight-figure ARR while keeping the team small and nimble. The Role You'll own the growth and monetization engine for our app: our web funnels, activation, onboarding, pricing, paywalls, and win-backs. Moongate has strong product-market fit and a large, growing subscriber base. What we need now is someone who can turn that base into compounding revenue through relentless, data-driven experimentation. You'll be thinking strategically, but primarily hands-on: designing tests, building the campaigns and lifecycle journeys, shipping paywall and pricing changes, reading the results, and iterating. You'll work closely with the founders, head of marketing, and our engineering team, to build both growth features, but also to implement the tooling and systems that empower your role. Requirements You're a Fit If You have a demonstrable track record of driving measurable revenue growth through pricing, paywall, and lifecycle experimentation on a subscription product. You're as comfortable executing as strategizing: building the campaign, configuring the CRM flow, or shipping the paywall yourself. You have hands-on experience with subscription billing flows, like Apple IAP or Stripe. You've built and run CRM/lifecycle campaigns end-to-end. You have a strong mobile subscription/monetization background. You're a good writer with exceptional written English, able to internalize our brand voice and make it your own. You know how to leverage AI tools to increase your capacity and execute faster with a lean team. Benefits Why Moongate? No bureaucracy. You'll be making top-level decisions alongside the founders every day. Maximum impact. You'll directly own the revenue engine for an app with over 1 million downloads and 100,000 subscribers. High growth potential. We're aiming for 10x (100x!) growth. You'll directly contribute to that, and have a stake in it. Positive mission. Our goal is to improve people's wellness through sound therapy. We hear stories every week of the life changing impact Moongate has had on people's sleep habits, mental health, and overall wellbeing. In a world full of addictive, engagement-driven products, this is a rare opportunity to help promote wellness instead.
