Are you an experienced React Native developer looking for a high-level mobile engineering opportunity that can be performed remotely? American IT Systems is recruiting a Mobile Engineer (React Native) for a role focused on building a high-performance cryptocurrency trading application from the ground up.
The position is designed for a senior mobile engineer who can take ownership of the application’s architecture, development and production reliability. The successful candidate will work closely with the founding team and help take the product from its earliest development stage through launch and rapid growth.
The role is fully remote, offers flexibility across time zones and has a salary range of $200,000 to $300,000, with the possibility of a higher offer for an exceptional candidate. Visa sponsorship may also be considered for outstanding applicants.
Job Overview
- Position: Mobile Engineer (React Native)
- Employer: American IT Systems
- Company/product: Arcade
- Location: Germany
- Work arrangement: Fully remote
- Experience: 6+ years in mobile engineering
- Seniority: Approximately 6–15 years of experience
- Salary: $200,000–$300,000
- Higher compensation: Possible for exceptional candidates
- Visa sponsorship: Considered for outstanding applicants
- Preferred time zones: North America and Europe
- Eastern Time Zone: Preferred
- Application type: Quick Apply
The position is particularly suited to an experienced engineer who has previously taken a consumer mobile product from an early stage through significant user growth.
About the Company
Arcade is developing a high-performance mobile application designed for cryptocurrency trading, with a particular focus on users who require fast execution and a smooth trading experience.
The company is self-funded and intends to build and scale the product rapidly. Its founding team has previous experience in the cryptocurrency sector, including building and scaling a decentralized exchange.
According to the vacancy, the founders previously grew an earlier product to $5.4 million in revenue during its first year with a team of just two people.
The new product is being built with an emphasis on speed, reliability and the ability to support substantial trading activity.
About the Mobile Engineer Role
This is not a conventional mobile development position where an engineer joins an established application and works on a narrowly defined part of the product.
The successful candidate will be the founding mobile engineer and will have responsibility for creating the application’s technical foundation.
You will work alongside the founder and a dedicated UI/UX designer while making important architectural decisions about how the application should be built and scaled.
The position requires someone who can operate independently, move quickly and make sound technical decisions without relying on a large engineering department.
Key Responsibilities
The successful candidate will be responsible for designing and developing the mobile application from its earliest stage.
Main duties include:
- Architecting the complete React Native application
- Establishing the technical foundation for the product
- Making core decisions about application architecture
- Building the mobile trading experience
- Developing spot and perpetual trading functionality
- Optimizing the application for speed and low latency
- Taking the product from development to the App Store
- Working closely with the founder and UI/UX designer
- Building features from initial concept through production
- Preparing the application to support rapid user growth
- Maintaining production reliability
- Investigating and fixing critical issues
- Automating release and deployment processes
- Monitoring application performance
- Ensuring the application remains responsive as usage increases
The company expects the application to eventually handle between 25,000 and 50,000 or more daily active users, alongside more than $100 million in daily trading volume.
Required Experience
Candidates should have at least six years of mobile engineering experience.
The employer is particularly interested in professionals who have worked in startup environments or were involved in developing major financial products during their early stages.
Experience building a product from zero to one is especially important. Applicants should be able to demonstrate that they have personally taken responsibility for significant features or an entire application rather than only working on small components within a large organization.
Experience with consumer-facing mobile applications is also important.
React Native and Technical Requirements
Strong React Native experience is essential for this position.
Candidates should have experience designing and building React Native applications from scratch using TypeScript.
The technology stack mentioned for the role includes:
- React Native
- TypeScript
- Expo
- Reanimated
- Skia
- Swift
- Kotlin
- Privy
- viem
- Solana
- Hyperliquid SDK
- PostHog
- Sentry
Experience with Swift or Kotlin is considered an advantage, although the primary requirement is strong React Native expertise.
Applicants with experience across both mobile development and Web3 technologies may be particularly relevant to the product being developed.
Experience That Could Make You a Strong Match
The employer is looking for evidence that a candidate can independently take ownership of a complex mobile product.
Relevant experience includes:
- Building a consumer mobile application from scratch
- Scaling an application to more than one million users
- Developing financial, brokerage, wallet or cryptocurrency applications
- Working with mobile trading products
- Building zero-to-one features
- Designing application architecture independently
- Working in an early-stage startup
- Operating as a founder or founding engineer
- Developing high-performance React Native applications
- Working with Web3 technologies
- Building applications where speed and reliability are critical
Candidates should emphasize projects where they were responsible for major technical decisions rather than simply contributing to an established system.
What the Employer Is Looking For
The ideal candidate should be comfortable working in a fast-moving environment where there is significant responsibility and relatively little bureaucracy.
The company wants an engineer who can take a product idea, determine the technical approach and turn it into a functioning mobile application.
A strong record of delivering substantial work is important. The role also requires someone who is comfortable dealing with difficult technical problems and taking ownership when production issues arise.
Startup experience can therefore be particularly valuable for this position.
Visa Sponsorship and Remote Work
The vacancy states that the position is fully remote and allows flexibility around working time zones.
Visa sponsorship is considered for outstanding applicants.
This is different from a vacancy that guarantees sponsorship for every international applicant. Candidates outside Germany should therefore treat visa support as a possibility rather than an automatic benefit.
The employer’s selection decision will depend on the candidate’s experience, technical ability and overall suitability for the role. Any immigration process would also remain subject to the applicable requirements of the country involved.
Candidates interested in relocating should confirm the available immigration arrangements directly with the employer before making plans.
Salary and Compensation
The advertised salary range is $200,000 to $300,000.
The vacancy also states that higher offers may be possible for exceptional candidates.
Given the seniority of the position and the level of technical ownership involved, applicants should be prepared to discuss their salary expectations during the recruitment process.
The application process specifically asks candidates about their expected compensation.
Who Should Apply?
This position is most appropriate for an experienced mobile engineer rather than someone beginning their career.
A strong candidate would typically have:
- At least six years of mobile engineering experience
- Advanced React Native knowledge
- Strong TypeScript skills
- Experience building applications from zero
- Experience with consumer mobile products
- A background in startup environments or early-stage product development
- Experience handling significant user growth
- Strong understanding of mobile application architecture
- Ability to work independently
- Familiarity with Web3 or financial technology
Candidates with only narrow optimization experience within very large technology companies may not match the type of background the employer is seeking.
CV/Resume Tips for This Position
A generic software engineering CV is unlikely to show your strongest qualifications for this particular role.
Your resume should focus heavily on React Native, mobile architecture and products you have personally helped build.
Start with your most relevant mobile engineering experience. If you have created an application from scratch, explain your responsibilities from the initial architecture through deployment.
If you have worked on a product that reached hundreds of thousands or millions of users, include that achievement.
For example, instead of writing:
“Worked on a React Native application.”
A stronger version would be:
“Architected and launched a React Native consumer application that scaled to more than 1 million users.”
Only include figures that accurately represent your work.
If you have experience with cryptocurrency, brokerage platforms, digital wallets, financial applications or trading systems, make those projects easy to find.
Your technical skills section should also clearly identify React Native and TypeScript before listing supporting technologies.
Recommended CV Skills Section
Depending on your actual experience, relevant skills could include:
- React Native
- TypeScript
- Expo
- JavaScript
- Mobile application architecture
- iOS development
- Android development
- Swift
- Kotlin
- Reanimated
- Skia
- Web3 development
- Solana
- viem
- Privy
- Hyperliquid
- Application performance optimization
- Mobile security
- CI/CD
- Sentry
- PostHog
Do not add technologies simply because they appear in the vacancy. Only list tools you have genuinely used.
Interview Process
The recruitment process is expected to move quickly because the company wants to scale the product without creating major technical problems later in development.
Candidates can expect several stages, including:
- An initial conversation with the founder
- A system design interview
- A coding session or take-home technical assessment
The system design stage is likely to be particularly important because the role involves designing the application’s architecture from the beginning.
Applicants should be prepared to explain how they would build a high-performance mobile trading application and how they would prepare it for substantial user and transaction growth.
Why the Role Is Different
The position gives the successful engineer unusually broad ownership over the mobile product.
Rather than joining a large team with an established architecture, the founding mobile engineer will be responsible for many of the decisions that determine how the application operates.
This includes choosing appropriate technical approaches, building core features, preparing the application for release and maintaining the product after launch.
For an engineer who enjoys startup environments and significant technical responsibility, the position offers the chance to have a direct influence on the product’s development.
How to Apply
The vacancy is listed as a Quick Apply opportunity for the Mobile Engineer (React Native) position.
Candidates should carefully review the complete vacancy and submit a CV that clearly demonstrates their mobile engineering experience.
During the application process, candidates should also be prepared to answer questions about salary expectations and their current interest in exploring new opportunities.
Because this is a senior position, applicants should make their most relevant achievements immediately visible rather than relying on a long list of general programming skills.
Important Information for International Applicants
International candidates should pay particular attention to the wording around immigration assistance.
The vacancy says visa sponsorship is considered for outstanding applicants. This does not mean sponsorship is guaranteed for everyone who applies.
Candidates outside Germany should therefore confirm whether the employer can support their particular immigration circumstances before accepting an offer or making relocation arrangements.
The remote nature of the position also means applicants should clarify where they would be legally employed and whether relocation to Germany is actually required or simply one possible arrangement.
