What this hire really comes down to

The Cross-Platform Mobile Developer role is centered on building unified experiences that maintain high performance while targeting multiple operating systems from a single codebase. We need engineers who are not merely wrappers around platform APIs but who deeply understand the underlying differences between platforms and can extend their reach using native modules when the standard framework falls short. This requires a balanced perspective on balancing development velocity with the need for high-quality, native-feeling interactions.

Your hire will be operating within a technical scope that requires mastery of reactive programming and efficient bridge communication to ensure the UI remains fluid. Our sectors often demand deep integration with hardware sensors or proprietary backend protocols, meaning the candidate's ability to write and maintain native Swift or Kotlin modules within a cross-platform environment is essential. We look for engineers who approach the trade-offs between shared and platform-specific code with a clear, architectural focus on long-term maintainability and system stability.

What we check before you see anyone

Production Experience
We look for a demonstrated history of shipping and maintaining cross-platform applications in a live, high-traffic environment. You must explain how you handled the nuances of different OS behaviors and versioning. Candidates who have only worked on small hobby projects or lack a history of work through app review and production support challenges are typically not prepared for the responsibilities of this role.
Native Module Development
This check assesses the candidate's proficiency in writing platform-specific code that bridges back to the shared core. We look for concrete examples of when you had to drop into Swift or Kotlin to overcome framework limitations. You must show an understanding of the performance overhead and the complexity of managing state across these boundaries. Inability to explain bridge-related debugging is a disqualifier.
CI and CD Pipelines
You must demonstrate expertise in automating build, test, and release workflows using tools like Fastlane or equivalent cloud-based distribution services. We look for experience with environment management and automating the deployment process for multiple platforms simultaneously. If you have never set up or maintained a pipeline, or rely solely on manual builds, you lack the necessary operational maturity for our engineering teams.
Performance Monitoring
We evaluate the candidate's ability to measure and optimize the performance of a shared codebase. You should explain your strategies for identifying rendering issues or memory leaks that occur inside the abstraction layers. Candidates must show they understand how to use platform-native profiling tools even when the primary development happens in a framework, as a reliance on generic web-like debugging is insufficient.
Architectural Logic
We examine how you organize a shared codebase to ensure separation of concerns between business logic and UI components. We want to see how you manage state effectively and implement clean architectural patterns that facilitate testing. An inability to discuss the drawbacks of your chosen architecture, or a lack of understanding regarding how the framework affects data flow, is a sign of shallow expertise.
State Management Competency
This check focuses on how you maintain data consistency in a reactive programming environment. We ask about your experience with Redux-like patterns or modern reactive streams. You should describe how you manage complex asynchronous events without introducing race conditions or UI flicker. Candidates who struggle to articulate their state management strategy for large applications are often unsuited for the complex data requirements of our systems.

Where we find them

We source from product-focused agencies and fast-moving startups where the mandate is to deliver high-quality features simultaneously on both mobile platforms. Our ideal candidates are those who have contributed to the evolution of the cross-platform ecosystem by developing reusable modules or addressing upstream framework issues. We target individuals who value the hybrid approach but are not afraid to dive into the platform-native code to optimize the user experience or add custom features.

Our sourcing also includes professionals who have successfully transitioned from native-only development into cross-platform roles, as these individuals bring a deeper understanding of the platform underpinnings. We look for developers who have demonstrated resilience in the face of framework changes and who actively advocate for testing and performance best practices. By focusing on those who have work through the complexities of integrating shared code with C plus plus or Rust backends, we find the talent necessary for our challenging technical market.

Mistakes we see

Treating a credential as the answer
Do not let production experience become a keyword filter. Candidates who have only worked on small hobby projects or lack a history of work through app review and production support challenges are typically not prepared for the responsibilities of this role.
Leaving the actual scope out
Put the responsibility for native module development in the brief, including who helps the hire and who decides. This check assesses the candidate's proficiency in writing platform-specific code that bridges back to the shared core.
Waiting until the offer to discuss the work
Discuss what the person will own in ci and cd pipelines before the interview loop. If you have never set up or maintained a pipeline, or rely solely on manual builds, you lack the necessary operational maturity for our engineering teams.

The search in three steps

Agree the brief
The process begins with a technical review of your architecture and bridge management strategies. We examine how you approach shared versus native code and how you address the limitations of the abstraction layers. We expect candidates to share a portfolio of work where they have work through specific platform hurdles. This phase helps us gauge your technical maturity and the candidate's ability to make architectural decisions that favor long-term system stability over short-term implementation gains.
Find and speak with people
The second interview stage involves a deep dive into your operational capabilities and team integration. We explore how you handle debugging complex cross-platform issues that involve multiple layers of the stack and how you collaborate with developers working in other domains. We prioritize those who demonstrate clear communication and an ability to mentor junior members. This stage concludes with a collaborative session on designing a feature that requires both shared logic and custom platform implementation to ensure high-performance execution.
Introduce the people who fit
We send a written brief on each person you meet, including why the work fits and the questions still worth asking about state management competency. You decide who to interview. We help with the conversations through the offer.

Questions about this search

When will we see a shortlist?

We agree the search plan after checking your requirements for production experience and native module development, rather than promising a date before the brief is clear. We look for a demonstrated history of shipping and maintaining cross-platform applications in a live, high-traffic environment.

What if a candidate gets a counteroffer?

We ask what would make someone leave work involving production experience, and what could make them stay. Before you invest in interviews, we discuss whether your offer changes the problem they want to leave, including the responsibility for state management competency.

Should this role be remote or on site?

Experience with production experience and native module development does not settle the location question. Tell us what access and supervision the work needs, including who owns decisions about state management competency, so we approach people who can accept the arrangement.

How will you check fit before we interview?

We look for a demonstrated history of shipping and maintaining cross-platform applications in a live, high-traffic environment. You must explain how you handled the nuances of different OS behaviors and versioning. This check assesses the candidate's proficiency in writing platform-specific code that bridges back to the shared core.

How does the fee work?

No upfront fee. You pay only if you hire. Agree the fee and the responsibilities covering production experience and native module development in the recruiting agreement before the search proceeds.

What if the hire does not work out?

We offer a candidate replacement guarantee on standard search agreements. The applicable period and exact terms are set out in the signed client recruiting agreement.
