App Developer is needed in Valencia, Spain.

Client: AgileEngine

Location: Valencia, V, es

Contract: Contract

Job Description

AgileEngine is seeking a Lead iOS Engineer to join a platform-focused team. In this role, you will contribute hands-on to iOS implementation while raising the technical standards across architecture, quality practices, and AI-assisted delivery. Key responsibilities include designing and maintaining MVVM-based iOS architecture, integrating third-party SDKs and cloud-connected platform functionality, and implementing appropriate testing strategies for the team. The position requires strong ownership in a high-ambiguity environment, transforming unclear requirements into clear technical plans with minimal supervision.

Requirements

MUST HAVES

• 5+ years of experience as an iOS engineer with strong hands-on Swift/iOS implementation experience.
• Strong hands-on experience with modern Swift Concurrency (async/await, Actors, structured concurrency) in production applications.
• Strong experience in building and shipping production iOS applications at scale.
• Strong knowledge of MVVM and modern architectures such as TCA, Clean Architecture, or similar.
• Proven experience leading technical discussions, driving architecture decisions, and influencing engineering best practices across a team.
• Experience integrating third-party SDKs in production mobile applications.
• Strong understanding of networking, API integration, error handling, and mobile-backend interaction patterns.
• Experience with Cloud Code or comparable cloud-connected mobile/platform functionality.
• Strong experience defining testing strategy, selecting testing frameworks and quality practices, and determining appropriate unit, integration, UI, snapshot, contract, or other test coverage.
• Experience using AI-assisted engineering tools to improve implementation, debugging, refactoring, testing, documentation, and development workflows.
• Strong ownership mindset with the ability to operate independently, communicate progress clearly, and proactively surface risks and blockers across time zones.
• Upper-intermediate English level.

NICE TO HAVES

• Experience with modular iOS architecture in large-scale consumer applications.
• Experience defining or improving team-level testing strategy, not just contributing individual tests.
• Experience working on platform teams or shared mobile foundations used by multiple product teams.
• Experience with cloud-connected mobile features, backend-for-frontend patterns, or services that require close mobile/backend coordination.
• Prior experience in high-ambiguity environments where requirements need discovery, validation, and technical shaping before implementation.
• Practical experience using AI tools to improve engineering workflows while preserving code quality, security, and authenticity.
