The Senior iOS Developer is a hands‑on senior contributor to Esyasoft's iOS app, a key surface for our clients and end-users. The role combines high‑quality individual delivery with active mentorship of mid‑level iOS engineers and contribution to platform direction.

The role owns:

• Hands‑on delivery of features and improvements to Esyasoft's iOS app
• Quality, performance and reliability of iOS code
• Code review and mentoring of less senior iOS engineers (as required)
• Contribution to architectural decisions on the iOS codebase

Key Responsibilities & Areas of Ownership

A. iOS Development

• Champion SOLID principles, clean architecture and testable code
• Contribute to architectural decisions across the iOS codebase

C. Quality, Code Review and Releases

• Write well‑tested code (unit tests as standard); partner with the QA team on integration and UI test coverage where relevant
• Participate in code review with rigor
• Support release management — staged roll outs, monitoring, post‑release follow‑through

D. Cross‑Functional Collaboration

• Communicate clearly with non‑technical stakeholders including product and design — explain trade offs without losing them
• Work with backend and data teams to ensure any blockers or issues with APIs or data are resolved

E. Security, Data Privacy and Compliance

• Adhere to Esyasoft's data protection and security policies — Cyber Essentials, ISO 27001 and PCI‑DSS where relevant
• Embed secure‑by‑default patterns in iOS code — secure storage, key chain hygiene, certificate pinning, secrets management

F. Learning and Engineering Growth

• Keep up with the evolving iOS ecosystem — new APIs, framework updates, Apple platform changes
• Bring practical innovation into the team — prove value first, then adopt

Requirements

• Demonstrable senior‑level commercial experience as a native iOS developer
• Strong commercial experience with Swift and the modern iOS development stack (MVVM, SwiftUI, UIKit)
• Extensive experience of RESTful API and third‑party integration
• Experience of TDD, BDD or other code testing practices; understanding of data structures and algorithms

Desirable Skills & Experience

• Commercial experience with Apple MapKit or other mapping platforms; e‑commerce or payment gateways
• Experience with Combine, Swift Concurrency and SwiftUI
• Experience with automated UI testing (XCUITest, Snapshot Testing) and CI/CD pipelines

Key Attributes

• Curious — actively keeps up with iOS evolution; willing to experiment responsibly
• Pragmatic — values clarity and shipped quality over cleverness

• RESTful APIs, Firebase, Apple frameworks, mapping and payment integrations
