Senior AI Applied Software Engineer (iOS)
Senior iOS-focused engineer at Backbase designing, building, and evolving the enterprise Mobile Platform behind its digital banking software. Day to day: native iOS work (Swift, SwiftUI, UIKit, optionally Android/Kotlin), leading features end-to-end, and using AI coding agents across mobile, APIs, and CI/CD while mentoring peers.

Skills
Must have
- 5–7+ years of professional software engineering experience, operating at senior level
- Deep production expertise in native iOS: Swift, SwiftUI, UIKit, structured concurrency, Apple frameworks, Xcode, iOS build and release lifecycle
- Designed scalable mobile architectures using patterns such as MVI, MVVM, VIPER, or Clean Architecture
- Experience building modular applications, reusable libraries, frameworks, or SDKs with stable, well-designed APIs
- Strong in automated testing, debugging, profiling, CI/CD, release automation, and mobile non-functional requirements
- Hands-on experience using AI coding assistants or agents in production software delivery, with demonstrable outcomes
- Understanding of limitations and risks of agentic development and use of verification and human review
- Willing and able to work across both mobile platforms; depth in one plus evidence of cross-platform contribution is sufficient
- Effective English communication in an international, multidisciplinary environment
Nice to have
- Production experience in both native iOS and native Android
- Experience with Kotlin Multiplatform, Compose Multiplatform, or another cross-platform mobile technology
- Experience building AI-enabled product capabilities using model APIs, retrieval, evaluation datasets, guardrails, observability, or human-in-the-loop workflows
- Experience with mobile security, accessibility, performance optimisation, SDK development, or enterprise application distribution
- Experience in banking, fintech, or another regulated environment
- Experience with cloud services, backend APIs, web applications, or data pipelines supporting mobile products
Full description
The Job in Short
At Backbase, we build secure, enterprise-grade digital banking software used every day by millions of people worldwide. As a Senior AI Applied Engineer with mobile depth, you will help design, build, and evolve the Backbase Mobile Platform and the product capabilities around it.
You bring deep expertise in iOS, Android, or both. That expertise is the strong vertical of your T-shaped profile - not a boundary around the work you can do. Using AI-assisted and agentic ways of working, you will contribute across mobile platforms and the wider product stack, including UI, delivery pipelines, testing, and documentation.
This role combines mobile craftsmanship with broad product ownership. We are looking for an engineer who can make sound platform-specific decisions, use agents to move effectively through unfamiliar technology, and remain accountable for the quality, security, and business outcome of everything they ship.
Meet the Job
You will join a multidisciplinary squad responsible for delivering end-to-end digital banking capabilities, from initial discovery and technical design to release, adoption, and production support. You will solve complex product and engineering problems that cross platform and system boundaries.
As a senior engineer, you will be a technical authority within your area of depth and a force multiplier for the wider team. You will shape architecture, review critical changes, mentor peers, lead complex investigations, and create reusable patterns and automation that improve how teams work.
AI agents are a normal part of your engineering workflow. You will use them to investigate codebases, compare implementation options, create prototypes, generate and maintain tests, diagnose failures, automate repetitive work, and deliver changes beyond your strongest platform. You will define clear constraints and success criteria, evaluate the evidence, and never treat generated output as inherently correct.
What you'll do
- Design, build, test, and maintain complex mobile applications, frameworks, libraries, and SDK capabilities for iOS, Android, or both.
- Lead product features across the full software development lifecycle, from ambiguous requirements and architectural design through implementation, release, observability, and continuous improvement.
- Use AI coding agents and automated workflows to accelerate delivery across iOS, Android, APIs, services, and CI/CD without lowering engineering standards.
- Decompose complex work into bounded, verifiable tasks; equip agents with the right context and constraints; and critically review, test, and refine their output.
- Contribute safely outside your primary area of depth by learning unfamiliar systems quickly, following local conventions, and seeking appropriate domain review.
