Senior Mobile Engineer

The Pepperstone story started in 2010. We know what it’s like to trade the world’s markets. Our team describes us as a place for the curious and the driven, and we like to do things a little differently; as a transformative global fintech we’re digital, nimble, connected, and united in our vision to create a better way to trade.

We thrive on progress – for our clients and for ourselves. Our organisational culture is ever-evolving, vibrant, diverse, global and results focused. You’ll find our 700+ team across 12 regions and 9 time zones.

Product and team context

This role sits on the Pepperstone Trading App engineering thread within Trading Experience (TREX). Related capabilities in the wider group include Mobile Platform, integrations (connectors), and the trading platform (Centrum). Department shape includes Mobile Platform plus Trading Experience teams (e.g. TREX-EVO, TREX-NOVA); exact team assignment and names are confirmed with your manager.

The Trading App is a proprietary iOS and Android client for CFD trading and portfolio monitoring—charts, watchlists, execution, margin and P&L, funding, and multi-account types (e.g. Razor / Standard). It complements MetaTrader and cTrader; it does not replace them. The app connects to Centrum and other back-office systems via connectors, and integrates services such as SCA, Auth0, Segment, notifications, and others as the stack evolves.

Delivery runs in two-week Scrum increments. A typical squad includes a tech lead or release captain, on the order of four developers and two manual QA engineers, with test automation as a parallel track. Engineering outcomes should reflect CFD realities: margin and leverage, contract-based P&L and financing, broker as counterparty, and region-specific regulation (e.g. FCA, ASIC, CySEC) affecting flows and copy.

The Role

The Senior Engineer – Mobile is an experienced individual contributor on the Trading App. They deliver complex features, raise the bar for engineering quality, and support middle mobile engineers in day-to-day execution—without substituting the separate formal mentoring programme.

They champion Continuous Delivery and work with product, analysts, and designers on data-informed delivery. They partner with the Mobile Tech Lead on technical direction and roadmap execution, and with the Engineering Manageron priorities and people processes that affect the thread.

They own substantial vertical slices from refinement through production, keep technical decisions visible in the backlog, and help keep regression risk low on iOS and Android.

Key Responsibilities

• Ship end-user-visible and technical work in two-week Scrum increments with a clear definition of done and low regression risk on iOS and Android.
• Own medium-to-large epics or vertical slices from refinement through production, including tests and observability hooks where applicable.
• Design and implement for the Trading App context: performance, offline and edge cases, secure sessions and data, and integration with back-office and real-time pricing paths.
• Participate actively in refinement so work is estimable, testable, and aligned with mobile architecture; challenge vague acceptance criteria and flag integration risks (auth, trading APIs, connectors).
• Champion code quality, modular boundaries, and release-safe changes compatible with app-store processes and internal release gates; document technical decisions and visible follow-up work in the backlog.
• Coordinate with QA (manual and automation) so scenarios, edge cases, and regression scope are agreed before the sprint ends.
• Develop, support, and maintain software using strong engineering practices—maintainable, efficient, tested, and scalable code.
• Provide input on target-state architecture; build and improve a robust Continuous Delivery practice (short-lived branches or trunk-based development, CI, automated build/test/release—e.g. GitHub Actions or team-standard tooling).
• Collaborate with platform and adjacent teams on shared tooling, frameworks, infrastructure, and contracts.
• Work with product owners, delivery leads, and business analysts; improve SDLC practices and participate in ceremonies, estimation, and refinement.
• Support middle mobile engineers through pairing, design and code review, and clear prioritisation of technical work within the sprint.
• Contribute to technical discussions, retrospectives, and engineering dojos where the team uses them.
• For release: ensure feature flags, configuration, and migration steps are documented for release captains and QA; contribute to post-release fixes and root-cause analysis for owned areas.
• Scope: Trading App mobile codebase and closely related client-side concerns—not Payments as a dedicated domain; people management and thread-wide prioritisation sit with Engineering Manager and Mobile Tech Lead.

Technology and architecture context

• Stack: React Native, TypeScript/JavaScript, and native iOS and Android (e.g. Swift, Kotlin) where the product requires it; exact boundaries follow Mobile Tech Lead guidance and the codebase.
• Delivery: CI, trunk-based development where adopted, testing discipline including TDD where the team applies it, and automation for build, test, and release.
• Design: SOLID, MVVM, Clean Architecture, and related patterns as shared standards under the Tech Lead—not a personal checklist isolated from team conventions.
  

This role reports to the Engineering Manager for the Trading App engineering thread, with day-to-day technical alignment to the Mobile Tech Lead, based in Limassol, Cyprus.
We support flexible working. This position can be performed from both a mix of at our office and from home. Your manager will share details and expectations of your team’s regular cadence of working locations.
