Your mission will be:

Flutter Platform Strategy:

• Own the technical vision and roadmap for Luno's Flutter platform. Define the migration strategy across fleets, establish architectural standards, select and govern shared tooling, and make the high-impact decisions that will shape the codebase for years. Present this strategy to engineering leadership and the wider organisation.

Architecture & Technical Standards:

• Design and document Luno's Flutter architecture, including state management, layering patterns, platform channel strategy, design system integration, accessibility standards, and localisation architecture. Ensure consistent application across all product fleets through clear reference implementations, RFCs, and design review.

Migration Programme Delivery:

• Partner with fleet engineers, engineering managers, and the ADL team to sequence and de-risk the full migration programme. Identify critical path dependencies, provide technical governance on high-risk migration workstreams, and ensure quality gates are maintained as velocity increases.

Engineering Community & Craft:

• Lead the Flutter chapter at Luno. Run design reviews, write decision records, maintain the internal Flutter handbook, and create the learning environment where mid and senior Flutter engineers grow fast. Represent Luno externally: conference talks, open-source contributions, and developer community engagement.

Commercial & Product Influence:

• Translate complex technical constraints into clear product implications. Partner with product and design leaders to ensure the Flutter platform unlocks Luno's product ambitions, rather than limiting them. Influence the roadmap with architectural insight, and proactively surface opportunities that new Flutter capabilities create.

A little about you: Minimum Role Requirements

• Degree in Computer Science, Software Engineering, or a related field - or equivalent professional experience.
• 7+ years of professional mobile engineering experience, with at least 3 years leading hybrid development on production applications at significant scale.
• Expert-level Dart and Flutter knowledge: rendering pipeline, widget internals, platform channels, custom render objects, Impeller, and the Flutter engine.
• Proven experience designing and governing cross-team Flutter architectures and migrating large, complex legacy mobile applications.
• Deep expertise in testability - widget, integration, golden-image, and end-to-end test strategies at programme scale.
• Strong understanding of mobile release engineering: automated pipelines, phased rollouts, feature flags, crash monitoring, and A/B testing in a Flutter context.
• Track record of defining and driving adoption of engineering standards across multiple teams.
• Prior staff/principal engineering or equivalent IC leadership experience strongly preferred.
• Advantageous: native iOS (Swift) or Android (Kotlin) background; prior fintech or regulated-app experience; contributions to open-source Flutter packages.
