Own the full engineering lifecycle of mobile growth initiatives - from shaping the brief with product and business through to production launch and iteration.
Build and optimise growth systems - including funnel instrumentation, referral mechanics, acquisition loops, and experiment frameworks — directly serving the mobile user base.
Collaborate closely with Product Manager, Business Development, and local market teams across multiple regions to translate commercial goals into concrete, data-backed engineering proposals.
Apply AI coding tools actively in your workflow to accelerate development, improve code quality, and bridge across tech stacks where needed.
Drive technical decision-making on growth infrastructure, articulating trade-offs clearly and defending or revising your positions based on evidence.
Mentor engineers on the team and help establish a culture where engineers bring solutions, not just responses.

8+ years of software engineering experience with a track record of shipping production-quality systems at scale.
Hands-on growth engineering experience — funnel optimisation, experiment frameworks, acquisition or referral systems — in a consumer-facing (ToC) product context.
Understanding of mobile users: how they behave, what drives retention and conversion, and how mobile-native growth mechanics differ from web.
Actively uses AI tools as a core part of your engineering workflow — not just for code generation, but for building repeatable workflows and bridging across stacks.
Outspoken and proposal-driven: you come to the table with a point of view, push back when you disagree, and bring data and a counter-proposal rather than just flagging concerns.
Strong cross-functional communication — comfortable working with Product Manager, Business Development, and local markets to align on goals and hold the line on engineering quality.
Data instincts: you think in funnels, know how to instrument what matters, and use metrics to drive decisions.

Mobile development experience in iOS (Swift/Objective-C) or Android (Kotlin/Java) — or backend experience building growth systems that serve mobile apps directly (e.g. growth APIs, attribution pipelines, notification infrastructure).
Experience with Rust or other systems languages — especially candidates who have recently migrated from mobile-native stacks and are building fluency in backend tooling.
Depth in mobile attribution and MMPs (AppsFlyer, Adjust, SKAdNetwork).
ASO operational experience (App Store Connect, Google Play Console).
Experience building referral systems, k-factor mechanics, or anti-fraud layers.
Background in fintech, crypto, or regulated consumer financial products.
Experience operating across US, EEA, and APAC markets.
A/B experiment framework ownership at meaningful scale.
