Are you an experienced mobile engineer with a track record of leading large-scale technical initiatives and shaping mobile architecture across complex products?

As a Principal Mobile Engineer, you’ll take ownership of mobile engineering direction across critical player-facing systems. From initial player onboarding through to ongoing engagement, you’ll define and deliver scalable, secure mobile solutions that support key journeys across the RuneScape franchise.

Own and drive mobile engineering initiatives across multiple projects, ensuring alignment with product goals and long-term technical strategy.
Define and evolve mobile architecture across iOS and Android, ensuring scalability, performance, and maintainability.
Lead the delivery of complex technical solutions, coordinating across teams and managing dependencies at a system level.
Establish and uphold engineering standards across mobile development, including code quality, testing, and deployment practices.
Identify and drive improvements to systems, services, and engineering processes to support reliable, scalable delivery.
Work closely with backend, product, and platform teams to ensure seamless integration across services and user journeys.
Guide technical decision-making, balancing short-term delivery with long-term system health and evolution.

What we’re looking for:

Proven track record leading large-scale mobile engineering initiatives within production environments.
Deep expertise in native mobile development across iOS (Swift / Objective-C) and Android (Kotlin / Java).
Strong experience defining and evolving mobile architecture integrated with backend microservices.
Strong understanding of the software development lifecycle, including CI/CD, testing, and release practices.
Experience operating across teams to manage technical direction, dependencies, and delivery outcomes.
Advanced debugging, performance optimisation, and system-level problem-solving capability.
Experience with C++ is an advantage.

What we offer:

When you join Jagex you can look forward to a generous Perks & Benefits package including:

Private Healthcare, including Dental Plan.
Discretionary annual performance bonus.
Minimum 6% Pension contributions.
Life Insurance.
Enhanced family leave policies from day 1.
