Job description

Overview

Our engine, Titan, powers some of the highest‑grossing games in mobile – titles that have generated billions in revenue and reach hundreds of millions of players. We are investing heavily into the future of Titan, and as part of that investment we’re building a brand‑new Reliability team: an autonomous, high‑skill group that will work alongside our engine teams, empowering them to work safer, faster, and easier through better infrastructure, automation, and feedback loops. The role that Reliability plays is crucial to the success of Titan’s future. As agentic workflows become more common the pace of iteration rises, and confidence in what we ship becomes the bottleneck. We see this team as a strategic bet in solving that problem — building the validation surfaces, automation, and reliability loops that help our engine teams move faster without increasing risk to what matters most – our games and players.

Team Philosophy

This is an AI‑forward engineering team by design. We are not treating AI as a side tool; we are building around the reality that modern engineering will increasingly depend on AI‑assisted workflows for validation, automation, and test generation — with strong engineering judgment and clear guardrails.

Role Focus

This role is client‑leaning, focused on the engine and runtime: C++, mobile platforms, runtime behaviour, performance, and the practical challenges of validating shared engine changes before they reach games.

Qualifications

• Strong professional experience in modern C++
• Engine/runtime development experience
• Experience with build systems, automation, and developer tooling
• Interest in AI-assisted workflows
