We Need You

The minions of Hell are growing stronger...

Join us as we write the next chapter in the Diablo universe! Diablo Immortal, a Massively Multiplayer Action-RPG mobile game set in the world of Sanctuary, lets heroes slay demons anywhere, at any time. Come work with us, and together, we'll create something amazing. Our team of passionate developers is growing.

We are seeking a Senior Software Engineer to operate at the intersection of platform engineering, live operations, and large-scale game delivery, building systems that directly impact player experience, performance, and cost at global scale.

In this role, you will operate as a domain expert across tooling, live operations, and platform integrations, acting as a technical owner for complex systems and driving solutions that impact multiple teams. You will partner closely with internal Blizzard teams and external partners to ensure scalable, reliable integration between first- and third-party technologies, while improving how teams develop, ship, and operate the game.

This role offers a hybrid work week, with a mix of remote and on‑site days, based out of our Irvine, CA studio. While hybrid is the standard arrangement, candidates may also choose to work on‑site full‑time if preferred.

Responsibilities

* Develop and improve build, release, and deployment pipelines (e.g., Jenkins, CI/CD), driving automation and reliability within your domain.

* Support and enhance platform integration and distribution across mobile (Google Play / Apple) and PC (), ensuring smooth releases at scale.

* Optimize download, patching, and build size efficiency (e.g., patching strategies, in-game delivery improvements).

* Design and build live service tools and dashboards to support monitoring, incident response, and operational visibility.

* Analyze and improve backend performance and infrastructure efficiency (e.g., scaling strategies, cost optimization), partnering with relevant teams.

* Drive technical direction and execution of technical roadmaps, translating product and engineering goals into actionable plans within your area.

* Partner with producers and cross-functional teams to improve workflows, delivery pipelines, and release processes.

* Collaborate with internal and external partners to design and implement scalable technical solutions.

* Ensure systems meet platform and regulatory requirements (e.g., privacy, compliance), surfacing risks and proposing solutions.

Minimum Requirements

* 8+ years of experience in game development, platform engineering, or live services, with a track record of owning and delivering large-scale systems in production.

* Proven ability to define technical direction and drive execution across multiple teams, including internal and external partners.

* Strong proficiency in one or more languages such as JavaScript, Python, or C#.

* Experience with distributed systems, platform integrations, or large-scale backend architecture.

* Experience with CI/CD systems (e.g., Jenkins) and release automation.

* Experience working with cloud infrastructure (AWS or GCP).

* Ability to independently drive large, ambiguous technical problems to completion.

* Demonstrated ability to balance tradeoffs across performance, scalability, cost, and development velocity.

* Strong collaboration and communication skills across engineering and non-engineering partners.

* Experience working in ambiguous environments, driving clarity, prioritization, and execution

Bonus Points

* Experience with cross-platform ecosystems (mobile + PC).

* Familiarity with  or similar platform technologies.

* Experience optimizing game distribution, patching, or backend cost efficiency.

* Background working on MMOs or large-scale live service games.
