Job Title

Senior Software Engineer (Client) - Demonware - Vancouver, BC

Requisition ID

R027559

Job Description

Your Mission

The Client Code team builds and maintains the client-side online services SDK used by Call of Duty and other Activision titles. We own the C++ libraries and tooling that provide core network communication for games as well as connect game clients to Demonware’s wide range of online services.

As a Senior Software Engineer (Client Code), you will design, implement, and evolve C++ client libraries and tools that power some of the biggest game launches in the world. Partnering closely with game studios and Demonware service teams, you will deliver robust APIs, efficient networking solutions, and reliable build pipelines across console and PC platforms. In this role, you will have the opportunity to raise the bar for build systems, CI processes, and overall developer experience, while owning and evolving core C++ client SDK components used across multiple AAA titles. You will also contribute to improving the reliability and observability of client-to-backend communications at massive scale and play a key role in mentoring engineers in modern C++, networking fundamentals, and build and tooling best practices.

This role is based in our Vancouver, BC office and follows an onsite work schedule of four days per week. Work arrangements may change at the company's discretion to meet business needs.

What You Bring To The Table

Priorities can often change in a fast-paced environment like ours, so this role includes, but is not limited to, the following responsibilities:

Own our build pipelines for the Client Code SDK:
- Maintain and improve Windows and console builds to accelerate developer feedback loops.
- Keep CI fast, reliable, observable, and well-instrumented for all our C++ products.
Design and implement new features in our C++ client libraries.
Debug complex production issues that span client, network, and backend services, using logs, packet captures, and focused reproduction harnesses.
Collaborate with game teams to integrate SDK features, review usage patterns, and promote best practices.
Write and review technical designs, perform code reviews, and help define coding standards for the team.
Contribute to internal tooling (build systems, test harnesses, diagnostics tools) that make online features easier to test, validate, and ship.

Minimum Requirements

8+ years of professional software engineering experience with C++ within games, engines, SDKs, or other performance-sensitive systems.
Strong expertise in modern C++
Experience with C++ build systems e.g. CMake
Experience with building effective backwards compatible APIs or libraries.
Strong understanding of networking fundamentals such as TCP/UDP, HTTP/HTTPS, and REST APIs.
Proficient with network debugging and observability tools such as Wireshark
Familiarity with CI/CD pipelines, e.g. Jenkins or TeamCity.
Proven ability to analyze and resolve complex cross-functional problems spanning client applications, backend systems, and infrastructure.
Strong communication and collaboration skills with experience working directly with stakeholders, customers, and distributed engineering teams.
Comfortable operating in live-service or service-oriented environments with shared ownership, operational responsibilities, and on-call/support rotations where appropriate.

Extra Points

Experience integrating online services SDKs into games or other client applications.
Familiarity with console development environments (PlayStation, Xbox, Nintendo, etc.).
Experience building headless clients, bots, or load-test clients for multiplayer or online features.
Prior work with:
- Game or engine-level networking layers.
- Telemetry / logging / metrics systems for a game or local client application.
- Crash reporting, exception handling, or stability tooling.
Contributions to developer experience: internal tools, documentation, sample projects, or code-generation pipelines.
Interest in game development and online play – e.g., understanding of matchmaking, parties, lobbies, progression systems, or anti-cheat integration.

Your Platform

Demonware is a member of the Activision family of studios. We work alongside engineers and creatives at our AAA partner studios and deliver the online and data services required by our massive franchises.
