2026 Fall Co-Ops - Software Development - Demonware (Dublin)

Requisition ID:

R027550

Job Description:

This role is based onsite at the Demonware Dublin office, onsite.

About Demonware

Demonware is a member of the Activision family of studios, partnering with engineers and creatives across AAA game studios to deliver the online and data services that power some of the world’s biggest franchises — including Call of Duty and Crash Bandicoot.

We’re a technology company that values openness and collaboration. We believe the best ideas win, everyone should feel empowered to contribute, and while we take our work seriously, we don’t take ourselves too seriously.

At Demonware, you’ll find big-company challenges with a small-company culture. We support millions of concurrent users and work with technologies such as Python, C++, Java, Linux, MySQL, Erlang, and Kubernetes. Our co-op students make real contributions — many see their code running in production within days of joining.

Co-op Program Requirements

Currently enrolled in a post-secondary or graduate program

Expected graduation between January 2027 and May 2028

Available for an 8-month, in-person co-op starting September 2026

Clear written and verbal communication

Strong debugging, analytical, and problem-solving skills

Resume and transcript required

As part of the interview process, candidates will be required to complete an automated coding assessment

Specific Role Requirements

Software Engineering

Software Engineering Co-ops have touched many aspects of Demonware. Needs may shift across each team, but co-ops in the past have helped build multiplayer features, develop core backend systems, and design tools for largescale distributed services. They gain hands-on experience working with Kubernetes infrastructure, automation frameworks, and scalable data pipelines. Throughout the co-op, they collaborate in design discussions, perform root cause analysis, and automate workflows to improve reliability, performance, and developer experience.

Requirements:

Strong knowledge of Python, C++, and/or Java

Solid understanding of algorithms and data structures

Familiarity with Linux and source control (Git preferred)

Knowledge of networking fundamentals (TCP, UDP, HTTP)

Experience with SQL-based databases (MySQL preferred)

Familiarity with CI/CD concepts and tools for automating build, test, and deployment

Familiarity with Kubernetes

Exposure to security and scalability concepts

Experience building RESTful services or web applications

Clear passion for computer science showcased through personal projects, or extracurricular activities preferred

Site Reliability Engineering (SRE)

Site Reliability Engineering Co-ops maintain and evolve Demonware’s platform while contributing to the design of highly reliable operational architecture. Co-ops ensure services are scalable, maintainable, and built for players worldwide, working closely with cross disciplinary teams throughout the development lifecycle. They also collaborate with experienced engineers across global offices, gaining exposure to high impact, large scale systems engineering.

Requirements:

Strong knowledge of Python, C++, and/or Java

Solid understanding of algorithms and data structures

Experience with SQL-based databases (MySQL preferred)

Knowledge of networking fundamentals (TCP, UDP, HTTP)

Experience building RESTful services or web applications
