WHY SAFETY?

At Roblox, we strive to connect a billion people with optimism and civility, and the Safety organization’s mission is to become the leader in civil immersive online communities. We systematically detect, remove, and prevent problematic content and behavior, and we make Roblox accounts secure and free from compromise. We cover a broad area of the tech spectrum, including machine learning, classifiers for 3D models, experimentation, automation, detection workflows, and AI-powered text filters. Aligned and partnering with product teams, we use this toolbelt to discover new opportunities, influence and shape the product roadmap and prioritization, build safety products, and measure the impact on our community of users and developers. In doing so, we keep Roblox safe, civil, and inclusive, and we foster positive relationships between people around the world.

WHY Safety Experience?
Safety is paramount at Roblox, and it shows up in everyday human moments. A rating left on a game. The words a Customer Care agent chooses when replying to a report. Whether a suspended account feels like a fair call or an arbitrary one. How fast someone gets back into an account they thought was gone for good, guided by an agentic Customer Care experience. Every one of these moments runs through systems we build: our tools, our data pipelines, our audit trails.

We are looking for a Principal Software Engineer to join our Safety Experience team within the Trust & Safety organization. In this role, you will revolutionize Roblox users' perception of safety by developing agentic applications and complex technical solutions at scale.

You Will:

• Design and build agentic workflows and technical solutions for both customer facing applications and internal use cases.
• Stay familiar with recent trends in LLMs and develop innovative solutions and features for the chatbot, while optimizing for  cost.
• Influence the team's roadmap and long-term strategy in collaboration with product, operations, and other cross functional stakeholders to develop the next generation of safety experience. 
• Provide technical leadership,  influencing decisions within and beyond the pod
• Mentor junior engineers to strengthen their technical skills and support their professional growth.

You Have:

• A Bachelor's degree in Computer Science, or a related field, with a minimum of 8 years of hands-on experience. A graduate degree is highly preferred.
• Proven experience developing innovative solutions using LLMs is required.
• Extensive experience with modern programming languages such as C#, Java, Python, or similar, with a strong emphasis on writing efficient, maintainable, and scalable code.
• In-depth knowledge of contemporary software design patterns, including microservice architecture, RESTful APIs, and Remote Procedure Calls (RPC), with a proven track record of building robust and scalable systems.
• Demonstrated ability to develop end-to-end solutions for complex technical challenges, collaborating across multiple teams from conception through to launch.
• Proven experience developing innovative solutions using LLMs is highly desirable.
• Prior experience in machine learning is helpful.

You Are:

• A Technical Leader: You have initiated and facilitated challenging technical solutions. Your technical expertise influences product direction. You foster a culture of technical excellence.
• Versatile: You're a jack of all trades and you are comfortable with several languages and technologies already; you are adaptable in any situation. You are resourceful, and take a creative and strategic approach to solving hard problems.
• Analytical: Excited to investigate large, ambiguous problems, and quantify the problems and the solutions.
• User Oriented: You always start with the needs of the user, whether they are Roblox users or internal engineers before architecting a solution.
• Team Oriented: You lift up your peers and find ways to make the team stronger.
