Software Engineer - SRE & Resiliency Infrastructure

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect across 3D immersive digital experiences. As Roblox scales toward its ambitious goal of 1 billion daily active users (DAUs), maintaining platform stability, performance, and resilience is paramount.

As a Software Engineer on the Reliability team, you will drive the evolution of Roblox’s core production infrastructure, ensuring that global systems meet the highest standards of fault tolerance and availability. In this hands-on engineering role, you will write resilient software libraries (circuit breakers, retries, adaptive concurrency limits), standardize "golden path" developer tooling, build automated release testing capabilities, and deploy production guardrails like generalized canarying and automated capacity load-testing services.

Key Responsibilities

• Resiliency & Fault-Tolerance Libraries: Architect and maintain core software libraries (retries, circuit breakers, rate limiters, adaptive concurrency controls) that promote system resilience across the platform.
• Golden Path Automation: Build, automate, and standardize platform processes to create a unified "golden path" for service delivery across the developer ecosystem.
• Production Guardrails & Load Testing: Engineer tools that validate release candidate capacity using automated load-testing suites before code reaches production environments.
• Observability & Capacity Monitoring: Develop performance monitoring microservices and telemetry frameworks to detect platform degradation and capacity bottlenecks early.
• Canary & Deployment Verification: Create monitoring and verification services that audit production deployments using generalized canary testing and automated alert routing.
• Agile Execution & Project Planning: Participate in sprint cycles, break down complex infrastructure initiatives into clear project milestones, and track delivery progress.

Requirements

Practical Experience & Core Technologies

• 4+ years of professional experience in software engineering, site reliability engineering (SRE), or production platform infrastructure.
• Strong proficiency in modern compiled or object-oriented programming languages (Go, C#, Java, or similar).
• Demonstrated habit of building clean, well-tested, deeply reliable tools and driving their adoption across engineering teams.
• Hands-on experience with agile project lifecycles, sprint planning, task breakdown, and technical documentation.

Education & Work Logistics

• Bachelor’s degree (or equivalent professional experience) in Computer Science, Software Engineering, or a related field.
• Ability to work onsite 3 days per week (Tuesdays, Wednesdays, Thursdays) at Roblox HQ in San Mateo, CA.
• Note: Roblox may not be able to support certain visa categories or future H-1B sponsorship for this position.

Preferred Qualifications

• Prior experience working within dedicated Site Reliability Engineering (SRE) or core infrastructure organizations.
• Practical experience designing distributed systems, high-concurrency microservices, or cloud-native observability tooling.
• Deep familiarity with chaos engineering principles, disaster recovery testing, or automated canary deployment strategies.

Total Rewards & Workplace Benefits

• Compensation: Base salary of $243,290 – $295,250 USD + comprehensive long-term equity grant package.
• Healthcare & Wellness: Comprehensive medical, dental, and vision coverage options; mental health resources and wellness stipends.
• Financial Security: 401(k) program with company matching; life and disability insurance.
• Time Off & Work Culture: Generous PTO policies, observed holidays, and hybrid workplace flexibility.
