Job description

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators. 

At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there. 

A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone.

As a Software Engineer on Account Security, you will help protect Roblox users, creators, and the broader community from bad actors. We are an outcome oriented team that has the tremendous latitude to make changes across the Roblox technical stack to secure accounts. Past examples of work include work to model post-login suspicion, cryptographically bind user credentials to devices, malware detection, and work to detect and prevent asset laundering that typically is used to monetize ATOs.

You'll join Roblox's Safety organization, whose mission is to become the leader in civil immersive online communities by detecting, removing, and preventing problematic accounts, content, and behavior, and by keeping accounts secure and free from compromise. The team draws on a broad tech spectrum, including machine learning, classifiers, experimentation, automation, and AI-powered filters, partnering with product teams to shape the roadmap, build safety products, and measure impact on our community of users and developers.

You Will:

• Own the design, implementation and landing of features to prevent, detect and mitigate account takeovers.
• Collaborate cross-organizationally with partner teams in InfoSec, Economy, User, and the broader Roblox Safety org.
• Help define how goals get accomplished and have real influence over product direction.
• Instrument and analyze user interaction data (A/B tests, usage metrics) to inform design decisions and maximize product impact.
• Own implementation end to end across the stack, contributing in GoLang, Python, Typescript and Lua as projects require, using AI tools wherever possible.

You Have:

• 3+ years of experience in Software Engineering/Computer Science
• Experience working on user facing applications or services
• Proficiency in one or more programming languages such as GoLang, Python, C#, and Javascript.
• Experience collaborating cross-functionally with Product stakeholders to define requirements and deliver technical solutions.
• A strong commitment to designing, implementing, and maintaining systems that prioritize user safety, data integrity, and compliance with safety policies.

How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• Be honest about gaps; say what you did to learn and how fast you can close them.
• Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
• When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

Know your rights as a candidate and an employee:

• U.S. Equal Employment Opportunity Commission: prohibited employment practices
• U.S. Department of Labor: Wage and Hour Division

The city

The job is in San Mateo, CA. Below is what the official statistics say about living and working there.

How San Mateo compares. Among the 145 largest places in California, San Mateo is #72 by population, #132 for rent (#1 = cheapest), #28 for college degrees (#1 = most), #29 for household income (#1 = highest). Its county, San Mateo County, is #2 of 58 counties for average pay ($196,441).

The place in numbers

San Mateo has 103,105 residents (ACS 2020–2024), about 0.3% of the population of California. It covers 12 square miles of land, which works out to roughly 8,497 people per square mile. The median age is 38.3, about the same as the state median (38.3 against 37.9).

Housing

The median gross rent is $3,077 a month (rent plus utilities), 51% above the state median ($3,077 against $2,036). Over a year that is 24.1% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $1,618,700, which is 10.5 times the median household income ($153,504); a ratio above 5 usually means buying is out of reach without savings or a second income. 49.9% of households own their home, 11% below the state average (49.9% against 55.9%).

Work and pay

The San Francisco-Oakland-Fremont, CA metropolitan area has 2,373,920 jobs in the BLS wage survey, and the median pay across all occupations is $74,260 a year, 46% above the national median ($74,260 against $50,980). The biggest occupation groups are office and administrative support (226,320 jobs, median $62,120); management (223,100 jobs, median $176,340); business and financial operations (207,030 jobs, median $112,960). The area is most specialised in computer and mathematical (1.9 times) and life, physical, and social science (1.8 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($176,340) and computer and mathematical ($167,770). In 2026M09 the unemployment rate of San Mateo County was 3.9%. 68.9% of residents aged 16 and over are in the labour force. The city lies in San Mateo County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 57.7% drive alone, 4.9% use public transit, 2.7% walk, 24.8% work from home. 15.8% of workers commute 45 minutes or more, 19% below the state average (15.8% against 19.4%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

57.8% of adults aged 25 and over hold a bachelor's degree or higher, 56% above the state share (57.8% against 37.1%). 36.2% of residents were born outside the United States, 34% above the state share (36.2% against 27.0%). The poverty rate is 8.2%, 32% below the state rate (8.2% against 12.0%).

Climate

The warmest month is Sep, averaging 61°F (16.0°C), and the coolest is Jan at 51°F (10.7°C). About 515 mm (20 inches) of precipitation falls in a year; Dec is the wettest month (115 mm) and Jul the driest (2 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
