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. \nA 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.\nWhat You’ll Do:\nJoin the Roblox Ledger team and build the system of record for a global economy. Our north star is that all movement of value on Roblox is tracked on the Ledger, and that every unit of value - virtual currency, fiat, or digital asset - is accurately tracked, perfectly balanced, and fully auditable. That makes the Ledger the trusted foundation for our users, creators, and economy.\nWe are the source of truth for the economy in both directions: every write of value, and every read of it. The same authoritative record that settles a transaction also has to answer the questions people ask about it - balances, history, statements, reconciliation, and analytics - so that read paths do not drift from the book of record. Robux already runs entirely on our zero-balanced, double-entry ledger, and Creator Wallets launch in December 2026. As a Senior Software Engineer, you will design, build, and scale the systems that make this true, in a domain where correctness is the product rather than a feature.\nYou Have: \n4+ years of backend software engineering experience, demonstrating proficiency in designing, building, and maintaining robust and scalable systems (e.g., microservices, APIs).\nStrong problem-solving skills and experience debugging complex issues in distributed systems.\nExperience in managing projects, planning and executing work across different workstreams.\nStrong collaboration skills, ability to work across teams and organizations, mentoring and guiding junior engineers.\nBachelor's degree in Computer Science, Computer Engineering, or a similar technical field.\nExperience in financial infrastructure, ledgers, accounting, or another domain where accuracy is non-negotiable is highly desirable. Experience building a ledger or double-entry system at another company is a strong plus.\nExperience with large-scale data or analytical systems (OLAP, event-driven pipelines, or similar) is a plus but not a requirement.\nYou will:\nWork closely with Finance, product, and other economy engineering teams to make every movement of value correct at the source.\nArchitect, design, implement, and operate the ledger services that record every movement of value on Roblox.\nProactively identify and address correctness, performance, auditability, and operational risks in systems where a single bad entry is a financial incident.\nDesign idempotent, exactly-once write paths, plus the reconciliation that proves the books balance and the precision guarantees other teams build on.\nOwn both sides of the ledger: the write path that records value, and the read path that serves balances, history, and analytics from the same source of truth.\nUphold high standards for code quality, test coverage, and maintainability, fostering the culture of engineering excellence.\nFor roles that are based at our headquarters in San Mateo, CA: The starting base pay for this position is as shown below. The actual base pay is dependent upon a variety of job-related factors such as professional background, training, work experience, location, business needs and market demand. Therefore, in some circumstances, the actual salary could fall outside of this expected range. This pay range is subject to change and may be modified in the future. All full-time employees are also eligible for equity compensation and for benefits as described on this page.\nAnnual Salary Range\n$196,750—$243,290 USD\nRoles that are based in an office are onsite Tuesday, Wednesday, and Thursday, with optional presence on Monday and Friday (unless otherwise noted).\nRoblox provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws. Roblox also provides reasonable accommodations to candidates with qualifying disabilities or religious beliefs during the recruiting process.\nFor US based roles only, please note the Company may not be able to employ candidates for this role who have United States work authorization related to certain U.S. visa categories, or support future H-1B sponsorship at this time.","description_format":"text","description_chars":5102,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Crypto Wallets","Mobile Games","Game Development","Metaverse"],"lifecycle":[{"event":"open","at":"2026-11-05T03:11:43Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 247 · green card filings: 82","filings_12m":247,"filings_prev_12m":236,"green_card_filings_12m":82,"median_offered_wage_usd":245038,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":161}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":1,"expected_fill_days":64,"reasons":["conf:1","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":243290,"is_top_pay":true},"html_url":"https://alion.io/job/roblox-corporation-senior-software-engineer-ledger","json_url":"https://alion.io/job/roblox-corporation-senior-software-engineer-ledger.json","meta":{"generated_at":"2026-11-06T09:27:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17094,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":246},"rest":"https://alion.io/mcp/rest/get_company?id=246"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Froblox-corporation-senior-software-engineer-ledger"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Froblox-corporation-senior-software-engineer-ledger"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Froblox-corporation-senior-software-engineer-ledger"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/roblox-corporation-senior-software-engineer-ledger\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Froblox-corporation-senior-software-engineer-ledger"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3785065}},{"tool":"search_jobs","arguments":{"company":"roblox.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3785065},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
