Our DoubleCheck platform combines advanced authentication, proprietary technology, AI, and novel UX to collect and confirm payment details. DoubleCheck has defined a new category: verifying the safe transfer of financial information and assets.\nWalrus is led by PhD computer scientists and security researchers, with decades of experience in engineering, cybersecurity, and cryptography, and many research accomplishments at Harvard, Stanford, MIT, the University of Chicago, Columbia, UTexas, and NYU.\nWe’re backed by one of the world's leading fintech VC funds, as well as founders and former executives of Twitter, Google Maps, Databricks, and Kayak.\nThe role\nYou will be part of the core team at Walrus, working on our flagship product. You will design, build, and own exciting new modules; examples include payments, reputation, and new kinds of authentication.\nWe are an early-stage company, so you and the team will work together to create standards and culture that will endure for years to come. Of course you’ll get to design and innovate solutions to hard problems, and write a lot of code. But beyond that, as all entrepreneurial software teams do, you’ll be able to design ways of approaching software development.\nWe are looking for people who are thoughtful, not only about software problems, but about how teams work together to solve them, and how people collaborate to build an energizing and supportive workplace.\nAbout you\nYou are someone who cares a lot about designing software in a thoughtful way that takes into account bug prevention, testability, and maintainability. You are comfortable with the idea that product design should be data-driven, using evidence rather than opinion.\nYou are:\nExperienced with tools for testing. You know that the best software developers demonstrate that their code works, rather than dumping it on a QA department.\n\nCurious, and have an interest in teaching and learning from your colleagues.\n\nA strong written communicator.\n\nGraduating in December 2027, anytime 2028, or spring 2029 with an undergraduate degree in computer science, math, physics, or electrical engineering.\n\nOptionally\nWe strongly encourage you to apply even if you don't meet all the criteria listed; the description is meant to be indicative, not a precise description of a pigeonhole.\nYou have internship or co-op experience designing, building, and deploying sophisticated web applications.\n\nYou have experience with modern UI frameworks, web standards, and web development best practices.\n\nYou have a detailed understanding of the design of data models for use in relational databases.\n\nYou have used cloud infrastructure to deploy reliable and scalable web applications.\n\nYou have built authentication flows and/or implemented secure APIs.\n\nYou have built or used tools for data analysis, performance profiling, and debugging.\n\nWhat it’s like to work with us\nWe’re a tight-knit, early-stage team that’s focused on building a product that our customers love. We have a strong company culture based on collaboration, ownership, and mentoring. We meet sparingly and efficiently. We understand our innate biases and celebrate diversity. We have a low-ego workplace, where we provide the tools for everyone to do their best work. You will work closely with the leadership team, and have room for extensive growth within the company.\nRemote work is welcomed, but candidates who wish can report to work in NYC.\n\nFor full time permanent employees, Walrus offers competitive compensation and benefits, including salary, equity, paid medical insurance, dental, vision, company contribution to wellness, good coverage for dependents, parental leave, retirement, relocation assistance, and unlimited PTO.\n\nWe believe talent comes from all backgrounds and walks of life, and are committed to providing a comfortable environment for everyone to work.\nThis is a temporary internship position with full time hours. The annual base pay for this internship is $75,000 - $110,000 (depending on location and experience). This information is provided per the New York City Human Rights Law.\nApplicants must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment visa at this time.","description_format":"text","description_chars":4594,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Health insurance","Parental leave","Relocation assistance","Unlimited PTO"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Crypto Payments","Information Security"],"lifecycle":[{"event":"open","at":"2026-10-21T22:43:32Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":4,"expected_fill_days":27,"reasons":["conf:1","win:early","comp:junior"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/walrus-security-inc-full-stack-developer-intern","json_url":"https://alion.io/job/walrus-security-inc-full-stack-developer-intern.json","meta":{"generated_at":"2026-10-26T13:19:24Z","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":18519,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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":689619},"rest":"https://alion.io/mcp/rest/get_company?id=689619"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwalrus-security-inc-full-stack-developer-intern"},{"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%2Fwalrus-security-inc-full-stack-developer-intern"},{"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%2Fwalrus-security-inc-full-stack-developer-intern"},{"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/walrus-security-inc-full-stack-developer-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwalrus-security-inc-full-stack-developer-intern"}]}
