Our solutions power payment experiences across Android-based payment terminals, mobile devices, and integrated merchant environments.\nWith teams across several countries, we work collaboratively to build reliable payment technology that operates in highly regulated and security-critical environments.\nThe Role\nWallee is looking for an experienced Android Engineer to join our payment terminal engineering team in Vilnius.\nYou will work primarily on our Android-based payment terminal platform, developing and maintaining software that sits at the heart of payment processing on physical terminals.\nThis is not a typical consumer Android application role. You will work close to the Android platform, payment applications, terminal hardware, network communication, payment protocols, and security-sensitive transaction flows.\nYou will collaborate with engineers across Android, TypeScript, backend, payment protocols, QA, and certification to deliver reliable software used on payment terminals in production.\nTasks\nThe Impact You’ll Make\nBuild Payment Terminal Software: Develop and maintain Android applications and components running on dedicated payment terminals.\nWork Across the Platform: Integrate Android components with payment applications, device services, hardware interfaces, APIs, and communication protocols.\nDevelop Reliable Transaction Flows: Implement and troubleshoot payment functionality where correctness, stability, and predictable behaviour are critical.\nChampion Security: Work with security-sensitive systems involving TLS, certificates, cryptographic operations, secure key handling, and PCI requirements.\nSolve Complex Problems: Investigate issues across application, Android platform, device, network, and payment protocol layers.\nDrive Engineering Quality: Review code, improve architecture, write automated tests, and help maintain a reliable and maintainable codebase.\nCollaborate Across Teams: Work closely with Product, QA, certification teams, and other engineers to turn payment requirements into production-ready solutions.\nProvide Technical Expertise: Support complex technical investigations and help other teams understand terminal behaviour, APIs, and integration requirements.\nRequirements\nWhat You Bring to the Table\nStrong Android Experience: Solid professional experience developing Android software using Kotlin and Java.\nAndroid Platform Knowledge: Good understanding of Android application architecture, services, lifecycle, IPC, threading, networking, and debugging.\nEngineering Fundamentals: Ability to design maintainable software, understand existing complex systems, and confidently troubleshoot production issues.\nNetwork Knowledge: Practical experience with TCP/IP, HTTP, and TLS.\nSecurity Mindset: Understanding of security fundamentals such as encryption, certificates, symmetric/asymmetric cryptography, hashing, and secure data handling.\nQuality First: You write readable, maintainable, documented, and well-tested code rather than simply making things work.\nTypeScript: Experience with TypeScript is a strong advantage, as parts of our payment terminal stack use it.\nCommunication: Professional fluency in English and the ability to collaborate effectively in an international engineering environment.\nExperience with payment terminals, payment systems, embedded Android devices, POS systems, EMV, PCI, or payment protocols is an advantage, but not required.\nBenefits\nWhy Join Wallee?\nModern Workspace: A beautiful office in the heart of Vilnius - comfortable, bright, and collaboration-ready.\nTrue Flexibility: Flexible daily hours and a 4-week Work from Anywhere policy every year.\nInteresting Engineering Problems: Work on software where Android, hardware, security, networking, and financial technology meet.\nReal Ownership: Work in a flat engineering environment where you can influence technical decisions and take ownership of meaningful parts of the platform.\nGrowth & Culture: Competitive compensation of €2,500-€6,000 gross/month, depending on experience, seniority, and technical expertise, plus personal development budgets and company events.\n The Perks: Fresh fruit, snacks, and high-quality coffee.\nDon’t tick every box? Neither do most great hires. If the role sounds interesting and you have strong Android fundamentals, we’d still like to hear from you.","description_format":"text","description_chars":4482,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Company events"],"hiring_locations":[{"name":"Lithuania","iso":"LT","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Payment Processing & Gateways"],"lifecycle":[{"event":"open","at":"2026-10-20T07:58:32Z"}],"visa":[],"liveness":{"score":76,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.849,"p_room":0.9,"age_days":23,"expected_fill_days":42,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-24T06:02:35Z"},"pay":{"stated_usd_annual":80748,"is_top_pay":false},"html_url":"https://alion.io/job/wallee-android-engineer-for-payment-terminals","json_url":"https://alion.io/job/wallee-android-engineer-for-payment-terminals.json","meta":{"generated_at":"2026-10-24T23:09:08Z","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":34014,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":54332},"rest":"https://alion.io/mcp/rest/get_company?id=54332"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwallee-android-engineer-for-payment-terminals"},{"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%2Fwallee-android-engineer-for-payment-terminals"},{"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%2Fwallee-android-engineer-for-payment-terminals"},{"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/wallee-android-engineer-for-payment-terminals\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwallee-android-engineer-for-payment-terminals"}]}
