We are not looking to just be part of the industry, but to revolutionize it.\nAI-Driven Engineering Culture\nWe are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software - not an experiment, not a trend, and not an optional add-on.\nAI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential-AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.\nThe Role\nYou'll be building and maintaining mission-critical payment systems that handle massive scale and directly impact millions of users worldwide.\nWhat you will be doing\nWrite well-designed, testable and scalable code in a timely manner\nTake part in the full development cycle from sprint planning to release cycles\nEnsure smooth development and cooperation between dev teams and product owners\nBuild and maintain high-load systems that handle massive scale\nTroubleshoot production issues using metrics, alerts, monitoring and profiling\nContribute to seamless scaling and automation initiatives\nWhat we are looking for\nStrong Java Core expertise (Java 8+) with proven track record in enterprise environments\nDeep expertise in multithreading and high-load systems architecture\nSolid SQL knowledge and database optimization skills\nStrong experience with Docker and containerization ecosystem\nExcellent troubleshooting skills with production monitoring tools\nStrong English communication skills in speaking and writing\nBonus points for: Experience with Clickhouse, GCP, Kafka ecosystem, ElasticSearch, Ebean, Protobuf, InfluxDB/Grafana, Google Services integration, SPA and modern mobile/web technologies, or fintech experience.\nMain technologies: Java, Spring, Spring Boot, Ebean-ORM, Quartz, Maven, Resteasy, Flyway, PostgreSQL 15, HTTP/Websockets, Netty, K8S/Docker, GCP, Jenkins, ELK, Grafana\nWhy you will love it\nYou’ll be at the forefront of AI-driven engineering in a fast-scaling environment where your code directly impacts millions of users. Work with cutting-edge technology (latest Java, Spring Boot, GCP, Kubernetes) while enjoying full remote flexibility, generous leave, and real opportunities for growth. Join a team that treats AI as a core engineering tool-not an experiment-and where engineering excellence, speed, and meaningful impact are part of everyday work.","description_format":"text","description_chars":3014,"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":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-05T01:09:39Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.412,"p_room":0.28,"age_days":161,"expected_fill_days":24,"reasons":["conf:1","velocity","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/b2spin-senior-java-enginner-payment-team","json_url":"https://alion.io/job/b2spin-senior-java-enginner-payment-team.json","meta":{"generated_at":"2026-10-23T09:58:32Z","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":15202,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":97262},"rest":"https://alion.io/mcp/rest/get_company?id=97262"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fb2spin-senior-java-enginner-payment-team"},{"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%2Fb2spin-senior-java-enginner-payment-team"},{"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%2Fb2spin-senior-java-enginner-payment-team"},{"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/b2spin-senior-java-enginner-payment-team\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fb2spin-senior-java-enginner-payment-team"}]}
