Their technology powers billions in transaction volume across 180+ countries, and they're scaling aggressively across multiple engineering teams. This is a backend-heavy role for engineers who want to build systems that genuinely move money at scale.\nWhat you'll be doing\nYou'll own and extend microservices responsible for secure, reliable value transfer across blockchain and traditional banking protocols. You'll design APIs used by developers worldwide, integrate with major banks and financial platforms, and collaborate closely with product and engineering on architecture and system design. Multiple teams are hiring - liquidity, payments, developer tooling, stablecoin operations, and more.\nWhat they're looking for\n6+ years of professional software development in object-oriented languages; deep Java expertise is the primary requirement. Go is used but secondary. C#/.NET-centric backgrounds are not a fit.\nExperience leading small technical teams (2-4 engineers) on architecture and design decisions\nSolid background in payment systems - credit cards, bank transfers, payment rails\nStrong RESTful API design and development fundamentals\nExperience with cloud platforms (AWS, GCP, or Azure) and SQL schema design\nCS degree or equivalent\nWeb3/blockchain exposure is a plus, not a requirement\nMust be US-based with meaningful Pacific Time availability - this team operates on PT and overlap is a real requirement, not a preference\nCompensation $150.000 - $200,000 base + equity. Comp is flexible for the right person.\nCompensation\nThe base pay range for this role is $150,000 - $200,000 per year.","description_format":"text","description_chars":1897,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto"],"lifecycle":[{"event":"open","at":"2026-10-13T03:57:46Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.112,"p_room":0.28,"age_days":139,"expected_fill_days":7,"reasons":["conf:1","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/syndesus-senior-software-engineer","json_url":"https://alion.io/job/syndesus-senior-software-engineer.json","meta":{"generated_at":"2026-10-13T19:53:29Z","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":30449,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":4420272},"rest":"https://alion.io/mcp/rest/get_company?id=4420272"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsyndesus-senior-software-engineer"},{"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%2Fsyndesus-senior-software-engineer"},{"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%2Fsyndesus-senior-software-engineer"},{"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/syndesus-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsyndesus-senior-software-engineer"}]}
