Around 1,500 practices across the US and Canada use us to run their front desk.\nPayments is one of our fastest-growing areas, and one of the few where the software is directly responsible for whether a practice gets paid. We're investing heavily in it over the next year: new payment methods, new products built on top of the payments platform, and a lot of work on making the core more reliable as volume grows.\nWe operate like a startup, because we are one. Scope is wide, decisions are fast, and there isn't a layer of people between you and the problem.\nAbout the role\nWe're hiring a senior backend engineer for our Payments team in Gurugram. You'll report to our Payments engineering lead and work closely with the Payments product manager.\nThis is a deep individual-contributor role. You'll write code, make architectural calls, and own systems end to end.\nWhat you'll work on\nBackend services and APIs in Python/Django. You'll own significant surfaces outright, with performance, reliability and maintainability as first-order concerns rather than afterthoughts.\nMoney movement. Card-present transactions through in-office terminals, hosted payment pages, and patient-facing payment links. Each surface has its own failure modes and its own definition of \"done correctly.\"\nRecurring billing. Scheduled charges, retries, and the logic that decides when a failed payment needs a human rather than another automated attempt.\nReconciliation. Processor webhooks arrive late, out of order, or after someone has already recorded a payment by hand. Making the ledger tell the truth anyway is a real and ongoing part of this job.\nIntegrations. Our payment processor, plus syncing payment data into third-party practice management systems - each with its own quirks and none of them forgiving.\nThe data layer. Schema design, indexing, query tuning and migrations in PostgreSQL, on a database that's growing faster than it used to.\nHow we ship. CI/CD pipelines, test automation, and releases that are safe to roll back.\nWhat we're looking for\n7-9 years building production backends, with deep Python and Django experience and genuine ownership of systems other people depended on.\nStrong PostgreSQL fundamentals - schema design, indexing, transactions, and the ability to find and fix a slow query without guessing at it.\nREST API design and third-party integration experience. You've worked against external APIs that were slow, flaky, or simply wrong, and built around that.\nRedis and Git-based CI/CD - you've built or meaningfully improved a deployment pipeline, not just used one.\nJudgement about correctness where mistakes cost money. Idempotency, retries and race conditions should be things you've had to reason about carefully, not terms you recognise.\n Clear written communication. Our team spans the US, India and Bangladesh, so a lot of thinking happens in writing.\nYou don't need every one of these to be perfect. Strong on most and curious about the rest is enough - tell us which is which.\nBonus, not required\nPayments or fintech background - Adyen, Stripe, Razorpay or similar.\nCard-present / POS terminal integration experience.\nPCI DSS exposure.\nSubscription or recurring-billing systems.\nDocker/Kubernetes, infrastructure-as-code, or observability tooling (metrics, logs, tracing).","description_format":"text","description_chars":3559,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-14T12:25:24Z"}],"visa":[],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":1,"p_active":0.503,"p_room":0.28,"age_days":208,"expected_fill_days":104,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/practice-numbers-senior-software-engineer","json_url":"https://alion.io/job/practice-numbers-senior-software-engineer.json","meta":{"generated_at":"2026-10-15T22:16:39Z","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":33767,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":2763798},"rest":"https://alion.io/mcp/rest/get_company?id=2763798"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpractice-numbers-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%2Fpractice-numbers-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%2Fpractice-numbers-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/practice-numbers-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpractice-numbers-senior-software-engineer"}]}
