It is regulated by the FCA, has tens\nof thousands of paying members, and is run by a team of fewer than 20 people. Every engineer\nworks with Claude\nCode every day.\nThe job\nYou own the code that moves the money: subscriptions and billing on Stripe (two accounts), the card with our card\nprocessor, the store and gift cards, pushes to members, the reporting data behind them, and our USA site. You take\nover these systems and make them better. You work beside our lead backend engineer, w\nho owns payments, Stripe,\ninfrastructure and the web today, and directly with the CEO.\nYour first 90 days\nTake over the subscription, billing and store services end to end, with a writtenmap of what runs where, whatalarms exist, and what fails silently today.\nShip the top change the CEO picks\nTake one job a person does by hand today, in finance, support or collections, and automate it.\nHow we work\nA small, excellent team, paid well on standard terms. No custom deals and no managers for their own sake.Smart people get a mandate, not instructions.\nYou get the problem and you own the answer.n estimate before anything starts, and the work fits the time agreed.You test it and read every word before it ships.\n“It should work” is not done.S hip small, measure, then decide. Something customers can see every week.\nOne source of truth per topic, written down.\nManual work is never a reason not to do something. We automate it.\nFewer cancellations, more revenue and less bad debt come first. Anything that moves none of them waits.","description_format":"text","description_chars":1618,"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":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cards & Card Issuing","Personal Finance Apps & Education"],"lifecycle":[{"event":"open","at":"2026-11-11T07:37:43Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:1","win:early"],"computed_at":"2026-11-11T09:13:37Z"},"pay":null,"html_url":"https://alion.io/job/bits-senior-backend-engineer-payments-and-cards","json_url":"https://alion.io/job/bits-senior-backend-engineer-payments-and-cards.json","meta":{"generated_at":"2026-11-11T09:13:37Z","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":15182,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":677791},"rest":"https://alion.io/mcp/rest/get_company?id=677791"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbits-senior-backend-engineer-payments-and-cards"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fbits-senior-backend-engineer-payments-and-cards"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fbits-senior-backend-engineer-payments-and-cards"},{"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/bits-senior-backend-engineer-payments-and-cards\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbits-senior-backend-engineer-payments-and-cards"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4059709}},{"tool":"search_jobs","arguments":{"company":"getbits.app","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4059709},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
