It combines deep revenue and accounting expertise with the agents and applications needed to run revenue work end to end. Tabs understands customer and contract context, applies accounting logic, and executes critical workflows with built in controls, auditability, and human oversight. With Tabs, finance teams can move from manually managing revenue workflows to directing outcomes while the system executes the work.\nAbout the Role\nTabs is seeking a Senior Software Engineer specifically focused on building out custom payments workflows and integrations with payment service providers. As a member of our early-stage startup, you’ll have the opportunity to shape the direction of the company and make a meaningful impact on our success.\nHow We Work\nWe work hard. Two-week sprints based on defined goals with short feedback cycles. Built around intra-month product releases.\n\nWe work smart. Get in front of the customer, use both data and customer feedback to drive decisions, while keeping the bigger picture in mind. Hash out your ideas with other smart engineers who are dedicated to coming up with great solutions.\n\nWe work together. In-office culture with people you want to work with. Lots of whiteboard space. Expense lunch and dinner when in the office, and bagel Fridays!\n\nWhat You'll Do\nBe our payments expert as we build out systems that support multiple PSPs and other exciting similar payment opportunities. There are a lot of moving pieces that have to line up and you’ll own and drive significant projects that make it work.\n\nWork closely with other engineering teams to make sure the entire revenue lifecycle delivers a frictionless billing and payment experience for our merchants and their customers.\n\nPut AI to work everywhere it can move the needle, whether it’s product automation, business process improvement, or the team’s day-to-day workflow. We're dealing with our customers' revenue, so we use AI aggressively while also getting the numbers exactly right.\n\nLevel up the engineers around you. The team's about 30 today with a good range of experience and backgrounds, and we’re growing fast. You'll be someone people look up to as you set the technical bar, mentor and learn from those around you, and shape the kind of culture we want as we get bigger.\n\nAbout You\nYou’ve been building software professionally for 5+ years and shipped high-impact products with a specialization in building payments systems with at least a couple of Payment Processors.\n\nYou've led big, complex system design before, ideally somewhere that was moving and growing fast.\n\nYou're hands-on with modern languages and frameworks. You still like being in the code, not just talking about it.\n\nYou've got a strong grip on the fundamentals like algorithms, data structures, and distributed systems. You know how to apply them where they actually matter.\n\nYou’re genuinely excited about AI, already using it, testing its limits, and keeping up with the latest advancements.\n\nAmbiguity doesn't slow you down. You thrive in the early, undefined stage of a problem where you get to shape the answer rather than follow a spec.\n\nYou're the kind of engineer other engineers want to learn from, and you truly enjoy that aspect of the role.\n\nNot sure you tick every box? Apply anyway. If you're excited about what we're building, we want to hear from you.\n\nTech & Tools\nDay to day, you'll be in Next.js, Nest.js, TypeScript, and React.\n\nYou'll have a wide range of GenAI systems and tooling to build with, and a lot of freedom in how you use them.\n\nWe run on AWS and Vercel, with Datadog and Sentry for observability, and Stripe and Plaid powering payments.\n\nFor everything else, we use modern tools like Slack, Notion, Linear, and Google Workspace.\n\nLocation: NYC, 5 days onsite\nPerks and Benefits (Full-time Employees)\nCompetitive compensation and equity\n\nUnlimited PTO\n\nUp to 100% employer covered monthly healthcare premium (medical, dental, vision)\n\nLunch provided via Sharebite, plus dinner for any later in office days.\n\nParental leave up to 12 weeks\n\nTax free commuter and parking benefits\n\nVoluntary insurances (Life, Hospital, Critical Illness, Accident)\n\nEmployee Assistance Program (Rightway)\n\nFree One Medical Membership\n\n401k\n\nTabs is an equal opportunity employer. We welcome teammates of all identities and do not discriminate on the basis of race, ethnicity, religion, gender identity, sexual orientation, age, disability, veteran status, or any other protected characteristic. We’re committed to creating an environment where everyone can grow, contribute, and feel comfortable being themselves.","description_format":"text","description_chars":4699,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Equity","Parental leave","Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Billing & Subscription Management","Financial AI","Document AI","Accounting & Tax Software"],"lifecycle":[{"event":"open","at":"2026-07-14T19:48:16Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"Filed H-1B visas in the last two years","filings_12m":0,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.732,"p_room":0.36,"age_days":94,"expected_fill_days":55,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/tabs-senior-software-engineer-payments","json_url":"https://alion.io/job/tabs-senior-software-engineer-payments.json","meta":{"generated_at":"2026-10-18T13:39:34Z","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":20233,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":717047},"rest":"https://alion.io/mcp/rest/get_company?id=717047"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftabs-senior-software-engineer-payments"},{"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%2Ftabs-senior-software-engineer-payments"},{"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%2Ftabs-senior-software-engineer-payments"},{"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/tabs-senior-software-engineer-payments\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftabs-senior-software-engineer-payments"}]}
